Table 9.B Fault Descriptions (cont.)
Fault Name and Number Fault Description Action to Take
Jam/Stall
F5
The Jam DIP switch on the SMP-3 overload relay is ON, and
greater than 400% of the FLC current for
≥
0.5 second has been
detected after the SMP-3 overload relay has operated at
≥
30%
FLC for more than one trip class time period.
1. Ensure that the motor is free to rotate.
2. Check the load and drive system for high friction or jam.
Illegal FLC Setting
F6
The DIP switches on the SMP-3 overload relay are set below the
minimum allowable FLC setting for that device. Ensure that FLC DIP switches on the SMP-3 overload relay are
set higher than the minimum FLA. (See Table 3.I on page 3-36.)
Non Vol Memory
F7
A protection fault has occurred, but the non-volatile memory
used to store a protection fault has malfunctioned. 1. Perform the action specified for an overload, phase loss,
Ground Fault, and Jam/Stall fault.
2. Reset the SMP-3 overload relay.
3. If fault continues to occur, check with the factory.
Communication Fault
F8
The SMP-3 overload relay has lost communication with an
adapter, such as a HIM or a communication module. 1. Check that DIN connectors are still plugged in to the SMP-3
overload relay and the slave device.
2. Check that the total communication cable lengths do not
exceed 10 meters.
3. Check cable for damage.
4. Try another cable.
5. Try another adapter.
