Product Description 1.1

1.1.1 GENERAL

This instrument is a microprocessor based single loop controller capable of measuring, displaying and controlling temperature, pressure, flow, and level from a variety of inputs.

Control functions, alarm settings and other parameters are easily entered through the front keypad. All user's data can be protected from unauthorized changes with it’s ENABLE MODE security system. Battery back-up protects against data loss during AC power outages.

The input is user configurable to directly connect to either thermocouple, RTD, mVDC, VDC or mADC inputs. Thermocouple and RTD linearization, as well as thermocouple cold junction compensation is performed automatically. The sensor input is isolated . The instrument can operate on either 115VAC or 230VAC power at 50/60Hz. It is housed in an extruded aluminum enclosure suitable for panel mounting. It may be surface mounted using an optional adaptor.

1.1.3 CONTROL

The instrument can be programmed for on-off, time proportioning, current proportioning, or position proportioning control implementations depending on the model number. A second control output is an available option. Proportional control implementations are provided with fully programmable separate PID parameters.

1.1.4 ALARM

Alarm indication is standard on all instruments. Alarm type may be set as PROCESS DIRECT or REVERSE (High or Low), DEVIATION DIRECT or REVERSE (Above or Below setpoint), or

DEVIATION BAND TYPE (Closed or Open within the band). Alarm status is indicated by

LED. An alarm output can be provided by assigning any output(s) SPST relay(s) or SSR

Driver(s) to the alarm.

1.1.5 EXTENDED FEATURES SOFTWARE

EA Software Features

Fast Scan Provides an optional faster scan rate of 3 scans per second.

Normal scan is one scan per second.

Process Rounding Provides rounding of the process value displayed to reduce display fluctuation. For example, the displayed value can be rounded to the nearest 5 (display -5, 0, 5, 10, etc.). This is for display only and does not affect the control action.

Relay Actuation

The current outputs available can be extended to include 0-20mA and 0-5VDC (with the appropriate shunt resistor), rather than the standard 4-20mA and 1-5VDC outputs.

The process or setpoint value can be scaled over any desired range and retransmitted using one of the current outputs. (This precludes the use of the output for control).

Provides a relay actuation based upon a proportional output being above or below a specified value.

Contact Closure Sensing This feature provides the following action: When a contact closure for SP=PV is sensed, the setpoint will be set equal to the current process value. This is only done on the transition from open to closed, and not continuously while the switch is closed.

EB Software Features

Setpoint Ramp Provides a limitation on how fast the process value will ramp to setpoint by

Rate limiting the rate of change of an internal setpoint used for control versus the setpoint the operator specifies.

Installation and Wiring 2.1

Prior to proceeding with installation, verify the AC power input required by the instrument. AC power input is either 115 VAC or 230 VAC and is specified in the model number and on the wiring label affixed to the instrument housing. See Figure 2-4 (page 13) for a wiring label description.

230 VAC models may be converted to 115 VAC operation by the user, by changing the position of jumpers soldered on the Power Supply Board, see Appendix A-1 (page 59) for details.

Electrical code requirements and safety standards should be observed and installation performed by qualified personnel.

The electronic components of the instrument may be removed from the housing during installation. To remove the components, loosen the locking screw located in the lower center of the instrument’s front panel. Pull the entire instrument straight out of the housing. During re-installation, the vertically mounted circuit boards should be properly aligned in the housing. Be sure that the instrument is installed in the original housing. This can be verified by matching the serial number on the unit to the serial number on the housing.

(Serial numbers are located on the inside of the housing enclosure and on the label on the underside of the front panel) . This will insure that each instrument is accurate to its published specifications. The ambient compensator on the rear of the housing enclosure is calibrated to the electronics of the instrument at the factory.

Recommended panel opening sizes are illustrated below (Figure 2-1). After the opening is properly cut, insert the instrument housing into the panel opening. Insert the two panhead screws provided, through the holes in the mounting bracket into the holes in the rear of the instrument as shown in Figure 2-1. Firmly tighten the screws. Instruments are shipped standard for panel mounting. To surface mount, an adaptor is required and should be specified when ordering. For installation in wash-down areas, a watertight cover is available.

Preparation for Wiring 2.2

2.2.1 WIRING GUIDELINES

Electrical noise is a phenomenon typical of industrial environments. The following are guidelines that must be followed to minimize the effect of noise upon any instrumentation.

2.2.1.1 INSTALLATION CONSIDERATIONS

Listed below are some of the common sources of electrical noise in the industrial environment:

• Ignition Transformers

• Arc Welders

• Mechanical contact relay(s)

* Solenoids

Before using any instrument near the devices listed, the instructions below should be followed:

1. If the instrument is to be mounted in the same panel as any of the listed devices, separate

them by the largest distance possible. For maximum electrical noise reduction, the noise

generating devices should be mounted in a separate enclosure.

2. If possible, eliminate mechanical contact relay(s) and replace with solid state relays. If a

mechanical relay being powered by an instrument output device cannot be replaced, a

solid state relay can be used to isolate the instrument.

3. A separate isolation transformer to feed only instrumentation should be considered. The

transformer can isolate the instrument from noise found on the AC power input.

4. If the instrument is being installed on existing equipment, the wiring in the area should be

checked to insure that good wiring practices have been followed.

2.2.1.2 AC POWER WIRING

Earth Ground

The instrument includes noise suppression components that require an earth ground connection to function. To verify that a good earth ground is being attached, make a resistance check from the instrument chassis to the nearest metal water pipe or proven earth ground.

This reading should not exceed 100 ohms. Use a 12 gauge (or heavier) insulated stranded wire.

