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.
