
Occurrence of the same system alarm at different channels
When the advanced system alarm is used, if the system alarms with the same error code occur in different channels

Therefore, if the system alarms with the same error code occur one by one, the time of later system alarm occurrence
is not reflected to the GOT.

Confirmation of the channel No. at which a system alarm occurred
When a system alarm occurred, confirm the channel No. where the alarm occurred, using the procedure indicated
below.
(1) Check by [System alarm display] of the utility.
