Chapter 1 — Overview

General Introduction

The Cutler-Hammer® Intelligent Technologies S811 IT. Soft Starter from Eaton’s electrical business is an electronic, self-contained, panel- or enclosure-mounted motor soft-starting device. It is intended to provide three-phase induction motors with a smooth start, both mechanically and electrically. The S811 Soft Starters utilize six SCRs connected in a full wave power bridge. Varying the SCR conduction period controls the voltage applied to the motor. This in turn controls the torque developed by the motor. After the motor reaches speed, contacts are closed to bypass the SCRs.

The S811 has built-in communications capabilities through Cutler-Hammer QC (Quick Connect) Port. The S811 Soft Starter utilizes a DIM (Digital Interface Module) that allows the user to conﬁgure the device and read system parameters. The DIM includes an easy-to-read LCD display and keypad to scroll through the menus. The DIM allows the user to modify control parameters, enable or disable protections, set communication variables, monitor system parameters such as line voltages and currents and access the fault queue.

The S811 is designed to fulﬁll the industrial service requirements for applications such as Chillers, Pumps and Machine Tools that require less than 85% of the motor’s rated starting torque for worst case starting condition.

IT. S811 Soft Starter User Manual

The S811 meets all relevant speciﬁcations set forth by NEMA ICS 1, ICS 2 and ICS 5, UL 508, IEC 60947-4-2, CE and CSA.

This user manual covers everything you need to know in order to install, set up, operate, troubleshoot and maintain the S811.

However, no publication can take into account every possible situation. If you require further assistance with any aspect of this product, or a particular application, please contact us.

Note: Short circuit protection must be applied on the line side of the soft starter. The S811 can be wired in both line connected and inside-the-delta connected conﬁgurations.

If a line conﬁguration is desired then the three-phase line feeding and the three main motor leads should be connected for normal across-the-line starting as shown in Figure 3-9. For inside-the-delta connected conﬁgurations be sure to consult Figures 3-10, 3-11 and 3-12.

Note: Only soft starters with catalog numbers S811xxxxxD may be connected in an insidethe-delta conﬁguration. Refer to the motor nameplate for correct wiring information. Contact

Eaton if a special motor wiring requirement exists before wiring your starter.

For more information visit: www.EatonElectrical.com

IT. S811 Soft Starter User Manual

By factory default, the S811 is to be connected with an ABC phase rotation on the incoming power wiring. If the motor turns in the incorrect direction upon energization, exchange two phases at the motor terminal box or at the output terminals of the soft starter. Changing the input wiring will cause a voltage phase reversal trip.

If the input phase sequence to the S811 must be ACB, the incoming phase sequence protection will need to be set to ACB. Setting ACB as the incoming phase sequence causes the ABC incoming phase sequence to cause a voltage phase reversal trip.

IMPORTANT: The reversing contactor must never be switched while the soft starter is operating. In order to gain the full beneﬁt of the S811 with a reversing contactor, the S811 needs to be OFF when switching the direction. The soft starter settings must account for catching a motor spinning in the opposite direction upon soft restarts. The time required for slowing the motor to a stop and then ramping up to speed in the opposite direction adds to the overall starting time. This will also impact the overload protection setting.

See the Motor/Application Considerations in Appendix E of this manual for information on typical motor winding conﬁgurations.

Notes:

1. A minimum wire of 14 AWG (2.5 mm2) should be used between the power supply and the 24V DC + and - terminals.

2. See Using an Auxiliary Relay section below if it is desired to use a relay instead of an indicating lamp for terminals 13, 14, 95, 96 and 98.

3. If an isolation or reversing contactor is used upstream of the S811, Eaton recommends that the user choose the level sensing option.

24V DC Control Power Supply

The S811 Soft Starter requires 24V DC control power. The sealed in and inrush characteristics of the S811 Soft Starter are summarized in Table 3-6:

Table 3-6: 24V DC Power Supply Requirements

Soft Starter Frame

November 2006

For applications where one starter is used with one power supply, the power supply selected must be equal to or greater than both the sealed in and inrush requirements of the starter.

● Max Steady State for the Power Supply ≥ Sealed In Power of the Starter

● Outrush for the Power Supply ≥ Inrush Power of the Starter

Multiple starters can be used with one power supply. If the application requires the starters to start at the same time, the power supply must be sized for the sum of the sealed in and inrush power for each starter.

● Max Steady State for the Power Supply ≥ Sum of the Sealed In Power of all the Starters

● Outrush for the Power Supply ≥ Sum of the Inrush Power of all the Starters

Multiple starters are typically not commanded to start at the same time. If the application requires the starters not be commanded to start at the same time (>150 ms between start commands), the required power is the sum of the largest inrush power, plus the sealed in power of the running starters. Worst case from a power supply standpoint is the largest inrush starter commanded to start while all the other starters are running.

