Gen CCW Rot, Mains CCW Rot
The controller detects phase sequence on both generator and mains/bus
voltage terminals. These protections are important after controller installation
to avoid wrong voltage phase connection. There is a fixed defined phase
sequence in InteliCompact
NT
controller: L1, L2 and L3. When the phases are
connected in a different order (e.g. L1, L3, L2 or L2, L1, L3) alarms are
detected. These alarms prevent circuit breaker closing.
Adjust the setpoint WrnMaintenance to the interval of the next maintenance
check. The value of the setpoint will count down while the engine is running
and if reaches zero, this alarm will be issued. It will continue to count down
to negative values and the alarm message will remain in the alarm list (even
if the controller is switched off and on again) until the setpoint is re-adjusted
to a positive value.
Alarm: Charging alternator fail
This alarm is issued if the engine is running and the voltage on the D+
terminal is lower than 80% of the controller supply voltage. This alarm works
similar to the red “battery” alarm indicator on a vehicle dashboard.
The setpoint D+ Function has to be in CHRGFAIL or ENABLED position to
enable this alarm.
