1.3 Alarms
Reflash Alarm
When multiple alarms are assigned to one alarm output relay, this function notifies the
occurrence of subsequent alarms after the relay is activated by the first alarm. When
subsequent alarms occur, the output relay is released temporarily (approximately
500 ms).
The reflash alarm function is set to three output relays (I01, I02, and I03 (I01 and I02 for
the /A1 option)).
By default, the reflash alarm is disabled.

to I03 are set to OR operation and non-hold operation regardless of the settings specified in
“AND/OR Operation of Alarm Output Relays” and “Non-Hold/Hold Operation of Alarm Output
Relays” described below.
• If diagnosis output is enabled, I01 is set to diagnosis output.
