S801+ Fault Codes
Code Fault Condition Solution
S. S. Trip LED General Fault Occurs when any dedicated LED and/or
Fault Code is logged into the S801+ memory Check for presence of dedicated LEDs
Check for presence of fault codes.
Note: Fault codes are not time stamped. Verify that the code is a
recent occurrence rather than an “old” code.
Notes:
The most common occurrences of faults may be; Overtemperature (High operating temperature); Tr setting (Ramp time too long); Hardware
failure, Load disconnect (Insufficient motor load). These faults may be corrected by the appropriate actions.
If the RVSS has stopped and the S.S. Trip LED is not illuminated, verify that a STOP command was not errantly received by the unit. Failure to
note the validity of a STOP command and failing to note an old fault code may result in needless troubleshooting activities.
JAM LED
(FC13)
Jam Soft Starter in Bypass: Motor below rated
RPM and/or current exceeds 3X FLA. Remove obstruction.
Verify proper FLA setting on FLA potentiometer.
Jam Fault can be disabled if trips occur during normal operation
Notes:
The Jam Fault may be disabled (not recommended). The maximum RMS value of the 3 phase currents is monitored when the internal bypass
contactors are closed.
The Jam Fault Trip threshold is 3X Motor FLA and is not user settable. Jam Trip Delay is 1.5 seconds and is not user settable.
STALL LED
(FC12)
Unit railed to reach
synchronous speed Motor failed to reach synchronous speed
(90% motor rpm or greater) prior to the
expiration of the START time. Clear application of the cause of the Stall condition.
Verify ramp time is sufficient for the application.
Verify the Initial Torque setting is appropriate for the application
Notes:
Motor rotation should begin within 2 seconds of energization. If motor rotation does not begin within 2 seconds, increase Initial Torque or utilize
the Kick Start feature to initialize motor rotation.
PH. Loss LED
(FC22)
One or more phase voltages
not present. One or more phase voltages not present. Verify that all connections are correct and tight and voltage is of the
proper value.
Phase voltages and/or currents have
significant imbalance. Verify continuity of fuses or breakers, disconnects or isolation
contactors
Verify all connections are correct and tight.
Verify that imbalance is within limits during Run operation in bypass.
Notes:
Verify fuse integrity by using the proper test methods. Performing a resistance test with an ohmmeter across a fuse may not necessarily produce
accurate measurements. This fault may also be triggered by an excessive degree of phase imbalance. Imbalance may be generated by degraded
connections due to loose hardware, loose connections, cracked or damaged connections/hardware, degraded contacts in isolation contactors,
and loose connections in junction boxes.
Ph. REV LED
(FC14)
Phase rotation is not ABC Improper phase connections. Exchange any two phase in the line connections of the soft starter.
Phase loss. Correct phase loss and/or current imbalance conditions.
Notes:
In new applications, phase connections may not be proper when setting the correct direction of rotation of the motor. In existing applications,
momentary phase loss and/or current imbalance may trigger phase reversal as with only 2 phases present, the unit cannot determine the
direction of phase rotation.
OVLD Trip
LED
(FC11)
Motor Overload Motor is operating in excess of rated FLA. Verify motor load is within specs.
FLA setting not correct. FLA potentiometer not set correctly. Verify that the FLA potentiometer is set correctly for the application.
Improper Trip class. Trip class potentiometer not set correctly. Verify that the trip class potentiometer is set correctly for the
application.
Failed current sensor RVSS Hardware failure. Possibly current sensor failure—contact EatonCare for service.
Notes:
Verify that the service factor has been accommodated in the FLA potentiometer setting. This trip condition may not be immediately reset,
depending on the overload condition. If the unit cannot be reset until a period of time has elapsed strongly suggests that an actual overload
condition occurred, rather than a device or component failure. In a true overload condition, a period of time may be required before the unit is
able to be RESET. Initiating another START after a reset may result in another overload trip due to retained thermal memory.
