Chapter 1 - Introduction

1.1 General Description

The VMX Series is a digitally programmable solid-state reduced voltage soft starter. Its six SCR design features a voltage/current ramp with an anti-oscillation circuit for smooth load acceleration. The SCRs are sized to withstand starting currents of 350% for 30 seconds and up to 600% for 10 seconds. The VMX Series features smooth, stepless ramp control, which reduces motor inrush current and excessive wear on the mechanical drive train components. The VMX Series includes a programmable keypad for setting operating parameters for the ideal starting cycle and protection features, plus easy to understand diagnostic LEDs. Starting torque, ramp time, current limit, dual ramp, and Decel control are standard features on the VMX Series, as well as the integrated Batch Process Timer and Time Clock Controller used for automated applications. By simply adjusting the unit‟s starting torque, ramp time and current limit functions, the starting electrical characteristics of the motor can be matched to the mechanical characteristics of the drive train for controlled acceleration of the load.

The VMX Series includes solid-state electronic overload protection in addition to numerous other protective features. It requires 120VAC

(220VAC optional) control power and uses dry contact inputs for Start /

Stop control. Programmable auxiliary contacts and provisions for interlocking are also included.

1.2 Sizes and Ratings

The Motortronics VMX Series starters are current rated controllers.

Max. Amp ratings are for continuous duty and must not be exceeded.

Always check the motor nameplate FLA and Service Factor to ensure proper sizing.

Each size has an adjustable current range from 50% to 100% of the

Max Amp rating. Table 1.2 shows the Current Ratings available.

1.2.1 Selecting for Service Factor Utilization

Many NEMA design motors include a design rating referred to as Service Factor (SF) that may allow continuous operation above the nameplate current rating. If using this Service

Factor, the VMX Series starter must be sized for the total amps used. For proper selection of the VMX Series starter when using SF continuously, multiply the nameplate FLA by the stated Service Factor, or use stated Service Factor Amps

(SFA) if listed on the nameplate. The following excerpt is from the NEMA MG-1 standards for AC Motors that describes the issues concerning the use of Service Factor ratings.

"When an induction motor is operated at any service factor

greater than 1.0, it may have efficiency, power factor and speed different than those at rated load. Locked rotor torque and current and breakdown torque will remain the same. A motor operating continuously at any service factor greater than

1.0 will have a reduced life expectancy compared to operating

at its nameplate horsepower."

When using this feature, simply program the VMX Series

Service Factor (F002) to the nameplate rating. (See section

5.6.1.) All other adjustments to the protection circuits are done automatically within the VMX Series.

1.2.2 Selecting for Across the Line Bypass

If you need to be able to start the motor Across-the-Line when the VMX Series electronics are out of service, the starter can also be selected based upon the rating of the Bypass

Contactor. Some users may also elect to size their Bypass

Contactors per NEMA guidelines. When doing this, please refer to the Product Selection Guide for details and notes, and see Appendix 5 for special considerations

regarding Overload Protection.

 Note:

The

VMX…-BP Series starters include the ability to connect a dry contact directly to the Bypass Contactor coil control circuit. These terminals are covered when shipped and should be used ONLY when necessary for Emergency Bypass operation and with an external Overload Relay. See Appendix 5 for additional information.

No field wiring to these terminals is necessary if this feature is not used.

VMX Digital Solid State Soft Starter User Manual 4 | P a g e

Chapter 2 - Installation

2.1 Receiving and Unpacking

Upon receipt of the product, you should immediately do the following:

 Carefully unpack the unit from the shipping carton and inspect it for shipping damage. If damaged, notify the freight carrier and file a

claim within 15 days of receipt.

 Verify that the model number on the unit matches your purchase order.

 Confirm that the ratings nameplate on the unit matches or is greater t han the motor‟s HP and current rating with which it is to be used.

2.2 Choosing a Location

Proper location of the VMX Series is necessary to achieve specified performance and normal operational lifetime. The VMX Series should always be installed in an area where the following conditions exist:

 Ambient operating temperature:

Panel (open chassis) unit: 0 to 50°C (32 to 122°F)

Enclosed unit: 0 to 40°C (32 to 104°F)

 Protected from rain, moisture and direct sun.

 Humidity: 5 to 95% non-condensing

 Free from metallic particles, conductive dust and corrosive gas.

 Free from excessive vibration. (below 0.5G)

 Open panel units must be mounted in the appropriate type of enclosure. Enclosure size and type must be suitable to dissipate heat generated by the soft starter and any other components mounted inside with it.

 Units with –BP Bypass Contactors produce less heat than units without. Throughout all sizes, maximum heat dissipation of the

VMX…-BP Series electronics, contactor coils and fans is less than

50W.

 Units without the –BP Bypass Contactor (optional on 210A and above), must have ventilation adequate for heat dissipation of the

SCRs. This is estimated at 4.5 watts per running load amp. For example, a 200HP 460V motor with 240FLA, the maximum wattage loss of a starter w/o bypass will be 240 x 4.5, or 1080 watts. The enclosure ventilation (or air conditioning) must be capable of dissipating the amount of heat due to this wattage loss to maintain the enclosure below temperature limits.

 Care should always be taken to maximize the available space inside of the enclosure. See section 2.5.1 or contact factory for assistance in sizing enclosures.

2.3 Initial Unit Inspection

Make a complete visual check of the unit for damage that may have occurred during shipping and handling. Do not attempt to continue installation or start up the unit if it is damaged.

 Check for loose mechanical assemblies or broken wires which may have occurred during transportation or handling. Loose electrical connections will increase resistance and cause the unit to function improperly.

 Prior to beginning the installation, verify that the motor and VMX

Series unit are rated for the proper amperage and voltage.

VMX Digital Solid State Soft Starter User Manual 5 | P a g e

2.4 SERVICE WARNING!

Do not service equipment with voltage applied! The unit can be the source of fatal electrical shocks! To avoid shock hazard, disconnect main power and control power before working on the unit. Warning labels must be attached to terminals, enclosure and control panel to meet local codes. Use Lock Out tags such as the one shown when servicing equipment.

2.5 Mounting and Cleaning

When drilling or punching holes in the enclosure, cover the electrical assembly to prevent metal filings from becoming lodged in areas which can cause clearance reduction or actual electrical shorts. After work is complete, thoroughly clean, vacuum the area, and re-inspect the unit for foreign material.

2.5.1 Clearances

Make sure there is sufficient clearance all around the unit for cooling, wiring and maintenance purposes. To conserve panel space, the VMX

Series

– BP models were designed for close vertical clearances of only

1 inch (25mm) on either side. A minimum horizontal clearance of 4”

(100 mm) on the top and bottom is necessary to maximize effective airflow and cooling. Also the unit must be installed with its heat sink ribs oriented vertically and running parallel to the mounting surface. Keep in mind that these are minimums. Wiring may require more clearance, particularly on the bottom.

WARNING!

Remove all sources of power before cleaning the unit.

In dirty or contaminated atmospheres, the unit should be cleaned on a regular basis to ensure proper cooling. Do not use any chemicals to clean the unit. To remove surface dust use clean, dry compressed air only, 80 to 100 psi. A three-inch, high quality, dry paintbrush is helpful to loosen up the dust prior to using compressed air on the unit. Do not use wire brushes or other conductive cleaning materials

2.6 Power Terminations

Load

All line and load power terminations are to be made to tin plated copper

Bus Tabs located on each unit. Bus tabs are pre-drilled to accept industry standard bolts. Some sizes come with saddle clamp terminals, however the connecting lugs are the responsibility of the user.

Motortronics recommends using crimp-on lugs, although mechanical lugs are suitable as well. The following diagrams show sizes of the bus tab holes and critical spacing between them for determining the size of lug that can be used.

Chapter 3 - Motor Overload Protection

MOTOR FLA (F001) must be programmed for unit to operate!

3.1 Solid State Overload Protection

The VMX Series Starter provides true U.L. listed I

2 t Thermal Overload

Protection as a built-in function of the main digital processor for maximum motor protection. It simulates the tripping action of a bimetallic overload relay, with the accuracy and repeatability of a digital control system. It is adjustable over a wide range and can be easily programmed for different trip curves.

(43% used)

3.1.1 Thermal Memory

The VMX Series microprocessor uses a sophisticated “Thermal

Register” in the digital memory to keep track of motor heating and cooling over time regardless of the start er‟s power status. By using nonvolatile memory, the VMX Series does not “forget” that the motor has been running even if power to the starter is turned off and turned back on. Continuous overload protection is provided based on the true thermal condition of the motor.

3.1.2 Thermal Capacity

The Thermal Register is displayed as a percentage. This percentage is the motor‟s remaining thermal capacity. The percentage value begins at

100, showing that the motor is cool (has 100% of its capacity available).

As the motor heats up or moves toward an overload condition, the percentage begins to drop. The Thermal Capacity is derived from the programmed motor nameplate Full Load Amps (FLA) in Function F001, the Service Factor rating in Function F002, and the Overload Trip Class in Functions F003 and F004. Setting these functions to the proper values provides maximum protection and eliminates nuisance tripping.

The Remaining Thermal Capacity can be viewed by using the UP or

DOWN arrow keys when in the Status Display mode. From the default

Phase A Current screen (dot on right side), press the UP arrow key 4 times to display [H100] meaning there is 100% of the Thermal Capacity

(H = Heat capacity) remaining in the motor. After starting or running, the motor will use this capacity and the display will show a lower number.

For example, after a cold start, the display may read [H065] which indicates that the motor has 65% of its thermal capacity remaining (35% used). The Status Display screens cycle back to the beginning, so the

Down arrow keys can access this display as well.

 3.1.2.a

Motor Full Load (FLA) Setting

Use Function F001 to enter motor FLA as indicated on the motor nameplate. (Do not calculate for service factor, this is programmed separately in F002).

 Note:

All VMX Series starters are shipped from the factory with F001 set to a default value of 0000. If F001 is left at the factory default, the unit will not operate. If the user attempts to start the VMX Series without entering the motor nameplate FLA, the starter will Fault and the display will read “nFLA” (no Full Load Amps).

3.1.3 Disabling the Overload Protection

The Overload Protection feature can be disabled if necessary. When using external devices such as Motor Protection Relays or when the

VMX Series is wired downstream from an existing starter, this feature can be disabled to prevent conflicts with external overload protection devices. When the VMX Series is controlling multiple motors, the builtin Overload protection must be disabled and individual thermal overload relays must be installed on the motor leads going to each motor (see appendix 5 for additional details). To disable the Overload Protection function, use F005.

WARNING!

Do NOT disable Overload Protection unless another Thermal Overload Protection

device exists in the circuit for all three phases. Running a motor without Overload

Protection presents serious risk of motor damage or fire.

 3.1.3.a

Manual Reset

The factory default setting is Manual Reset. This means that when the Overload Trip is activated, the starter cannot be restarted without pressing the Reset key. The Overload Trip will not reset until the motor cools down (see 3.1.3.d). The Manual Reset function is also “trip free”. Holding in the Reset key will not prevent the

Overload Trip from activating and protecting the motor.

 Note:

When the Overload Trip activates, the Overload LED will be on solid. When the motor cools down, the LED will begin to flash, indicating that the Overload Trip can be reset.

 3.1.3.b

Automatic Reset

If Automatic Reset is necessary, change from Manual Reset to

Automatic Reset by using Function F005. (See Section 5 for details). In this mode, a 3-wire control circuit will be capable of restart when the VMX Series has reset itself after the cool down period.

WARNING!

Two-wire control systems may restart without warning when Auto

Reset of the overload protection is selected. Extreme caution should be exercised. To prevent automatic restarting with 2-wire control systems, use external interlocking to provide sufficient warning and safety to operators. A Warning Label similar to that shown below (and the one provided in the packet with this manual) must be located where visible (on the starter enclosure and/or the driven equipment) as required by local code.

WARNING: MOTOR CONNECTED TO THIS EQUIPMENT

MAY START AUTOMATICALLY WITHOUT WARNING

VMX Digital Solid State Soft Starter User Manual 12 | P a g e

 3.1.3.c

Overload Protection During Bypass

When an integral Bypass Contactor is used to shunt power around the SCRs in the VMX Series

(as in the VMX…-BP version), overload protection is maintained as long as the VMX Series is directly controlling the contactor. No additional Overload Relay is

necessary for normal operation.

