Inhibit
Disables the alarm when ...
No generator frequency
The generator frequency is below 10 % of the nominal frequency.
Controller under SWBD
control
The
Local > Mode > Switchboard control
digital input is activated, OR a system problem forced the
controller under switchboard control.
ACM wire break
All these conditions are met:
•
The generator breaker is closed
•
Voltage is detected by one set of ACM voltage measurements
•
No voltage is detected on a phase, or on all three phases for the other set of ACM voltage
measurements
Inhibit 1
The
Alarm system > Inhibits > Activate inhibit 1
digital input is activated.
Inhibit 2
The
Alarm systems > Inhibits > Activate inhibit 2
digital input is activated.
Inhibit 3
The
Alarm systems > Inhibits > Activate inhibit 3
digital input is activated.
