Section 4—Application Information
ENGLISH
SECTION 4— APPLICATION INFORMATION
DESIGN FEATURES
Silicon Controlled Rectifier (SCR) Power
Modules
For each phase, the SCRs are matched devices arranged in inverse parallel
pairs and in series strings to facilitate sufficient peak inverse voltage (PIV)
ratings for the applied voltage (see Table 2 on page 12).
Resistive, Capacitive (RC) Snubber
Networks
RC snubber networks provide transient voltage protection for SCR power
modules in each phase to reduce dv/dt damage.
Firing Circuit
The SCRs are gated (turned on) using a sustained pulse firing circuit. This
circuitry is amplified and isolated from the control voltage by means of fiber
optics for current and ring transformers.
Vacuum Contactors
A sequencing feature controls the vacuum contactors. Under normal
operating conditions, this ensures that both the in-line and SCR bypass
contactors make and break under no-load conditions to maximize contactor
life. Both contactors are rated for the maximum starting requirement of the
unit design. The bypass contactor is rated to be capable of emergency start.
Low Voltage Control Compartment
A low voltage control compartment houses the digital microprocessor
controller and LCD keypad operator interface, along with any other low
voltage devices. This allows the operator to make adjustments without
exposure to the line voltages.
THEORY OF OPERATION
The power of the Motorpact™ Soft Start is in the central processing unit
(CPU), a microprocessor-based protection and control system for the motor
and starter assembly. The CPU applies a reduced voltage to the motor by
phase angle firing the SCRs, and then slowly and gently increases torque
through control of the voltage and current until the motor accelerates to full
speed. This starting method
Acceleration

Motorpact™ Soft Start
Section 4—Application Information
Default Setting
46032-700-04
12/2003
ENGLISH
The default setting applies a Voltage Ramp with Current Limit, the most
reliable starting method for the vast majority of applications. Using this
starting method, the Initial Torque setting applies just enough voltage to the
motor to cause the motor shaft to begin to turn. This voltage is then gradually
increased over time (as per the Ramp Time setting) until either:
•
•
•
the motor accelerates to full speed,
the Ramp Time expires, or
a Current Limit setting is reached.
If the motor accelerates to full speed before the ramp time setting has
expired, an automatic anti-oscillation feature will override the remaining
ramp time and apply full voltage.
If the motor has not reached full speed at the end of the ramp time setting,
the current limit setting will proportionally control the maximum output
torque. Feedback sensors in the soft start provide protection from a stall
condition, an overload condition, or excessive acceleration time.
The Current Limit feature accommodates installations with limited power
available. The torque is increased until the motor current reaches the preset
Current Limit point and then holds it at that level. Current Limit overrides the
ramp time setting. Therefore, if the motor has not accelerated to full speed
under the Current Limit setting, the current remains limited for as long as it
takes the motor to accelerate to full speed.
When the motor reaches full speed and the current drops to running levels,
the soft start detects an At-Speed condition and closes the Bypass
Contactor. The Bypass Contactor shunts power around the SCR stack
assemblies. At this point, the motor is operating at full voltage.
Current Ramp
This starting method uses a closed current feedback PID loop to provide a
linear torque increase up to a maximum current level.
Constant Current
With this method, current is immediately increased to the Current Limit point
and held there until the motor reaches full speed.
Custom Curve
The Custom Curve method gives the ability to plot torque and time points on
a graph. The soft start will then accelerate the motor following these points.
Tachometer Feedback Ramp
The Tachometer Feedback Ramp uses a closed loop speed follower method
monitoring a tachometer input signal from the motor or load shaft.
Deceleration
The Motorpact Soft Start provides the option of either having the load coast
to a stop, or controlling the deceleration by slowly reducing the voltage to the
motor upon initiating a stop command. The Decel feature is the opposite of
DC injection braking, since the motor will actually take longer to come to a
stop than if allowed to coast to a stop. The most common application for the
Decel feature is pumping applications in which a controlled stop prevents
water hammer and mechanical damage to the system.

