Output Errors
Troubleshooting Problems in Modules
Input turns ON/OFF irregularly.
Errors occur in 8-point or 16-point blocks, i.e., for the
same common.
Input indicator does not light, but input operates nor-
mally.
None of the outputs will go ON.
None of the outputs will go OFF.
A specific bit address’ output does not turn ON.
(Indicator is not lit.)

Probable cause
Probable cause
Adjust external input voltage to
within the proper range.
Take protective measures
against noise, such as:
(1) Install surge suppressor.
(2) Install isolating transformer.
(3) Install shielded cables
between the inputs and loads.
