1.4 Design Features
The standard JKSSS+ configuration is a complete NEMA Class E-2 motor controller which includes the following features:
� Isolation Switch: An isolation switch is provided in the incoming power section of the starter assembly. The maximum voltage is 7200V.
Power is switched on and off to the controller by a fixed-mounted, externally-operated, three-pole isolation switch. When the switch is in the opened position, incoming power is isolated from the controller compartment interior by an automatic shutter. For additional safety, the load terminals of the switch are automatically grounded when the switch is opened. This allows any stored energy in the controller load circuit to be discharged by closing the contactor using test power.
A viewing window in the Main Incoming Power Compartment allows visual inspection of the disconnect blade status with the medium voltage door closed.
The external operating handle for the isolation switch is designed to accept up to three external padlocks in the OFF position.
For additional information on the isolation switch, see instruction manual VF010H01, VF010H02 or VF010H03.
� Power Fuses: As a NEMA Class E2 controller, current limiting primary power fuses are provided for each incoming phase.
Typically the fuses are ANSI class "R" for units rated up to 5000V. The fuses are sized according to motor locked rotor current and are coordinated with the solid state overload relay. The fuse and overload coordination is designed to allow the controller and contactor to clear low and medium level faults. This prevents exceeding the contactor interrupt ratings. Fuses interrupt high level faults that exceed the contactor interrupt ratings.
� SCR Power Modules: For each phase, the SCRs are arranged in inverse parallel pairs and series strings as indicated in Table1 below to facilitate sufficient Peak Inverse Voltage ratings for the application.
� RC Snubber Networks: Provide Transient Voltage Protection for SCR Power Modules in each phase to avoid dv/dt damage.
� Firing Circuit: The SCRs are gated (turned on) using a Sustained Pulse Firing Circuit. This circuitry is isolated from the control voltage by means of fiber optics.

� Enclosure Finish: The enclosure is suitable for use in noncorrosive environments. The paint is ANSI 61 gray polyurethane powder over a zinc phosphate pretreatment with a minimum thickness of 2 mil. 11 gauge steel is used in all enclosures. All NEMA 1 & 12 units have bottom entrance plates.
� Lifting Provisions: Eyes or angles capable of supporting the maximum weight of each shipping split are provided on the top of the enclosure.
� Power Bus: Optional main horizontal phase bus bars can be configured to extend the entire length of the starter lineup. Bus bar material is tin-plated or silver-plated copper. All bus ratings are per UL Standard 347.
� Bracing: Bus bars are braced with non-tracking fire resistant non-hygroscopic insulation supports and have a minimum fault current rating of 50,000 Amps.
� Connections: All bus connections use 2 bolts minimum, with Belleville spring washers to ensure tightness. Splice kits for each shipping split are included, along with specific installation instructions.
� Ground Bus: A continuous ground bus bar with a minimum rating of 400 Amps extends the entire length of the starter near the bottom of each enclosure. A grounding strap connects each vertically adjacent compartment and also ties the grounding arm of the disconnect switch to the main ground bus bar (see section 2.8).
� Seismic Qualifications: The entire starter assembly, when properly installed, withstands vertical and horizontal accelerations typical of seismic Zones 1 through 4 as defined in the UBC. The assembly will not overturn or show significant lateral movement, but cannot be expected to continue operating during, or after, a seismic event.
1.5 Theory of Operation
The soft starter is CPU controlled, using a microprocessor based protection and control system for the motor and starter assembly. The CPU uses Phase Angle Firing control of the SCRs to apply a reduced voltage to the motor, and then slowly and gently increases torque using voltage and current control until the motor accelerates to full speed. This starting method lowers the starting current of the motor, reducing electrical stresses on the power system and motor. It also reduces peak starting torque stresses on both the motor and load mechanical components, promoting longer service life and less downtime.
1.5.1 Acceleration: The soft starter comes standard with several methods of accelerating the motor so that it can be programmed to match almost any industrial AC motor application. The factory default setting applies a Voltage Ramp with Current Limit as this has been proven to be 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 (Ramp Time setting) until one of three things happen: 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 full voltage will be applied. This will prevent any surging or pulsation in the motor torque, which might otherwise occur due to the load not being fully coupled to the motor when operating at reduced voltage and torque levels. 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 provide protection against a stall condition, an overload condition, or excessive acceleration time.
The Current Limit feature is provided to accommodate installations where there is limited power available (for example, on-site generator power or utility lines with limited capacity). The torque is increased until the motor current reaches the pre-set Current Limit point and it is then held at that level. Current Limit overrides the ramp time setting so 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 starter detects an At-Speed condition and closes the Bypass Contactor. The Bypass Contactor serves to shunt power around the SCR stack assemblies to prevent heat build-up in the starter enclosure due to the slight voltage drop across the SCRs. At this point, the motor is operating at full voltage, speed and power.