Section 4—Application Information
GENERAL PROTECTION
Motorpact Soft Start operation can be divided into 4 modes: Ready, Start,
Run, and Stop. The CPU provides motor and load protection in all four modes.
Ready Mode
In this mode, control and line power are applied and the soft start is ready for
a start command. Protection during this mode includes current monitoring for
leakage through multiple shorted SCRs or welded contacts on the bypass
contactor. Other protection features in effect are:
•
•
•
•
•
•
Starter temperature
Shorted SCR
Blown fuse indication
Phase reversal (if enabled)
Line frequency trip window
External input faults
The “Programming Mode” can only be entered from the Ready
Mode. During programming, all protection features and start
commands are disabled.
Start Mode
These additional protection functions are enabled when the soft start
receives a valid Start command:
•
•
•
•
•
•
•
•
•
•
Phase reversal (if enabled)
Start curve
Acceleration timer
Phase imbalance
Short circuit / load pre-check (toe-in-the-water)
Ground fault
External input faults
Accumulated starting FLA units (I2t protection)
Overload protection
Thermal capacity
Shorted SCR and shunt trip protection are no longer in effect once
the soft starter goes into the Start mode.
Run Mode
The soft start enters the Run mode when it reaches full output voltage and
the motor current drops below the FLA setting (motor nameplate FLA plus
service factor) for a pre-determined period of time. During the Run mode,
these additional protection features are enabled:
•
•
•
•
•
Stop Mode

Running overload curve
Phase loss
Under current/load loss
Over current/electronic shear pin
External input faults
Once a Stop command has been given, the Motorpact Soft Start protection
features change, depending on which Stop mode is selected.

THERMAL OVERLOAD
PROTECTION
The Motorpact Soft Start monitors the motor for excessive thermal
conditions due to starting, running, or ambient conditions. The dynamic
thermal register system in the CPU provides a mathematical representation
of the thermal state of the motor. This thermal state information is derived
from current imbalances and (optional) RTD measurements, and is retained
and monitored for excesses in value and rate of change. The soft start
monitors these conditions separately during Start and Run modes to provide
proper thermal overload protection at all times.
Start Mode Overload Protection
You can select Start mode overload protection by using one of three
methods:
Basic Protection
I2t data is accumulated and plotted based on an overload curve selected in
programming. The curve is programmed per NEMA Class 5-30 standard
curves and is based on the locked rotor current (from the motor nameplate)
as programmed into the soft start.
Measured Start Capacity
The user enters a measured amount of thermal capacity from a pre-selected
successful start as a setpoint to the thermal register.
Learned Curve Protection
The user sets the soft start to the “LEARN” mode and starts the motor under
normal starting conditions. The CPU then samples and records 100 data
points during the start curve, analyzes them, and creates a graphical
representation in memory. The soft start is then switched to Curve Follow
protection mode and monitors motor performance against this curve. This
feature is useful in initial commissioning tests to record a base line
performance sample (in this case, it is not necessarily used for motor
protection).
16
© 2003 Schneider Electric All Rights Reserved
Run Mode Overload Protection
Motorpact™ Soft Start
Section 4—Application Information
This protection is initiated when the Motorpact Soft Start determines that the
motor is at speed. This occurs when the motor RMS current rises above a
“pick-up point” (as determined by the motor nameplate FLA and service
factor). Run mode protection is provided by the CPU monitoring the dynamic
thermal register. Data for the dynamic thermal register is accumulated from
I2t calculations and cooling rates. A trip occurs when the register reaches
100% as determined by the selected overload protection curve (NEMA
Class 5–30 standard curves) and is based on the programmed locked rotor
current indicated on the motor nameplate. The dynamic thermal register is
altered, or “biased”, by the following conditions:
•
Current Imbalance will bias the register higher to add protection from
additional motor heating during a current imbalance condition.
•
Normal Cooling is provided when the motor current drops below the
pick-up point or the motor is offline. The cooling rate is lower for offline
motors (such as after a trip) since cooling fans are also inoperative.
•
RTD Input (requires the optional RTD monitor card) will bias the register
in either direction based on real-time input of the motor, bearing, and
ambient temperature conditions.
•
Dynamic Reset: If a motor overload condition occurs and the soft starter
trips, it cannot be reset until sufficient cooldown time has elapsed. This
cooldown time is determined by the thermal state of the motor when it
tripped. The cooldown time is also biased by RTD measurements, when
used.
Retentive Memory
Retentive Memory provides continuous overload protection and real time
reset, even if power is lost. When power is restored, the soft start will read
the real time clock and restore the thermal register to the correct value.
Learned Reset Capacity
The Motorpact Soft Start samples the amount of thermal capacity used in
the previous three successful starts, and will not allow a reset until the motor
has regained a sufficient amount of thermal capacity. This prevents
nuisance tripping and unsuccessful start attempts.

