Contact signals can be generated from alarm output relays when alarms occur. The
number of output relays is 2 (/A1), 4 (/A2), or 6 (/A3). The alarm output relays are
denoted as I01 to I06 on the recorder.
The following functions can be assigned to the alarm output relay.
Diagnosis Output
The diagnosis output can be assigned to alarm output relay I01.
The relay is activated when there is an error in the plotter operation on the pen model,
when a burnout is detected, or when there is an error in the A/D converter. Output relay
I01 is normally energized and de-energizes when an error is detected (de-energized
operation and non-hold operation).