Other starting methods available in the soft starter are: � Current Ramp uses a closed current feedback PID loop to provide a linear torque increase up to a Maximum Current level. � Constant Current is immediately increased to the Current Limit point and held there until the motor reaches full speed. � Power (kW) Ramp uses True RMS kW feedback PID loop to provide a linear increase in True RMS motor power to a maximum set kW value. � Custom Curve gives the user the ability to plot torque and time points on a graph. The soft starter will then accelerate the motor following these points. � Tachometer Feedback Ramp uses a closed loop speed follower method monitoring a tachometer input signal from the motor or load shaft to provide a linear RPM acceleration.

1.5.2 Deceleration: the soft starter provides the user with the option of 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 in that 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 where a controlled
stop prevents water hammer and mechanical damage to the system.

1.6 General Protection
The soft starter is provided with a built-in motor protection relay that can be programmed for primary protection of the motor / load system. Operation of the soft starter can be divided into 4 modes: Ready, Start, Run and Stop.
1.6.1. Ready Mode: In this mode, control and line power are applied and the starter is ready for a start command. Protection during this mode includes the monitoring of current for leakage through multiple shorted SCRs or welded contacts on the Bypass Contactor. Other protection features in effect are: � Starter Power Pole Temperature � Shorted SCR � Blown Fuse Indication � Phase Reversal (if enabled) � Line Frequency Trip Window � External Input Faults � Undervoltage � Overvoltage
Note: The "Programming Mode" can only be entered from the Ready Mode. Any attempt to enter data while the motor is starting or running will be blocked. During programming, all protection features and start command are disabled.
1.6.2 Start Mode: These additional protection functions are enabled when the soft starter receives a valid Start command: � Phase Reversal (if enabled) � Phase Reversal will still be on and is not a newly active feature when starting. � Start Curve � Acceleration Timer � Phase Imbalance � Short Circuit / Load Pre-check (Toe-in-the-Water) � Ground Fault (Optional) � External Input Faults � Accumulated Starting FLA Units (I2t Protection) � Starting Overload Protection Curve Selection � Thermal Capacity
Note: Shorted SCR protection is no longer in effect once the soft starter goes into the Start Mode.

JKSSS Series Solid State Soft Starters

1.6.3 Run Mode: The soft starter 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: � Running Overload Curve � Phase Loss � Under Current / Load Loss � Over Current / Electronic Shear Pin (Jam Protection) � External Input Faults .
1.6.4 Stop Mode: Once a Stop command has been given, the protection features change depending on which Stop Mode is selected. � Decel Mode: Retains all protection features of the Run Mode. At the end of Decel, the motor will be stopped and the protection features change as indicated below. � Coast-To-Stop Mode: Power is immediately removed from the motor and the soft starter returns to the Ready Mode. � Additional protection features activated when the stop command is given include: - Coast-Down / Back Spin Timer - Starts-per-Hour - Time between Starts - External Input Faults
1.7 Thermal Overload Protection
The soft starter plays an important role in the protection of your motor in that it monitors the motor for excessive thermal conditions due to starting, running and ambient conditions. The soft starter has a Dynamic Thermal Register system in the CPU that provides a mathematical representation of the thermal state of the motor. This thermal state information is retained in memory and is monitored for excesses in both value and rate of change. Input is derived from current imbalances and RTD measurements making it dynamic to all processes involving the motor. The Soft Starter monitors these conditions separately during the Start and Run modes to provide proper thermal overload protection at all times.
1.7.1 Start Mode overload protection is selectable using one of three methods: � Basic Protection: I2t data is accumulated and plotted based on an Overload Curve selected in programming. This 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 Starter. � 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 for the soft starter to follow. � Learned Curve Protection: The user sets the soft starter 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 starter is then switched to Curve Follow protection mode and monitors motor performance against this curve. This feature is especially useful in initial commissioning tests to record a base line performance sample (in this case, it is not necessarily used for motor protection).
1.7.2 Run Mode overload protection is initiated when the soft starter determines that the motor is At-Speed. Overload Protection is initiated 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 motors that are off-line (such as after a trip) since cooling fans are also inoperative. � RTD Input will bias the register in either direction based on real-time input of the motor, bearing and even ambient temperature conditions. � Dynamic Reset is another feature that adds reliability and consistency to the performance of the soft starter. If a

7 TOSHIBA

Basic Installation and Operation Guide

JKSSS Series Solid State Soft Starters

motor overload condition occurs and the Overload protection trips, it cannot be reset until sufficient cool down time has elapsed. This cool down time is determined by the "Learned Thermal Capacity" required to start the motor which must be regained before the overload can be reset. This ensures sufficient thermal capacity for a successful restart of motor. � Retentive Memory provides continuous overload protection and true thermal modeling by means of a running back up of the thermal register even if power is lost. Upon restoration of power, the soft starter will read the Real Time Clock, then recalculate and restore the thermal register to what it should be, given the elapsed time and the cool down rate of the motor. � Learned Reset Capacity is a feature that is unique to the soft starter. By sampling the amount of thermal capacity used in the previous three successful starts, the starter will not allow a reset until a sufficient amount of thermal capacity has been regained in the motor. This prevents nuisance tripping and insures that unsuccessful start attempts (which would otherwise use up the starts-per-hour capacity of the motor) are not counted.

