Alarm-3 type 1
OFF (0), 1 to 25, 28 to 31
1: PV high limit (energized, no stand-by action)
2: PV low limit (energized, no stand-by action)
3: Deviation high limit (energized, no stand-by action)
4: Deviation low limit (energized, no stand-by action)
5: Deviation high limit (de-energized, no stand-by action)
6: Deviation low limit (de-energized, no stand-by action)
These Alarm Type parameters are common to the
parameters 1.SP to 4.SP.
See “2.5 Changing Alarm Type” for other alarm types.