Caution:

If a Bypass Contactor is added by the user in the field (i.e. 210A units and above), care must be taken to ensure proper power routing to ensure functioning of the Overload protection. Consult factory for assistance.

 When the Bypass Contactor on a VMX…-BP Series has been selected to be used for Across-the-Line restart (reference section

1.2.3), supplemental overload protection may be necessary. For this application, refer to the External Overload Relay Applications supplement and wiring diagram in Appendix 5 and section 4.2.6.a.

 3.1.3.d

Dynamic Reset Capacity

The VMX Series includes the ability to dynamically track the

Thermal Capacity needed for a successful restart after an overload trip. It averages the Thermal Capacity consumed in the previous three successful starts, and calculates a Thermal Capacity to Start

(viewed in Function F059). After tripping on Overload, the Thermal

Reset will be allowed. If the display reads [ Inh] when attempting to reset an overload trip, it is indicating that the starter is Inhibited from being reset.

Refer to details of Function F071 for information on emergency override of lockouts such as this.

3.2 NEMA Class Trip Curves

NEMA Class trip curves are based on a common tripping point of 600% of motor Full Load Amps (FLA). Curves vary by the amount of time before the unit trips. As an example, a Class 20 curve will trip in 20 seconds at 600% of FLA. The factory default setting of Class 10 will trip in 10 seconds at 600% of FLA.

3.2.1 Dual Overload Trip Curves

The VMX Series Soft Starter provides two separate Overload Trip

Protection Curves, one for starting and one for running conditions. The starter‟s At-Speed detection circuit determines when the motor has reached full speed. When the At-Speed condition is reached, the overload trip curve will shift from the Start to the Run level, as programmed in Functions F003 and F004. See Section 5.6.1 for programming details.

3.2.2 Starting Overload Trip Curve

During the start mode, Overload Trip Curves are selectable from NEMA

Class 5 through Class 20 only. The default setting of Class 10 allows protection for the overload capacity of the soft starter as well as the motor. Use a higher Trip Class only if nuisance tripping occurs with the default setting.

VMX Digital Solid State Soft Starter User Manual 13 | P a g e

3.2.3 Running Overload Curve

During the Run mode, Overload trip curves are selectable from NEMA

Class 5, 10, 15, 20, 25, and 30. Program the appropriate curve according to the characteristics of your motor and load.

4.1 Power Connections

Referring to local code standards for wire sizing and length, connect power conductors to the unit input terminals marked L1, L2, L3 (R, S, T for IEC users). Connection points for units of 160A and below are saddle clamps suitable for stranded wire. Connection points for units of

210A and above are bus tabs with pre-drilled holes (see section 2). Use appropriate compression or mechanical lugs for termination to these bus tabs. Avoid routing power wires over the control board or display.

Connect the motor leads to the unit terminals marked T1, T2, T3 (U, V,

W for IEC users). If control power is present, but line power is disconnected from L1, L2, L3, the display will show [n3PH] indicating

“no 3 Phase”.

Caution!

Never interchange input and output connections to the unit. This could cause excessive voltage in the control logic circuit and may damage the unit.

4.1.1 Bypass Contactor

Bypass Contactors are integral (builtin) on all VMX…-BP (panel mount), and all VMX…–E (NEMA 12 enclosed) versions. See sections

3.2.1.c and 4.2.5 for more details on contactor control and overload protection details.

4.1.2 Power Factor Correction Capacitors

Power factor correction capacitors can be connected to motors controlled by VMX Series starters, however they must be off-line during ramping. Connect PFC capacitors to the Line side of the starter with a separate capacitor control contactor.

*Larger units (210A and above) can be ordered with fan cooling instead of

Bypass Contactors, but are intended for use in NEMA 1 ventilated enclosures only. Do not use the VMX starter in a sealed enclosure without a bypass contactor.

WARNING!

Never connect power factor correction capacitors on the load side of the unit. The SCRs will be seriously damaged if capacitors are located on the load side.

4.1.3 Grounding

Connect the ground cable to the ground terminal as labeled on the unit.

Refer to the National Electrical Code or your local Code for the proper ground wire sizing and be sure that the ground connector is connected to earth ground. In ungrounded systems, it is not necessary to connect a ground to the unit however local codes should always be consulted.

VMX Digital Solid State Soft Starter User Manual 15 | P a g e

4.1.4 Testing

The VMX Series can be tested with a load smaller than the motor it was originally selected to control, however additional steps must be taken to avoid tripping on Phase Current Loss. See section 5.6.9.a under “Phase

Loss Protection” for additional details on performing this task.

 Notes:

The unit cannot be tested without a motor or other test load connected to the load side of the unit. It may be necessary to use a load bank to test the unit without a motor.

 Line voltage will appear across the output terminals if there is no motor or load connected to the unit.

4.1.5 Lightning Protection

As with all electronic power controllers, protection from damage by lightning surges is recommended in areas where lightning is a significant problem. Stationary air gap lightning arrestors should be considered and utilized on the input power source. The best method of protection is to have an Isolation Contactor in front of the starter that is open when the soft starter is not in use.

4.2 Control Connections

Control connections on the VMX Series starter are divided into 2 groups. With the unit oriented vertically, TB1 is a 12-point DC terminal block (on the left), and TB2 is a 10 point AC terminal block (on the right side). These are removable terminal blocks for ease of connection and servicing, and are provided with different spacing (pitch) between the header pins so they are not interchangeable. Following are descriptions of control connection points.

 Note:

 4.2.2.a

Seal In Contact

The VMX Series uses an internally prewired “seal-in” contact around the Start button (Terminals 1 and 2). No external relay or auxiliary output connection is necessary.

4.2.3 Two Wire Control: Relay / PLC Connection

An alternate connection for automated or unattended operation replaces the start/stop push buttons by connecting a dry (voltage free) maintained contact closure between terminals 1 and 3 as shown in

Figure 4.2.3. When this contact is closed, the VMX Series starter will start and run. When it is opened, it is the same as a Stop command.

 4.2.3.a

Automatic Functions and 2 Wire Control

If using the Time Clock functions (F032-F039) or Auto Reset functions (F052

– F053), special consideration must be given to using 2 wire control. Refer to Appendix 3 for additional details and information on time clock functions, and section 5.6.9 for details on using Auto-Reset functions.

 Note:

When a maintained contact is used for start/stop it is advisable to set the overload relay to the manual reset position. This will prevent the motor from restarting if the thermal overload trips and then cools down.

CAUTION!

Control Terminals 1-10 of TB1 are configured using solid state devices powered internally with a 24VDC power supply. To prevent damage to the VMX Series control board, use dry (unpowered) contact closures only when connecting to these terminals.

If existing 120VAC or other powered control circuit must be interfaced, use isolating relays or control the VMX Series with 2 wire control as shown above.

4.2.4 Interlock Connection

TB1 provides a connection point for an external dry (voltage free) N.C.

(Normally Closed) interlock device between terminals 4 and 5.

Examples where this interlock connection would be used include low oil, high temperature, or excess vibration dropout from user supplied devices. A factory-installed jumper is provided which allows the VMX

Series unit to operate if external interlocks are not used. If this jumper is removed and an interlock is not used, the VMX Series unit will not function.

4.2.5 Enabling the Dual Ramp and Jog Features

TB1 includes provisions for enabling the Dual Ramp and Jog functions by using external contact closures. Both features use a common

+24VDC from Terminal 7 however, they can be used independently of each other or together. See sections 5.6.2 and 5.6.3 for full function descriptions and setup.

 4.2.5.a

Dual Ramp Command

Closing a dry (voltage free) contact between TB1, terminals 6 and 7 will enable Ramp 2, and the VMX Series starter will respond to the settings for Ramp 2 in F015 - F018. If no contact closure is present, the VMX Series starter defaults to the Ramp 1 parameters (F011

–

F014). See Section 5.6.2.a for setup of the Dual Ramp Feature.

The Dual Ramp feature is useful in instances where the load changes significantly. Example: a loaded or unloaded conveyor belt.

The characteristics for starting an unloaded conveyor can be programmed for ramp 1. The characteristics for starting a loaded conveyor can be programmed for ramp 2. Ramp 2 can also be programmed for Full Voltage / Across-the-Line starting by setting the ramp time to 0 and Current to 600%.

Dual Ramp is also useful in 2-speed motor applications. Simply use an auxiliary contact from one of the speed contactors to select

Ramp 2 so that separate ramp profiles can be used.

 4.2.5.b

Jog / Remote Command

Connecting a dry (voltage free) contact between TB1, Terminals 7 and 8 will enable the Jog feature. A Start command (Run Command or Start button) is required to activate the Jog feature. See Section

5.6.3 for setup of the Jog Function.

The Jog feature can be used for tasks such as lining up machines for blade or bit changes or inching belts along to check tracking.

This input is also used to change the function of the Serial

Communications port control through F068. For additional information, see instructions of that function in section 5.6.11.

 4.2.5.c

Using Both Commands

It may be useful to initialize the Ramp 2 and Jog command simultaneously when jogging. If this is the case, terminals 6 and 8 can be jumped together and controlled with one contact closure to

Terminal 7 (the common 24VDC).

4.2.6 PTC Thermistor Input

The VMX Series starter is provided with input terminals for connecting a

PTC (Positive Temperature Coefficient) Thermistor that may be imbedded in the motor. These are specialized resistors imbedded in some motor windings that increase in resistance as the temperature increases. When the VMX Series detects that the PTC input resistance is too high, it initiates a PTC trip, and displays [ PTc ] on the readout.

This is independent of the Thermal Register overload current protection and provides supplemental protection for high motor ambient temperature applications. Terminals for this input are provided with a factory jumper that must be removed if the PTC input is used. These are

Terminals 9 and 10 located on TB1.

PTC resistors are also found in other devices such as bearings, air receivers, oil or coolant reservoirs and air discharge systems that may require shutdown of the motor.

PTC Resistor Values:

The resistance must be greater than or equal to 750



at 25ºC. If multiple resistors are used in the motor, the sum of all resistors in series must equal or exceed this value.

External Over Load Relay Connection

If an external Over Load Relay (OLR) is used (see Section 3.1.3.c and Appendix 5), connect the NC aux. contact of the OLR to the

PTC input after removing the jumper. When the external OLR trips, the contact will open, opening the resistance input to the PTC circuit

(the resistance goes to infinity). This indicates an immediate Over

Load to the starter, which trips and displays [ PTc ] on the readout to differentiate from the internal Thermal Over Load trip. If multiple

OLRs are used, i.e. multiple motors controlled by the same VMX

Series starter, simply wire the Aux Contacts in series as shown in

Figure 4.2.6.a. See Appendix 5 for additional information.

 Note:

An Emergency Stop Push Button or any other field device may be wired to the PTC input using NC contacts. When the contacts open, the starter will detect it as a PTC trip. Even if a PTC is used in the motor, field devices can still be added as long as the total circuit resistance is not exceeded.

 This feature is especially useful when using Decel Control because it will immediately shut off power to the motor even if Decel is active. If used this way, instruct the users as to the trip indication issues (i.e. the display will show [ PTc ] and the Overload LED will be on).

4.2.7 Fault Signal

An optically isolated Triac output is dedicated as a fault indicator on

TB1, terminals 11 and 12, labeled “Opto”. The output Triac switch is rated for 10 - 250 VAC/DC, 50 mA (maximum). If the three programmable Output Auxiliary Relays are being used for other functions, this output can easily be hooked up to a PLC or small external relay to provide a Fault signal. This Fault Output operation is permanently fixed at “Any Trip”, duplicating the Relay setting 16 as shown in Table 5.6.10.

This output is permanently set to this function and is not

programmable.

4.2.8 Output (Auxiliary) Relay Contacts

Three programmable auxiliary relays are on TB2. The VMX Series starter comes with three programmable dry relay output contacts.

Outputs 1 and 2 are Form C (SPDT), with a Common, N.O. and N.C.

Output 3 is a Form A, (SPST), N.O. contact. It is not necessary to use the programmable output auxiliary relays in the Start / Stop circuit. An internal seal-in relay is provided elsewhere (see 4.2.2.a above).

Motortronics recommends fusing all outputs with external fuses.

