Troubleshooting
General
In this section of the manual, we present a procedure you
can follow to diagnose a problem with your S801+.
While many potential situations are outlined in this section, it
is possible you may run into a problem that is not covered
here. If you have worked through the following
troubleshooting procedure and find that you require further
assistance, please contact Eaton.
Please have the following information ready when you call:
Before You Begin to Troubleshoot
WARNING
Make sure you read and understand the procedures in
this manual before you attempt to set up or operate the
equipment.
WARNING
HIGH VOLTAGE. Do not work on energized equipment
unless absolutely required. If the troubleshooting
procedure requires equipment to be energized, all work
must be performed by properly qualified personnel,
following appropriate safety practices and precautionary
measure.
We highly recommend that you read this entire section of
the manual before you begin to troubleshoot the S801+ Soft
Starter.
You may want to obtain the following equipment to aid you in
troubleshooting:
●
Multimeter
●
Clamp-on ammeter
Always assume the S801+ has high voltage applied and take
proper precautions while troubleshooting the soft starter and
associated equipment. Read all precautions at the front of
this manual before starting the troubleshooting process.
Fault Codes
To obtain the fault flash codes from the CIM, hold the RESET
button (located below the CIM) down or apply 24 Vdc to
terminal 4 and count the number of times all the LEDs on the
CIM flash.
For example, if you see three flashes, and then two more
flashes after a short pause, the flash code is 32.
The CIM can provide multiple flash codes, if more than one
error condition caused a stop. Once you see the same flash
code repeated, you have seen all the flash codes for the error
conditions that caused the stop.
For example, if you see three flashes, a pause, then two
flashes, a slightly longer pause, then four flashes, a pause,
then one flash, the flash codes are 32 and 41.
If you then see three flashes, a pause, then two flashes, you
are seeing the first code again. This means you have seen all
the flash codes for this stop.
You may now release the RESET button or remove 24 Vdc
from Control terminal Block Terminal 4.
Note: If an overload trip has occurred, 24 Vdc power must
be applied to allow the overload thermal memory to
reset. Depending on the overload history prior to the
latest trip, this may be as long as 9 minutes.
A list of flash codes and the faults they represent is shown
below.
