12. ALARM OUTPUT
12.1 Alarm Output Programming Items
This explanation is only for the alarm output (option). The alarm output programming is necessary after
programming the “alarm”.

Programming Items for Alarm Output
1) Relay No.
Setting of the relay No. where the alarm information (activation/reset) of each alarm point is
to be output. Set them to each alarm point.
2) Output wiring
Setting to AND or OR for each relay No.. When one relay is used by multiple alarm points,
you can select AND or OR for the output wiring.
(1) Relay coil phase: Setting whether N and O terminals are shorted (Energized) or opened
(Non-energized) when an alarm activates.
(2) Relay output latch: Setting whether the alarm status is to be continued until is
pressed (Hold) even if the alarm becomes reset condition, or it is reset (Not hold) at the
same time as resetting of the alarm.
3) Output mode
(3) Alarm display
*
latch: Setting whether the alarm display is kept displayed until is
pressed (Hold) even if the alarm becomes reset condition or turned off (Not hold) at the
same time as resetting of the alarm.
* Alarm display: ALARM status lamp

*This is the “Alarm” programming. The relay No. is
fixed at 0 in the standard specifications (AH is fixed
at 00). 1 to n (Note) should be set only when alarm
output (option) is added. (0 means no output.)
(Note) n: 6 or 12 depending on the number of output
points.
RD200: 6 only

of output points (Rel;ay No. is 1 to 12 for
12-point outputs.).