ENGLISH
SCR GATE FIRING CIRCUIT
The Motorpact Soft Start contains a firing circuit that includes several unique
features that maximize performance, without the need for reactors or field
installed devices used in other systems, regardless of conditions. These
features include:
Auto Synchronizing
Auto Synchronizing of the gate timing pulses matches each phase firing
angle to their respective phases. The soft start actively tracks minor shifts in
the line frequency, avoiding nuisance tripping that may happen with
conventional gate firing systems.
Sustained Pulse Firing
Sustained pulse firing keeps the firing signal active for 270 electrical
degrees, ensuring that the dc gate pulse causes the SCR to fire even if line
noise is present at a critical moment. This provides noise immunity and
protects against misfiring, enhancing system reliability.
Closed Loop Firing Control
Closed loop firing control is a method of balancing the SCR firing pattern
based on the desired output. The CPU uses feedback signals from both the
output current and voltage, providing smooth output and preventing
imbalances during ramping and unnecessary motor heating.
Transformer Isolation
Transformer isolation of the firing signals prevents interference from line
noise and EMI/RFI signals that may be present. Specially designed 120 V,
3-phase isolation transformers provide potential measurement, firing board
power, and gate power systems while isolated from the line voltage. High
isolation ring transformers are used to step this down to 28 Vac for the
sustained pulse firing circuit, providing further isolation for the SCR gates.
Additional magnetic isolation is provided via a separate control power
transformer (CPT), which powers the low voltage controls and the CPU.
Fiber Optic Isolation
Fiber optic isolation is provided for all signal interfaces between the medium
and low voltage systems. The current signals from CTs are converted to
fiber optic signals for maximum isolation.

Motorpact™ Soft Start
Section 4—Application Information
ELECTRONICS
Motorpact Soft Start electronics systems are divided into two categories, low
and medium voltage.
Low Voltage
Low voltage electronics include the keypad operator interface, CPU, and
main power PC boards, and are located in isolated low voltage
compartments of the enclosure.
Keypad Operator Interface
This is a 2-line x 20-character LCD display with backlighting for low ambient
conditions. The display reads out in truncated English and can show multiple
data points in each screen. Also included are 12 LED indicators, which
include Power, Run, Alarm, Trip and the status of the 8 auxiliary relays. It
communicates to the CPU via a serial link and, if necessary, can be remotely
mounted up to 1000 ft. (305 m) from the soft starter.
CPU Board
This is where the microprocessor and communications co-processor reside.
The CPU Board is attached to the main power board, and communicates to
it and the keypad operator interface via serial links. The CPU determines
operating functions, stores user programming, and acts on feedback signals
for faults, metering, and historical data. This board also contains the flash
EEPROM and SRAM memory, as well as the analog I/O and terminations.
Main Power Board
This is also referred to as the firing board. It contains the digital I/O relays
and interfaces to the TCB for user interface. See “Terminal and Control
Board (TCB)” below. It also controls the sequencing of the isolation and
bypass contactors with the SCR firing. This board generates all firing signals
for the SCR stacks and receives feedback signals from fiber optic
transmitters. It converts analog levels to digital signals for the CPU. These
firing pulses are via fiber optic signals to isolate them from the medium
voltage environment.
Medium Voltage
Control electronics are located in the medium voltage section of the soft
start. The main line power must be disconnected before accessing these
electronics, which include the TCB (terminal and control board), gate drive,
and temp/CT (current transformer) boards.
Terminal and Control Board (TCB)
This is the user connection interface board. It is located in the medium
voltage section in order to satisfy UL termination requirements, but does not
actually connect directly to the medium voltage components other than the
contactor coils. This board contains the user terminal blocks, output relays
(duplicated), inputs, and control power connections. It also contains
additional timed relays for interfacing with power factor correction contactors
(if used) and other external devices.
Gate Drive Boards
These are located directly on the SCR stacks. These boards communicate
to the main power board via fiber optic cables. They amplify the gate pulse
signals with power from the ring transformers to create the sustained pulse
firing of the SCRs. There is one gate drive board for each pair of SCRs in
each stack.
Temp/CT Boards
These boards are attached to the gate drive boards on the SCR stacks and
provide the heat sink temperature and current signals back to the main
power board via fiber optic cables.
MOV Boards
These boards are attached to the standoffs mounted on the SCR heat sinks
and are mounted directly below the Gate Drive boards. The MOV boards are
used to protect the gate/cathode section of the SCRs.
DV/DT Boards
The DV/DT boards are used to reduce voltage transients across the stack
assemblies.