Formulas to calculate power supply requirements are as follows:

● Deﬁnitions:

SI = Sum of Seal Incurrent LS = Largest Seal Incurrent LI = Largest Inrush Needed TS = Total Seal Incurrent Needed LO = Largest Outrush Needed

TS = (SI - LS) LO = TS + LI

● Max Steady State for the Power Supply ≥ SI

● Outrush for the Power Supply ≥ LO

The voltage on the S811 + and – control terminals must not exceed 30V DC to prevent hardware damage. The S811 will shut down and issue low control voltage fault at control voltages less than 17V DC. The fault will reset at control voltages greater than 18V DC. The Cutler-Hammer control power supplies listed in Table 3-7 are recommended.

Edge Sensing

Edge sensing is set with the Start Control parameter. Edge sensing requires +24V DC power be momentarily applied to pin 1 (with terminal P

at +24V DC) to initiate a start under all conditions. After a stop or fault occurs, the +24V DC must be removed, then reapplied to pin 1 before another start can occur. This control conﬁguration should be used when restarting of the motor after a fault or stop must be supervised manually or as a part of a control scheme.

Level Sensing

Level sensing is set with the Start Control parameter. Level sensing will enable a motor to restart after a fault is cleared without cycling

+24V DC power to terminal 1 as long as:

● Terminal P is supplied with +24V DC (to start from Terminal Block, Input #3 must

also be enabled),

● The Reset Mode parameter is set to AUTO,

● All faults have been reset.

This control conﬁguration should be used where it is desirable to restart a motor after a fault without additional manual or automatic control. An example of this condition would be on a remote pumping station where it is desirable to automatically restart a pump after a power outage without operator intervention.

In the AUTO RESET MODE, CAUTION must be exercised to assure that any restart occurs in a safe manner.

5. Terminal 2 (Jog mode) — If +24V DC power is applied to this terminal while terminal P is at +24V DC, the soft starter will operate in the jog mode as long as +24V DC is on terminal 2 and no faults occur. In jog mode, the soft starter will operate only on the thyristors and the bypass contactors will not close.

6. Terminal 3 (HAND/AUTO setting) — Input 3 selects the terminal block as a source of motor control. It must be energized to enable the terminal block to START or JOG the motor.

7. Terminal 4 (Reset) — Application of +24V DC power will reset the soft starter after all fault conditions are cleared. If the AUTO Reset Mode setting is used with level control CAUTION must be exercised to assure that any restart occurs in a safe manner. See Edge and Level sensing on Page 3-20.

8. Terminals 13 and 14 (Programmable) — At default setting, relay contacts for use up to 230V AC or 24V DC provide bypass contactor status. The contact closes upon bypass and will remain closed until a stop is initiated or a fault occurs. The motor and load may continue to rotate after a stop is initiated if soft stop is being used or if the load inertia is high. See Using an Auxiliary Relay section below for additional contact interface information.

9. Terminals 95, 96 and 98 (Programmable) — At default setting, relay contacts for use up to 230V AC or 24V DC provide fault or ready status indication. See Page 3-15 for a description of their operation.

Connecting a New or Replacement DIM

When 24V DC is ﬁrst applied to terminals + and -, the S811 will send commands to the DIM to reconﬁgure its communication, and the S811 will send a reset to the DIM after conﬁguration is done (this process takes approximately 20 seconds).

Using an Auxiliary Relay

The IT. Soft Starter contains one Form A and one Form C set of auxiliary contacts to indicate its status. A contact between terminals 13 and 14 indicates when the IT. is in bypass (unless it has been programmed to indicate another status). The contacts between terminals 95 and 96 and 95 and 98 indicate the IT. is in a normal or tripped state (unless it has been programmed to indicate another status). Often these contacts are used as shown in Figures 3-15, 3-16 and 3-17 with indicating lamps. In some installations the user may wish to use an electromagnetic relay for indication of the status at a remote location for use by a programmable controller (PLC), or in a 230V AC or 24V DC control circuit.

If the IT. Soft Starter is subject to mechanical shock during operation, it is possible that these contacts may momentarily open, causing nuisance fault tripping of down stream devices. When used with an indicating lamp, a momentary contact opening would not be observed. In order to assure proper application, it is suggested that the following recommendations be followed:

MN03902002E

PLC Interface — It is suggested that a 20 mS delay be programmed to assure the contact status before a change of status is indicated. The application and the environmental issues will determine the exact requirements.