The relays are rated for 240 VAC, 5 A and 1200 VA.

Factory default settings for these relays are as follows:

 AUX 1 – Run / Stop (see F060).This contact changes state upon a

Start command, returns to normal on Stop (or Begin Decel if active).

 AUX 2 – At-Speed / Stop (see F061).This contact changes state upon the VMX Series detecting At-Speed, and returns to normal on

Stop. At-Speed is determined by the VMX Series detecting the current dropping after reaching End-of-Ramp, or a maximum of 30 seconds after Start.

 AUX 3 – Any Trip (see F062) This contact closes when any trip condition 5

– 15 (as defined in Table 5.6.10) occurs.

All relays can be reprogrammed for a wide variety of functions.

See Section 5.6.10 for additional relay programming details.

4.2.9 Bypass Contactor Control

VMX…-BP version (and NEMA 12 enclosures) starters, an internal dedicated connection is used at the factory for automatically controlling the Bypass Contactor. Field wiring for Bypass Contactor operation is not required.

 4.2.9.a

Independent Bypass Contactor Control

The

VMX…-BP Series starters use standard industrial contactors that can be controlled independent of the starter electronics if necessary. When doing so, it is necessary to size the starter based upon the ATL (Across-the-Line) selection chart so that the contactors are rated for ATL duty instead of normal Shunt Duty.

(see section 1.2.3). Supplemental overload protection will be required (see section 3.1.3.c).

Units have external terminal blocks marked for this purpose (see

Appendix 5 for drawings). A dry (voltage free) contact closure between these terminals will close the bypass contactor immediately. The Bypass Contactor coil voltage is the same as the control voltage (120VAC unless the optional 240VAC control is specified), and the voltage on these terminals is the same as the coil voltage.

No field wiring is necessary to these terminals if this feature is

not used.

For all other styles of VMX Series, the At-Speed signaling can be programmed into any of the three Output relays (section 4.2.8 and

Table 5.6.10).

5.4.5 Fault Mode

The Fault Mode Display provides information to the operator when a fault occurs and allows the operator to review fault history. Refer to

Section 7 for details. Fault codes are displayed by 3 alpha characters.

The first and second characters (reading left to right) are the initials for the applicable English-language fault name. The third or right-most character can be either A, c, or d to denote when the fault occurred. “A” denotes Acceleration

. “c” denotes Constant speed. “d” denotes Decel.

Example: Figure 5.4.5

Viewing a Fault and History

[ PLA.] Indicates that there was a Phase Loss during

Acceleration. The Decimal point on the right signifies that this is the current fault.

Press the UP Arrow key

[IBc]

Displays the previous fault, a Phase Imbalance during Constant Speed (running)

Press the UP Arrow key

[ oLc] Displays the oldest fault, an Over Load trip during

Constant speed (running).

Press [RESET] key

This Fault History can only be accessed during a fault condition. While the active fault number is being displayed, use the Up and Down Arrow keys to scroll through the Fault History. An additional Fault History complete with Time and Date stamps is also available for viewing at any time in F085 through F093.

 5.4.5.a

Resetting Faults

Once a fault condition has been corrected, pressing the Reset key will return the readout to the Status Display mode. To reset faults, press the [RESET] key on the keypad. Alternatively, most faults will reset upon removal and return of control power. Over Load trips will

NOT be reset in this way unless sufficient time has passed for the

Thermal Register to regain sufficient capacity for a successful restart (see section 3.1).

 5.4.5.b

Remote Reset

Because most trips can be reset by removing control power, remote reset can be accomplished this way. A NC remote contact (or pushbutton) can be placed in the control power supply to A1 or A2 and opened to facilitate a trip reset. See figure 5.4.5.b for a suggested connection.

VMX Digital Solid State Soft Starter User Manual 28 | P a g e

 5.4.5.c

Automatic Reset

The VMX Series starter provides for automatic reset on certain noncritical faults and Over Load. For non-critical fault resets, see section 5.6.9 for program details of F052 and F053. For automatic

Over Load reset, see section 3.1 and 5.6.1 for programming details.

 5.4.5.d

Lockout Functions

Lockout functions such as Minimum Time Between Starts and

Starts per Hour are not true fault conditions. They are based on the internal Real Time Clock (RTC). When control power is removed, the RTC value is quickly stored. Upon return of power, the timer values are updated from the RTC for elapsed time. If the Lockout

Time has not expired, the VMX Series cannot be started. To reset the Lockout Times for emergency restart, see section 5.6.12, under

F071.

 5.4.5.e

Changing to Default Screen During Fault

In some cases it may be necessary to alter programmed parameters in order to test or make changes to clear a fault (such as Phase Loss) or to view the more detailed fault history in F085

–

F097. To accomplish this, you must get to the Status Screen so the

Fn button becomes active. When in a Fault Screen, pressing the

Right or Left Arrow buttons will take you to the Status Screen. From there, you can press the [Fn] key to enter the Programming Mode and move to different functions.

MOTOR FLA (F001) must be programmed for unit to operate!

5.6 Function Descriptions

Your VMX Series starter is set at the factory with typical default settings that perform well in most applications. Following are detailed descriptions of each Function and the factory default settings.

5.6.1 Motor and Overload Function Descriptions

F001= Motor FLA

Factory Setting = 0

Range = 50 - 100% of Unit Max. Current.

Set the value of this function to the motor nameplate Full Load

Amps (FLA). Adjustments for service factor are not necessary when programming this function. (See note below). If the motor nameplate FLA is not available, use typical values as shown in

NEC, NEMA standard MG-1 or other reputable third party source (motor manufacturer, etc.).

 Note:

To prevent adjusting the settings beyond the starter Max Amp rating, the range of adjustment for the Motor Nameplate FLA will vary in accordance with the Service Factor as programmed into

F002. At the default setting of 1.0SF, the full range of adjustment from 50 - 100% of the Max Amp rating is available. As the Service

Factor is increased, the FLA range will drop by an equal ratio. For example if F002 = 1.15 (a 1.15 Service Factor), the maximum FLA programmable into F001 will be limited to 85% of the starter Max.

Amp rating (100% - 15%).

F002 = Service Factor

Factory Setting = 1.0 S.F.

Range = 1.00 - 1.30

Set value according to the Service Factor (SF) data provided on the motor‟s nameplate. This value affects several protection features so it must be accurate. Setting the SF too high may result in motor damage in an overload condition. Setting SF too low may cause nuisance trips however; a 1.0 SF setting is safest if SF is unknown.

 Note:

The combination of F002 and F001 (FLA x SF) cannot exceed the

Unit Max Amp rating. If when programming F002 you are not allowed to raise the setting, the combined total has been exceeded.

F003 = Overload Class During Start

Factory Setting = 10 (Class 10)

Range = NEMA / UL Class 5 - 20

Set value to the motor protection overload class required for the application. It is recommended that you try the factory setting first. (If possible, keep values for F003 and F004 the same.)

Increase F003 above F004 only if nuisance tripping occurs during start. See Section 3.2 for details on trip curves.

VMX Digital Solid State Soft Starter User Manual 36 | P a g e

F004 = Overload Class During Run

Factory Setting = 10 (Class 10)

Range = 5 - 30 NEMA / UL Class

Set value according to the instructions provided by your motor / equipment manufacturer. This trip curve will not be enabled until the motor has reached full speed.

F005 = Overload Reset

Factory Setting = 0 (Manual)

Range = 0

– 2

Set value to determine starter behavior after an overload condition has cleared.

When set to 0 = Manual, the operator must press the [RESET] key before restarting the motor. Once the motor windings have cooled sufficiently AND the [RESET] key is pressed, the unit will accept a restart command.

When set to 1 = Automatic mode, and once sufficient time has elapsed allowing motor windings to cool, the motor will be restarted upon a start command. If 2-wire control is used, the unit will restart immediately.

When set to 2 = Disabled Overload, the VMX Series will not trip on Motor Thermal Overload. This is provided for applications where either an external Overload Relay or Motor

Protection Relay is used, or where multiple motors are connected and each one requires having an individual Overload

Relay. See Appendix 5 for more details.

WARNING:

Setting F005 = 1 (Automatic) may present significant operational risk.

When F005 = 2 (Disabled Overload), a separate external thermal overload protection device must be in the circuit.

 Note:

Because of the risk of fire or equipment damage, cycling control power will NOT reset an Overload Trip. If F005 = 2 (Automatic

Reset), cycling control power will allow reset ONLY if the Thermal

F006 - F009 = Reserved

VMX Digital Solid State Soft Starter User Manual 37 | P a g e

5.6.2 Starting Mode

The VMX Series is capable of several different starting modes, but is set from the factory for the most common applications. A second ramp profile is available for use should it be required. Unless wired to do so, the VMX Series defaults to Ramp 1. This section describes functions for

Ramp 1, with references to function numbers that do the same thing for

Ramp 2 (if required). Refer to Appendix 2 for a detailed description of the differences in Ramp Profiles and their uses. All current percentages are based on the Motor FLA as programmed in F001.

F010 = Ramp Profile Selection

Factory Setting = 1

Range = 1

– 4

This Function selects the type of Ramp Profile desired. Ramp profiles can be either Voltage Ramp or Current Ramp. See

Appendix 2 for details. Each Ramp Profile consists of 3 settings:

Initial Torque, Ramp Time and Maximum Current Limit.

Because there are two ramps available, there are 4 settings to cover the combinations of profiles possible. If you are not using the 2 nd

ramp, the VMX Series will ignore all settings in reference to Ramp 2.

 Note:

When either Ramp is set to “Voltage Ramp”, the corresponding

“Initial Torque (Current)” setting is ignored. Conversely, when set to

“Current Ramp”, the “Initial Torque (Voltage)” is ignored.

VMX Digital Solid State Soft Starter User Manual 38 | P a g e

F011 = Initial Voltage of Ramp 1

Factory Setting = 60%

Range = 0 - 100%

Sets the initial voltage of ramp 1 when F010 = 1 or 3. The initial torque level should be set to provide just enough torque to make the motor shaft begin to rotate while preventing torque shock damage to mechanical components.

F012 = Initial Current of Ramp 1

Factory Setting = 200%

Range = 0 - 600%

Sets the initial current of ramp 1 when F010 = 2 or 4. The initial torque level should be set to provide just enough torque to make the motor shaft begin to rotate while preventing torque shock damage to mechanical components.

F013 = Accel Ramp Time of Ramp 1

Factory Setting = 10 seconds

Range = 1 - 120 seconds

Sets the time between the initial torque set with F011 or F012 and either the Max Current Limit set with F014 or full output voltage. Set the time to enable soft starts without stalls. Also, consider the motor‟s application. For example, centrifugal pumps may require a shorter ramp time.

 Note:

Ramp time is affected by the following conditions:

1. Current limit will extend the ramp time if the motor does not reach full speed while in current limit mode.

2. Anti-oscillation circuit may shorten the ramp time if the motor reaches full speed before end of ramp.

F014 = Max Current Limit of Ramp 1

Factory Setting = 350%

Range = 200 - 600%

Sets the maximum motor current that the VMX Series starter will allow during Ramp 1. This limit applies to both voltage and current ramping. Current will be limited to this setting until either the motor reaches full speed or the over load protection feature trips (F003).

VMX Digital Solid State Soft Starter User Manual 39 | P a g e

 5.6.2.a

Ramp 2 (user-optional ramp)

This ramp is selected by closing the input for Ramp 2, TB1

– terminals 5 & 6 (see section 4.2.5). If this input is left open, the VMX

Series will respond only to Ramp 1 settings as listed above. Since ramp 2 is always used as an alternate to the default Ramp 1, different combinations of ramp profiles can be selected in F010.

Refer to Appendix 1 for additional information on ramp profiles.

F015 = Initial Torque (Voltage) of Ramp 2

Factory Setting = 60%

Range = 0 - 100%

Sets the initial voltage of Ramp 2 when F010 = 1 or 4. The initial torque level should be set to provide just enough torque to make the motor shaft begin to rotate while preventing torque shock damage to mechanical components.

F016 = Initial Torque (Current) of Ramp 2

Factory Setting = 200%

Range = 0 - 600%

Sets the initial current of Ramp 2 when F010 = 2 or 3. The initial torque level should be set to provide just enough torque to make the motor shaft begin to rotate while preventing torque shock damage to mechanical components.