If adjustments are required, see “Setpoint Page 2” on page 42.
ACCELERATION ADJUSTMENTS
The unit is set at the factory with typical starting characteristics that perform
well in most applications. When the system is ready to start, try the initial unit
settings. If the motor does not come up to speed, increase the current limit
setting. If the motor does not start to turn as soon as desired, raise the
starting voltage adjustment. See Figure 3 and Table 4 for adjustment

DECELERATION ADJUSTMENTS
Deceleration extends the stopping time on loads that would otherwise stop
too quickly if allowed to coast to stop. Deceleration control provides smooth
deceleration until the load comes to a stop. Three adjustments— start
deceleration voltage, stop deceleration voltage, and deceleration time—
optimize the deceleration curve to meet the most demanding requirements
(see Table 5 on page 23).
The Motorpact™ Soft Start is shipped from the factory with the decel feature
disabled. Before enabling or modifying the deceleration adjustments, apply
power and adjust the soft start. Make any acceleration and deceleration
adjustments under normal load conditions.

The primary use of deceleration is to reduce the sudden changes in
pressure that are associated with “water hammer” and slamming of check
valves with centrifugal pumps (see descriptions below). Deceleration control
in pump applications is often referred to as “pump control.”
In a pump system, liquid is pushed uphill. The force exerted by gravity on the
column of liquid as it travels uphill 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. The 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 it dissipates (see Figure 4). The sound of that
shock wave is referred to as “water hammer.” Shock wave energy can be
extremely damaging to pipes, fittings, flanges, seals, and mounting systems.
The soft stop/deceleration feature of the Motorpact Soft Start gradually and
gently reduces the pump output torque and pressure in the pipe. When the
output pressure is just slightly lower than the 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 a shock wave is avoided. When the output
voltage to the motor is low enough to no longer be needed, the soft start will
end the Decel cycle and turn itself off.
Another common application for decel control is on material handling
conveyors as a means to prevent sudden stops that may cause products to
fall over or to bump into one another. In overhead crane applications, soft
stopping the bridge or trolley can prevent loads from over-swinging on
sudden stops.

CAUTION
HAZARD OF EQUIPMENT DAMAGE
Never operate the emergency bypass contactor with power applied to the
soft start.
Failure to follow this instruction will result in equipment damage.
In the emergency bypass mode, there is no overload protection
unless a separate (optional or customer-supplied) thermal overload
relay is installed.
Bi-metallic overload protection is required, and is supplied with the
equipment when the emergency overload protection option is
selected. If this option is not included, the customer must supply
bi-metallic overload protection.
1. Remove input power by using the line start section and lockout
disconnect. To do this, open the main contactor, move the isolation
means to the grounded position, and lock it out.
2. Close the emergency bypass contact. See Section 6—Control
Connections for the Terminal and Control Board on page 26.
3. Reclose the disconnect on the line start panel.
The line start panel is operable as a normal across-the-line starter. When
power is applied, the bypass contactor energizes, tying the input
terminals directly to its output terminals. When the “ON/OFF” contact is
closed, the main contactor energizes and the motor line starts. When the
“ON/OFF” contact is opened, the motor is disconnected from the line via
the main in-line vacuum contactor.

Motorpact™ Soft Start
Section 7—Control Connections for the Terminal and Control Board
46032-700-04
12/2003
ENGLISH
The Motorpact™ Soft Start TCB board provides interconnections between
the main power and CPU boards and the customer’s control logic
connections. The TCB board is a 120 Vac control board with several
auxiliary dry control contacts, built-in time delay circuits, and emergency
bypass functions. It also controls the sequence of the inline isolation and
bypass contactor, and provides provisions for shutdown interlocks.
START/STOP CONTROL—
TERMINAL BLOCK 1 (TB1)
Positions 1 and 9 are the Vac control power. The recommended VA is
750 VA or higher.
NOTE: The current power transformer (CPT) that is included in Motorpact
Soft Start units should not be used for other 120 Vac operations or power
sources.
Positions 2-3 and 4-5 are jumpered at the factory and can be removed for a
customer’s normally closed, dry, shutdown contacts.
Positions 6-7-8 are for either two-wire or three-wire start/stop logic. Two-wire
control is connected to positions 6 and 8 with a normally open (N.O.) dry,
maintained start/stop contact. Three-wire control is connected to 6 with 7 as
the stop pushbutton, and the start pushbutton is connected to 7 and 8.
Positions 10-11-12 are a dry Form C contact. The contact is an immediate
start/stop contact.