Neutral (For 115VAC)

It is good practice to assure that the AC neutral is at or near ground potential. To verify this, a voltmeter check between neutral and ground should be done. On the AC range, the reading should not be more than 50 millivolts. If it is greater than this amount, the secondary of this

AC transformer supplying the instrument should be checked by an electrician. A proper neutral will help ensure maximum performance from the instrument.

2.2.1.3 WIRE ISOLATION

Four voltage levels of input and output wiring may be used with the unit:

• Analog input or output (i.e. thermocouple, RTD, VDC, mVDC or mADC)

• SPST Relays

• SSR driver outputs

• AC power

The only wires that should be run together are those of the same category. If they need to be run parallel with any of the other lines, maintain a minimum 6 inch space between the wires.

If wires must cross each other, do so at 90 degrees. This will minimize the contact with each other and reduces "cross talk" "Cross talk" is due to the EMF (electro Magnetic Flux) emitted by a wire as current passes through it. This EMF can be picked up by other wires running in the same bundle or conduit.

In applications where a High Voltage Transformer is used, (i.e. ignition systems) the secondary of the transformer should be isolated from all other cables.

This instrument has been designed to operate in noisy environments, however, in some cases even with proper wiring it may be necessary to suppress the noise at its source.

2.2.1.4 USE OF SHIELDED CABLE

Shielded cable helps eliminate electrical noise being induced on the wires. All analog signals should be run with shielded cable. Connection lead length should be kept as short as possible, keeping the wires protected by the shielding. The shield should be grounded at one end only. The preferred grounding location is the sensor, transmitter or transducer.

2.2.1.5 NOISE SUPPRESSION AT THE SOURCE

Usually when good wiring practices are followed no further noise protection is necessary.

Sometimes in severe electrical environments, the amount of noise is so great that it has to be suppressed at the source. Many manufacturers of relays, contactors, etc. supply "surge suppressors" which mount on the noise source.

For those devices that do not have surge suppressors supplied, RC (resistance-capacitance) networks and/or MOV (metal oxide varistors) may be added.

Inductive Coils - MOV's are recommended for transient suppression in inductive coils connected in parallel and as close a possible to the coil. See Figure 2-2. Additional protection may be provided by adding an RC network across the MOV.

Contacts - Arcing may occur across contacts when the contact opens and closes. This results in electrical noise as well as damage to the contacts. Connecting a RC network properly sized can eliminate this arc.

For circuits up to 3 amps, a combination of a 47 ohm resistor and 0.1 microfarad capacitor

(1000 volts) is recommended. For circuits from 3 to 5 amps, connect 2 of these in parallel.

See Figure 2-3.

2.2.2 SENSOR PLACEMENT (Thermocouple or RTD)

Two wire RTD's should be used only with lead lengths less than 10 feet.

If the temperature probe is to be subjected to corrosive or abrasive conditions, it should be protected by the appropriate thermowell. The probe should be positioned to reflect true process temperature:

In liquid media - the most agitated area.

In air - the best circulated area

THERMOCOUPLE LEAD RESISTANCE

Thermocouple lead length can affect instrument since the size (gauge) and the length of the wire affect lead resistance.

To determine the temperature error resulting from the lead length resistance, use the following equation:

Terr = TLe * L where; TLe = value from appropriate table below

L = length of leadwire in thousands of feet.

Configuration and Operation 3.1

3.1.1 POWER UP PROCEDURE

Verify all electrical connections have been properly made before applying power to the instrument.

If the instrument is being configured (set up) for the first time, it may be desirable to disconnect the controller output connections. The instrument will go into the Control mode following the power up sequence and the output(s) may turn on. During power up, the seven digit model number will be displayed. Next, the software revision level will be displayed, followed by the EPROM tab number. Instrument self test 1 through 3 will take place as they are displayed. After completion of the tests Ctrl will be displayed for 3 seconds. At this time another mode of operation may be selected by pressing the SCROLL key.

3.1.2 CONFIGURATION PROCEDURE

Parameter selections and data entry are made via the front keypad. To ease configuration and operation, the user selectable features have been divided into several sections (modes).

Data and parameter entries are made by stepping through each mode and making an appropriate response or entry to each step as necessary for the application.

Configuration Summary 3.3

All configurable parameters are provided in Tables 3-1 thru 3-3 on the following pages. These tables illustrate the display sequence, parameter adjustment and factory setting for each step.

The instrument is provided with a “time-out” feature. If the instrument is in any mode, other than the Control mode, and no keypad activity takes place for 30 seconds, the mode will be exited automatically. The instrument will then display the code for the respective mode. If a mode code is displayed for five seconds with no key stroke activity the “time-out” will cause the instrument to return to the Control mode of operation.

3.3.1 ENABLE MODE CONFIGURATION

The Enable Mode provides a means of enabling or disabling access to setpoint changes and each of the non-control modes. In the Enable mode, each mode except Control, will be displayed. Either “on” (enabled) or “oFF” (disabled) may be selected. See Table 3-1 (below) for the Enable mode procedure. For additional security, the Enable mode may be locked out by using a hardware jumper, JU 2, located on the Processor board. See Appendix A-2

(page 59).

3.3.2 PROGRAM MODE CONFIGURATION

The Program mode is used to configure or re-configure the instrument. All possible parameters are illustrated in Table 3-2 (page 28) for illustrative purposes. Only those parameters that are applicable to the hardware options chosen or to previous parameter selections will be displayed.

3.3.3 TUNE MODE CONFIGURATION

The Tune mode is used to adjust the tuning parameters and the alarm setting needed for operation of the instrument.

TABLE 3-1 ENABLE MODE CONFIGURATION PROCEDURE

To enter the Enable mode depress and hold the UP and DOWN keys. All display lamps will light, after ten seconds the display will read EnAb. If EnAb does not appear, check the position of the Enable mode jumper, JU 2, located on the Processor board (See Appendix A-

2, page 60). Release the keys and the display will then change to EtSt.