F017 = Accel Ramp Time of Ramp 2

Factory Setting = 10 seconds

Range = 1 - 120 seconds

Sets the time between the initial torque set with F015 or F016 and either the Max Current Limit set with F018 or full output voltage. Set the time to enable soft starts without stalls. Also consider the motor‟s application. For example, centrifugal pumps may require a shorter time. See notes for F013 for more details.

F018 = Max Current Limit of Ramp 2

Factory Setting = 350%

Range = 200 - 600%

Sets the maximum motor current that the VMX Series starter will allow during ramp 2. (This limit applies to both voltage and current-type ramping.) The current will be limited to this setting until either the motor reaches full speed or the over load protection feature trips (F003).

 Note:

Ram p 2 is often useful as a “bump start” or as a temporary Acrossthe-Line start mode. Consult Appendix 1 for details.

VMX Digital Solid State Soft Starter User Manual 40 | P a g e

5.6.3 Jog Mode

The Jog Function is another user optional feature and is controlled by closing the input on TB1 Terminals 6 and 7. If this input is left open, the

VMX Series will ignore all Jog settings. Engaging the Jog feature along with the Start / Run Command provides an output from the SCRs, but will not continue ramping to full acceleration. This feature can Jog the motor at either a preset Voltage (F019

– F021) or a preset Current

(F021) depending upon the settings of the Ramp Type from F010, and can be initiated along with Ramp 1 or Ramp 2 (see Dual Ramp Select,

Section 4.2.5 and 5.6.2.a). It is also sometimes useful to use Jog in combination with Ramp 2, see section 4.2.5.c.

Note: Jog functions may become disabled by Comm port function F068 setting 3.

F019 = Voltage Jog

Factory Setting = 50%

Range = 5 - 100%

Sets the voltage level of the Jog feature and is typically used to check rotation, alignment, or to slowly move a load into position.

Jogging at a set voltage has no current control so the duration of the applied voltage must be limited to prevent excessive motor heating.

5.6.4 Kick Start Mode

Kick Start applies a pulse of voltage to the motor producing a momentary “kick” of high torque to break the motor load free from high friction or frozen components. This pulse is limited to 2 seconds.

F022 = Kick Start Voltage

Factory Setting = 0 (Disabled)

Range = 10 - 100%

When F022

≠ 0, a voltage “pulse” is applied before the initial torque setting of F011 (or F012 if Current Ramp). This sets the voltage level and the duration of the pulse is set by F023. This setting should be higher than F011 (except for Dwell Starting, see below) and high enough to provide a benefit in the worst starting condition.

F023 = Kick Time

Factory Setting = 0.8 seconds

Range = 0.1 - 2 seconds

Sets the duration of time the Kick Start voltage is applied.

 5.6.4.a “Dwell” operation using Kick Start

In some applications such as chain drive machinery, the Kick Start feature can be used to slowly take up slack in the drive chain before applying full torque. This is referred to as “Dwell Starting” because the torque output stays low for a short time. To take advantage of this feature, simply set the Kick Start to the same level as the Initial

Torque setting. This will only work in Voltage Ramp mode.

 Note:

Do not use the Kick Start feature unless you determine that you need it. Using this feature may eliminate many of the mechanical and electrical benefits of using a Soft Starter.

5.6.5 Pump-Flex



Decel Mode (F025 through F028)

Pump-Flex



deceleration is a feature of the VMX Series Soft Starter that slowly decreases the applied voltage to the motor when a stop command is given, resulting in a gentle decrease in motor torque.

Deceleration provides a way to extend the stopping time so that abrupt stopping does not occur. Deceleration is useful with centrifugal pumps, material handlers, and conveyors where abrupt stopping could be damaging to the equipment and/or load.

SEE APPENDIX 2 AT THE END OF THIS MANUAL for typical Pump-

Flex



Decel feature applications and more detailed descriptions of the following functions.

F024 = Deceleration Ramp

Factory Setting = 0 (Disabled)

Range = 0

– 2

When F024 = 0, the deceleration feature is disabled.

When F024 = 1, the deceleration feature is enabled AND the overload protection feature (F003 - F005) remains active (power off on

OL trip).

When F024 = 2, the deceleration feature is enabled and deceleration will continue even when an overload condition trips.

Full Spe e d

WARNING!

Setting F025 = 2 presents significant risk of over-heating the motor beyond its design limits which could result in motor damage and fire hazard. Do this only in circumstances where

the potential for mechanical damage outweighs the risk of motor damage.

 Note:

When using the Decel function, count these cycles as additional

Caution!

Decel is THE OPPOSITE of braking. Enabling the Decel feature will make the motor take

LONGER to stop than if it were simply turned off.

5.6.6 Restart Delay

The VMX Series can be programmed to delay restarting upon restoration of line power after an outage. This allows multiple units to be programmed to restart at staggered times in an effort to avoid causing additional problems with the power supply system. Another term for this is “Sequential Start Delay”.

F028 = Restart Delay Time

Factory Setting = 0 (Disabled)

Range = 0 = Disabled (no delay), or 1 - 999 seconds

Sets a delay time before the starter can be restarted after a complete loss of power. Use this if multiple motors are connected to a supply system that may have trouble providing adequate power to restart them all at the same time. By using different Restart Delay Times on each unit, a sequential restart can be achieved.

 Note:

This is similar to the Coast Down Lockout Timer in F048, however it only activates on Power Loss.

F029 = Reserved

VMX Digital Solid State Soft Starter User Manual 44 | P a g e

5.6.7 Process Timer Control Mode (F030 through F039):

The following special functions allow the VMX Series starter to operate automatically from a Process Control Timer using an internal Real Time

Clock.

Only brief descriptions of the functions are provided here.

REFER TO APPENDIX 4 at the end of this manual for detailed

operations and instructions.

 Note:

These functions may interact with the Coast Down Lockout (F048),

Starts-per-Hour Lockout (F049), Minimum Time Between Starts

(F050), Auto-Reset (F052 and F053) and Restart Delay Time

(F028) functions if enabled. Be sure to review and understand settings for these functions before using the Process Timer.

F030 = Process Control Timer Selection

Factory Setting = 0 (Disabled)

Range = 0, 1, 2

This function enables a Process Control Timer, which may be used alone or in conjunction with the Time Clock Controller feature (F032-F039). This timer offers two operating modes, selected by entering 1 or 2 into the function parameter:

Setting 1 = Minimum (Batch) Run Timer: After a Start

Command, the starter runs until the batch timer expires. If stopped and restarted it will complete that batch time sequence.

Setting 2 = Permissive Run Timer. After a Start Event from the TCC, the starter can be started and stopped as necessary, until the timer expires.

F031 = Process Timer Value

Factory Setting = 1

Range = 1

– 9999 minutes

This function loads a value into the Process Timer above. When initialized, the value counts down towards 0.

 Note:

The above Process Control Timer in F030

– F031 works in conjunction with the Time Clock Controller in F032

– F039. When the TCC is set to One-Shot (F032 = 0), this timer will activate whenever a Start Command is given. When F032 = any other setting, this timer activates according to that schedule.

VMX Digital Solid State Soft Starter User Manual 45 | P a g e

F032 = Real Time Clock Controller

Factory Setting = 0 (One Shot)

Range = 0 - 8 settings

This function is used to select the operating mode of the 24hr /

7 Day Time Clock Controller (TCC). F032 sets the number of days in which the TCC will repeat the Start Event Cycle up to seven discrete Start Events selected in F033 through F039.

After each Start Event, the VMX Series will run per the time value set in F030 above. If F030 = 0, the TCC settings are ignored. See Appendix 4 for additional details.

1 = 1 day per week,

2 = 2 days per week

…

7 = 7 days per week

8 = A single 24HR event, non-repeating

0 = One-Shot. When set to 0, the VMX Series responds only to each Start input command. Use this setting to allow the Process

Timer to operate without the TCC (see Appendix 4 if F030=2).

F033 = Event #1 Start Time

Factory Setting = OFF

Range = 00:00 through 23:59, or OFF

This function is used to select the start time for Event #1 in the

RTCC above. Once started by this event, the VMX will run the motor according to the selections entered into F030 and F031.

F034 = Event #2 Start Time

Factory Setting = OFF

Range = 00:00 through 23:59, or OFF

This function is used to select the start time for Event #2 in the

TCC above.

F035 = Event #3 Start Time

Factory Setting = OFF

Range = 00:00 through 23:59, or OFF

This function is used to select the start time for Event #3 in the

TCC above.

F036 = Event #4 Start Time

Factory Setting = OFF

Range = 00:00 through 23:59, or OFF

This function is used to select the start time for Event #4 in the

TCC above.

F037 = Event #5Start Time

Factory Setting = OFF

Range = 00:00 through 23:59, or OFF

This function is used to select the start time for Event #5 in the

TCC above.

F038 = Event #6 Start Time

Factory Setting = OFF

Range = 00:00 through 23:59, or OFF

This function is used to select the start time for Event #6 in the

TCC above.

F039 = Event #7 Start Time

Factory Setting = OFF

Range = 00:00 through 23:59, or OFF

This function is used to select the start time for Event #7 in the

TCC above.

5.6.8 Current and Ground Fault Protection Features

F040

– F050 set extended protection features that may be used in the

VMX Series starter. Percentages shown are all based automatically upon the Motor FLA setting from F001 except Ground Fault, F046. No additional calculations are necessary.

 Note:

All of these features are disabled at the factory and must be

enabled via user programming as follows:

F040 = Current Imbalance Trip

Factory Setting = 0 (Disabled)

Range = 5 - 30% or 0 (Disabled)

Use to set the trip level for when current imbalance between any two phases exceeds this amount for the time specified

F041.

F041 = Current Imbalance Trip Delay

Factory Setting = 2 seconds

Range = 1 - 20 seconds

Provides a time delay to prevent nuisance trips from shortduration transients. Using default settings, if the difference in output current between two phases exceeds 10% of FLA for more than 2 seconds, the starter will trip.

F042 = Over Current Trip / Shear Pin Trip

Factory Setting = 0 (Disabled)

Range = 100 - 300%, 0 (Disabled)

When a value other than 0 is entered for F042, the starter will trip when the output current of any phase exceeds the amount set and the time specified in F043. This is also referred to as a

“Shear Pin Trip” and can be used to protect mechanical components from damage due to jammed loads.

F043 = Over Current Trip Delay

Factory Setting = 1 second

Range = 1 - 20 seconds

Provides a time delay to prevent nuisance trips from shortduration transients. For example using default settings, if the output current of any phase exceeds F042 for more than 1 second, the starter will trip.

F044 = Under Current Trip

Factory Setting = 0 (Disabled)

Range = 10 - 90%, or 0 (Disabled)

When a value other than 0 is entered for F044, the starter will trip when the output current of any phase drops below the amount set, and the time specified by F045. This fault condition is often referred to as a “Load Loss Trip” and can be used to detect a broken shaft, V belt or other mechanical drive system component failure. In pumping applications, this can be used as a “Loss of Prime” trip.

F045 = Under Current Trip Delay

Factory Setting = 2 seconds

Range = 1 - 60 seconds

Provides a time delay to prevent nuisance trips from shortduration transients. Using the default setting, if the output current of any phase drops below F044 for more than 2 seconds, the starter will trip.

VMX Digital Solid State Soft Starter User Manual 47 | P a g e

 5.6.8.a

Ground Fault

F046

– F047 provides Ground Fault protection for equipment only

(a.k.a. Arcing Ground Fault) using the Residual Current method.

Trip settings are based on the CT ratio as shown in F074 (see below). A delay time can be set by F047 to help prevent nuisance trips. Ground current can always be viewed in the Status Display, shown with a “G” prefix (see section 5.3.1).

WARNING!

THIS IS NOT INTENDED TO BE USED AS "PERSONNEL PROTECTION" GROUND FAULT!

This feature is only intended to provide a level of equipment protection against damaging ground currents. Ground faults are potentially dangerous conditions and must be corrected immediately for safety of operating personnel.

