LED DIA Operational status
red
Teach process failed or
configuration changed
without new teach-in e.g
•24-V-signal on input of
RESET button although
"automatic reset" was
taught
•external device monitoring
activated although no exte-
rnal device monitoring was
taught (e.g. because the
contactors were open dur-
ing the teach-in)
•the DIP switch setting was
changed without a new

EDM error
Possible causes:
Malfunction on the contactor
monitored,
Actuator not outside the res-
ponse range long enough af-
ter removal from the respon-
se range, as a result the
feedback circuit cannot close
in this short time. Please
note the dropout time for the
contactor monitored.