24V DC Control — When a relay is used in conjunction with an electronic control, it is highly recommended that a noise suppression/snubber diode be placed across the relay coil as shown in Figure 3-18. This diode offers two beneﬁts. First, the suppression of any electrical noise generated when the relay coil is de-energized. Second, the diode delays the opening of the relay slightly as it dissipates the energy stored in the relay coil. This delay is often long enough to compensate for the potential effects of a mechanical shock opening the control contact. A typical suppression diode is a 1N4001.

Usually the delay in the relay opening is very small, so if the system is subject to shock, a delay should be added in the external control before the contact change of state is recognized. The resistor is rated 100 ohms at 0.5 watts. The capacitor is 0.25 µF at 250V AC.

In some installations, it may be necessary to use an electromagnetic contactor in series with the soft starter. In this case, it is recommended that the contactor be placed on the load side of the soft starter. The contactor must be closed prior to starting the soft starter and remain closed until the Soft Starter has been stopped to ensure proper soft starter and system operation.

IT. S811 Soft Starter User Manual

If an electromagnetic contactor is used on the line side of the soft starter, additional control circuitry must be supplied by the user when using edge control to ensure the line power is supplied to the soft starter before control power (24V DC) is applied. If this sequence is not followed, the soft starter will fault on either a phase loss or zero voltage-crossing fault. This control scheme is illustrated in Figure 3-20.

If it is desired to place an electromagnetic contactor on the line side of the soft starter, when using level control, no additional control circuitry is required. A start can be completed when the line power is supplied to the unit after the control power (24V DC), providing the Reset Mode parameter is set to AUTO and the unit has a green light status with +24V DC on pin 1.

If the AUTO Reset Mode setting is used, CAUTION must be exercised to assure that any restart occurs in the safe manner.

Chapter 5 — Functional Description

Power

The S811 Soft Starter controls the voltage applied to a three-phase induction motor in order to control the starting torque and provide a smooth starting characteristic. Within the soft starter are three power poles, each of which includes a set of anti-parallel SCRs (thyristors) in parallel with a contact. During a start, the conduction periods of the SCRs are continuously adjusted to apply a gradually increasing voltage to the motor, resulting in gradually increasing torque and a smooth start. As the motor reaches its rated speed, the power pole contacts are closed, bypassing the SCRs for the most efﬁcient operation.

IT. S811 Soft Starter User Manual

Control

Motor

3-Phase

AC Line Voltage

Figure 5-1: Line Connected Soft Starter SCRs

For each start, the length of time the SCRs are conducting current as well as the magnitude of that current determine how hot the SCRs will get. Between successive starts the SCRs must cool down to avoid exceeding their thermal limits. Appendices C and D (Ratings, Cooling and Power Losses) gives the S811’s application ratings for various starting conditions. Staying within these speciﬁed limits should avoid over temperature trips.

When the S811 control circuit senses that the internal temperature has increased above a preset value, internal fans are tuned on to assist in cooling. To maximize fan life the fans are only turned on when needed. Further discussion of fan operation can be found in Appendices C and D.

The software contained in the S811 IT. Soft Starter is the heart of the product. This software allows you to control nearly every aspect of the soft starter’s functionality. In this section, various features and protection options are described.

MN03902002E

Note: In the following descriptions the S811 Parameter Names are shown in italics. You will

ﬁnd a complete listing of these parameters in Appendix A.

Note that the motor current measurements made with a standard meter may not be correct because of the non-sinusoidal nature of the current during starting. The S811 is designed to accurately measure these currents so that the current displayed by the S811’s Digital Interface Module (DIM) is correct.

Starting Options

The following starting choices are available in the S811 IT. Soft Starter:

Voltage Ramp Start

This is the most commonly used mode of soft starting. Starting at an initial value set by the Initial Torque parameter, the voltage applied to the motor is gradually increased at a rate that will reach rated voltage at time tr, set by the Soft Start Time parameter. As the voltage increases the motor develops torque that accelerates the load toward full speed. When the S811 senses that the motor has come up to speed, it quickly completes the voltage ramp and closes the bypass contactor. See Figure 5-2.

It should be noted that a lightly loaded motor takes less torque, and thus lower voltage and time, to accelerate to full speed. For this case the S811 will go into bypass before the ramp reaches full voltage. In other words, the S811 will go into bypass before the Soft Start Time has elapsed.

Kick Start — The Kick Start feature works in both the Voltage Ramp Start and Current Limit

Start modes. By momentarily applying a pulse of current to the motor, it provides an initial boost in torque to overcome the static friction common in some applications. The level of torque boost is set by the Kick Start Torq parameter and the duration of the “kick” is set by the Kick Start Time. Setting the Kick Start Time to 0 disables this feature.