F046 = Ground Fault Trip

Factory Setting = 0 (Disabled)

Range = 5 - 90% of CT value, or 0 (Disabled)

When a value other than 0 is entered for F046, the starter will trip if current to ground exceeds this percentage of the unit CT value. The CT value is shown in F074 (see section 5.6.12). This value is different from the Unit Rating or FLA setting. To calculate actual ground current, multiply the CT value of F074 by the setting of F046.

Example:

210A starter, desired Ground Fault Trip level is 20A:

On this unit, the CT value reading from F074 will be 250 (250:5)

20 / 250 = 0.08 (8%).Set F046 to 8

F047 = Ground Fault Trip Delay

Factory Setting = 2 seconds

Range = 1 - 60 seconds

Provides a time delay to prevent nuisance trips from shortduration transients. Using default setting, if the Ground Fault current exceeds the level set in F046 for more than 2 seconds, the starter will trip.

CAUTION:

This method of Ground Fault sensing may not provide adequate equipment protection in resistance-grounded systems. We recommend providing external GF protection using a core balanced Zero Sequence CT for those types of applications.

Consult factory for additional assistance.

5.6.9 Lockouts, Reset and Internal Protection Features

F048

– F050 provide lockout protection for motors and equipment that may have potentially damaging consequences from premature restart or with limited duty cycles. Time and count values for these lockouts can be viewed in F055

– F058. Time values are based on the Real Time

Clock and DONOT reset when power is lost or disconnected.

Emergency clearing of lockouts can be accomplished in F071.

 Note:

When F048 through F050 are used with 3 wire control systems, a

Start command will not seal in during lockout time. When time has expired, a new Start command will be necessary.

WARNING!

When F048 through F050 are used with 2-wire control, the starter may re-start automatically when time has expired. Adequate warnings similar to those in Section

3.1.3.b should be observed.

F048 = Coast Down Lockout Timer (Back Spin Timer)

Factory Setting = 0 (Disabled)

Range = 1 - 60 minutes, or 0 (Disabled)

F048 = 1 - 60, sets the number of minutes that the starter must be off before a restart can be attempted. This function is useful in applications such as pump motor backspin protection (where you need to prevent the pump motor from restarting if it is spinning backwards), 2 speed operations where speed changes require a minimum disconnect (spin-down timer), or reversing applications to prevent plugging (anti-plugging timer).

F049 = Maximum Starts per Hour Lockout

Factory Setting = 0 (Disabled)

Range = 1 - 10 or 0 (Disabled)

F049= 1 - 10, counts the number of start commands within a 1 hour period. If the setting (maximum starts per hour) is exceeded, starting is prohibited until sufficient time has expired.

This timer initiates upon the first start in an hour. It resets after 1 hour from that start and waits until another subsequent start to initiate again. (Often used in conjunction with F050).

 Notes:

 Consult the motor manufacturer for a “Starts-per-Hour” or “Starting

Duty Cycle” rating. Larger motors tend to have lower starts-per-hour ratings.

 When using the Decel function (F025) or an electronic braking option, count these cycles as additional “starts” when determining maximum starts-per-hour.

VMX Digital Solid State Soft Starter User Manual 49 | P a g e

F050 = Minimum Time Between Starts Lockout

Factory Setting = 0 (Disabled)

Range = 1 - 60 minutes, or 0 (Disabled)

When F050 is set to 1 through 60, the motor cannot be restarted within the time specified after the first start. Time between starts is calculated from the time of the first start command to the next regardless of run time or off time.

Example:

If F050 = 15, motor will not be allowed to re-start within 15 minutes of the first start.

This function is useful as a “Short-Cycle Timer” to prevent excessive motor wear when automatic demand control may occasionally cycle on and off too quickly. e.g. compressors or sump pumps.

Internal Protection Features

The VMX Series starter contains additional protection features that are built-into the hardware and are factory preset. Function F051 is provided to alter these settings via numerical preset programming.

For maximum protection, all of these features are turned ON as a factory default and should not be changed unless necessary for service purposes, testing or to accommodate non-standard applications. Factory default settings are as follows:

 Phase Rotation: Protection is ON. The expected rotation sequence is set for A-B-C.

 Phase Current Loss (Running): Protection is ON. The unit trips at

<20% of unit Max amps after 3 seconds of acceleration and at full speed.

 Shorted SCR: Protection is ON. The unit will lock out if one SCR is shorted (no voltage drop across the SCR).

 Shunt Trip: Protection is ON. The unit trips if current flows in any phase while in the OFF mode.

 PTC Trip: Protection is ON. The unit will trip if the PTC Input resistance exceeds set value (or open).

 Line Phase Loss (Stopped): Protection is ON. The unit will trip if any phase voltage is not present while the unit is not accelerating or stopped.

F051 = Internal Protection Features

Factory Setting = 255 (all enabled)

Range = 1

– 255: Decimal value representing bit locations

F051 represents the decimal value for the binary setting of 8 bits (byte) of memory. Each of the 8 bits is set to a 1 or 0 and enables or disables the protection features depending on the setting. By adding (enable) or subtracting (disable) the decimal value associated with each of the protection features to the

F051 total allows changes to be simply made by entering the new value via the keypad. The Factory Default value is

F051 = 0255 (binary 11111111), which enables all features.

The decimal values for each feature are as follows:

VMX Digital Solid State Soft Starter User Manual 50 | P a g e

Phase Rotation Protection:

The VMX Series is set up to monitor an expected phase rotation and will trip if this changes. Control of this feature is divided into two categories: On-Off and Expected Sequence. The default setting is On, with an Expected Sequence of A-B-C.

The ability to turn this feature ON or OFF is useful in applications where the VMX Series starter is going to be used downstream from an existing reversing contactor / starter, or to avoid conflicts with other protection devices.

 Rotation Trip On-Off Control Decimal value = 1 (b 00000001)

If this feature is On (default setting) and you want to turn it Off,

Subtract 1 from F051. If this feature is Off and you want to turn it

On, add 1 to F051.When set to On, a trip will occur when the

Expected Sequence (see below) is incorrect.

On large motors where large multiple cables are used, it may be easier to change the Expected Sequence in the VMX Series starter rather than to swap the cables.

 Expected Phase Rotation Sequence Decimal Value = 2

(b 00000010

The A-B-C rotation is the default setting. To change to A-C-B, subtract 2 from F051. To change from A-C-B rotation to A-B-C, add 2 to F051.

If the Rotation Trip is set to Off (see above), this setting is ignored.

Phase Current Loss (Running) Protection:

This feature will cause a Trip if the current in any phase (or all 3) is less than 12% of the CT value after 3 seconds from a Start Command. (Note that this is based on the Max Amp rating and not the programmed FLA).

Turn it OFF if the motor no-load current is exceptionally low such as in high inertia machines, or if you are testing a large starter with a

small motor.

 Phase Loss (Running) Protection Decimal Value = 4

(b 00000100)

This feature is On (default setting). To turn it Off, Subtract 4 from F051.

If this feature is Off and you want to turn it On, add 4 to F051.

Shorted SCR Lockout protection:

This feature will cause a Lockout if at least one SCR is shorted, based on the expected voltage drop across the SCR assembly when the unit is

OFF. (Note- A shorted SCR cannot be detected while the unit is running or in Bypass mode). If qualified personnel knowing the ramifications of having a shorted SCR issue requires an emergency restart, this feature can be turned to OFF. This is not the same as a Shunt Trip circuit (see below). This is a lockout of the NEXT start command.

 Shorted SCR Lockout Decimal Value = 8 (b 00001000)

This feature is On (default setting). To turn it Off, Subtract 8 from

F051. If this feature is Off and you want to turn it On, add 8 to F051

VMX Digital Solid State Soft Starter User Manual 51 | P a g e

Shunt Trip:

Shunt Trip is a feature that will cause an immediate Trip if the VMX

Series detects current flowing through any phase (or all) while the VMX is in the Off state. The trip function is typically associated with the Aux.

Relay setting 7 (see F060-63), wired to a Shunt Trip coil in an upstream circuit breaker or an in-line contactor. This function is to interrupt power flow to the motor windings in order to prevent damage. The usual cause is multiple shorted SCRs or a welded Bypass Contactor. The only time this function should be turned off is for troubleshooting by qualified service personnel.

 Shunt Trip Decimal Value = 16 (b 00010000)

This feature is On (default setting). To turn it Off, Subtract 16 from

F051. To turn it On, add 16 to F051.

PTC Trip:

This feature controls the inclusion of the PTC Input (see Section 4.2.7).

When it is ON (default setting), a jumper wire or other circuit must be installed on the PTC input if a PTC resistor is not included in the motor.

Turn this feature to OFF for troubleshooting or if a jumper wire is not used.

 PTC Trip Decimal Value = 32 (b 00100000)

This feature is On (default setting). To turn it Off, Subtract 32 from

F051.To turn it On, add 32 to F051.

Line Phase Loss (Stopped) Trip:

This feature will prevent the VMX Series starter from attempting to start if the voltage in one (or more) of the incoming phases is not present.

This can be used to detect a blown fuse or power supply loss provided control power is still available. It differs from the Phase Loss (Running)

Trip in that it is based upon line voltage and does not require that a Start

Command be given. This trip function resets itself after determining that all 3 phases have voltage applied. The voltage level at which this feature activates is fixed at approximately 100VAC. It is not adjustable and should not be used as Under Voltage protection.

 Line Phase Loss (Stopped) Trip Decimal Value = 64

(b 01000000)

This feature is On (default setting). To turn it Off, Subtract 64 from F051.

To turn it On, add 64 to F051.

 Notes:

1) When using an In-Line Isolation Contactor, it may be necessary to turn Off this protection (by subtracting a numeric value of 64 from F051) in order to avoid nuisance tripping whenever the In-Line

Contactor opens.

2) This protection will automatically reset itself when line voltage is present on all 3 phases. When using 3-wire control, the VMX Series will not attempt to restart unless the Start Command is re-initiated.

 Caution:

When using 2-wire control, the starter will restart when this

feature resets itself after all 3 phases are present.

 Note:

To restore all settings back to the factory default, enter a value of

127. A value other than the default value of 127 indicates that one or more functions have been changed. To determine which of the protective functions have been changed/turned-off subtract the value displayed from 127 and compare the result against the

„decimal value‟ column shown in table 5.6.9.a.

Example: F051 reads a value of 109. Subtract 109 from 127 and a value of 18 remains. The value 18 does not represent a single bit value indicating that more than one function has been changed.

Referring to Table 5.6.9.a, find the largest decimal value as shown in the „decimal value‟ column smaller than 18. In this case a value of

16 (bit 4). This leaves a value of 2 (18 minus 16) which represents bit 1 (2). So in this example a value of 109 indicates that the Shunt

Trip feature had been turned off (bit 4), and the Expected Phase

Sequence had been changed to A-C-B (bit 1).

Instead of determining the previous selection add up all values in

„decimal value‟ column of the functions to be turned off and subtract this value from 127 and program the result into F051.

Communications

The VMX Series starter is shipped from the factory ready to accept

RS-485 Serial Communications using Modbus RTU protocol. Additional detailed instructions on accomplishing communications are available in a Serial Communication Supplement to this manual. F065

– F067 are used to set the communications parameters in the starter for use by the adaptor module. F068 determines how the Start / Stop functions work through the comm. port.

F065 = Communications

Factory Setting = 0 (Disabled)

Range = 0

This enables serial communications with remote monitoring and control systems and sets the format for Modbus RTU protocol.

Once Enabled, the local start / stop inputs are altered to avoid inadvertent starting. See F068 for details.

F065 = 0, communications are disabled.

F065 = 1, uses the std 11 bit Modbus format w/ parity bit.

F067 = Modbus Address

Factory Setting = 1

Range = 1

– 247

Using Modbus communications protocol, up to 247 VMX Series starters can be networked using RS485 standard communication, each having a unique address. Two devices with the same address will result in a communications error.

F068 = Remote Starter Control

Factory Setting = 0 (disabled)

Range = 0

– 3

This determines how the VMX Series starter is to be controlled when using serial communications.

When F068 = 0, the starter can be monitored by the Comm port, but not controlled.

When F068 = 1, the starter will be controlled by the comm port.

In addition, the Start / Stop inputs are altered as follows: The hardwired Start command is put in “AND” logic with the Comm port; both Start commands must be on for the VMX to start. The

Stop function is put in “OR” logic; either the Comm. port Stop command OR the hard-wired Stop will cause the VMX to stop.