Positions 1 and 2 are for an emergency bypass contact. If a dry contact
closes positions 1 and 2, the CPU is shut off and there is no display. Then,
when a start is initiated, it pulls in the inline isolation contactor, starting the
motor across the line.
Positions 3-4-5 are for a Form C contact. This is a dry contact initiated when
the emergency contact is closed. It indicates the emergency bypass mode.
Positions 6 and 7 are for a customer connection for control power. Position 6
is the 120 Vac supply at 400 VA and position 7 is the return.
CAUTION
HAZARD OF EQUIPMENT DAMAGE
When using the contactor in the Emergency Bypass mode, the electronic
overload protection is no longer functional. You must provide external
motor overload protection.
Failure to follow this instruction can result in equipment damage.

Section 7—Control Connections for the Terminal and Control Board
Positions 8-9-10 are a Form C contact. It is a dry, delayed, start/stop contact.
The amount of delay is determined by X1, X2, and SW3 (see “Jumper
Selection” and “Switch Positions” on page 31).
NOTE: Additional time delay to SP2 of the CPU programming.

Positions 1-2-3 and 4-5-6 are sets of Form C contacts. They are auxiliary
time delay contacts that will change state (after a delay) when the Start
contact is initiated. X3, X4, and SW4 (see Figure 12 on page 31) determine
the amount of delay. See “Jumper Selection” and “Switch Positions” on
page 31.
Positions 7-8-9 and 10-11-12 are also sets of Form C contacts. They are
power factor correction (PFC) capacitor contacts that pull in an isolation
contactor for the PFC capacitors, if required by the application. The PFC
capacitor contacts change state when the At Speed contact is initiated. X5,
X6, and SW5 (see Figure 12 on page 31) determine the amount of delay.
See “Jumper Selection” and “Switch Positions” on page 31.
NOTE: Additional time delay to SP2 of the CPU programming.

TERMINAL BLOCK 5 (TB5)
Terminal block 5 is for RS-485 connections: appropriate software is
required. Contact the factory. If the wiring distance is less than 25 ft. (7.6 m),
use termination resistors as needed. Minimum 22 gauge twisted-pair wiring.
TERMINAL BLOCK 6 (TB6)
Terminal block 6 is wired at the factory, and contains main power board
connections 1–12 (see Figure 18 on page 34).
TERMINAL BLOCK 7 (TB7)
Terminal block 7 is wired at the factory, and contains main power board
connections 13–24 (see Figure 18 on page 34).
TERMINAL BLOCK 8 (TB8)
If a complete Motorpact NEMA E2 controller is supplied, terminal block 8 is
wired at the factory. If only a soft start is supplied, the customer wires the
terminal block.
Positions 1 and 2 accept dry, normally closed (N.C.) contacts from blown
fuse indicators and/or a disconnect interlock contact.
Positions 3 and 4 accept dry, N.C. contacts from an external overload
protection device (required if using emergency bypass mode).
Positions 5 and 6 accept dry, N.C. contacts from the bypass contactor for an
At Speed indication. These positions are wired at the factory.
Positions 7 and 8 are wired at the factory to the coil of the bypass contactor.
They energize and de-energize the contactor.
NOTE: All customer contacts are 960 VA, 120 Vac (max.) rated dry contacts.

Password Access
You can change screens in Level 1 of the setpoint menu without password
access because these screens list basic motor information only. Screens in
Levels 2 and 3 require passwords because they provide more in-depth
protection and control of the Motorpact Soft Start unit. You can change the
password in Levels 2 and 3.
Changing Setpoints
Setpoints can only be changed when the motor is in the Stop/Ready mode.
The Motorpact Soft Start will not allow a start if the motor is still in the Edit
mode. To determine if the unit is in Edit mode, check the top right corner of
the display: an asterisk (*) indicates the unit is in Edit mode.
Example

explanations of start ramp types.
0–100%
Set the initial level to provide enough torque to start rotating the motor
shaft, enabling a soft start and preventing torque shock damage. Setting
this start point too high will not damage the starter, but may reduce or
eliminate the soft start effect.