Current Limit Start

This mode is typically used when it is necessary to limit the maximum current during start-up due to line power limitations or other considerations. During a Current Limit Start the S811 applies a constant voltage to the motor, resulting in limited current ﬂowing through the motor’s windings. The level of current is set by the Initial Torque parameter. See Figure 5-3.

Note: Current Limit Starts are not recommended on variable torque load applications like

fans and pumps.

designed for high frictional loads that tend to stop suddenly when voltage to the motor is removed. During Soft Stop the voltage is gradually reduced to zero in the time set by the Soft

Stop Time parameter. See Figure 5-4.

Protection

Thermal Overload

The IT. S811 Soft Starter features an electronic motor overload protection feature. It is designed to protect the motor and power wiring against overheating caused by operating at excessive current levels for extended periods of time.

Entering the motor’s full load current rating, using the Overld Trip FLA parameter programs the overload. The Overld Trip FLA is settable from 32% to 100% of the S811’s rated current.

The overload’s trip class is set using the Ovrld Trip Class parameter. Additional details on the Thermal Overload can be found in Appendix B.

S811 and Motor Protection

In addition to motor overload protection, the S811 has many programmable features designed to protect the motor as well as the soft starter itself.

● Incoming Line Phase Reversal, Loss, Imbalance, Over Voltage, and Under Voltage trips

● Three Overcurrent trips

● Stall and Jam trips

November 2006

For troubleshooting purpose trips are recorded, as they occur, in the S811’s Device Status, Fault List and Fault Queue.

QCPort Network Control

The S811 has two QCPort communications ports, Local (CH1) and Remote Network (CH0).

Local Control (HAND)

S811 Local Control usually consists of the terminal block and one DIM connected to the Local Port (CH1). Additional DIMs, QCPort Cover Controls, as well as other QCPort devices can be connected to the Local Port and used as input devices to control the operation of the S811. Each device sends a Motor Control byte to the S811 which logically combines them and responds appropriately.

Remote Network (AUTO)

The S811 will switch to AUTO control whenever all local control devices have released (de-energized) their LOCAL control signal. When the S811 is in AUTO control it is ready to respond to motor control commands issued through the Remote Network (CH0). Typically an industrial automation ﬁeldbus is connected to the Remote Network port via one of the many network adapters (gateways) available from Eaton.

For further discussion of the network ports, refer to Appendix H.

2. The P and Hand inputs must be energized (24V DC) to enable starting of the Soft Starter from the terminal block.

3. To Start: Apply 24V DC to Input 1 while the P input is energized.

4. To initiate a Stop remove the P input.

5. For 2-wire control, jumper P and Input 1 together.

6. After an Overload Trip, the S811 Soft Starter cannot be restarted until the prescribed cool-down time has elapsed. Cycling power does not reset the timer. If 24V DC power is removed, the soft starter will remember the remaining time and will resume the cooldown timing when power is again reapplied.

7. On frames R, T, U and V when the S811 goes into bypass, a sound similar to contactor chatter can be heard. This sound is the result of multiple contactors closing one after the other in a very short period. It is normal operation intended to reduce the surge current requirements of your power supply.

IT. S811 Soft Starter User Manual

Setup

8. To Jog: apply 24V DC to input 2, (terminal P must also have 24V applied). To stop remove 24V DC from input 2.

9. In jog, the unit will follow the normal start ramp as long as terminal 2 is at 24V DC.

10. Jog operates the same as a normal start, except that the bypass contactors will not close and the soft stop is not functional.

11. Jog is only intended for short term jogging of the motor and not for long term two-wire control.

After all power and control connections have been made and you have read and understood the different operating modes and protection features (Chapter 5) of the soft starter, it is time to program it for your application. The following procedure will take you through the setup of the S811 to match it to your motor and application, “bumping” the motor to verify correct direction of rotation, and tuning of the selected operating mode. After this procedure has been completed, it is suggested that you review the Protection Options of the S811 (Appendix B) and select the appropriate ones for your application. All Protection Options are shipped from the factory “enabled”.

As shipped from the factory, the S811 Soft Starter’s default conﬁguration is sufﬁcient for basic operation but may require some conﬁguration to “tune” it for your application. The following procedure assumes you understand how to “navigate” through the S811’s parameter menu using the Digital Interface Module (DIM) and that the S811 is in its Factory (Out-of-Box) state. Refer to Appendix G of this manual for a detailed explanation of DIM operation.

IT. S811 Soft Starter User Manual

Initial Conﬁguration:

1. It is suggested that the S811 Soft Starter be conﬁgured before applying the line voltage. Before applying the Line voltage, apply 24V DC to the + and - connections of the S811’s terminal block. “Eaton Cutler-Hammer” will be displayed by the DIM while the S811 is powering up. When power-up is complete the DIM should be displaying “3 Ø Line Currents”.