When F068 = 2, the VMX starter is in full control of the Comm. port only. Local Start / Stop inputs become completely inactive.

Use this function only when controlled shutdown is a priority.

When F068 = 3, the VMX starter will change the function of the

Jog / Remote Input to cause a switch between the functions of setting 0 and setting 1 as listed above. When the input is open, the starter will respond to the Comm port as per setting F068=0 above. When the Jog / Remote Input is closed, the starter will respond as per setting F068=1 above. Use this function if it is necessary to have a return to local start/stop control should the communications system fail or become disconnected.

WARNING!

Clearing the Thermal Register to allow restarting without proper cool-down time after an

Overload Trip can result in motor damage and fire. Use only where emergency restart is

necessary with knowledge of these potential hazards.

 When F071 = 2, the values of all functions will be reset to the factory default settings. Use this feature when setting conflicts have occurred or parameters have been tampered with. The Fault History is also cleared with this function.

6.2 Start-up Check List

Supply voltage matches the rated supply voltage of the unit.

Horsepower and current ratings of the motor and starter have the same rating or the starter has a higher rating.

Initial ramp time and torque adjustments have been checked.

Input voltage source are connected to the starters input terminals

L1, L2 and L3.

Motor leads are connected to the starter output terminals T1, T2, and T3.

Appropriate control power is applied and/or control connections have been made.

“Power On” light located on the front of the unit turns on when control power is applied.

Four 7-segment LED readout is visible.

The motor‟s FLA has been programmed in function F001.

The thermal overload is properly set. (Use F003 and F004 to set OL

Class.)

The motor area and equipment are clear of personnel and parts before start-up.

6.3 Sequence of Operation

 Apply three-phase power to the unit. The motor should not run until the start command is applied.

 Apply control power and check that the “Power On” LED comes on.

 Status Display should read [0000.] showing no current in Phase A

(minor flickering of the first digit is common).

 Apply the Run (Start) command. The motor should begin to accelerate. Status display will read Phase A Amps at an increasing rate.

 When the motor reaches full speed, the “At Speed” LED comes on.

Status display should show a sharp decrease in Phase-A amps.

 If a Bypass Contactor is present (VMX…-BP model), the Bypass

Contactor should pull in.

 If the motor does not fully accelerate, decelerates, or stops during the acceleration period, push the Stop button immediately and open the disconnect line.

If Pump-Flex Decel is programmed in F025:

 Remove the Run Command (or push the Stop button). At-Speed

LED will go out.

 If a Bypass Contactor is present (VMX…-BP model), the Bypass

Contactor should drop out.

 Status display should read Phase-A amps increasing as motor begins to decelerate.

 Motor should begin to slow down. Status display should begin to show decreasing motor amps.

 When motor reaches Stop Level, starter should turn off. Status display will again show [0000.]

If the unit does not follow this operational sequence please refer to the

Service and Troubleshooting Guide section.

VMX Digital Solid State Soft Starter User Manual 63 | P a g e

6.4 Testing with a smaller motor

 To test the VMX Series starter in combination with a motor that draws less than 20% of the starters Max Amp rating, the Phase

Current Loss (Running) protection must be disabled as per instructions in section 5.6.9.a. If this feature is not disabled, the

VMX Series will trip on a Phase Loss fault after running for 3 seconds at low current levels.

Chapter 7 - Fault Conditions

Additional information on Fault Codes and possible causes can be found in the Service and Troubleshooting Guide.

7.1

Fault Codes and Numbers (in History)

A three-character fault code is displayed in the LED display at the time of the trip event. The first two digits indicate the trip condition (see Table

7.1). The third digit is a suffix showing the VMX Series operating mode when the trip occurred. Operating modes are as follows:

Code suffix “A”: Acceleration, meaning that the VMX Series was ramping up but had not yet achieved “At-Speed” status (see section

4.2.9.b for a brief description of At-Speed indication).

Code suffix “c”: Constant Speed (running), meaning that the VMX

Series has reached the At-Speed condition and the motor was running when the trip occurred.

Code suffix “d”: Decel or Stop, meaning that VMX Series was either stopped (off, but power applied), or if the Pump-Flex Decel function was enabled, it was engaged in the Soft Stop routine set up by F024-27. ???

IMPORTANT NOTE:

Fault code SSd may display if there is no output load (motor) connection when control power is applied!

In addition to these fault display codes, each trip condition has a corresponding numeric code that is stored in the Fault History (see section 5.6.13.a). The numeric codes follow the display codes exactly.

Table 7.1 shows the Fault Display Codes, Fault Number Codes and

LED indicators for each fault condition. Additional details are available in the Service and Troubleshooting Guide.

Example: If Function F003 (starting overload protection) is set too low for the size of the load and causes a trip, the fault code “oLA” will be displayed. Its corresponding number will be entered into the fault history. In this case, the number 0010 will be shown on the display in function F085 (Fault History). The time the fault occurred is available in function F086 shown as “hh.mm.” Example: if the “oLA” fault occurred at

10:00 am, F086 would display

“10.00.” The date the fault occurred is available in function F087. The date is shown as

“mm.dd”. If the “oLA” fault occurred on March 1, F077 shows

“03.01.” If no fault history is available F085 reads 0000.

Appendix 1 - Ramp Profile Details

The VMX Series offers four different types of starting ramp profiles.

Simply select the one that best matches your motor / load requirements.

In addition, two separate ramps are available that can be selected via contact closure (see section 4.2.5.a), and each one can be set up for any ramp type as shown in the table below.

Figure APP 1.2:

Voltage Ramp with Curre nt Limit

Following are descriptions of the four types of Ramp Profiles

1. Voltage Ramping is the most reliable starting method, due to the fact that at some point the starter will reach an output voltage high enough to allow the motor to draw full current and develop full torque. This method is useful for applications where the load conditions change frequently and significantly enough to require different levels of starting torque. Examples where this is effective are:

 Material handling conveyers

 Positive displacement pumps

 Drum mixers, grinders etc.

Voltage is increased from a starting point (Initial Torque) to full voltage over an adjustable time period (Ramp Time). To achieve Voltage

Ramping, set the Ramp Profile (F010) to 0001 or 0003 (Voltage Ramp), and the Maximum Current Limit setting (F014) to maximum (600%).

Since this is essentially Locked Rotor Current on most motors, there will be little or no Current Limit effect on the Ramp profile. Initial Torque setting comes from the Initial Voltage function F011.

2. Voltage Ramping with Current Limit works similar to mode 1, except this mode adds an adjustable maximum current output. Voltage is increased gradually until the motor current reaches the Maximum

Current Limit setting (F014) . The motor current is held at this level until the motor accelerates to full speed. When the motor current drops below the limit setting the output voltage is automatically increased to maximize torque until the VMX Series is At-Speed. This may be necessary in applications where the electrical power is limited.

Examples would be:

 Portable or emergency generator supplies

 Utility power near the end of a transmission line or other starting power demand restrictions.

Using Current Limit will override the Ramp Time setting if necessary, so use this feature when acceleration time is not critical. The Ramp Time setting however still determines the slope of the ramp up to the Current

Limit setting to apply the softest possible acceleration. To achieve

Voltage Ramping with Current Limit, set the Ramp Profile (F010) to

0001 or 0003 (Voltage Ramp), and the Maximum Current Limit setting

(F014) to a desired lower setting, as determined by your application requirements.

3. Closed Loop Current (Torque) Ramping provides smooth linear acceleration of output torque. Ramp Time becomes the time from Initial

Torque and Current Limit settings. Output torque is constantly updated using an internal PID feedback loop to provide a linear ramp, therefore the available torque is maximized at any given speed. The best use of this feature is for applications where rapid changes in torque may result in load damage or equipment changes. Examples would be:

 Long overland conveyors where belt stretching may occur.

 Low pressure pumps where slight surges at the end-of-ramp may pose mechanical problems.

 Fans and mixers where blade warping is a problem.

 Material handling systems where stacked products may fall over or break.

This feature can be used with or without the Maximum Current Limit setting.

To achieve Torque Ramping with the VMX Series, set the Ramp Profile

(F010) to 0002 or 0004 (Current Ramp), and the Maximum Current Limit setting (F014) to the desired level. Initial Torque setting comes from the

Initial Current function F012.

4. Current Limit Only (Current Step) uses the Current Limit feature exclusively without the benefit of soft starting by ramping the voltage or current first (also known as Pedestal Starting). This will maximize the effective application of motor torque within the limits of the motor. In this mode, Initial Torque is set to maximum and Ramp Time is set to minimum, so that the output current jumps to the Current Limit setting immediately. Examples of when to use this mode are:

 Applications with a severely limited power supply

 When starting a difficult load such as a centrifuge or deep well pump

 When the motor capacity is barely adequate without stalling or overloading.

 It is a good choice when other starting modes fail.

Since ramp times are set to minimum, this mode functions in either

Voltage Ramp or Current Ramp setting.

Ramp Parameter Descriptions

Following are detailed descriptions of the individual settings that make up each ramp profile.

Initial Torque (Initial Voltage or Initial Current).

These functions set the initial start point of either the Voltage Ramp or

Current Ramp as programmed in F010. Every load requires at least some amount of torque to start from a standstill. It is not efficient to begin ramping the motor from zero every time, since between zero and the (WK

) breakaway torque level, no useful work is being performed.

The initial torque level should be set to provide just enough torque to make the motor shaft begin to rotate, enabling the softest possible start and preventing torque shock damage to the mechanical components.

Setting this function too high will not damage the starter, but may reduce or eliminate the soft start advantages.

VMX Digital Solid State Soft Starter User Manual 67 | P a g e

Accel Ramp Time. This Function sets the maximum allowable time for ramping from the Initial Torque setting to either of the following:

1) Current limit setting when the motor is still accelerating, or

2) Full output voltage if the Current Limit is set to maximum.

Increasing the Ramp Time softens the start process by lowering the slope of increase in voltage or current. This should be set to provide the softest possible start without stalling unless it is determined that the application has other considerations. Applications where this setting should be shorter include Centrifugal Pumps, because pump problems may occur as a result of insufficient torque during acceleration through the pump curve.

 Note:

Ramp Time is affected by the following conditions:

1. Current Limit will automatically override the Ramp Time if set to

Voltage Ramp (F010=1) and if the motor does not reach full speed while in current limit mode.

An “Anti-Oscillation” circuit built-in to the VMX Series will shorten the Ramp Time if the motor reaches full speed before end of ramp.

Current Limit. This Function sets the maximum motor current that the starter allows during Ramping. It is active in both the Voltage Ramp and

Current Ramp modes. As the motor begins to ramp, this feature will set a maximum at which the current draw will be held. Current Limit will remain in effect until one of the following two events occur:

1. The motor reaches full speed as detected by the At-Speed detection circuit.

2. The Overload Protection trips on Motor Thermal Overload (see

Ch.3).

Once the motor has reached full speed, the Current Limit feature becomes inactive.

 In the Voltage Ramp Profile, the Voltage output is increased until the Current Limit is reached. The Ramp Time is the maximum time it will take for the voltage to increase until the Current Limit setting takes over. Under some load conditions, Current Limit may be reached before the Ramp Time has expired.

 In the Current Ramp Profile, output voltage varies to provide a linear increase in current up to the Current Limit setting, and Ramp

Time is the time that it will take to get there. A closed loop feedback of motor current allows continuous updating of the output to maintain this ramp profile.

Because most AC induction motors will not start below 200% current, the current limit set point is adjustable down to only 200%.

Caution:

While in the Start mode there is no maximum Current Limit time.

Excessive start time may lead to motor stalling, causing an

Overload Trip. If this happens, try raising the Current Limit setting to accommodate your load conditions. If the Current Limit setting cannot be increased, try using Current Limit without ramping

features (“Current Limit Only” as described previously).

Deceleration (Soft Stop) is a unique feature of Motortronics

Solid State Soft Starters. It provides a slow decrease in the output voltage, accomplishing a gentle decrease in motor torque during the stopping mode. This is the OPPOSITE OF BRAKING in that it will take

longer to come to a stop than if the starter were just tuned off.