Depress the SCROLL key to review the state (on or off) of the mode. Use the UP key to enable a mode that is off. Use the DOWN key to disable a mode that is on. When all selections have been made, to exit the Enable mode depress the UP key with a mode code displayed EtSt, ECAL, etc.

Tune Mode Operation 3.4

Proportional output control may require the adjustment (tuning) of the PID and other related parameters. This provides a means for the instrument's control algorithm to be adjusted to meet specific application requirements.

3.4.1 SYSTEMATIC TUNING METHOD

1. Changes in tuning parameters should be made one at a time.

2. After making any changes in tuning parameters, a disturbance should be introduced into

the process so that the process reaction may be observed. This process reaction, or

recovery, will tell whether the tuning parameters provide the desired control. It is usually

easiest to make a step change in setpoint to introduce this disturbance.

3. The change in setpoint, or disturbance, referenced above should be large enough to cause

an observable deviation of process from setpoint. However, this change should not be so

large that it will cause the controller output to proceed to either extreme limit.

4. Controller tuning for optimal control is not hard and fast, BE PATIENT. The process will

take a certian amount of time to react to the setpoint changes during tuning. The amount

of time depends upon the specific process, however, a period of 8 to 12 minutes should be

allowed between changes. The important point to remember is to allow the process to

react completely, do not rush through tuning of the controller. If the complete process

reaction is not observed, optimum control may never be achieved.

5. Time Proportioning control output(s) require(s) the cycle time to be adjusted for the

application. Short cycle times typically result in the most accurate process control, but will

cause the quickest wear out of any mechanical components.

6. Leave all other tuning parameters (except for the alarm settings, if used) at the factory

default settings. Obtain the best possible process reaction by adjusting the Proportional

Bandwidth parameter. The setting that achieves the best response for the process should

be left in the controller programming, and should be noted on the Software Reference

Sheet in Appendix E (page 70).

7. If there are to be no setpoint or load changes in the process, the Proportional Band

adjustment may be all that is necessary for proper control. If an offset still exists (the

process does not settle out at setpoint with the best possible proportional band adjustment)

Manual Reset may be added to eliminate this offset.

8. Auto Reset may be added to eliminate offsets and improve response to setpoint and load

changes. Increase Auto Reset from 0 to 0.2 increments. Start with a small amount.

Increase this increment if there is no apparent reaction. Remember to allow the process 8

to 12 minutes to react.

9. If necessary, Rate may be added. Rate is a dynamic tuning parameter. Rate may be

required to compensate for process lags or to help inhibit reset windup when a large

amount of Auto Reset (4 or 5 repeats per minute) is being used.

10. Controller tuning is not hard and fast. It may be necessary to adjust the tuning

parameters over a period of time to obtain optimal control of the process.

3.4.2 ZIEGLER NICHOLS TUNING METHOD

This procedure has been determined empirically to yield 1/4 amptitude decay tuning parameters that are determined by watching the system in a sustained oscillation (curve C, page 36, the ultimate proportional band and ultimate time period) and then using these values from this sustained oscillation to calculate ideal parameters.

Determining Ultimate Proportional Band and Ultimate Time Period

1. Set Manual Reset rSet to 0.0, set ArSt to 0.0 and set rAtE to 0.0

2. Enter the Control mode of operation, observe the process reaction.

3. Set the Proportional Band (PB) at 100 and upset the process and observe the

response. One easy method for imposing the upset is to move the setpoint for a

few seconds and then return it to its original value.

4. Achieve a response curve similair to the sustained oscilaltion (curve C), this is the

Ultimate Proportional Band (UPB) and Ultimate Time Period (UTP).

a) If the response curve from step 3 does not damp out, as in Curve A from

the drawing, the PB is too low. The PB should be increased and step 3

repeated.

b) If the response in step 3 damps out, the PB is too high. The PB should

be decreased and step 3 repeated.

These values obtained for Ultimate Proportional Band (UPB) and Ultimate Time Period (UTP) are used to calculate ideal P, PI, PD, PID tuning parameters using the following Ziegler-

Nichols equations:

Proporational only control (P) -

P (Pb) = 2 x UPB (degrees or units)

Proportional plus automatic reset (PI)

P (Pb) = 2.2 x UPB (degrees or units)

I (ArSt) = 1.2 / UTP (repeats per minute)

Proportional plus derivative (or rate) (PD) -

P (Pb) = 1.7 x UPB (degrees or units)

D (rAtE) = UTP / 8 (minutes)

Proportional plus automatic reset plus derivative (PID)

P (Pb) = 1.7 x UPB (degrees or units)

I (ArSt) = 2 / UTP (repeats per minute)

D (rAtE) = UTP / 8 (minutes)

If an overdamped response is desired, multiply the proportional band by two.

Control Capability 4.1

A variety of user programmable control features and capabilities are available including:

• On-Off Control

• Current Proportioning

• Alarm Functions

• Auto/Manual Switching

• Setpoint Adjustment

• Time Proportioning Control

• Position Proportioning Control

• Dual Output Control

• Automatic Transfer

• Process Re-transmission

The capabilities available in a specific unit are dependent upon the hardware options specified when the instrument is ordered. Refer to Appendix C (page 61) for the decoding of the instrument model number. Current proportioning control cannot be implemented if a current output was not ordered. Position proportioning cannot be implemented if two relays (Outputs

1 and 2) and the option have not been ordered. The available output types and quantity of each are as follows:

Type of Output

* SPST mechanical relay output

* SSR Driver

* mADC current output

Quantity Available

Up to three

Up to three

Up to two

The maximum number of SPST relay and/or SSR driver outputs available on a single instrument is three. Relay and SSR drivers may be assigned as either control or alarm outputs.

The mADC current output(s) may be assigned control or process value retransmission output functions.