Note: If anything else is displayed, go to Chapter 8, Troubleshooting, for information on

getting the S811 back to a known state.

2. Using the DIM, review the parameter settings in the “Soft Start Confg”, “Overload Conﬁg”, and “Protection Setup” menus. Parameter navigation and menus are located in Appendix A and G. The following setup procedures will use the factory default settings unless changed by you.

3. In the Overload Conﬁg menu, set the Overld Trip FLA parameter to the motor’s nameplate rated current. This setting assumes the motor has a 1.15 Service Factor.

4. Set Ovrld Trip Class parameter for the desired overload trip characteristic (curve).

5. In the Protection Setup menu set the Motor Rated Volt parameter to the motor’s operating voltage.

November 2006

6. If auto fault reset is required, set the Reset Mode parameter in the Soft Start Confg menu to Auto (and Start Control to Level (default)). NOTE: Auto Reset is intended for unattended installations where there is no danger to personnel or other equipment when the motor starts without warning. If Auto Reset is enabled, CAUTION must be exercised to assure that any restart occurs in a safe manner.

7. Apply the Mains voltage and verify that no fault is present. If a fault is indicated, display the Diagnostics menu’s Device Status parameter to determine the source of the fault. Each fault is described on Page 8-6.

a. A Phase Reversal Fault is a likely candidate on new installations. It can be remedied

by either changing the Phase Sequence parameter from ABC to ACB in the Protection Setup menu or removing Mains power and switching the incoming line connections at L1 and L2 of the S811.

8. Quickly Jog (bump) the motor just enough to verify that the direction of rotation is correct. If it is not, remove all power to the S811 and the motor and swap two of the motor’s winding connections.

9. Based on the desired starting mode, Voltage Ramp or Current Limit, complete the conﬁguration of your S811 using the Soft Start Confg menu:

a. Voltage Ramp Start Conﬁguration

i. Initial parameter settings:

Start Method = Voltage Ramp. Initial Torque = 50% Soft Start Time = 60 sec Kick Start Torq = 0% (fans and pumps), 75% (high breakaway loads) Kick Start Time = 0 sec (fans and pumps), 1 sec (high breakaway loads) Soft Stop Time = 60 sec

IT. S811 Soft Starter User Manual

ii. Start the motor and determine the worst case starting conditions. Adjust Initial

Torque for smooth start without hesitation. Rotation should begin within 2 seconds.

iii. If Stall Faults occur at the end of the ramp time, increase Initial Torque, Kick

Start Torq & Time and/or Soft Start Time to get into bypass before the Soft Start Time elapses. Also, verify that the motor is not overloaded.

iv. Adjust the Soft Stop Time for the desired stopping time.

b. Current Limit Start Conﬁguration

v. Initial settings:

Start Method = Current Limit Initial Torque = 50% Soft Start Time = 120 sec Kick Start Torq = 0% Kick Start Time = 0 sec (disabled) Soft Stop Time = 60 sec

vi. Start the motor and determine the worst case starting conditions. Adjust Initial

Torque for smooth start without hesitation. Rotation should begin within 2

seconds and the motor should smoothly accelerate to full speed.

vii. If Stall Faults occur, increase Initial Torque and/or Soft Start Time to get into

bypass before the Soft Start Time elapses. Also, verify that the motor is not overloaded.

viii. After suitable performance has been achieved, determine the starting time to

bypass and set Soft Start Time at 1.25 times this time. For example, if it takes 10 seconds to accelerate the motor and go into bypass, set the Soft Start Time for

12.5 seconds.

ix. Adjust the Soft Stop Time for the desired stopping time.

10. Review the Protection Options of the S811 and conﬁgure the appropriate ones for your application. Refer to Table A-5 on Page A-6 for the list of parameters used in conﬁguring the protections features on your S811 Soft Starter. These parameters are located in the Protections menu of the DIM.

11. The S811 can be operated from a remote automated network. For network conﬁguration details refer to Appendix H of this manual.

IT. S811 Soft Starter User Manual

The S811 Soft Starter can not be started until all faults have been reset. If a fault condition persists, fault reset is not possible and the Status LED remains red. Also, a local start requires that the start source (DIM, terminal block, Cover Control or other similar device) be in HAND mode (L bit in Motor Control Byte = 1). Pressing the START button on the DIM automatically puts that device in HAND.