1.8 Firing Circuit
The SCR gate firing circuit is critical to the performance and stability of the system. The firing circuit includes several
unique features which enhance the ruggedness, noise immunity and flexibility for maximized performance. In most applications, this performance is attained without the need for reactors or field installed devices. These features
include: � Auto Synchronizing of the gate timing pulses match each phase firing angle to their respective phases. The soft
starter actively tracks minor shifts in the line frequency avoiding nuisance tripping that may happen with
conventional gate firing systems. This is especially useful on portable or backup generator supplies, allowing the soft starter to be used confidently in applications that have unstable power. � 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. This provides the soft starter with superior noise immunity and
protects against misfiring, enhancing the soft starter stability. � Closed Loop Firing Control is a method of balancing the SCR firing pattern. The CPU uses feedback signals
from both the output current and voltage providing smooth output and preventing imbalances during ramping which prevents unnecessary motor heating. � Transformer Isolation of SCR firing information and signals prevents interference from line noise and EMI/RFI that may be present. Three phase isolation transformers provide potential measurement, firing board timing while
Providing isolation from the line voltage. High isolation Ring Transformers are used to step the 120V control
voltage down to 28VAC for the Sustained Pulse firing circuit, providing further isolation for the SCR gates. � Fiber Optic Isolation is provided for all gate drive and current feedback signal interfaces between the Medium
Voltage and Low Voltage systems.

Electrical Checks

With incoming power isolated and all loads disconnected electrically, the control circuit and other mechanisms should be exercised to determine that the devices operate properly. An auxiliary source of control power will be necessary to provide power to the electrical operators.

WARNING

Electrical shock hazard. Do not touch energized components during a test using auxiliary power.

The ground fault protection system (if furnished) should be tested in accordance with the instructions furnished with the device.

An electrical insulation test should be performed to ensure that the controller and associated field wiring are free from short circuits and grounds. The preferred method is to perform a dielectric test at 2.25 times the nominal system voltage plus 2000 volts. This should be done phase-to-ground, phase-to-phase and phase-to-neutral (if applicable), with all switches and circuit breakers opened. Disconnect any devices which may have limited dielectric strength and that are not intended for this test.

The light or buzzer, or both, used to indicate breakdown should be calibrated to indicate failure with an output current between 1.5 and 2.0 milliamperes per 1000 volts applied.

WARNING

Hazardous voltages are present during dielectric testing that can result in serious injury or death. High potential test should be performed only by qualified personnel. Refer to safety instructions provided with the test equipment.

All devices must be set to their normal or OFF position before energizing incoming power.

Incoming Line On the standard JKSSS, incoming power cable connections should be made at the points shown on the wiring diagram furnished with the equipment.
Note: Proper phase sequence must be observed when connecting the input power. For example, phase A must lead phase B, which in turn must lead phase C by 120� respectively. If the phase rotation is not correct, a fault light and the OLED display will indicate the problem. The SCR output will be clamped.
Load Connections The load cables should be routed through the wireways furnished within the enclosure. For load cable termination arrangements, refer to the drawings furnished with the equipment.
Ground Connections The controller line-up must be grounded in accordance with the requirements of the National Electrical Code. Proper equipment grounding must be established before making any incoming power connection. If a main ground bus is furnished, make the ground connection to this bus. If there is no ground bus, the sections which are shipped separately should be connected in such a way as to ensure a continuous grounding path.
Each section contains a vertical ground bus extending from the main ground bus or ground pad to each controller compartment.
Special attention should be paid to protection for operating personnel, to protection of equipment itself, (e.g. such as ground fault relays) and protection of sensitive transducers or control devices that are electronic in nature.
The following may be used as a general guide with regard to equipment grounding.
Controller used as service equipment for a grounded system or as a main section for a separately derived system:
a. The grounding electrode conductor (ground wire) sized in accordance with NEC 250 should be run from the grounding electrode to the controller ground bus or ground terminal.
b. Unless already done at the factory, a main bonding jumper should be installed from the incoming grounded connector bus (neutral) to the ground bus or designated grounding point. If a jumper is not furnished, one having a size in accordance with NEC 250 should be selected.
c. Steps (a) and (b) should effectively connect together the grounding electrode, the controller frame, all outgoing equipment grounding conductors and the grounded neutral bus of the system.
d. No connection should be made to ground on the load side of any neutral disconnecting line or any sensor used for ground fault protection. No connections should be made between outgoing grounding connectors and the neutral.
e. Where the controller or system is dual-fed (double-ended) and has ground fault protection, special precautions are necessary to accomplish proper grounding and bonding.
Controller used as service equipment for an ungrounded system or as a main section for a separately derived system:
a. A grounding electrode conductor (ground wire) sized in accordance with NEC 250 should be run from the grounding electrode to the controller ground bus or ground terminal.

Basic Installation and Operation Guide

JKSSS Series Solid State Soft Starters

b. If the system is grounded at any point ahead of the controller, the grounded conductor should be run to the controller in accordance with NEC 250 and connected to the ground bus or ground terminal.

c. Steps (a) and (b) should effectively connect together the grounding electrode, the controller frame, all outgoing equipment grounding connectors and any grounded conductor which runs to the controller.