Control Responses 4.2

Each instrument may be configured to provide 3 mode proportional control. Proportional control is provided with Proportional Band, Integration, and Derivative responses.

Manual Reset is provided for use in lieu of, or in conjunction with automatic reset. A cycle time adjustment parameter is provided for use with each time proportioning control output.

Direct/Reverse

Operation of Outputs 4.3

Direct operation is typically used with cooling applications. On-Off direct output(s) will turn on when the process variable exceeds setpoint. Proportional direct output(s) will increase the percentage of output as the process value increases within the proportional band.

Reverse operation is typically used with heating applications. On-Off reverse output(s) will turn off when the process variable exceeds setpoint. Proportional reverse output(s) will decrease the percentage of output as the process value increases within the proportional band.

On-Off Control / Latched On-Off 4.4

On-Off control can be implemented with SPST relay or SSR driver output(s) . On-Off operation can be assigned to either or both Output 1 and 2. A hysteresis adjustment is provided for On-Off Outputs. This adjustment is in terms of degrees/engineering units and defines the bandwidth of the hysteresis. The hysteresis value straddles the setpoint. Relay chatter can be eliminated by proper adjustment of this parameter. When operating in On-Off control, the output(s) will turn on or off depending upon the setpoint, the process value, Tune mode selections, and the hysteresis adjustment.

Resetting of an On-Off latched output (out1 = 8 or 9) is accomplished by pressing the UP arrow. The relay will stay reset only if the condition is cleared.

Time Proportioning Control 4.5

Time Proportioning control can be implemented with a SPST relay or SSR driver. Time

Proportioning control can be selected for Output 1 and/or Output 2, depending on hardware configuration. Time Proportioning control is accomplished by cycling the output on and off during a prescribed period of time when the process variable is within the proportional band.

Ex: Calculated output % = 40%; Cycle time adjustment = 20 seconds

Output on time = .4 x 20 = 8 seconds

Output off time = .6 x 20 = 12 seconds

When the unit is operating in the Control mode, the control algorithm determines the output % required to correct for any difference between the process value and the setpoint. The output calculation is affected by Tune mode parameter adjustments.

See Figure 4-1 (page 39) for proportional bandwidth effect on the output.

Current Proportioning Control 4.6

Current Proportioning control can be implemented on units provided with mADC current output(s). Current Proportioning control provides a 4 to 20mADC or 0 to 20mADC output in response to process value and setpoint. As with Time proportioning, the calculated output % for Current proportioning control is affected by the Tune mode parameter adjustments.

See Figure 4-1 (page 39) for proportional bandwidth effect on the output.

Position Proportioning Control 4.7

Position Proportioning Control can be implemented on those units provided with two SPST relay or two SSR driver outputs and the Position Proportioning (slidewire feedback) option.

Position Proportioning control permits the use of PID control when the final control element is a modulating device such as a motorized valve. Two outputs are required to control the valve. One output opens the valve, the second output closes the valve. The slidewire feedback is used to indicate the valve position to the instrument. The valve position will be dependant upon the process value, the setpoint and Tune mode parameters.

A Position Proportioning sensitivity adjustment is provided, which specifies a deadband around the setpoint to prevent the valve from oscillating. The valve rotation time must be entered, for proper operation, into the Tune mode paramter Ct1.

See Figure 4-1 for proportional bandwidth effect on the output.

The Proportional Bandwidth is the area where the output is a percentage of the full output. The size of the proportional band determines what change in the output will result from a change in the process variable. In the upper figure when the process variable is at 125 the output will be at 75% of full output. In the lower figure the proportional bandwidth is smaller. When the process variable is at 125 the output is now at 100%. The larger the proportional band the smaller the "gain" and vice versa.

Dual Output Control 4.8

Dual output control can be performed when two outputs are specified. The outputs may be programmed for On-Off, Time Proportioning, or Current Proportioning, as applicable.

The output action is dependent upon the setpoint, the process value, and Tune mode parameters. If two proportional outputs are selected, both output proportional bands will be biased so that 0 % of output is seen when the process value equals setpoint. The output(s) can be biased by the use of the Tune mode parameters FOP and SPrd as shown below.

Manual Operation of Proportional Outputs 4.9

The Auto/Manual switching function applies to proportional control outputs only.

Switching between the automatic and manual control modes is accomplished by scrolling to the Standby mode and pressing the DOWN key to enter the mode. Switching from automatic to manual is always bumpless.

CAUTION: If the unit is in the Manual mode, be careful not to leave the process unwatched. Since the unit is intentionally ignoring the setpoint, it is possible to unintentionally let the process exceed safe limits. Limit devices must be used to guarantee the process does not get out of control.

The proportional output values initially displayed upon entry into the Standby mode will be the last output values calculated by the control algorithm. Changes made to output values are made "on-line".

When the unit is placed in manual, Po1 and/or Po2, as approporiate, will appear in the display. If the keys are depressed within 5 second intervals, the units will respond as follows:

If a code is displayed:

SCROLL - The corresponding value will be displayed

DOWN - The next code will be displayed

If a value is displayed:

SCROLL - The next code will be displayed

UP - The value will increment

DOWN - The value will decrement

To exit from the Standby mode (manual operation), depress the UP key twice. (Pressing the

UP key once stops the cyclic display and leaves the controller in Standby) The controller will be in automatic control with Stby displayed. After a time-out period, the unit will display Crtl.

To get directly to the Ctrl display, press the UP key three times instead of twice. Shifting to the Control mode is balanceless.

Automatic Transfer Function 4.10

Automatic transfer provides automatic switching from the Manual mode to the Control mode of operation when the process value reaches setpoint. This feature is selectable in the Program mode.

NOTE: If an error condition occurs while in the Manual mode and Automatic Transfer

Function is selected, the output will go to a Failsafe condition.