Deﬁne the Problem

1. The S811 Soft Starter fails to respond in any way to a start command. Look at the front panel of the S811 Soft Starter and determine the state of the LEDs. The following troubleshooting ﬂowcharts will walk the troubleshooter through each step and suggest probable solutions to each problem.

b. With the status LED red, the device will not start. Attempt to reset the S811 Soft

Starter by pressing the S811’s recessed RESET button for one second or pressing the RESET soft key in the Display Mode screen of the DIM. If the LED remains red, use the DIM to determine the fault code and go to the Troubleshooting Fault Table, Table 8-4, to ﬁnd the corrective action for each fault code.

c. The LED is green and the S811 Soft Starter is ready to start. Find the Start source in

Table 8-1 to determine the appropriate corrective action. Verify that the “P” input terminal is at 24V DC. Then try to start the S811 using the DIM.

Table 8-1: Start Command Troubleshooting

Start Source Attempted Suggested Corrective Action

DIM • Verify the “P” (Permissive) input terminal is at 24V DC, either hard

wired or wired through a normally closed STOP button.

• Verify no other motor control device is preventing a start by clearing its permissive bit. Disconnect any other QCPort device that may prevent a start and purge



them from the S811’s device list. This takes these

devices out of the system and simpliﬁes troubleshooting.

Connector Terminal Block • Verify the “P” input terminal is at 24V DC when the start is attempted.

• Verify the “3” input terminal is at 24V DC when start is attempted.

• Verify 24V is applied to the “1” input terminal when the start is attempted.

• If the Start Control parameter is set to Edge, verify the “1” input terminal sees a transition from 0V to 24V after all faults have been reset and the above conditions have been veriﬁed.

• Verify no other motor control device is holding its permissive at 0. If it is, force its permissive = 1 or temporarily remove it from the S811 and

MN03902002E

2. The S811 Soft Starter trips during starting and never reaches bypass. Use the DIM to determine the Device Status fault code and go to the Troubleshooting Fault Table, Table 8-4, to ﬁnd the corrective action for each fault code.

3. The S811 Soft Starter trips during running operation while bypass contactors are engaged. Use the DIM to determine the Device Status fault code and go to the Troubleshooting Fault Table to ﬁnd the corrective action for each fault code.

4. The S811 Soft Starter trips after the stop is commanded. Use the DIM to determine the Device Status fault code and go to the Troubleshooting Fault Table to ﬁnd the corrective action for each fault code.

5. The S811 Soft Starter stops sooner than expected during a soft stop. If the Soft Stop Time is set too long for the motor loading, the motor will begin to stall when delaying SCR ﬁring reduces the voltage. The S811 Soft Starter will detect this stalling and end the stop immediately and not set any faults.

4 Low Control Voltage Fault – The external 24V

power supply voltage is dropping below the minimum required to control the motor.

5 Power Pole Over Temperature Fault – The S811

has detected the internal SCR temperature is excessive. Operating environment above speciﬁed maximum temperature, ventilation holes blocked, fans are not operational, starts per hour exceed speciﬁcations, sensor failure on circuit board, bypass contactor(s) failed to close.

6 Phase Loss Fault – Extreme phase imbalance

condition. Incoming phase disconnected, blown fuse.

7 Phase Imbalance Fault – The imbalance of the

incoming phases exceeds the trip threshold.

9 Under Load Fault – Current supplied to the

motor is below trip threshold. Linkage or belt driven by motor is broken, a clutch or other load engagement device is not operating, the motor is not loaded to the trip current.

10 Over Current Fault – only active in bypass if the

Jam Fault is disabled. Current exceeds the fault threshold.

11 Jam Fault – While in bypass an obstruction has

slowed or stalled the motor resulting in extreme motor current.

13 Bypass Failure Fault – S811 detected that the

internal bypass contact(s) did not close. Possibly opened due to excessive shock or 24V DC control voltage sag (insufﬁcient voltage to maintain contact closure).

November 2006

Try a 24V DC control voltage power cycle to attempt to clear problem. Verify that the S811 is properly grounded. Call Eaton support if the problem persists.

Use recommended 24V power supplies with enough current sourcing capability to close contactors. Verify correct wire size used to connect power supply to S811. (See power supply speciﬁcation for more details.) Verify connections are secure.

Ventilate to speciﬁed maximum temperatures, clear obstructions, verify fans are operational, verify control system is not exceeding the speciﬁed maximum starts per hour.

Repair broken connection, replace fuse.

Correct imbalance problem with mains. Increase the xx Imbalance Fault xx parameters or disable the fault if the other issues cannot be resolved. Make sure your system can tolerate the imbalance.

Repair/replace broken belts, linkage, or clutch, and/or increase load. Reduce Low I Trip % FLA to an acceptable value (0% will disable).

Disconnect power from S811 and any other equipment. Remove obstruction in motor drive train. Verify S811 is properly sized for the application.