(torque) setting to either of the following:
Ramp time #1

2.
the current limit setting when the motor is still accelerating, or
full output voltage if the current limit is set to maximum.
Increasing the ramp time softens the start process by gradually
increasing the voltage or current. Ideally, the ramp time should be set for
the longest amount of time the application will allow, without stalling the
motor.
Sets the maximum motor current the starter will allow during ramping.
Current limit remains in effect until the motor reaches full speed (detected
by the At-Speed detection circuit), or the overload protection trips on

Figure 24:
Voltage Ramping: (see Figure 24) Voltage is increased from a starting point
(Initial Torque) to full voltage over an adjustable period of time (Ramp Time).
To achieve voltage ramping, select Voltage for the Start Ramp #1 Type
setpoint and set the Current Limit #1 setpoint to 600% (the maximum
setting). Since this is essentially locked rotor current on most motors, there
is little or no current limit effect on the ramp profile.

Start Ramp #1 Type: Voltage
Voltage Ramping with Current Limit: Voltage is gradually increased until
the setting of the maximum current limit setpoint is reached. The voltage is
held at this level until the motor accelerates to full speed. To achieve voltage
ramping with current limit, select Voltage for the Start Ramp #1 setpoint and
set the Current Limit #1 setpoint to a desired lower setting, as determined by
your application requirements.
Current Ramping (Closed Loop Torque Ramping): Output voltage is
constantly updated to provide the linear current ramp; therefore, the
available torque is maximized at any given speed.
This feature can be used with or without the maximum current limit setting.
To achieve current ramping, select Current for the Start Ramp #1 Type
setpoint and set the Maximum Current #1 setpoint to the desired level.
The Current Limit Only (Current Step) start uses the current limit feature
exclusively. This starting method eliminates the soft start voltage/current
ramp and instead, maximizes the effective application of motor torque within
the limits of the motor. In this mode, the Ramp Time #1 setpoint is set to zero
(0), so the output current jumps to the current limit setting immediately. Start
Ramp #1 Type is set to either Voltage or Current.

energy management programs where processes may be altered or scheduled to
reduce overall demand. Demand is calculated by a programmed amount of time

A relay configured as non-latching will reset itself
when the cause of the trip event is not continuous.
AUX6 relay fail-safe
AUX6 relay latched
The Trip (AUX1) relay should always be

soft start will switch to start ramp #2 and use that setting
for start control mode. The start ramp types should only
be switched while the motor is stopped. In Setpoint Page

soft start will ship with External input #3 programmed for
dual ramp. If it is not needed, disable the dual ramp.
These input screens are for thermostat input. It is
recommended that this function remain enabled. If the
thermostat indicates an over temperature condition, the
soft start will trip the motor.

Setpoint Page 7 allows you to custom
design the acceleration (start) curve to a
specific application. You can design up to
three different curves in the soft start. Only
one curve at a time can be active
(enabled). Each of the three custom curves
has eight voltage levels, with
corresponding ramp times and a current
limit setting.
You must program each successive
voltage level to one greater than the
previous level. All eight voltage levels must
be programmed. The eighth level has been
preset to 100%.
If the custom accel curve is set to curve A,
B, or C on Setpoint Page 7, the soft start
will override the start control mode
selected in Setpoint Page 2, even if the
start control mode is not set to custom
accel curve.

The Motorpact Soft Start is available with an optional RTD card that provides
12 programmable RTDs. The available types are 100 ohm platinum, 100
ohm nickel, 120 ohm nickel, and 10 ohm copper. Each RTD can be identified
with a description name of up to 15 characters (including spacing). Also,
each individual RTD has its own alarm and trip level.