Setpoint Adjustments 4.11

Local

Local setpoint adjustment is accomplished by using the keypad. Press the UP key to increase the setpoint value. Press the DOWN key to decrease the setpoint value. Holding the key pressed will cause the value to change slowly at first then increasingly faster. The range of the setpoint value can be limited by selecting the setpoint upper limit SPL in the

Program mode. The setpoint value can be protected from inadvertent changes by disabling the Setpoint Change, ESPC, in the Enable mode.

Ramp Rate - EB Option Only

A selectable Ramp Rate function can be used to limit the rate at which the setpoint used by the control algorithm will change. This feature will also establish a soft startup. Upon power up, the instrument will take the initial process value as the setpoint. A setpoint ramp will be calculated to increase the setpoint from the initial process value to the setpoint that was seen prior to the power outage.

Sudden changes in the setpoint value entered via the keypad can be inhibited from effecting the control outputs by use of this feature. The internal setpoint used to control the process will ramp to the setpoint value entered at the rate of change selected.

Process Re-transmission Output - EA Option Only

If the instrument is provided with a current output not used for process control, this output may be assigned to provide a linear re-transmission of the process value. This output can be used to provide a process signal to remotely installed recorders, panel meters, or data loggers.

The process output is scaled for the application by using the Program mode parameters process/setpoint output value upper Pou and process/setpoint output value lower PoL. The current output resolution is @ 200 steps, so for the best re-transmission accuracy, the span between Pou and PoL should be as small as possible. If a current output is used for retransmission, the corresponding control output, out1 or out2, cannot be assigned to it.

The example illustrated in Figure 4-4 (below) shows a process re-transmission application for

0 to 200 degrees F.

5.2.1 CAL 1 PARAMETER INITIALIZATION

This procedure is performed to erase the information that was entered in the Program and

Tune modes . All parameters will be reset to default values. Prior to beginning this procedure record the Program and Tune mode parameters so that they can be re-entered. No special test equipment is required.

With CAL1 displayed, depress and hold the DOWN key, then press the SCROLL key. The display will momentarily go blank. Release the keys. CAL1 will reappear on the display. This calibration can be done again or another may be selected.

5.2.2 CAL2 MAIN CALIBRATION

This procedure determines and saves calibration values which correct for component variations relating to the input measuring function of the instrument. This is the only calibration required for the volt and millivolt inputs. Additional calibration procedures are required for thermocouple and RTD inputs.

A 50.00

±

.01mVDC source is required for calibrating. In addition make sure that JU1 on the

Processor board is in the “non volt” position. See Appendix A-2 (page 60).

Make sure all input wiring is disconnected. Short the input terminals 1 and 3 or apply 0.00

mV to the input. With CAL2 displayed, press and hold the DOWN key, then press the

SCROLL key. Release both keys and the instrument will display hLd1. Depress the DOWN key; dELy will appear for up to ten seconds, then SCAn will appear for up to ten seconds. If the calibration reference number which appears is not between -50 and +50, proceed per note below. Otherwise, connect a 50.00

Press the DOWN key to bring the instrument back to dELy and try the calibration again. The calibration can be exited at anytime hLd1 or the reference number is displayed by pressing the SCROLL key.

CAL 2 QUICK CALIBRATION

This routine wil allow the operator to execute a rough calibration on their unit via the keypad with no other equipment or disturbance to established wiring. It is intended to provide a partial recovery from a calibration corruption where the necessary equipment indicated in Cal 2-5 may not be available. It should be noted that this is not intended as a substitution to the main calibration procedure described earlier and may considerably deter from the accuracy of the instrument.

With CAL2 displayed, press and hold the DOWN ARROW key, then press the SCROLL key.

Release both keys and the instrument will display hLd1. Press and hold the UP ARROW key, then press the SCROLL key. The display will momentarily blank and then CAL1 will be displayed. Release both keys and depress the UP ARROW key. CAL will be displayed.

5.2.3 CAL 3 COLD JUNCTION COMPENSATION

This procedure determines and saves calibration values which correct component variations relating to the cold junction compensation. This calibration must be preceeded by CAL2, the main calibration, to properly calibrate the instrument. These two calibrations are the only ones needed for proper operation with a thermocouple input.

Test equipment: one type J thermocouple and one mercury thermometer, accurate to

±

.25

degrees C or equivalent are required.

Make sure all input wiring is disconnected and connect the J thermocouple to the input. Place the thermometer next to the thermocouple and allow the controller to warm up for 30 minutes, before proceeding with the calibration.

With CAL3 displayed, depress and hold the DOWN key. Then press the SCROLL key and the unit will display hoLd. Release both keys. Press the DOWN key and deLy will be displayed for ten seconds, then SCAn for ten seconds. If SCAn remains in the display for much longer than ten seconds, refer to the note below. The instrument will compute and display the cold junction temperature to the nearest tenth of a degree C. Compare reading with thermometer and use the UP and DOWN keys to correct the reading, if necessary. To end the procedure press the SCROLL key and CAL3 will be displayed again.

NOTE: If the instrument continues to display in SCAn, proceed as follows. With SCAn displayed, press the SCROLL key. CAL3 should be displayed. With CAL3 displayed, while pressing the DOWN key, press and release the SCROLL key. The instrument will display

hoLd. Press the UP key. The instrument will begin the calibration procedure with a default value and proceed to deLy. Complete calibration as described above.

Error Recovery - see 5.4 ( page 52) for details on specific errors. The calibration can be exited at any time hoLd is displayed by pressing the SCROLL key.

5.2.4 CAL 4 COLD JUNCTION TEMPERATURE UTILITY

This procedure displays the temperature sensed by the cold junction compensator (CJC).

No special test equipment is required.

