Application (load)
Automatic operation (Kerys in “AUTO” mode)
Loss of grid voltage
•
Generating set start request (dry contact, switch, clock, etc.).
• The speed and voltage of the generating set increase.
• Generating set power unit switched off after voltage and frequency stabilisation.
Return of grid voltage
•
Dry contact, switch, clock, etc. switched on.
• Cooling delay.
• Generating set stopped and set to standby.
FORCED OPERATION (Kerys in “AUTO” mode)
Start of FORCED OPERATION
•
Generating set start request (dry contact, switch, clock, etc.).
• The speed and voltage of the generating set increase.
• Generating set power unit switched off after voltage and frequency stabilisation.
The installation is supplied by the generating set
End of FORCED OPERATION
• Dry contact, switch, clock, etc. switched on.
• Generating set power unit switched on.
• Cooling delay.
• Generating set stopped and set to standby.
The Kerys remains in ”AUTO” mode
Manual operation of generating set
This mode of operation is selected with the “MANU” key (on the front of the MMI module). The operator is able to start and stop the
generating set by using the MMI keypad. The generating set power unit is switched off by means of the MMI keys. The safety devices
of the generating set remain active in this mode of operation.
This mode of operation is the responsibility of the operator.
