a Starter must be ordered with pumping software installed.
b A value of one (current limit start) may be selected for this application, but longer starting times and constant loads should be observed when starting.
c Two second stop time must be set if this is an ammonia compressor application.
d Customers operating equipment on either ungrounded systems or high resistance grounded systems may need to adjust the severity and/or duration of imbalance protection.
These power systems periodically experience phase angle shifts that can be picked up as a false imbalance trip.

FLA setting calculation
The FLA setting is a function of the product of the motor nameplate
full load amperes (FLA) and a multiplier from the service factor
multiplier (SF) in Table 2 below.
FLA setting = Motor FLA x SF multiplier
For example, an S811R13N3S with a 100A, 1.15 service factor motor
should have an FLA setting of 115 (100 x 1.15).
Please refer to sizing charts in product user manual, MN03902002E,
or call 877-ETN-CARE (386-2273) for assistance in sizing a soft
starter for specific applications.

Wiring and control check list for operating
through the control terminal block
A jumper is installed between terminals P and 1 for two-wire
control (e.g., RUN/STOP toggle switch or PLC control)
24V power supply meets minimum requirements (55 watt
steady-state, 240 watt inrush for 180 ms, 30 Vdc maximum.)
Control power wire for the positive and negative terminals
is 14 AWG or larger
Control wire length less than 100 feet
24V is supplied to pin 3 on the control terminal block if controlling
through these terminals is desired
Power wiring check list
24 Vdc control voltage will be applied to terminal P
Phase sequence is correct (ABC); otherwise, soft starter will
trip on phase reversal
If output isolation contactor is used, it cannot open until the
soft starter stops to prevent a low current trip
After completing the above, apply line power, apply 24 Vdc control
voltage, and then initiate start signal to energize motor.
Check list—settings—special applications
You may improve performance if operating on generator power
by setting the kick start time to 2 seconds and kick start torque
to half the value of the initial torque setting. This creates a step
loading effect of the generator, allowing the governor to regulate
the power demand of starting larger motors.
Troubleshooting
For additional setting details, refer to the S811 User Manual
MN03902002E available at www.eaton.com/electrical.
