BUS TIE breaker controller inhibits
Inhibit
Disables the alarm when ...
Bus tie breaker closed
The
Breakers > Bus tie breaker > Feedback > BTB Closed
digital input is activated.
Bus tie breaker open
The
Breakers > Bus tie breaker > Feedback > BTB Open
digital input is activated.
Controller under SWBD
control
The
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 bus tie 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 system > Inhibits > Activate inhibit 2
digital input is activated.
Inhibit 3
The
Alarm system > Inhibits > Activate inhibit 3
digital input is activated.

The
Breakers, synchronisation and de-loading
chapter describes breaker handling and alarms in general.
The following table shows where to configure these alarms for the BUS TIE breaker, as well as which general alarm corresponds to
each BUS TIE breaker alarm.