With CAL4 displayed, press and hold the DOWN key then press the SCROLL key and release both keys. SCAn will be displayed for ten seconds while the instrument computes the CJC temperature. The result will then be displayed to a tenth of a degree C.

The input terminals must be shorted with a jumper wire. Remember, the temperature displayed is that of the CJC terminals not the ambient temperature. To exit, press the

SCROLL key and CAL4 will be displayed.

5.2.5 CAL 5 RTD INPUT

This procedure determines and saves calibration values which correct for component variations relating to RTD inputs. This calibration must be preceded by CAL2 to properly calibrate the unit.

Test equipment needed will include a Decade Box (Resistance Substitution ) with .01% resolution or equivalent. Make sure the jumpers JU1 (Processor Board), JU2 and JU3

(Options boards) are in the proper positions for RTD input. See Appendix A-2 (page 60) and

A-3 (page 61, 62).

With CAL5 displayed press and hold the DOWN key, then press the SCROLL key and release both keys. hLd1 will then be displayed. Connect the Decade Box at 100 ohm setting across the input terminals 1 and 3 and Jumper terminals 1 and 5. Press the DOWN key and

dELy will be displayed for up to ten seconds, then SCAn for ten seconds. When hLd2 is displayed, connect 277 ohms to the input and press the DOWN key. Again dELy will display for up to ten seconds, followed by SCAn for ten more seconds. CAL5 will be displayed after the calibration is completed.

Error Recovery - See section 5.4 (page 51) for details about specific errors.

The Calibration mode can be exited any time the unit displays hLd1 or hLd2 by pressing the

SCROLL key.

5.2.6 CAL 6 COLD JUNCTION ON/OFF

With CAL 6 displayed, while pressing the DOWN ARROW key, press the SCROLL key. The instrument will display C6 and the number of the mode in effect. Mode 0 is the normal operating mode. The cold junction compensation is on. Mode 1 is the cold junction compensation disabled (off). Pressing the UP ARROW or DOWN ARROW will change the mode selection.

The relays should be checked for continuity when on and high impedance when off. SSR drivers will output 5 VDC when on and 0 VDC when off. This sequence may be repeated by using the DOWN key. To exit press the SCROLL key and tSt6 will be displayed. The existence of relay SSR outputs is dependent upon the hardware configuration.

5.3.7 TEST 7 - CURRENT OUTPUT 1 TEST

This test allows the user to verify that current Output 1 is functioning properly and will allow the adjustment of the current output value for testing of associated equipment. A volt meter with an appropriate shunt resistor or milliamp meter will be needed to execute this test. With

tSt7 displayed, depress and hold the DOWN key, then press the SCROLL key. Connect the

DVM or milliamp meter across the output terminals 5 and 6. The display will indicate 4 milliamps output. Use the UP and DOWN keys to vary the output in 1mA steps. The current output reading should be

±

0.5mA at any output value. To exit the test, press the SCROLL key and “tSt7” will be displayed. The existence of the mADC current output is dependent upon the hardware configuration as indicated by the model number.

5.3.8 TEST 8 - CURRENT OUTPUT 2 TEST

This test is the same as Test 7 except for Output 2. Check the output at terminals 7 and 5.

5.3.9 TEST 9 - AUXILIARY INPUT TEST

This test allows the operator to verify that the auxiliary inputs used for position proportioning (slidewire) feedback or remote setpoint is functioning properly. A variable voltage source, 5 VDC will be required to execute this test. With tSt9 displayed, press and hold the DOWN key then press the SCROLL key. The Auxiliary input voltage will be displayed to the nearest hundredth of a volt. Connect the +5V source across the Auxiliary input terminals (terminals 8 and 5) and adjust the voltage. Verify that the voltage displayed changes accordingly. The displayed voltage should be typically 0 - 5VDC

±

0.3

volts. To terminate the test, press the SCROLL key. The display will show tSt9.

The existence of the auxiliary input tested in Test 9 depends upon the hardware configuration as indicated by the model number.

5.3.10 TEST A - COMMUNCATIONS HARDWARE TEST

(Communications Option only)

This test allows the operator to verify that the communications hardware is functioning properly. With tStA displayed, press and hold the DOWN key then press the SCROLL key.

The display will indicate SEnd. Each time the DOWN key is depressed, the unit will toggle between SEnd and rEC (receive). With the desired function selected, depress the SCROLL key.

In the SEnd (send or transmit) mode, the instrument will repeat the following sequence.

First, the transmitter will go logic 1 for one second. Next, the transmitter will change the logic level to 0 for one second. Then, the transmitter will be disabled for one second. In the

rEC mode, the transmitter will be disabled. In either mode, the instrument will monitor the line logic level. The display will be rEC0 when a logic 0 is on the line . The display will be

rEC1 when logic 1 is on the line. In the SEnd mode, the unit will display rEC when the transmitter is disabled.

To perform an internal test to verify the operation of the hardware, place the instrument in the Send mode. Verify that the display cycles through rEC1, rEC0, and rEC. To verify that the transmitter functions properly, two LED’s, each with a current limiting resistor, can be connected to the communications terminals, with their polarities connected opposite of each other. The following three states will be produced: one LED on, then the other LED on, then both off. Alternately, a load resistor can be placed on the terminals, the voltage generated across the load resistor is as follows: > +3 VDC then > -3VDC and then 0 VDC. The terminals used are 7 & 8.

Another test method, would be to connect one or more instruments in the Receive mode to an instrument in the Send mode. The instruments in the Receive mode should have their display alternating in sync with the instrument that is in the Send mode. When the sending unit displays rEC, the receiving units should display rE1.

To terminate the test, press the SCROLL key for one second. Upon exit, tStA will be displayed.

