AND/OR Operation of Alarm Output Relays
When multiple alarms are assigned to one alarm output relay, the condition for activating
the alarm output relay can be selected from the following:
• AND: Activated when all assigned alarms are occurring simultaneously.
• OR: Activated when any of the specified alarms is occurring.
Alarm
Channel 01
AND
Channel 02
OR
Alarm output relay
The alarm output relays assigned to AND operation are specified as follows: “I01 (first
relay) to Ixx (where xx is the relay number).”
The default setting is “no AND relay.”
Note
• If the reflash alarm is enabled, I01 to I03 are fixed to OR operation. Specifying AND
produces no effect.
• If diagnosis output is enabled, I01 is set to diagnosis output. Specifying AND produces no
effect.

Energized/De-energized Operation of Alarm Output Relays
You can select whether the alarm output relay is energized or de-energized when an
alarm occurs. If de-energized is selected, the status of the alarm output relay when an
alarm occurs is the same as the status that results when the power is shut down. The
setting applies to all alarm output relays.
The default setting is energized.