Controller not used as service equipment or as a main section for a separately derived system, and used on either a grounded or ungrounded system:

a. The controller frame and any ground bus should be grounded by means of equipment grounding conductors having a size in accordance with NEC 250 and run with the main supply conductors or by bonding to the raceway enclosing the main supply conductors in accordance with NEC 250.

b. Ground leads should be connected to cable potheads/ shields as specified by the manufacturer of these devices.

Chapter 3 - Start-up
3.1 Introduction
It is best to operate the motor at its full load starting condition to achieve the proper time, torque and ramp settings. Initial settings are set to accommodate most motor conditions. TRY INITIAL SETTINGS FIRST. See Section 5.1.2 Starter Configuration (Setpoint Page 2) to make any adjustments.
3.2 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. Adjustment description and procedures are described as follows. See Section 5.1.2 Starter Configuration (Setpoint Page 2) for additional Accel settings.
3.2.1 Initial Voltage Factory Setting = 20% of line voltage Range = 0% - 100% of line voltage Initial voltage adjustment changes the initial starting voltage level to the motor.
3.2.2 Ramp Time Factory Setting = 10 sec. Range = 0 - 120 sec. Ramp time adjustment changes the amount of time it takes to reach the current limit point or full voltage if the current limit point was not reached.
Note: Refer to your motor manual for the maximum number of starts per hour allowed by the manufacturer and do not exceed the recommended number.
3.2.3 Current Limit (FIG. 3.2.3 below) Factory Setting = 350% of motor FLA Range = 200% - 500% of motor FLA The main function of current limit is to limit the maximum current. It may also be used to extend the ramp time if required. The interaction between the voltage ramp and the current limit will allow the soft start to ramp the motor until the maximum current is reached and the current limit will hold the current at that level. The current limit must be se high enough to allow the motor to reach full speed. The factory setting of 350% is a good starting point.
Do not set the current limit too low on variable starting loads. This could cause the motor to stall and eventually cause the overload protection to trip.
Note: If the motor does stall, refer to the motor manufacturer's motor data for the proper cooling time.

3.3 Deceleration Adjustments (Pump Control)
Decel control extends the stopping time on loads that would otherwise stop too quickly if allowed to coast to stop. Decel control provides smooth deceleration until the load comes to a stop. Three adjustments optimize the deceleration curve to meet the most demanding requirements. The unit is shipped from the factory with the Decel control feature disabled.
3.3.1 Deceleration Applications Apply power and adjust the soft start before enabling or modifying the deceleration adjustments. Both, acceleration and deceleration adjustments should be made under normal load conditions. The deceleration feature provides a slow decrease in the output voltage, accomplishing a gentle decrease in motor torque during the stopping mode. This is the OPPOSITE OF BRAKING in that, it will take longer to come to a stop than if the starter were just turned off. The primary use of this function is to reduce the sudden changes in pressure that are associated with "Water Hammer" and slamming of check valves with centrifugal pumps. Decel control in pump applications is often referred to as Pump Control. In a pump system, liquid is being pushed uphill. The force exerted by gravity on the column of liquid as it goes up hill is called the "Head Pressure" in the system. The pump is sized to provide enough Output Pressure to overcome the Head Pressure and move the fluid up the pipe. When the pump is turned off, the Output Pressure rapidly drops to zero and the Head Pressure takes over to send the fluid back down the hill. A "Check Valve" is normally 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 check valve slams closed. Since fluids can't compress, that energy is transformed into a "Shock Wave" that travels through the piping system looking for an outlet in which to dissipate. The sound of that shock wave is referred to as "Water Hammer" and the energy in that shock wave can be extremely damaging to pipes, fittings, flanges, seals and mounting systems.
By using the Soft Stop/Deceleration feature of the soft starter, the pump output torque is gradually and gently reduced, which slowly reduces the 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 the Shock Wave is avoided. When the output voltage to the motor is low enough to no longer be needed, the soft starter will end the Decel cycle and turn itself off. (See FIG. 3.3)

FIG. 3.3 Deceleration Control
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 of the Bridge or Trolley can prevent loads from beginning to over swing on sudden stops.

3.3.2 Start Deceleration Voltage Factory Setting = 60% of line voltage Range = 0% - 100% of line voltage The step down voltage adjustment eliminates the dead band in the deceleration mode that is experienced while
the voltage drops to a level where the motor deceleration is responsive to decreased voltage. This feature allows
for an instantaneous drop in voltage when deceleration is initiated.

3.3.2 Stop Deceleration Voltage Factory Setting = 30% of line voltage Range = 0% - 100% of line voltage The stop voltage level setpoint is where the deceleration voltage drops to zero.
3.3.3 Deceleration Time Factory Setting = 5 sec. Range = 0 - 60 sec. The deceleration ramp time adjusts the time it takes to reach the stop voltage level setpoint. The unit should be restarted and stopped to verify that the desired deceleration time has been achieved. When calculating the number of starts per hour, a decel curve should be counted as a start curve. For example, recommended number of starts per hour = 6, allowable starts with decel cycle per hour = 3. Note: Do not exceed the motor manufacturer's recommended number of starts per hour.
3.4 Sequence of Normal Operation
It is best to operate the motor at its full load starting condition to achieve the proper time, torque and ramp settings. Initial settings are set to accommodate most motor conditions.
TRY INITIAL SETTINGS FIRST FOR: - Initial Voltage - Current Limit - Ramp Time
See Section 5.1.2 Setpoint Page 2 to make any adjustments. If the Decel function is enabled, related parameters may also need adjusting to achieve optimal Decel performance
Sequence:
� Close the disconnect switch to apply 3 phase power" Verify the power LED on the keypad comes on.

