Lug Bolt Torque Support

Power Wiring

WARNING
Hazardous voltage can cause electric shock and burns.
To avoid shock hazard, disconnect all power to the
controller, motor or other control devices before any
work is performed on this equipment. Failure to do so
will result in personal injury, death or substantial
property damage.
Do not apply a disconnect device on the output of the
S611 soft starter unless a means to turn off the soft
starter when disconnect switch is open is used. Opening
disconnect while the soft starter is operating may cause
a malfunction. Closing disconnect switch while the soft
starter is operating will result in a soft starter failure and
potential equipment damage and personnel hazard.
Note: Short circuit protection must be applied on the line
side of the soft starter.
Do not attempt to lift the soft starter by the cover
only.

Lug Installation
Install the lugs below the bus bar to assure anti-rotation.
Refer to figure “Lug and Bolt Torque Support” on this page.

Note: When securing the lugs onto the bus bars of the soft
starters, use a suitable tool such as another wrench to
counteract the bolt torque and prevent excessive side
loads being placed on the supports. Refer to figure “Lug
and Bolt Torque Support” above.
Remove the tie wraps for CTs on Frames C, D, E, and
F. Move each CT to the load cables during assembly
as shown in the figure “CT Location” on Page 2. Each
CT should be properly supported with tie wraps
ensuring that the CT is not supported by the leads.
Properly secure CT leads.
When securing the Current Transformers (CTs) onto
the T1, T2, and T3 bus bars of the soft starter, correct
orientation of the CT must be observed to ensure
proper operation of the soft starter. Each CT is marked
with a symbol “IX” adjacent to the leads. This symbol
shown in the figure “CT Polarity Identification” on
Page 2 indicates the line side (or voltage source side)
of the device.

3.

The S611 Operation and Protection parameters may be
edited when 120 Vac control power is applied to 120 Vac
supply (TB1). Mains power is not required to edit and
save Operation and/or Protection parameters.

f.
4.

If Stall Faults occur at the end of the ramp time, increase
Initial Torque, Kick Start Torque and Time and/or Soft
Start Time to achieve bypass before the Soft Start time
elapses. Verify that the motor is not overloaded.

To setup the S611 Operating parameters (Operation
mode), perform the following steps:
Enter motor FLA.

b.

Enter motor rated voltage.

c.

Select start method if required (default = voltage
ramp, or pump start).

d.

Enter Start time from table on Page 7 (default =
20 seconds).

e.

Enter initial torque from table on Page 7 (default =
45%).

Application Notes
Adjust Initial Torque for smooth start, motor rotation
should begin within 2 seconds.

If any 120 Vac power source other than the normal system
control power source is used to power the control circuit to
edit parameters, connections must be made in compliance
with all local, state, and national electrical codes.

a.

Enter Stop time, Kick Start time, and Kick Start
torque if desired (default = 0).

After suitable performance has been achieved with either
method, 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.
5.

In the Protection Mode, set the Protection parameters
to the desired values. Refer to table on Page 7.

6.

For optional advanced configuration parameters refer to
the user manual.

Single-phase missing and/or open fuse
or breaker

Motor not at rated RPM at end of start
ramp time and/or current is in excess of
trip threshold
Bypass contactors not closed at the end
of the start time (start current low/ramp
time short)

SCR Overcurrent

Under Load

•
•
•

Excessive SCR current during the start
ramp
Only active when Stall Fault is disabled
Loss of motor load
Trip threshold set too high
Excessive current fluctuation during
operation

Connect to correct supply voltage
Verify that mains voltage is within acceptable values
Verify Motor Rated Voltage in the Operation mode is
set to the correct value
Connect to correct supply voltage
Verify Motor Rated Voltage in the Operation mode is
set to correct value
Set Phase Sequence to match incoming sequence OR
Exchange two incoming mains phases
Verify that all circuit breakers are closed or fuses are
serviceable
Lengthen Soft Start Time and/or increase Initial
Torque in the Operations mode
Increase trip threshold
Loads that are heavily loaded (high inertia) during a
start such as fans will often need an initial torque
setting much greater than the factory default
Set Kick Start parameters
Increase Soft Start Time and/or Initial Torque
parameters in Operation mode
Reduce starting load
Verify S611 is properly rated for current
Inspect for failed motor coupling or pump cavitation
Reduce trip threshold
Increase trip delay time to ride through transient load
changes

Note
 Shorted SCRs are the most common mode of SCR failure. With power completely removed from the unit, measure the resistance of each pole, line to load.
If the resistance is near zero (less than 5 ohms), it is most likely that the SCR is shorted. Resistance of a serviceable SCR is approximately 10k ohms.
Resistance typically moves to a lower value as the SCR ages. This feature may be disabled (not recommended).

Troubleshooting

S611 Fault Codes, continued
Code

Fault

Condition

Solution

29

Current Unbalance

•

The current imbalance of the incoming
phases exceeds the trip threshold

•
•
•

Correct imbalance problem with mains
Increase the Current Imbalance parameters
Disable the fault if the other issues cannot be
resolved

30

Current Phase Loss

•
•
•

Incoming phase disconnected
Open fuse or breaker
Phase imbalance exceeds specifications
or trip parameter
Severe voltage phase imbalance

•
•
•

Repair broken connection
Replace fuse
Inspect system for phase imbalance conditions

31

Voltage Phase Imbalance

•

The voltage imbalance of the incoming
phases exceeds the trip threshold

•
•
•

Correct imbalance problem with mains
Increase the Voltage Fault Imbalance parameters
Disable the fault if the other issues cannot be resolved

33

Jam

•

Soft starter in bypass: Motor below rated
RPM and/or current exceeds 3 x motor
FLA

•
•
•

Remove obstruction
Verify proper FLA setting in Operation mode
Jam fault can be disabled if trips occur during normal
operation (Overcurrent fault will provide protection at
a higher current threshold of 4 x catalog FLA)

34

Contactor Overcurrent

•

Only active in bypass if the jam fault is
disabled
Current exceeds the fault threshold of
4 x catalog FLA

•
•

Remove obstruction in motor drive train
Verify S611 is properly sized for the application

Temperature sensor failure
Internal connection failure

•
•

•

Internal hardware failure (sensor and/or cable)
Note: Disabling this feature (Temp Sense fault in
Protection menu) will remove protection from
excessive temperature exposure (not recommended)
Not field repairable, contact Eaton Support

•

•
35

Missing Temp Sensor

•
•

*

Cannot RESET fault

•
•

Fault condition still exists
Soft starter has not received RESET
signal

•
•

Troubleshoot fault and correct defective condition
Attempt alternate methods of RESET

NC

No communication

•

Firmware not programmed, firmware
corrupted

•

Contact EatonCare for service

Note: All mains and control power connections must be completed and voltage applied prior
to a START command. Failure to make all connections will result in one or more faults.
All isolation and/or reversing contactors must be staged prior to any START commands.
Manipulating contactors after the START command will result in one or more faults.
