S801+ Soft Starter
MN03900002E—November 2012

33
Motor Under Load
(Disconnect)
Current drawn by the motor is below trip
threshold.
Repair/replace failed couplings.
Failed motor coupling.
Increase load.
Load engagement device is not operating.
Motor is not loaded
Notes:
When the internal bypass contactors are closed, the average value of the 3 phase currents is monitored as a % of FLA.
34
SCR Instantaneous Over
Current
Excessive SCR Current during the start
ramp.
Increase
Soft Start Time
and/or
Initial Torque
potentiometers.
Only active when
Stall
Fault is disabled.
Reduce starting load.
Verify S801+ is properly rated for current.
Notes:
The maximum RMS value of the three phase currents is monitored. The SCR Over Current Trip threshold is 3X FLA.
41
Low Control Voltage
Voltage at Terminal “+” falls below 17 Vdc. Verify power capacity (amperage) of 24V power supply to close
contactors.
The external 24V power supply voltage is
below specifications and/or insufficient
current capacity.
Power supply voltage is intermittent and/or drifting. Read value on
Monitoring Menu.
Verify correct wire size (14 gage minimum) used to connect power
supply to S801+. Inspect for wire damage or corrosion.
Check voltage drop between power supply and Terminal “+”.
Possible internal hardware failure.
Notes:
Only voltage at Terminal “+” is monitored for condition that may generate this fault. Inspect control voltage circuit for proper configuration. If the
24 Vdc control voltage is lost at Terminal “P” just prior to the voltage loss at Terminal “+”, the soft starter will recognize this condition as a STOP
command. This condition would cause a shutdown of the soft starter without logging FC41. Suspect source voltage should be monitored for the
appropriate length of time to determine if the voltage drifts more than 0.1 Vdc from nominal, or if the voltage is intermittent.
When selecting a power supply, ensure that the outrush capacity of the power supply meet or exceed 240 watts at 24 Vdc for 100ms, minimum.
42
Firmware Incompatibility or
Hardware failure.
Hardware failure.
Failed unit. Contact EatonCare for service information.
43
Internal Communications
Communications to DSP have been
interrupted.
Firmware is not communicating internally.
Possible hardware failure.
Cycle 24 Vdc control voltage power to attempt to clear problem.
44
Internal CPU
Firmware Incompatibility or
Hardware failure on the printed circuit board (PCB) and/or the
firmware is corrupted.
Hardware failure.
Contact EatonCare for support.
45
Internal Program Memory
Corrupted firmware or memory.
Cycle 24 Vdc control power to the S801+.
Contact EatonCare for service.
*
CIM LEDs Non-functional
Control Interface Module failure
Replace the CIM to restore operation.
Notes:
There is only one model CIM, part number EMA71 for all S801+ soft starters. All operating parameters for the soft starter are stored in
non-volatile memory on the printed circuit board, so the CIMs may be exchanged between all models (sizes) of soft starters if a replacement CIM
is not available.
The S801+ may be operated without the CIM installed by simply removing the control prior to energizing the unit (24 Vdc).