MOTOR STOPPED READY TO START

� Activate the start command, the motor should start accelerating and the RUN LED will come ON.

Check: If the motor decelerates, or stops, during the acceleration period, activate the Stop button immediately. Adjustments to the ramp time and or current limit setting are necessary to provide the motor sufficient energy to reach full speed. If the unit does not follow this operational sequence, please refer to the Troubleshooting Chapter.
If the motor does not enter the run mode in the set time (Acceleration time limit, see SP8.2), a trip will occur. When the Motor Reaches full speed, the At Speed" LED will come on and Aux 4 (At Speed) relay will energize closing the bypass contactor. Phase A, B, C and Ground Fault current is then shown on the keypad during operation.

3.5 Emergency Bypass Operation

Emergency Bypass
� Remove input power by opening the disconnect switch and lock out. � Close the emergency Bypass contact located on the TCB board at TB2
(See section 2.2.1 for location). � Unlock and reclose the disconnect switch.
Note: In the emergency bypass mode, there is no overload protection unless a separate (optional or customer supplier) thermal overload relay is installed, or JP-1 (Motor Protection Jumper, Sec. 2.9.3) is removed from the TCB Board.

DANGER
HAZARDOUS OPERATION Do not operate the Bypass Contactor with medium voltage power applied to the unit. Failure to follow this instruction will cause the motor to start unexpectedly.

The unit is operable as a normal across-the-line starter. When power is applied, the bypass contactor is energized, tying the input terminals directly to the output terminals. When the "START" command is given, the main (in-line) contactor is energized and the motor starts. When the "STOP" command is given, the motor is disconnected from the line via the main (in-line) vacuum contactor.

JKSSS Series Solid State Soft Starters

SP2.1 Start Control Mode: Dual Ramp, Custom Accel Curve, Jog Voltage, Start Ramp 1, Start Ramp 2. � Dual Ramp: The dual ramp mode works in conjunction with External Input #3. This allows the user to switch between the two start ramps without having to reconfigure the start mode (for details on configuring External Input
#3 for DUAL RAMP, see Setpoint Page 6). � Custom Accel Curve: Allows the user to custom design the acceleration start curve to the application (see
setpoint page 7 for configuration setup). Note: If Custom Accel Curve has not been enabled in Setpoint page 7, the soft starter will ignore the start control
mode and read this setpoint as disabled.

SP2.2 Jog Voltage: The voltage level necessary to cause the motor to slowly rotate.

SP2.3 Start Ramp 1 Type: The ramp type can be setup for either Voltage or Current. If Voltage is selected, initial voltage, ramp time and current limit are adjustable. If Current is selected, initial current, ramp time and maximum current are adjustable. Start Ramp 1 Type: Voltage � Voltage Ramping is the most reliable starting method, because the starter will eventually reach an output voltage high enough to draw full current and develop full torque. This method is useful for applications where the load conditions change frequently and where different levels of torque are required. Typical applications include material handling conveyors, positive displacement pumps and drum mixers. 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 CURRENT LIMIT #1 setpoint to 500% (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.

FIG. SP2.3 Example of Switching from Jog to Start Ramp #1 Type: Voltage

� Voltage Ramping with Current Limit is the most used curve and is similar to voltage ramping; however, it adds an adjustable maximum current output. Voltage is increased gradually until the setting of the Maximum Current Limit setpoint is reached. The output is held at this level until the motor accelerates to full speed. This may be necessary in applications where the electrical power is limited. Typical applications include portable or emergency generator supplies, utility power near the end of a transmission line and utility starting power demand restrictions.

Note: Current Limit will override the Ramp Time setting if necessary, so use this when acceleration time is not critical.

To set Voltage Ramping with Current Limit, select VOLTAGE for the START RAMP #1 setpoint and set CURRENT LIMIT #1 setpoint to a desired lower setting, as determined by your application requirements.

Start Ramp 1 Type: Current � Current Ramping (Closed Loop Torque Ramping) is used for smooth linear acceleration of output torque. This ramp is only used on some conveyor systems (long haul or downhill). For other applications, use Voltage Ramp or a custom Accel curve. Output voltage is constantly updated to provide the linear current ramp, and therefore the available torque is maximized at any given speed. This is for applications where rapid changes in torque may result in load damage or equipment changes. Typical applications include overland conveyors if belt stretching occurs, fans and mixers if blade warping is a problem, and material handling systems if stacked products fall over or break. Cont.

