◦ The GCB will take on the same state as it has before the critical mode has been
◦
enabled.
Critical mode during start request
The generator supplies the load and the GCB is closed. If critical mode is enabled, the
MCB will be operated according to the configured transition mode (parameter
).
The GCB will be opened without unloading (transition mode interchange or parallel). The
"Critical mode" message is displayed on the display screen and all shutdown alarms
become warning alarms.
• Critical mode ends before the start request is terminated:
•
◦ The engine continues running and a change to generator or parallel operation is
◦
performed.
◦ All shutdown alarms will become active again.
◦
• Start request will be terminated before the critical mode is terminated:
•
◦ The critical mode operation is continued.
◦
◦ The engine keeps running until the conditions for the critical mode are no
◦
longer fulfilled and all shutdown alarms will become active again.
◦ If the genset was not running before critical mode has been enabled, it will be
◦
stopped after cool down time (parameter
) has expired.
Critical mode during islanded operation
The busbar is supplied by the generator and emergency run (parameter
disabled. If the critical mode is enabled, the GCB will be opened although the MCB is not
enabled. This will cause a dead busbar.
