Incoming ac decient
MP-3000 malfunctioning
The MP-3000 operates down to 55% of
rated voltage, but such a low voltage is
not 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 it. If the problem
persists, return the MP-3000 to the
factory for repair.
OPTO ERR message An optocoupler failure trip based on bad
timing of ac input waveform zero cross-
ings
Check the frequency setting P1L7 for
50 or 60 Hz, as appropriate. Make sure
120 Vac is used for discrete inputs.
Energizing with dc causes this error
message.