Basic Installation and Operation Guide

JKSSS Series Solid State Soft Starters

This feature can be used with or without the Maximum Current Limit setting. To achieve Current Ramping select CURRENT for START RAMP #1 TYPE setpoint and set the MAXIMUM CURRENT #1 setpoint to the desired level.
� Current Limit Only (Current Step) uses the Current Limit feature exclusively. This method of starting 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, setpoint RAMP TIME #1 is set to minimum so that the output current jumps to the current limit setting immediately. Typically used with a limited power supply when starting a difficult load such as a centrifuge or a deep well pump, when the motor capacity is barely adequate (stall condition or overloading occurs) or if other starting modes fail. Since ramp times are set to minimum, START RAMP #1 TYPE is set to either VOLTAGE or CURRENT.
� Initial Torque (Initial Voltage #1 or Initial Current #1) sets the initial start point of either Voltage Ramp or the Current Ramp. Every load requires some amount of torque to start from a standstill. It is inefficient to begin ramping the motor from zero every time, since between zero and the WK2 break-away torque level, no work is being performed. The initial torque level should be set 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.
� Ramp Time #1 sets the maximum allowable time for ramping the initial voltage, current (torque) or power setting to either of the following: - The Current Limit setting when the motor is still accelerating. - Full output voltage if the Current Limit is set to maximum. - KW if Power Ramp is selected. Increasing the ramp time softens the start process by gradually increasing the voltage, current or power. Ideally, the ramp time should be set for the longest amount of time the application will allow (without stalling the motor). Some applications require a short ramp time due to the mechanics of the system. (i.e., centrifugal pumps, because pump problems can occur due to insufficient torque).
� Current Limit sets the maximum motor current the starter will allow during the acceleration. As the motor begins to ramp, the Current Limit feature sets a maximum at which the current draw is held. Current Limit remains in effect until the following occurs: 1) The motor reaches full speed (Detected by the At-Speed detection circuit) or; 2) The Overload Protection trips on Motor Thermal Overload. Once the motor reaches full speed, the Current Limit feature becomes inactive. In the Voltage Ramp Profile, the voltage output is increased until it reaches the Current Limit. Ramp time is the maximum amount of time it takes for the voltage to increase until the Current Limit setting takes over. With some load conditions, the Current Limit is reached before the Ramp Time expires. The Current Ramp profile varies the output voltage to provide a linear increase in current up to the Maximum Current setpoint value. A closed loop feedback of motor current maintains the Current Ramp profile.
SP2.4 Start Ramp 2 Type: Please refer to Ramp 1 settings for Ramp 2 Type: Voltage selection.
Start Ramp 2: Power
! CAUTION
Do not use on an unloaded un-coupled motor!
The power ramp should only be used with a loaded motor.
� The Power Ramp feature has three programmable setpoints, Initial Power, Ramp Time and Maximum Power. - The Initial Power setpoint allows the user to define an initial KW (motor power) value that will be applied to the motor when the start sequence is begun. It has a range of 0-100% and a default value of 20%. - The Ramp Time functions as all other ramp time and allows the user to define a time period during which the applied KW (motor power) will be increased linearly to the Maximum Power value setpoint. The adjustment range is 1-120 seconds. Once the Power Limit value is reached, the system enters a constant power mode that regulates the applied motor power until the motor reaches full speed. - The Maximum Power setpoint has an adjustment range of 0-300% and a default value of 80%.

� Power Ramp Calculations: The basic motor power value is derived from the line voltage and motor FLA, using a unity power factor as a default. This allows for approximation of the motor power rating without any other input data. During the Power Ramp process, the RMS line voltage, RMS motor current and power factor are measured on a cycle by cycle basis and applied to the Power Ramp algorithm. The CPU then calculates the True RMS motor power and will control the SCR firing to deliver the programmed power ramp values to the motor.

Maximum Power

Initial Power

t Power Ramp

- Initial Power: The Initial power setpoint allows the user to define an initial KW (motor power) value that will be applied to the motor at the beginning of the start sequence.
- Ramp Time #2: See Ramp Time #1 for description. - Maximum Power: Sets the maximum motor power the starter will allow during the acceleration. As the motor
begins to ramp, the "Maximum Power" sets a limit.
SP2.5 Kick Start: Used as an initial energy burst in applications with high friction loads.
� Kick Start Voltage: The initial voltage (as a percent of full voltage value) that is needed to start the motor (e.g. Breakaway or Initial Torque).
� Kick Start Time: The time the initial torque boost is applied.
SP2.6 Deceleration: Allows the motor to gradually come to a soft stop.
� Start Deceleration Voltage: Upon receiving a STOP command, the output voltage initially drops to this voltage (represented as a percent of voltage value).
� Stop Deceleration Voltage: The drop-off point of the deceleration ramp (percent of voltage value). The point at which the unit output drops to zero to end the deceleration.
� Deceleration Time: The time to get to the stop Deceleration Voltage setpoint value.
SP2.7 Timed Output: Used with an AUX (5-8) relay. When enabled, and upon a start command, it waits until the programmed time plus the run delayed time has expired. The relay energizes and remains so until a stop command is received. It de-energizes upon receiving a stop command.
SP2.8 Run Delay Time: Can be used with an AUX (5-8) relay. The delay timer begins upon receipt of the start command. The relay will then drop out when the time has expired.
SP2.9 At-Speed Delay Time: Used with the AUX 4 relay, it energizes when the motor reaches At-Speed and the Programmed delay time has expired. The relay remains energized until a stop command has been received.
SP2.10 Bypass Pull-in Current: Level is a % of Motor FLA at which the bypass activates while at speed.

