9.9 Alarm simulation register block (not CUE)
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. Whether the Simulation. AlarmCode register or the Simulation. WarningCode register is used makes no
difference. The pump will in both cases react according to the predefined reaction to the code in question.
For the complete list, see chapter Alarms and warnings.
Not all codes apply to all E-pump types.