Disconnect power from S811 and any other equipment and remove obstruction. Jam Fault can be disabled if trips occur during normal operation. Over Current Fault will provide protection at a higher current threshold.

B-1

IT. S811 Soft Starter User Manual

The thermal overload is designed to protect the motor from overheating caused by excessive current. If the motor is overloaded, the current drawn rises and heats the motor. The FLA sets the trip threshold and the trip class (5 to 30) is set with the Ovrld Trip Class parameter.

If the device trips on a thermal overload, an internal timer is started which inhibits a reset for three minutes. After this timer expires, the device may be reset and the thermal fault is cleared. At this point another internal timer is started, this timer is 26 x 3 or 48 minutes. If another trip occurs before this timer expires, the reset inhibit time is increased to 6 minutes.

Once the trip level reaches 3, it will take 144 minutes to go back to level 2, then 96 minutes to get back to level 1. To get from level 3 to a reset thermal overload at level 1, it takes 240 minutes without a trip. A reset thermal overload at level 1 means the next thermal overload trip will have a 3-minute reset inhibit as in Table B-2.

Table B-2: Thermal Motor Overload Times

Trip Level

1 3 minutes — 2 6 minutes 96 minutes 3 9 minutes 144 minutes



Total 240 minutes to reset to level 1.

Reset Inhibit Time

Cycling power on the device will NOT clear the thermal trip. The thermal memory and the reset inhibit time are saved to the non-volatile memory. These values are reloaded when the device boots and the timer is restarted at the full reset time. This means if the 3-minute inhibit timer has been running two minutes, cycling power will require the user to wait the full three minutes before a reset can clear the overload fault.

November 2006

Reset Time to Previous Trip Level



If the device is shut down when the overload fault is tripped, the temperature is also saved to the non-volatile memory. If the device is left to cool and then powered, the temperature read from the sensor is compared to the saved temperature. If the current temperature is 87% or less of the saved temperature, a full thermal memory reset is initiated.

S811 and Motor Protection Features

The S811 implements the following protection features. Each protection feature is individually conﬁgured and enabled by the user. Some of the features are designed to protect the motor and others are for internal protection of the S811. A summary can be found in Table B-17.

Motor Parameters

One or more of the motor protection features need the following motor parameters. The user must input these values prior to enabling protection.

Table B-3: Motor Parameters Required for Protection

Setting DIM Parameter Range Step Default

Phase Sequence Phase

Instantaneous Over Current

When the bypass contactors are not engaged, the S811 monitors the maximum RMS value of the three phase currents. The unit will trip with an instantaneous over current fault if the maximum value exceeds six times the catalog FLA setting for 1.5 seconds. This internal protection mechanism is most useful for protecting the S811 from starting motor too large for its ratings.

Severe Duty Ratings are deﬁned as any combination of parameters that exceed the Standard Duty Ratings where the ramp time is over 30 seconds, the number of starts per hour exceeds 4, or the current limit set is over 300%. Example: 35-Second Ramp, 5 Starts per Hour, 350% Current Limit @ 40°C Ambient.

IT. S811 Soft Starter User Manual

Cooling

Microcontroller controlled fans are used to cool the IT. Soft Starter. The fans are turned on when the temperature of any of the thermal sensors exceeds preset value. Once the fans are started, they will not go off until the temperature goes below the off set point for 10 minutes.

The fans will also be turned on whenever the IT. is started, stopped or jogged. The fans will remain on for 10 minutes to assure the SCRs are adequately cooled prior to the next start.

If a temperature is sensed above a second preset level, a Pole Over-Temperature Fault will occur. This fault cannot be reset until the temperature returns to a safe level.

Note: The fans will only operate if 24V DC is applied to the + and – terminals. Cycling power

during the 10 minute timeout after a start, stop or jog will reset the fans to off.

Power Losses

The following table lists the maximum power loss for each IT. Soft Starter when it is operating in the across-the-line mode with its bypass contactor pulled in. These losses should be used in conjunction with the losses of another cabinet mounted device to determine the enclosure size and any cooling requirements.

Cooling

The fans will also be turned on whenever the IT. is started, stopped or jogged. The fans will remain on for 10 minutes to assure the SCRs are adequately cooled prior to the next start.

If a temperature is sensed above a second preset level, a Pole Over-Temperature Fault will occur. This fault cannot be reset until the temperature returns to a safe level.

Note: The fans will only operate if 24V DC is applied to the + and – terminals. Cycling power

during the 10 minute timeout after a start, stop or jog will reset the fans to off.

Appendix E — Motor/Application Considerations

Using MOVs

Most utility power systems experience periodic transient voltages. Line or power factor correction capacitor switching, nearby lightning strikes, utility supply faults, or a user starting or shutting down a large load such as a motor can cause these voltages. The IT. Soft Starter has been designed to handle transient voltages of up to 4 kV lasting up to 20 µS.