Page 5 Relay Configuration
Option: Yes or No

TRIP (AUX1) RELAY FAIL-SAFE: NO

SP5.1 When a relay has been configured as fail-safe and power is applied, the relay will be energized. The relay will then de-energize when an event occurs or if the power fails.
NOTE: The relays in the soft starter will not prevent a start sequence unless they are wired in as interlocks. If power is lost, the motor power is also lost. Do not change the programming for AUX 1-4. These are for factory use only. AUX 5-8 are user defined outputs.

ALARM (AUX2) RELAY FAIL-SAFE: NO
AUX 3 RELAY FAIL-SAFE: NO
AUX4 RELAY FAIL-SAFE: NO
AUX5 RELAY FAIL-SAFE: NO

SP5.2 A relay configured as non-latching will reset itself when the cause of the trip event is not continuous. The TRIP (AUX1) relay should always be programmed for latching, because this trip should require a visual inspection of the motor and starter before issuing a manual reset to release the relay after a trip has been stored.

(Security Level 2)
The soft starter can be configured to accept a tachometer feedback signal using the 4-20mA input.
SP6.1 The first screen of Setpoint page 6 is TACHOMETER SCALE SELECTION. When this is set to ENABLED, the user will need to input the tachometer scale of the 4-20mA input range.
� Manual Tach Scale 4.0 mA: The unit is looking for an RPM value to assign to the lowest point on the scale. This Value should represent the motor at zero speed.
� Manual Tach Scale 20.0 mA: The unit is looking for an RPM value to assign to the highest point on the scale. This value should represent the motor at full speed.
SP6.2 Tach Accel Trip Mode Select: When enabled, the underspeed or overspeed must be selected for the Tach Accel Trip. If underspeed is selected, only the Tach Underspeed Trip Point will be used. If overspeed is selected, only the Tach Overspeed Trip Point will be used.
� Tach Ramp Time: This is the duration of time before the starter begins sampling the tachometer.
� Tach Underspeed Trip: Defines the minimum motor speed using the Tach feedback. When the underspeed trip mode is enabled and the motor speed falls below this level for the time specified by the Tach Accel Trip Delay, an underspeed trip occurs.
� Tach Overspeed Trip: Defines the maximum allowed motor speed using the Tach feedback. When the overspeed trip mode is enabled and the motor speed exceeds this level for the time specified by the Tach Accel Trip Delay, an overspeed trip occurs.
� Tach Accel Trip Delay: The duration of time that the Tach Accel trip condition must persist before a trip is generated.
SP6.3 The controller provides two 4-20mA analog outputs. Each analog output is independent of the other and can be assigned to monitor different functions. The available output ranges are RPM, Hottest Non-Stator (Bearing) RTD, Hottest Stator RTD, RMS current, and % of Motor Load.
� Analog Output #1 � Select a function from the available five options to be transmitted from the 4-20mA output.
Note: If selecting RPM, the Tachometer feedback input signal must be present in order for the controller to give proper output. If selecting RTD, an RTD input signal must be present for a proper output to be given from the analog output.
� Analog Output #1 (4 mA): Enter a value that the 4mA level will represent for the selected function; typically this value should be 0.
� Analog Output #1 (20 mA): Enter a value that the 20mA level will represent for the selected function.
SP6.4 Analog Output #2 � All of the setpoints and setup screens for Analog Output #2 are the same as those for Analog Output #1.

SP8.2 Basic Start Overload Curve
� Start Curve Locked Rotor Time: The locked rotor time can be set to the OL Class default chosen in Setpoint Page 1 or to a specific time. The overload condition must exist for the programmed amount of time before a trip occurs.
� Start Locked Rotor Current: The current the motor draws with full voltage on the windings and no motor movement (as a percent of motor FLA). Refer to the motor nameplate data or contact the motor manufacturer.
� Acceleration Time Limit: If the motor does not enter run mode (reach "At-Speed") within the pre-set time, the unit trips on acceleration time limit.
� Number of Starts per hour: If enabled, this limits the maximum number of starts permitted per hour. This setpoint allows a maximum of 6 starts per hour. Contact the motor manufacturer for further information regarding number of starts per hour.
� Time Between Starts: If enabled, the soft starter prevents another start attempt until the programmed time has expired.
SP8.3 Area Under Curve Protection: If enabled, this secondary start protection uses both the basic start protection and the area under the curve protection.
� Max I*I*T Start: The maximum I�t allowed during start. If the I�t to start exceeds this number then the soft starter will generate a trip.
SP8.4 Current Over Curve: Learns the motor's starting characteristics and protects the motor based upon the learned curve. It is useful when commissioning a new motor.
� Learn: The unit reads the motor's starting characteristics. Start the motor and allow it to come to full speed. The start feedback enables the motor protection based on the learned start curve.
� Learned Start Curve Bias: The maximum allowed deviation above or below the start curve before a trip is generated.
� Time for sampling: The time the soft starter continues to sample the start curve characteristic during learn mode.

