Energize or De-energize Operation of the Alarm Output Relay
You can select whether to energize or de-energize the alarm output relay when the
alarm occurs. By selecting de-energize, the alarm output relay will operate in the
same manner as when the alarm occurs when the power supply is disrupted.
Energize or de-energize applies to all alarm output relays. The initial value is set to
Energize.

Hold/Non-Hold Operation of the Alarm Output Relay
There are two methods in operating the alarm output relay.
• Turns OFF the output relay when the cause of the alarm is no longer met (non-
hold).
• Holds the output relay ON until the alarm acknowledge operation is executed
(hold).

Note
If the reflash alarm is turned ON, I01 to I03 are set to non-hold. Specifying hold produces no
effect.
Alarm Output Release (Alarm ACK) Operation
When you perform the alarm ACK procedure, all alarm displays and relay outputs (/
A1, /A2, /A3 option) are released. However, this procedure is not valid if the alarm
display/output relay operation is set to non-hold. This cancellation procedure can be
performed using FUNC key or USER key, or via remote control (/R1, /PM1 option).
Note
When the basic setting mode is entered, the activated/released condition of the previous
alarm output relay is held. Alarm detection is not carried out in the basic setting mode, and
you cannot release the alarm output relay.