If transient voltages of greater magnitude or longer duration than the standard withstand capability are expected, a protective module must be installed. The protective module contains metal oxide varistors (MOVs). MOVs are devices that remain in a passive state until a transient voltage occurs. Under the transient condition, the MOV turns on and holds the peak line voltage down to a level less than the IT. transient voltage rating. When the transient clears, the MOV returns to a passive state.

Eaton offers two MOV option kits:

Table E-1: MOV Kit Options

Catalog Number Description

IT. S811 Soft Starter User Manual

EMS38 600V (max) MOV for S811N and S811R Soft Start

EMS39 600V (max) MOV for S811T and S811V Soft Start EMS41 690V (max) MOV for S811T, V35 and S811V, V35

The EMS38 is panel mounted, while the EMS39 and EMS41 are mounted directly on the IT. Soft Starter.

In situations where an MOV must be used, the installer may choose to apply a different transient absorption device, but it must be equivalent to the EMS38, EMS39 or EMS41. These MOVs may also be used on the load side of the soft starter where long cables connect the motor to the soft starter or where the cables are located outdoors.

Squirrel Cage Motor

This is the most common application. The motor is conﬁgured with three motor leads available. In this case, wire the motor to the soft starter with one lead per phase, observing proper

phase rotation. An in-sight disconnect means should be installed, per code requirements.

Wye-Delta Motor

The wye-delta motor is a traditional way of achieving a reduced voltage start using regular contactors and starters. In this method, the motor is constructed with all six leads brought out to connect the unit in a wye conﬁguration. This allows about 58% of the current (33% starting torque) to be applied during start-up. A timer is used to control the circuit and switch to the delta conﬁguration as the unit approaches full speed.

In this case, wire the six-lead motor in a standard delta conﬁguration. The soft starter is then used to control the voltage and motor torque without the need for additional circuitry. An insight disconnect means should be installed, per local code. The IT. Soft Starter must be wired into the three-phase line feeding the three main motor input leads as would be done for normal across-the-line starting. It must not be wired internally between motor windings in

an inside-the-delta conﬁguration. If an inside-the-delta starting conﬁguration is desired, please contact Eaton for details about our inside-the-delta soft starters, designated S811xxxxxD.

Part Winding Motor

The part winding motor is another design created to help achieve a soft start to the load. A part winding motor is constructed of two separate (but parallel) windings. When using a traditional starter, the ﬁrst winding would receive full voltage. This winding supplies as much as 400% of the motors FLA; about 45% starting torque in a delta conﬁguration for motor startup. After a timed delay, full voltage is applied to the second winding. The second winding acts in parallel with the ﬁrst to provide for normal running current. Part winding motors are available in both a wye and delta conﬁguration, dependent upon the manufacturer. Refer to the motor nameplate for the correct wiring information. In this case, wire the two windings in parallel. The soft starter is then used to control the current applied to the motor. An in-sight disconnect means should be installed, per code requirements.

Dual Voltage Motor

A dual voltage motor should be wired into the appropriate conﬁguration for the line voltage it is being applied to. Refer to the motor nameplate for the correct wiring information. The soft starter must be selected for the appropriate line voltage.

Multi-Speed Motor

Some motors have multiple windings to allow operation at different base speeds. The multiple speeds are sometimes utilized for soft starting and other times for a process requirement of the machine to which it is attached. If only one speed is required, the motor should be wired for that speed. If multiple speeds are required, the appropriate contactors will need to be connected to the output of the Soft Starter. The contactors must be in the selected speed position before the soft starter is started. The motor must be stopped and the soft starter turned off before the speed selection contactors are changed.

Precaución

Other Winding Conﬁgurations

Motors with other winding conﬁgurations, designed for speciﬁc characteristics, should be wired in a fashion consistent with their intended use. The motor nameplate contains information on the available conﬁgurations. The motor winding conﬁguration chosen must be appropriate for the available line voltage. The soft starter must also be selected on the basis of the conﬁguration chosen.

Power Factor Correction Capacitors

Power factor correction capacitors should be installed on the line side of the soft starter. It is recommended that at least 10 feet of cable be between the capacitor and the soft starter. The power factor correction capacitors can be switched with a separate contactor. NEMA ICS21988 Part 2-210.81.01 provides recommendations for when a separate contactor should be used to switch the power factor correction capacitor including high inertia loads, reversing motors, frequently jogged motors and multi-speed motors.

It is not recommended that the power factor correction capacitors be used on the load side of the soft starter. If used on the load side, the overload relay will measure the combination of capacitor and motor current causing the overload relay to not function correctly.