SECTION 9— MAINTENANCE AND TROUBLESHOOTING
ENGLISH
MAINTENANCE
DANGER
HAZARD OF ELECTRIC SHOCK,
EXPLOSION, OR ARC FLASH
• This equipment must be installed and
serviced only by qualified electrical
personnel.
• Qualified persons performing diagnostics or
troubleshooting that require electrical
conductors to be energized must comply
with NFPA 70 E – Standard for Electrical
Safety Requirements for Employee
Workplace and OSHA Standards – 29 CFR
Part 1910 Subpart S - Electrical.
Failure to follow these instructions will
result in death or serious injury.
Periodically check the equipment for dirt, moisture, or industrial
contaminants. These can cause high voltage arc-over, carbon tracking, or
prevention of proper SCR heat sink cooling.
Annually, check all bolts for proper tightness, using an accurate torque
wrench.
If the soft start is installed in a contaminated environment using forced air
cooling, regularly check and clean blower filters to ensure that air flows
properly and the enclosure is cooled properly.

maintenance procedures and guidelines:
•
bulletin # 46032-700-02 for 200/400/450 A Motorpact vacuum
contactors
Refer to the NEMA Motorpact Medium Voltage Motor Controller
bulletin, # 46032-700-06, for general equipment maintenance
procedures.
TROUBLESHOOTING
For general equipment troubleshooting, refer to the appropriate
Motorpact Medium Voltage Motor Controller bulletin:
# 46032-700-06 for NEMA enclosures
When the soft start experiences a problem, the LCD will display the error.
The LED and auxiliary relays displayed will light. Table 30 on page 77 lists
possible problems, associated displays, LEDs, and auxiliary relays, possible
causes, and solutions to remedy the problem. Clear all problem displays
before attempting to restart the soft start.
If the problem persists after making all required programming changes and
taking all corrective action, contact the factory for assistance.

HAZARD OF ELECTRIC SHOCK,
EXPLOSION, OR ARC FLASH
• This equipment must be installed and
serviced only by qualified electrical
personnel.
• Qualified persons performing diagnostics or
troubleshooting that require electrical
conductors to be energized must comply
with NFPA 70 E – Standard for Electrical
Safety Requirements for Employee
Workplace and OSHA Standards – 29 CFR
Part 1910 Subpart S - Electrical.
Failure to follow these instructions will
result in death or serious injury.
1. Open the test switch and stop the motor.
2. Setpoint Page 5 AUX4 is set to non-fail safe. Change this setpoint to fail
safe. See “Setpoint Page 5” on page 51.
3. Make sure that the bypass contactor closes immediately.
4. Place the oscilloscope on the 2 ms time scale and 1 V per division.
5. Connect the oscilloscope probe to the gate and cathode of the SCRs.
The gate and cathode leads are the white wires on the soft start gate
drive (GD) board in the medium voltage compartment.
6. If the waveform is inverted, swap the oscilloscope connections to
achieve proper polarity. Close the temporary Start switch and allow the
test motor to reach full speed.
7. Verify that all gating signals connect to each SCR (there are two gating
signals on every GD board). See Figure 51 for an example of a correct
waveform.
8. If any improper signals are found, note their location(s) and contact the
factory.

Procedures
DANGER
HAZARD OF ELECTRIC SHOCK,
EXPLOSION, OR ARC FLASH
• Only qualified personnel familiar with
medium voltage equipment are to perform
work described in this set of instructions.
• Apply appropriate personal protective
equipment (PPE) and follow safe electrical
work practices. See NFPA 70E.
• Turn off all power before working on or inside
equipment.
• Use a properly rated voltage sensing device
to confirm that the power is off.
• Before performing visual inspections, tests,
or maintenance on the equipment,
disconnect all sources of electric power.
Assume that all circuits are live until they
have been completely de-energized, tested,
grounded, and tagged. Pay particular
attention to the design of the power system.
Consider all sources of power, including the
possibility of backfeeding.
• Replace all devices, doors, and covers
before turning on power to this equipment.
Failure to follow these instructions will
result in death, serious injury, or equipment
damage.
1. Using a properly rated voltage testing device, verify that no DC or AC
voltage is present on any of the power components.
2. Disconnect all four wires connected to terminal block 1 (TB1) positions
1-3 on the temperature CT board.
3. Disconnect the 4 red transformer wires on each of the gate drive boards.
These are TB1, positions 3 and 5 for each gate drive board. Typically, a
2300 V unit will have only four wires per phase to disconnect, a 4160 V
unit will have eight wires per phase, a 6900 V unit will have twelve wires
per phase, and a 13.8 kV unit will have 24 wires. A 6900 V/400 A unit will
also have 24 wires.
4. Using a 9/16 in. wrench, carefully unbolt all of the line and load power
connections attached to the heat sinks.
If the unit is a 6900 V or 13.8 kV, remove the power strap
connecting one side of the stack to the stack directly below it.
5. Note the labels on the fiber optic wiring cables to ensure they will be
replaced in the correct socket.
6. Remove all fiber optic connectors on the stack.
7. Gently push on the connector tab and pull with a gentle left-to-right
motion on the connector in the direction away from the fiber optic device.
There are two connectors per gate drive board, and one duplex
connector on the small Temp/CT board on top.
CAUTION
HAZARD OF EQUIPMENT DAMAGE
Do not touch the tip of the connectors or contaminate the connection
sockets with any dust or foreign material.
Failure to follow this instruction can result in equipment
damage.
8. Remove the wires from the Temp/CT board terminal block (3 screws).
9. Using a 9/16 in.socket with a 6 in. extension, remove the lower bolt that
routes through the front face of the heat sink and into the isolation
standoff mounted to the white panel.
10. Carefully hold the heat sink in place with one hand and remove the top
bolt from the heat sink.
11. Ensure the fiber optic connectors and all wires are positioned out of the
way.
12. Remove the heat sink from the unit.

