Failure Type Action to Take General Problem
Communication The communication link between the
SMP-3 and an adapter does not appear to
be functioning. 1. Check the HIM display (if applicable). If the display appears to be cycling between menus:
a. Check the communication connection per the procedure described in Table 9.B for a
Comm Fault.
b. Induce a Test fault on the SMP-3 overload relay. If the SMP-3 overload relay does not
trip, consult the factory.
If the display is de-energized:
a. Check the communication connection per the procedure described in Table 9.B for a
Comm Fault.
b. Follow the Power-up Failure troubleshooting procedure previously described.
2. Check the SCANport status LED (if applicable) on the Communication Module. If the LED is
“On”:
a. Check the non-SCANport communication connections (i.e., RIO, DeviceNet).
If the LED is “Off”:
a. Check the communication connection per the procedure described in Table 9.B for a
Comm Fault.
b. Induce a Test fault on the SMP-3 overload relay. If the SMP-3 overload relay does not
trip, consult the factory.
3. Check the Logic Mask Parameter. Refer to Chapter 8 for programming instructions.
Communication Comm Fault exists. Refer to Table 9.B for instructions regarding how to correct Comm faults.
