Table 12.3 Troubleshooting: Operator Panel Malfunctioning
Symptom
Probable Cause
Solution
All LEDs and displays are off
or unintelligible.
Incoming ac deficient.
MP-3000 malfunctioning
The MP-3000 operates down
to 55% of rated voltage, but
such a low voltage isn't
normal and should be
diagnosed.
Verify that 120 or 240 Vac
(±15%) exists between
terminals 4 and 7.
Remove ac power completely
for 10 seconds and reapply. If
problem persists, return the
MP-3000 to the factory for
repair.
OPTO ERR message
Optocoupler failure trip based
on bad timing of ac input
waveform zero crossings.
Check the frequency setting
P1L7 for 50 or 60 Hz as
appropriate. Make sure 120
Vac is used for discrete inputs.
Energizing with dc will cause
this error message.
Metered current readings too
low or too high.
Incorrect current transformers
and/or PCT ratio setting P1L5.
Acceptable Ct ratio is dictated
by motor nameplate FLA.
PCT should be set to the
actual Ct ratio. See Ct
application advice in Section
5, paragraph 5.1.5.

NOTES:
1. Refer to Table 12.3 for OPTO ERR.
2. Setpoint P12L16 lets the user choose whether these internal failures produce alarm plus trip,
or just an alarm.
