12. ALARM OUTPUT 12.2 Programming of Relay No.
This explanation is only for the alarm output (option). Program the relay No. for each alarm point by referring the
“Programming relay No.” screen in “Section 11.5 Alarm,
4 Programming flow chart, 2) With alarm output
(option)”.

Alarm Output Terminals and the Status
When an alarm is in active at an alarm point, the relay
No. (alarm output terminal No.) specified for the point
is activated.*
*The terminal activation differs depending on the
programming of the relay coil to “Energize” or “Non
energize”.
⇒ See Section 12.4.

Programming Relay No.
For programming [Relay No.], refer to the programming flow chart in “Section 11.5 Alarm, 4 Programming
flow chart, 2) With alarm output (option)”. The default is “0” and no alarm output is available. Select an alarm type
and press . The cursor moves to the relay No. to specify relay Nos. for each alarm point.

screen. No output is available when
the relay No. is programmed to “0”.
The relay No. for AH is displayed as
“00”.
Program a relay No. from “0” to “n”.
The example is for programming to “3”.
Program “0” if no output is necessary.
The programming after this step or
before the alarm type selection, refer
to the flow chart in Section 11.5.

2).
The total numbers of alarm points are number
of channels x number of levels (4) + 2 (FAiL and
C. End). Number of output points is 6 or 12
points. (RD200: 6 points only) Place the cursor to the column of channel in
“Selecting alarm type” and press until
“FaiL” or “C. End” is displayed. In this condition,
select a relay No. to output when the corresponding
phenomenon occurs.