Trouble-shooting and Diagnostics 5.4

This section consists of two columns. The first column is a list of some possible instrument conditions. The second column is a list of steps that should improve the condition. The steps should be performed in order until the condition improves or all the steps have been tried. If the instrument condition has not improved, contact the nearest representative or the factory for assistance.

Trouble-shooting should be performed by qualified personnel using the proper equipment and following all safety precautions. Whenever possible, the trouble-shooting should be accomplished with the electrical power disconnected. The instrument contains static sensitive components so care should be taken to observe anti-static procedures.

Model Number Displayed is incorrect

1. Verify that the correct instrument power, as

indicated on the wiring label on the housing, is

supplied to terminals A & B. If the voltage is not

correct, check the power source.

2. Turn off the instrument power. Wait about 5

seconds, then turn the power on again.

3. Turn off the instrument power, loosen the front

panel screw, and remove the instrument from the

housing. Inspect the instrument for poor

connections.

a. The white ribbon cable that connects the

Processor board (Appendix A-2, page 60)

to the Power Supply Board (Appendix A-

1, page 59) must be properly aligned

and seated.

b. The Front Display board pins should be

properly aligned and seated in the

sockets on the Processor board

(Appendix A-2, page 60) and the

Power Supply board (Appendix A-1,

page 59).

c. The Display Driver (U-1), located on the

Display board, must be free of corrosion

and firmly seated in the socket. Reinsert

the instrument in the housing, tighten the

panel screw, and turn on the power.

4. Turn off the instrument power. Press and hold the

UP and DOWN keys. Turn on the power. Hold

the keys depressed for about 10 seconds. If the

display lights the model number, Program and

Tune mode parameters will need to be re-entered

(page 28 & 33 or the Software Ref. Sheet, page

70, if already filled out).

1. Turn off the instrument power, wait 5 seconds then

reapply the power. Verify that the number dis-

played during the power up sequence is the same

as indicated on the label affixed to the lower front

of the display bezel.

Note: To re-initialize, follow steps 2 & 3.

2. Turn off the power to the instrument. Press and

hold the UP and DOWN keys and turn on the

power. Keep the keys depressed until the model

number resets to 2100-000. Release the keys

and turn off the power.

3. To enter the correct model number, press and hold

the SCROLL and DOWN keys and turn on the

instrument power, 2100 should be displayed.

Wait about 5 seconds and release the keys. The

display should remain 2100. Use the UP/DOWN

keys as necessary to change the displayed

number to match the first 4 digits of the model

number. After adjusting the first 4 digits to the

proper values, press the SCROLL key and the

display will change to 000-. Use the UP/DOWN

keys to set the last 3 digits of the model number to

the correct values. Press the SCROLL key and

the power up sequence will complete. The

Program and Tune mode parameters will need to

be re-entered (page 28 & 33 or the Software Ref.

Sheet, page 70, if already filled out).

Relay/SSR Driver Output(s)

1. Verify that the Program and Tune mode

Malfunction

parameters are correctly set (pages 28 & 33 or the

Software Ref. Sheet, page 70, if already filled out).

2. Turn off the power to the instrument. Wait about 5

seconds and turn the power on again. Confirm

that the model number displayed during the power

up sequence indicates that the output(s) is/are

present in the instrument. This number should

match the number on the label affixed to the lower

front of the display bezel. If model # is incorrect,

follow steps for "Model # displayed is incorrect".

3. Turn off the power to the instrument. Loosen the

front panel screw and remove the unit from the

housing. Inspect the Power Supply board

(Appendix A-1, page 59) for the presence of the

output device(s). Relay A is located at K1, Relay

B at K2, and Relay C at K3. A relay output will

appear to be a cube. The SSR Driver will appear

as a resistor and a jumper wire. The output will

not work if the hardware is not present.

4. Check the output operation by performing Test 6

as described in the Test section (page 48). If the

output(s) function(s) in the Test Mode re-examine

the Program and Tune Mode Parameters settings

(page 28 & 33, or the Software Ref. Sheet, page

68, if already filled out).

5. If the output appears not to turn off, remove the

power to the instrument. Loosen the front panel

screw and take the unit out of the housing. Clip

the resistor located on the Power Supply

(Appendix A-1, page 59) for the output(s) that

seem to stay on. A .01 microfarrad, 1 KV capacitor

should be connected from the terminal listed below, to

the AC ground for the output where the resistor

indicated was removed.

front of the display bezel. If model # is incorrect,

follow steps for "Model # displayed is incorrect"

(page 52).

3. Turn off the power to the instrument. Loosen the

front panel screw and remove the unit from the

housing. Inspect the Option board (Appendix A-3,

page 61, 62) for the presence of the Current Output

Driver IC. Current 1 output is U-1 and Current 2

output is U-5. The current output cannot function

without the hardware being present . Return the

instrument to the housing and tighten the front

panel screw.

4. Refer to the Test section (page 48) and carry out

the procedure for the output(s) that is/are not

working. Test 7 operates current Output 1 and

Glossary of Terms

Automatic Reset (Integration)

Automatic reset is a Tune mode parameter that will bias the proportional output(s) to compensate for process load variations. This parameter is adjustable from 0.0 to 100.0 repeats per minute. Factory default is 0.0. The display codes is ArSt.

Automatic Transfer

Automatic transfer is a Program mode parameter that will allow the instrument to switch from the Manual to the Control mode of operation automatically when the process value reaches setpoint.

Balanceless Transfer

This feature prevents changes in proportional output when changing from the Manual to

Control mode of operation. When transferring from the manual mode to the control mode, the proportional outputs will be "balanceless" regardless of whether the unit is inside or outside the proportional band. This only holds true if the Auto Reset (ArSt) value is greater than 0.

Bumpless Transfer

This feature prevents changes in proportional outputs when changing from the Control to the

Manual mode of operation only.

