Define the Problem
1.
If the S801+ Soft Starter fails to respond in any way to a start command., look at the
Control Interface Module of the S801+ Soft Starter and determine the fault status of the
unit. The following troubleshooting flowcharts provide a logical sequence to determine
issues and suggest probable solutions to each problem.
Start Command Troubleshooting Flow Chart
Troubleshooting—S801+ Does not START
a. With the Status LED illuminated RED, the device
will not start. Attempt to reset the S801+ Soft
Starter by pressing the S801+’s RESET button for
one second. If the Status LED remains RED, use
the Control Interface Module (CIM) to determine
the fault and fault code and go to the
Troubleshooting Fault Table in
Appendix E
to find
the corrective action for the fault.
b. If the Status LED is GREEN, the S801+ Soft Starter
is ready to start. Determine the Start source in
table above to aid in determining the appropriate
corrective action. Verify that the
Permissive
input
terminal is at 24 Vdc. Then start the S801+ the
Control Input terminal block. If the S801+ does
not start, verify that the
Start
input terminal is at
24 Vdc.