1. Using a properly rated voltage testing device, verify that no DC or AC
voltage is present on any of the power components.
ENGLISH
2. Verify that CPTs are set up for the proper voltage. If using 240 or 480
Vac three-phase, verify that the transformers are strapped for that
voltage. Configure as an open delta for three-phase as shown in
Figure 55 on page 87.
3. Verify that the medium voltage isolation means is open and remove the
medium voltage fuses. For fuse removal procedures, refer to the
appropriate Motorpact Medium Voltage Motor Controllers instruction
bulletin: # 46032-700-06 for NEMA enclosures.
4. Connect 240 or 480 Vac three-phase power to the downstream side of
the fuses. Do not connect to the isolation means side of the fuses. The
small test motor used will determine the required size cable or current.
5. Connect the primaries of the test CPT in the proper phase sequence of
A-B-C.
6. Disconnect the medium voltage motor.
7. Connect the low voltage motor (typically 5 hp or less).
8. Connect a wire jumper between TB8 pins 1 and 2 on the soft start’s
terminal control board (TCB) located in the medium voltage
compartment to bypass the disconnect and blown fuse indicators.
9. Install a (test) switch on TB1 pins 1 and 8 on the soft start TCB to bypass
all interlocks, such as stop-start signals.
10. Verify or wire a 120 Vac plug to the test plug supplied by the factory (line
start packages only).
11. Remove both control power fuses on the medium voltage CPT.
12. Remove all three fuses from the medium voltage potential transformer
(PT).
13. Verify that the 120 V test switch is in the “NORMAL” position (line start
package only).
14. Connect test power to the test plug connector and place the 120 V test
switch in the “TEST” position.
15. The keypad should be energized with the “Power LED,” Stop LED.
16. Close the temporary Start switch, which is connected to the control
board.
17. The main vacuum contactor should close and the keypad should trip on
“Under Voltage.” Open the temporary test switch and reset the CPU
fault.
18. Connect the secondary of the test PT to panel TB1 on the main firing
board as follows (see Figure 55 on page 87):
— position 1 - phase A
— position 3 - phase B
— position 5 - phase C
The main firing board is located behind the low voltage compartment
door.
19. Verify that all connections are good. Energize the low voltage of either
240 or 480 V, three phases.
20. Use the multimeter on the AC scale and verify three-phase 120 Vac
(phase to phase) at TB1 pins 1, 3, and 5 on the main firing board.
21. If all 120 Vac three-phase is present, de-energize the low voltage of 240
or 480 Vac.
22. Re-energize the low voltage of 240 or 480 Vac.

23. All test voltages should be 240 or 480 Vac, three-phase 120 Vac (test
PT), and 120 Vac single phase for control power.
24. Close the temporary Start switch and the test motor should start
smoothly.
25. Use the multimeter on the AC scale and check (phase to phase)
voltages on T1, T2, and T3 motor leads. The voltages should be
balanced.
26. If the motor does not start smoothly, the soft starter is not functioning
properly. See “Low Voltage Troubleshooting” on page 79.
27. If the motor starts and runs smoothly, repeat the steps of this procedure
in reverse to restore the starter to operating condition.