Control Algorithm

A pre-programmed series of instructions that are used by the instrument when determining the status of the output(s).

Cycle Time

This Tune mode parameter is used to select the on/off cycle time for time proportioning outputs (Ct1 for Output 1 and/or Ct2 for Output 2). (See page 29, section 4.5)

When using the Position Proportioning option, Ct1 must be selected for the stroke time of the motor.

Display Filter Factor

This Program mode parameter is used to dampen the process value displayed. The selections range from 1 through 20, the value represents the number of process scans that will be averaged for the display value. Factory default is 1, no filtering.

Engineering Units Upper and

Engineering Units Lower

These Program mode parameters are used with volt, millivolt, and milliamp inputs. The

Engineering Units Upper Euu should be selected as the value to be displayed when the input is at maximum. The Engineering Units Lower EuL should be selected as the value to be displayed when the input is at minimum.

First Output Position

This parameter is adjustable from -1000 to 1000 units and represents a shift or offset of the on-off actuation points or proportional band for the first output relative to the normal position.

For example, a negative value could be used to offset an expected overshoot. First Output

Position also shifts the proportional band with respect to the process value range outside of which integral action is inhibited. Factory default is 0. Display code FoP.

P

AGE

63

P

AGE

64

Hysteresis

This parameter is adjustable from 0 to 300 units representing the width of the band (half above and half below setpoint). Used with On-Off or Alarm outputs to reduce cycling. For instance, with a value of 4 and a setpoint of 70, the output will turn On when the process variable drops to 68 and stays On until 72 is reached, then turns Off the output. Factory default is 3. Display code is HySt.

Input Correction

This parameter is used to adjust the process variable value to compensate for sensor errors.

This Program mode parameter is selectable from -300 to + 300 degrees/units. The factory default is 0.

Manual Reset

This parameter is adjustable from -1500 to 1500 units representing a manual shift of proportional band(s) relative to the normal position. Manual reset is intended to be used when automatic reset is not used to allow compensation for deviations from setpoint which remain after the process has stabilized. Factory default is 0. Increasing the value increases the process variable, i.e. if the process variable stabilized too low, increase the manual set.

Integral action, and conversely reset-windup inhibit apply over the same process value range regardless of the manuals reset value. Display code rSEt.

Position Proportioning Sensitivity

A percentage of the first output proportional band width (Pb1).

Process Filter Factor

This Program mode parameter is used to dampen the process value used to calculate output action. The process value is averaged to dampen the control outputs. This parameter is adjustable from 1 to 20 . Factory default is 1.

Process Retransmission Output (EA Software Option)

This parameter allows for a linear milliamp proportional output relative to the process value.

The current output may be scaled over a range selectable by the user. This output can be used to supply the process variable signal to remote chart recorders, panel meters, and data logger instruments.

Process Output Upper and Lower Values (Used in conjunction with process or setpoint retransmission output)

These parameters specify the process or setpoint value range over which the assigned current output will vary in a linear manner from 100% to 0%. If the process or setpoint value is greater than Pou, the output will be 100%. If the process or setpoint value is less than PoL, the output will be 0%. Factory default values are 2000 for the upper value and 0 for the lower value. Display codes Pou (upper) and PoL (lower).

Process Rounding

This Program mode parameter is used to determine the step size of the process value that will be seen on the display. This feature can be used to reduce display fluctuation. This parameter is adjusted from 1 to 100 degrees/units. The factory default is 1, no rounding (e.g.

Process rounding = 2, Process Value Display - 4, -2, 0, 2, 4, etc.).

Process Variable

The process variable refers to the condition of the process being measured (sensed). The instrument will accept process inputs other than temperature (pressure, level, flow, etc.).

Proportional Band

This Tune mode parameter selects the span of the proportional output range. This parameter is adjustable from 1 to 3000 degrees/units. Factory default is 100. If Output 1 is selected as a proportional output, a display code of Pb1 will be seen. If Output 2 is selected as a proportional output, the display code will be Pb2.

Rate (Derivative)

This parameter is adjustable from 0.0 to 10.0 minutes and specifies how the control action responds to the rate of change in the process variable. For example, if the process variable is rising rapidly to setpoint, power is turned off sooner than it would be if the rise were slow. In effect, derivative action anticipates lags within the system and shifts the proportioning band by an amount determined by the rate of change of the input sensor. Magnitude of the shift is determined by a derivative time constant. If the time constant is, say, .1 minute (6 seconds), for every unit per second rate of change of the process variable at the sensor, the proportioning band is moved 7 units in the direction that helps control. Likewise, if the time constant is 1 minute (60 seconds), for every unit per second rate of change of the process variable at the sensor, the proportioning band is moved 60 units in the direction that helps control. Factory default is 0.0. Display code rAtE.

Setpoint Re-transmission Output (EA Software Option)

This parameter allows for a linear milliamp output relative to the setpoint value. The current output may be scaled over a range selectable by the user. This output can be used as a manual setting station.

Spread (Second Output Position)

This parameter is adjustable from -1000 to 1000 units and represents a shift or offset of the on-off actuation points or proportional band for the second output relative to the normal position. A positive value creates a gap where no control outputs are on, a negative value creates an overlap of control outputs (if the first output position is at the normal position).

Second Output Position also shifts the proportional band with respect to the process value range outside of which integral action is highlighted (reset-windup inhibit). Factory default is

0. Display code SPrd.

Setpoint Ramp Rate

This Program mode parameter provides a rate of change control of the instrument setpoint value. This parameter is used to inhibit sudden upsets in the instrument control caused by large setpoint changes. This feature also creates a soft start when the instrument power is turned on. The instrument will read the process value at the time the power was turned on as the setpoint value. A rate of change ramp will change the internal setpoint to the setpoint seen by the instrument at the time the power was turned off.
