•
Start of active power distribution.
•
Resumption of application at rated voltage and frequency.
The Kerys PLCs remain in “AUTO” mode
The installation is supplied by the generating sets

Manual power plant operation
This mode of operation is selected with the “MANU” key. This enables the operator to start and stop the generating sets one by one via
the MMI keypad. The generating set power unit is switched off manually with synchronisation of each generating set to the busbar
using the MMI keys “+F”, “-F”, “+V” and “-V”. The distribution of power among the generating sets remains automatic.
The safety
devices of the generating sets remain active in this mode of operation.
This mode of operation is the responsibility of the operator.