SP.9 RTD Configuration (Setpoint Page 9) (Security Level 3)

The soft starter has a card that provides 12 programmable RTDs which are individually programmable for type. 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.
SP9.1 Use NEMA Temp for RTD Value: When this setpoint is enabled, the soft starter will use the NEMA design insulation class to limit the maximum allowed range of the alarm and trip level. The maximum allowed temperature range is 240� C or (464�F).
SP9.2 Number Of RTD'S Used for Stator: Up to six RTDs can be assigned to monitor the stator of the motor.
SP9.3 RTD Voting: When this is enabled, the Soft Starter will not post a trip until 2 RTD's have exceeded the trip level. This prevents nuisance RTD tripping.
SP9.4 Description: Each of the 12 RTDs is configured in the following manner. The first column is the RTD type, the second column is the RTD description, the third column is the alarm level, and the fourth column is the trip level. The first six RTDs have been pre-programmed with a description name for the STATOR, with two RTDs per phase.
RTDs #1 & #2 have been named STATOR PHASE A1 and A2 respectively. RTDs #3 & 4 are named STATOR PHASE B1 and B2, RTDs #5 & 6 are named STATOR PHASE C1 and C2.
If other description names are required, press the right arrow button from the RTD Type screen to go the RTD description screen. If no alarm or trip level is required these setpoints can be turned off.

(Security Level 3)
SP12.1 Default Display Screen: This Setpoint group allows the user to choose the default screen the Soft Starter displays while the motor is running. Select the metering page number (1-3), then, select the metering screen number. The range varies depending on the selected page. To display a default screen, program the following two Setpoints:
� Metering Data Page#: Range is Page 1 - 3.
� Metering Data Screen#: If Page 1 is selected as the default page, then Screens 1- 10 are available. If Page 2 Screens 1-29 are available. If Page 3 is selected then Screens 1-6 are available. (See Metering Menu, MP.1, for screen number assignment.)
SP12.2 Alarms: Configures the RTD failure alarm and the thermal register alarm.
� RTD Failure Alarm: If enabled, and an RTD shorts or open, an alarm occurs.
� Thermal Register Alarm: Sets a level in the thermal register to generate an alarm when the Thermal Register Capacity Used has exceeded this level.
� Thermal Alarm Delay: The amount of time that the Thermal Register Used must exceed the Setpoint before an alarm condition will occur.
SP12.3 Thermal Register Setup Information: This Setpoint group will configure the thermal register and indicate to the soft starter which inputs to use when thermal modeling.
� Cold Stall Time: Enter the time from the motor manufacturer's specification sheet or use the time defined by the OL Class. This Setpoint is used to define the thermal capacity of the motor.
� Hot Stall Time: Enter the amount of time specified by the motor manufacturer or use half of the time defined by the OL Class.
� Stopped Cool Down Time: The time the motor needs to cool down after it has stopped. Use only the data provided by the motor manufacturer. This Setpoint is used to configure the cooling rate of the thermal register.
� Running Cool Down Time: The amount of time the motor needs to cool down while running. Use only the data provided by the motor manufacturer.
� Relay Measured Cool Rates: When the RTD option is supplied, the Soft Starter can be configured to use the measured cooling rates from the RTDs instead of the programmed settings. This Setpoint should only be enabled when the RTD option is present.
� Thermal Register Minimum: Sets the value in the thermal register which represents a motor running at the nameplate current (with no overheating or negative sequence currents present).
� Motor Design Ambient Temperature: Use the data from the motor manufacturer's specifications. When RTD option is supplied, this Setpoint will be the base point for the RTD biasing of the Thermal Register.
� Motor Design Run Temperature: Use the data from the motor manufacturer's specifications. This Setpoint defines the operating temperature rise of the motor at full load amps or 100% load.
� Motor Stator Max Temperature: This represents the maximum temperature the stator insulation will withstand. The user may choose to use the temperature setting of the insulation class (selected in Setpoint Page 1) or enter a specific maximum temperature. This value should not exceed the stator's insulation temperature. This maximum temperature represents 100% thermal capacity.
� U/B Input to Thermal Register: Always enabled. It allows the soft starter to use the line current imbalance information to bias the Thermal Register.

JKSSS Series Solid State Soft Starters

Chapter 7 - Maintenance and Troubleshooting
The soft starter is designed to be a maintenance-free product; however, as with all electronic equipment, the unit
should be checked periodically for build-up of dirt, moisture or industrial contaminants. These can cause high voltage
arc-over, carbon tracking or prevent proper cooling of the SCR heat sinks. All bolts should be checked annually for proper
tightness using an accurate torque wrench. According to the manufacturer's manual, check the contactor for air gap spacing of the vacuum bottles.
Note: If the unit is installed in a contaminated environment and forced air cooling is used, blower filters must be checked and cleaned regularly to insure proper air flow and cooling of the enclosure.

7.1 Failure Analysis
When a fault occurs, the OLED will display the fault error while the listed LED and AUX Relay will be lit. Please clear
all faults before attempting to restart the unit.

Note: If the problem persists after the required programming changes have been made, and all corrective action has been taken, please contact the factory for assistance.
