Hysteresis can be set in the alarm setpoint.
Setting hysteresis prevents relays from chattering.
An alarm is output when the delay timer expires
after the alarm setpoint is reached.
0.00 to 99.59 (min, sec.) (enabled when alarm-
1 type “AL1” is 1, 2, 9, 10, 11, 12, 19, and 20)
0.00 to 99.59 (min, sec.) (enabled when alarm-
2 type “AL2” is
1, 2, 9, 10, 11, 12, 19, and 20
)
0.00 to 99.59 (min, sec.) (enabled when alarm-
3 type “AL3” is
1, 2, 9, 10, 11, 12, 19, and 20
)
0.00 to 99.59 (min, sec.) (enabled when alarm-
4 type “AL4” is
1, 2, 9, 10, 11, 12, 19, and 20

OFF (0)
1: PV high limit (energized, no stand-by action)
2: PV low limit (energized, no stand-by action)
9: PV high limit (de-energized, no stand-by action)
10: PV low limit (de-energized, no stand-by action)
11: PV high limit (energized, stand-by action)
12: PV low limit (energized, stand-by action)
19: PV high limit (de-energized, stand-by action)
20: PV low limit (de-energized, stand-by action)
21: Fault diagnosis output
Turns on in case of input burnout, A/D converter
failure, or reference junction compensation
(RJC) failure.
22: FAIL output
Turns off in case of program failure, ROM failure,
RAM failure, or power failure. This output is on
during normal operation. If it turns off, the
retransmission output is set to 0%, the alarm
output is set to OFF, and the indicator stops.
See “List of Alarm Types” for details on how these Alarm
Type parameters behave.