Slams

The primary use of this function is with centrifugal pumps as a means to reduce the sudden changes in pre ssure that are associated with “Water

Hammer” and slamming of check valves. Decel control in pump applications is often referred to as Pump Control.

In a pump system, liquid is being pushed uphill. The force exerted by gravity on the column of liquid as it goes up hill is called the “Head

Pressure” in the system. The pump is sized to provide enough Output

Pressure to overcome the Head Pressure and move the fluid up the pipe. When the pump is turned off, the Output Pressure rapidly drops to zero and the Head Pressure takes over to send the fluid back down the hill. A “Check Valve” is used somewhere in the system to prevent this (if necessary) by only allowing the liquid to flow in one direction.

Kinetic energy in that moving fluid is suddenly trapped when the valve slams closed. Since fluids can‟t compress, that energy is transformed into a “Shock Wave” that travels through the piping system looking for an outlet in which to dissipate. The sound of that shock wave is referred to as “Water Hammer”. The energy in that shock wave can be extremely damaging to pipes, fittings, flanges, seals and mounting systems.

SOLUTION:

By using the Pump-Flex



Decel feature of the VMX Series, the pump output torque is gradually and gently reduced, which slowly reduces the pressure in the pipe. When the Pump Output Pressure is just slightly lower than the System Head Pressure, the flow slowly reverses and closes the Check Valve. By this time there is very little energy left in the moving fluid and the Shock Wave is avoided. When the output voltage to the motor is low enough to no longer be needed, the VMX Series will end the Pump-Flex



Decel cycle and turn itself off.

Caution!

Decel is THE OPPOSITE of braking. Enabling the Decel feature will make the motor take LONGER to stop than if it were simply turned off.

VMX Digital Solid State Soft Starter User Manual 69 | P a g e

Setup and Use

Pump systems vary greatly. To accommodate this, the Pump-Flex

Decel control feature is designed to provide complete flexibility in how the deceleration process takes place by using the following settings.

Decel begins when a Stop command is given (or the Run command is removed). If there is a Bypass Contactor, it will open immediately, putting the power control back to the SCRs.

When F024 = 0, the deceleration feature is disabled.

When F024 = 1, the deceleration feature is enabled AND the overload protection feature (from F003 - F005) remains active. When a

Stop command is given, the starter begins to apply Decel voltage. However, if an overload trip occurs, the starter ceases applying Decel voltage and the motor coasts to a stop to prevent additional motor heating and potential motor damage.

When F024 = 2, the deceleration feature is enabled and deceleration will continue even when an overload condition trips. This is to be used only when the risk of damage due to an uncontrolled shutdown is considered worse than the potential damage to the motor.

WARNING!

Setting F025 = 2 presents significant risk of over-heating the motor beyond its design limits which could result in motor damage and fire hazard. Do this only in circumstances where the potential for mechanical damage

outweighs the risk of motor damage and fire.

 Note:

The PTC Input will act as an Overload trip (disable), however it

ALWAYS shuts the starter down WITHOUT Decel (as in setting

F025=1 above) even if F025 is set to 2.

VMX Digital Solid State Soft Starter User Manual 70 | P a g e

F025 = Begin Decel Level (BDL)

Factory Setting = 60%

Range = 0 - 100% of line voltage

Used to drop voltage to a level where there is a noticeable effect on motor torque during Decel mode. Generally, systems with high head pressure need to start Decel near the top of the ramp (85-95%). Low head systems can drop to lower settings

(50-60%). System conditions vary greatly by pump type, pipe size and system head. Some experimentation with settings may be necessary.

F026 = Decel Shut Off Voltage

Factory Setting = 30%

Range = 0 to (BDL -1)%

Sets the level where the starter is turned off, corresponding to where motor torque during Decel is no longer effective. Always set this function lower than the setting of F026, Begin Decel

Level (this function is restricted from being less than F026 minus 1%). This function is used to shut the motor off once the check valve closes. Again, because systems vary greatly this setting may require adjustment several times. If you cannot hear or see the check valve close, observe fluid pressure or flow if available.

F027 = Decel Ramp Time

Factory Setting = 10 seconds

Range = 1 - 60 seconds

Sets the maximum time for the deceleration ramp to go from the

Begin Decel Level setting (F026) to the Decel Shut Off Voltage

(F027). This function is used to dampen the effect of reducing pump torque as much as possible. If the check valve still slams at the end of ramp, try extending this time function a little. Since motor heating increases as voltage is lowered, the setting should not exceed the time necessary to achieve the deceleration effect.

 Note:

When using the Decel function, count these cycles as additional

“starts” when determining maximum starts-per-hour.

Other Applications:

Another common application for Decel control is on material handling conveyors as a means to prevent sudden stops that may cause products to shift, fall over or to bump into one another.

In overhead crane applications, Soft Stopping of the Bridge or Trolley can prevent loads from beginning to over swing on sudden stops.

Appendix 3: Parameter Lock / User Password Instructions

Provides users with the ability to prevent unauthorized operators from making changes to the programmed functions. If you do not need to

take advantage of this feature, do not enter anything into this

function. The factory default is disabled, and no Password is necessary to make changes to the program.

When any value other than 0000 is entered into this Function, the

Parameter Lock is enabled and that number becomes the User

Password. From that point forward, it will be necessary to enter the User

Password in this Function prior to making changes in any programmed function, including this one. When the Parameter Lock has been enabled, attempts to alter the program will result in the display reading

[Err ] whenever the [READ/ENTER] key is pressed.

To alter the program after the Parameter Lock has been enabled, go to

Function F070 and enter the correct user Password. The display will read an encoded value representing the existing password. As soon as you press the first Arrow key, the display will change to [0000] and start showing the actual value of your password entry. When the [READ/

ENTER] button is pressed, the display will read [PASS], indicating that the User Password is correct and the system is unlocked. You will have

5 minutes in which to make a change in the program. This 5-minute window resets whenever any key is pressed, so it floats to give you 5 minutes after the last entry. After 5 minutes of no keypad activity, the

Parameter Lock is reinstated with the current user Password.

Subsequent changes will require re-entering the User Password.

To change the User Password or to disable the Parameter Lock function, enter the programmed User Password first, and then set

Function F070 to 0, disabling the Parameter Lock. If you do not re-enter the Password or enter a new user password, the Parameter Lock feature will remain disabled. If you enter a different number into this

Function, the new number becomes your new User Password. Existing passwords are encoded to “hide” them in the display.

Caution:

DO NOT LOSE YOUR PASSWORD.

Appendix 4: Process Control Timer Functions

F030 through F039; Overview of Process Timer Control and Time Clock Controller Features:

The following special functions allow your VMX Series starter to operate automatically from an internal Process

Control Timer and Time Clock Controller (TCC) using a real time clock. The Process Control Timer (F030 and

F031) can be used independently or together with the TCC feature (F032-39). The TCC requires using the

Process Control Timer to provide for Start commands (depending on the selected mode). Time progression and clock values can be read in the Status Screen (see section 5.3.1).

A convenient chart at the end of this appendix shows all settings and interactions.

In this mode, the Process Control Timer ensures that the motor will run for a minimum amount of time, regardless of whether someone stops it intentionally, or power fails and returns. When selected, the Minimum Run Timer begins counting down after a Start command. The Time Value is set in

F031. When the time value reaches [0000] the starter will turn off, even if the Start command is still closed and there is no

Stop command.

To Reset the timer in this mode, initiate a Stop command after the timer has expired. If using the TCC (F032), reset is automatic when completed and no there is no other Run command is present.

If a Stop Command, power failure or Fault trip occurs during timed operation, the Process Control Timer is suspended and maintains its value. When the starter is then restarted, the timer resumes counting down to ensure that the motor has run for the programmed amount of time (finishes the batch).

Use this function to ensure that a load operates for a minimum amount of time regardless of other circumstances. Examples would be:

 Irrigation pumps where a specific amount of pumping time is required even if the pump is shut down on a low level alarm and then resets, or power fails and returns.

 Mixers that need to agitate for a specific amount of time yet may be shut down when power fails or as product is added.

 Aeration Blowers that must be run for minimum amounts of time to ensure that proper aeration (contact time) has been provided to a tank.

 Note:

In 2-wire control systems where the Run command is maintained, the starter will automatically restart after a power failure or a Fault is reset.

Use appropriate warnings as mentioned in section 3.1.3.b (see the following F032 description for an exception to this).

In 3-wire control systems, a new Start command will be required to restart the starter.

VMX Digital Solid State Soft Starter User Manual 74 | P a g e

Example: Figure App 4.1

Minimum Run (Batch) Timer

An irrigation pump needs to come on when called for by a soil moisture control system, and run for ½ hour. If during that ½ hour the well level drops and shuts the pump down, the pump needs to restart when the well recovers and finish the ½ hour pump time.

Set F030 to [0001] for Minimum Run Timer.

This will ensure that when the well level recovers and resets the run command, the starter will finish the time sequence.

Set F031 to [0030] (minutes)

This is the Run Time that ensures the proper amount of irrigation getting to the crop.

(Not Shown)

Ensure F032 is set to [0000] for One Shot

This will allow the Start command provided by the external control system to engage the starter at any time it is required.

Controller is provided further on)

Program m ing the Minim um Run Tim er Functions

 Notes on interactions with other functions:

When used with F028 (Auto-Restart Delay), the Minimum Batch

Timer will not resume counting down until F028 has expired and the starter has restarted. When used with 3 wire control, it may be necessary to maintain a Start Command until after F028 has expired, or repeat if momentary.

When used with F049

– F050 (Lockout Protection features), the

Minimum Batch Timer will not resume counting down until those settings have been satisfied and the VMX Series starter has restarted. When used with 3-wire control, it may be necessary to maintain a Start Command until after they are satisfied, or repeat if momentary.

When used with the Pump Flex Decel feature, the Decel Time

(F027) is counted as part of the Batch Run time for this feature.

VMX Digital Solid State Soft Starter User Manual 75 | P a g e

F030 = 2: Permissive Run Timer.

In this mode, the Process Control Timer engages differently according to the settings of the Time Clock Controller (TCC).

When the TCC is set to 0

(using “One Shot” operation), the

Process Control Timer begins counting down after the first Start command. Subsequent stop and start commands have no further affect on the timer status and can be used to fully control the starter. When the timer finishes (F031 = [0000]), the starter will shut off. Upon the next Start command, the timer will reset and begin counting down again. In 2 wire control systems, the starter will shut off even if the Run command is still closed, and will only reset after the Run command has been cycled (opened and reclosed).

Use this function in without the Time Clock Controller (One-Shot mode) to ensure that a load only operates for a maximum of the programmed amount of time, beginning with the first Start command. Examples would be:

 Pumps where the failure of a stop float may lead to dry run conditions if allowed to operate too long, or when the pump only needs to run when someone is present, but operate automatically via float switched (pump-out for service).

 Ventilation Blowers where operation is controlled by a manual switch but may be inadvertently left on when someone leaves.

When the TCC is set for 1 through 8 (using Start Event Cycles), the timer begins counting down immediately when a Start

Event is activated. Any Start / Stop Command that is given to the starter during this time will work normally. When the timer finishes (F031 = [0000]), the starter will shut off, and Start /

Stop commands will no longer function until the next Start

Event Cycle (SEC). In 2 wire control systems, If a Run command is already present when the SEC occurs, it will make no difference and the starter will start.

Reset of the Permissive Run Timer will occur only when the next Start Event Cycle is activated by the Time Clock Controller, or when changes are made to programming (see note on programming changes (see “Important Note” on page 80). Loss of control power without program changes will NOT reset the time.

Use this function in conjunction with the Time Clock Controller to ensure that a load only operates during the programmed amount of time, beginning with the Start Event Cycle. Examples would be:

 Air compressors where leaking of air lines during normal downtime causes the compressor to run unnecessarily

 Irrigation pumps where operation during parts of the day is undesirable.

 Energy Savings to prevent operation when Time-of-Use (TOU) metering discounts are provided to promote conservation.

VMX Digital Solid State Soft Starter User Manual 76 | P a g e

Example: Figure App 4.2

Permissive Run Timer

An air compressor controlled by a pressure switch feeds a large air distribution system that has small normally insignificant leaks.

If left on over night when the system is not in use, leaks drop the air pressure and the compressor cycles on and off even though the facility is unoccupied, wasting energy.

