E-pump models H and I
9.8 Alarm simulation register block
Alarm simulation can be used to simulate alarms and warnings on
the E-pump. This is typically used when testing alarm event
handling in BMS/SCADA system controllers. A simulated alarm
will not cause the E-pump to stop running, but it will indicate the
alarm condition on the bus.
●: Always available.
H: Only available on model H and later versions.
3: Only available on MAGNA3.