Set F030 to [0002] for Permissive Run Timer.

This will ensure that if not purposely turned off, the compressor will not run when the facility is shut down.

Set F031 to [0600] minutes (10 hours)

This is the longest Run Time after which the starter will automatically shut down. This ensures that it will not restart after the time expires and until a new Start Event occurs.

(Not Shown)

Ensure F032 is set to [0001] for Every Day, and F033 is set to

correspond to work start time (or 5 minutes prior)

This will allow the Run command provided by the pressure switch to engage the starter any time it is required after the shift begins.

With this setting, the compressor will start whenever the pressure switch calls for it after the Start Event set by the Time Clock

Controller, but if forgotten, it will shut itself off after 10 hours. If power is turned off or lost during those 10 hours, the timer is not cleared or reset, so even if it is turn back on 1 minute before the timer expires, it still shuts off at the end of that 10 hour period.

Notes:

If the

Process Control Timer

(F030) is set for Minimum Batch Timer (value of 1), and the next

Start Event Cycle passes without a Start command, the previous event will be ignored in favor of the new one.

If a

Process Control Timer

setting from F031 is so long that it overlaps a Start Event Cycle setting in F032-F039, the original timer value becomes invalid. The new Start Event Cycle reloads the value of F031 and begins counting down again from the beginning.

F031 = Process Timer Value

Factory Setting = 1

Range = 1

– 9999 minutes

This function loads a value into the Process Control Timer above. When initialized, the value counts down towards 0.

F030 sets the operating mode and reset functions for this timer.

The value of this timer can be read directly in the main Status

Screen (see section 5.3.1). When the Process Control Timer has been enabled in F030, the Status Screen display for the value will flash once per second while timing. When completed, it will stop flashing and read [0000].

VMX Digital Solid State Soft Starter User Manual 77 | P a g e



IMPORTANT NOTE: When F030 or F031 is changed in program mode, the timer

will not respond to the new settings until after control power has been cycled (off

and back on again).

F032 = Time Clock Controller (TCC)

Factory Setting = 0 (One Shot)

Range = 1 - 8 settings

This function is used to select the operating mode of the 24hr /

7 Day Time Clock Controller (TCC).

F032 = 0 operates the SEC in a “One-Shot” mode (factory default setting). When set to 0, the Process Timer (F030) responds only to each NEW hard-wired START input command.

Use this setting to allow the Process Control Timer to operate without the TCC.

For safety purposes when using 2 wire control systems in this mode only, if power fails and the START/RUN command is present when power is restored, the starter will ignore this command until the input is cycled Off and back On (terminals

TB1-1 and 3 are opened and reclosed).

For automatic operations, F032 can also set the number of days in which the TCC will repeat a Start Event Cycle (SEC).

Each Start Event Cycle consists of from 1 to 7 Start Events as programmed in F033 through F039 below. Start Events can be non-sequential (see Note below).

F032 = 1 operates the SEC every day of the week.

F032 = 2 operates the SEC every 2 days (every other day)

F032 = 3 operates the SEC every 3 rd

day.

F032 = 4 operates the SEC every 4 th

F032 = 5 operates the SEC every 5 th

day.

F032 = 6 operates the SEC every 6 th

day.

day

F032 = 7 operates the SEC 1 day per week.

F032 = 8 operates the SEC for a single 24HR event, nonrepeating. Use this for testing or for “walk away” operations that need to run after you leave but not again.

Start Event Cycles allow the use of a Start Command (2-wire or

3-wire) ONLY AFTER the time of the Start Event has passed

(logic state AND). In a 3-wire control system, this is similar to having an Enable switch in series with the Stop button. In a 2wire control system, this is similar to having and Enable contacts in series with the Run contact. The Stop Button (or opening the Run contact) will always work to shut down the

VMX Series starter. If F032 is set to anything other that 0, the normal Start

– Stop functions will not longer work except as shown above.

Each Start Event is a timed operation based on the Process

Timer settings in F030 above.

Important:

If F030 = 0 (Disabled), the TCC will be ignored. So if F032 = 1-8 and F030 = 0, the starter will not operate!

Make sure that if F030 = 0, F032 = 0 as well.

Time Clock Controller with Minimum Run Timer

An irrigation pump fed from a well with a single float level control needs to come on every other day at 5:30 PM, and run for ½ hour.

If during that ½ hour the well level drops and shuts the pump down, the pump needs to restart when the well recovers and finish the ½ hour pump time.

Set F030 to [0001] for Minimum Run Timer.

This will ensure that when the well level recovers and resets the run command, the starter will finish the time sequence.

Set F031 to [0030] (minutes)

This is the Batch Time that ensures the proper amount of irrigation getting to the crop.

Set F032 to [0002] for Every 2 nd

Day

This will begin the Start Even Cycle on the day of programming and every other day from then on.

Set F033 to [17.30]

This is the 24HR time value representing 5:30 PM. At this time, every other day, the VMX Series starter will automatically start

(provided the Stop float in the well is closed) and run for 30 minutes as programmed in F030.

If the pump needs to come on again at 7:00 PM, program F034 to

[19.00]. If later on it is needed to come on at 6:00 AM as well, simply change any other unused start time, i.e. F038 to [06.00].

Even though this is Event #6 and the lower numbered events had later start times in the program, the starter will execute #6 on time in the next available cycle.

If the pump needs to come on every day, program F032 to [0001].

Appendix 5 – External Over Load Relay Applications

Your VMX Series starter comes equipped with a very intelligent internal electronic overload protection system, and does not need an external

Over Load Relay (OLR). There are instances however where external

OLRs are needed or desired because of the application. These fall into three categories; Higher Level Protection systems, Redundant Backup applications and Special Motor applications.

 Note:

If the Decel Function is activated (F024), additional consideration must be put into determining how the starter is to operate in the event of an Over Load Trip. See Section 5.6.5 for issues regarding this application.

HIGHER LEVEL PROTECTION SYSTEMS

Because of a desire for uniformity and/or operator familiarity in some facilities, Motor Protection Relays or other coordinated OEM protection systems may be used in lieu of the VMX Series protection (even though most of the features are the same or better). In these instances the

VMX Series Over Load protection can simply be turned off, deferring protection to the external devices. Care should be taken however to ensure that the external device is properly wired into the starter control circuit to facilitate shutdown of the motor. The VMX Series provides a

PTC input that can be wired to the NC aux contact of the external device so that a fault will still shut down the VMX Series and be annunciated on the display. See section 4.7.2.a for more details on using the PTC input.

REDUNDANT BYPASS STARTER APPLICATIONS:

In some applications, it may be necessary to provide an independent means of starting and protecting the motor should be VMX Series starter become inoperable. If this were the case, the Bypass Contactor could be used for Across-the-Line (D.O.L) starting of the motor. The

VMX…BP version with Integral Bypass Contactors is designed for that possibility, as long as the starter is properly selected when ordered. To do so, select the starter based upon the ATL (Across-the-Line) selection chart so that the contactor is rated for ATL duty instead of the normal

Shunt Duty (see section 1.2.3 for Selection charts).

Under normal operations, the Bypass Contactor is controlled internally by the VMX Series PC board and an internal pilot relay. For redundant backup purposes however, terminals B1 and B2 of TB4 are provided for field connection of a dry contact closure in parallel to the pilot relay contact, allowing control even if the electronics are out of service. AC control power must still be applied to TB2 terminals A1 and A2, but no other electronics or power supplies need to be functioning. It is in this instance that an external OLR must be added to the motor power circuit and wired into that coil control circuit. TB4 is located in different areas of each frame size in the VMX Series. Refer to the following diagram for the location on your unit.

Figure APP5.2: VMX Wiring for Across-the-Line Bypass Operation with External Overload Relay

(Only the terminals necessary for this operation are shown)

In this example:

The Start / Run command (2-wire or 3-wire) energizes a control Relay

“CR”. If the selector Switch is in the “SS” (Soft Start) position, the contact of CR closes the 24VDC control signal to TB1, terminals 1 and 3 of the VMX Series, which begins ramping. When At-Speed status is reached, an internal Bypass Pilot Relay is used to close the Bypass

Contactor. While in this mode, the VMX Series CPU provides full motor protection, even when the Bypass Contactor closes.

When the Selector Switch is placed in the “A-T-L” (Across-the-Line) position, a 2 nd

isolated contact of CR is used to close the circuit between

B1 and B2 of TB4 which are internally connected in parallel to the

Bypass Pilot Relay contact in the Bypass Contactor coil circuit. Since the VMX Series electronics may be out of service, an External Overload is added which only operates in this mode and protects the motor by dropping out the connection between B1 and B2.

Caution:

The circuit on TB-4 is at the same potential as the AC control voltage, but should not be

directly connected to it. PC board damage may result.

Appendix 5 (cont.) External OL Relay Applications

SPECIAL MOTOR APPLICATIONS

Multiple Motors

When more than one motor is connected downstream from the VMX

Series starter, the internal electronic overload protection cannot provide proper protection of the individual motors. Codes require the use of separate OLRs for each motor, which would need to be external devices.

In these instances the VMX Series Over Load protection should be turned off, deferring protection to the separate OLRs. Care should be taken to ensure that the External OLR is properly wired into the starter control circuit to facilitate shutdown of the motor. The VMX Series provides a PTC input that can be wired to the NC auxiliary contact of the external OLR so that a trip will still shut down the VMX Series and be annunciated on the display. Multiple OLRs would then be wired in series for the same effect. See section 4.7.2.a for details on using the PTC input.

Warranty information.

1 Year Warranty:

Phasetronics Inc., dba Motortronics, (hereinafter “Company”) warrants the VMX Series products to be free from defects in material and/or workmanship for a period of one (1) year from the date of sale, or a maximum of 18 months from the date of manufacture (if no sales records are available) as indicated by the unit‟s date code. The Company reserves the right to repair or replace any malfunctioning units or sub assemblies under warranty at the Company‟ sole option. Warranty repairs may be performed at the Company‟s facility, in the field by a factory-authorized technician, or by the customer only with prior approval and at the specific direction of the

Company‟s Technical Services personnel. During the 1 year period, malfunctions of the control boards will be dealt with by replacement of the Modular Control Assembly (MCA), which contains the

User Interface Panel, Digital Control Unit, Bypass control (if any) and Communications Interface. The MCA is designed to be replaced quickly without the need for tools (plug-in), and as such will constitute the majority of warranty replacements.

Warranty Service Procedure:

In the event that warranty service becomes necessary, contact the distributor where the starter was purchased, or Motortronics Technical Services department directly at (727) 573-1819. Be prepared to provide the complete

Model number, Serial Number, date and place of purchase. It is also helpful to know the date of initial commissioning. When Technical Services has determined the nature of the problem and that sending replacement parts or assemblies can repair it, they will require a purchase order for replacement parts and issue a Return Material Authorization (RMA) for the defective parts or assemblies. If any components or assemblies are received at the factory without the proper RMA documentation, the shipment(s) will be refused.

When the replacement parts are received and evaluated at the factory, any warranty determination will result in an offsetting credit being issued for the replacement parts already sent out. If the unit is not needed for immediate operation, an alternative is to have the Technical Services representative provide an RMA for the components, and they will be evaluated and repaired at the factory, and returned. In either circumstance, freight/shipping costs are the responsibility of the purchaser.

Responsibility:

Company is not responsible for the misuse or misapplication of its products, intentional or otherwise. Improper application, installation, failure to provide safety devices or protective measures, or operation above its ratings, and failure to properly maintain or service products are all beyond the control and responsibility of the Company.

Under no circumstances shall the Company be liable for loss of profits, indirect, incidental, special, consequential or other similar damages arising out of the misuse, misapplication or failure to maintain the Company‟s products.

SCR power devices used in the VMX Series (and all other solid state motor control products) are covered under warranty only when it has been determined by the Company that a failure of another system within the MCA or firing board circuit has directly caused damage to the SCRs. Although every effort is provided to prevent SCR damage, it can still occur as a result of circumstances beyond the control of the Company. Improper starting conditions such as under sizing, rapid duty cycling and improper settings, or external power problems such as lightning strikes, capacitor switching, shorted motor windings or locked rotor currents can all cause damage to

SCRs under the wrong circumstances. Failures under those conditions are not covered under warranty.
