The generator will run off load unless:
1. The mains supply fails,
2. A
Remote Start on load
signal is applied,
3. The
Close Generator
button is pressed.
If any of the above signals are received, the generator is synchronised and paralleled with the
mains supply (if available).
When in parallel:
A further press of the
Close Generator
button will transfer the load fully to the
generators, removing the load from the mains supply.
A press of the
Close Mains
button will open the generator load switching device,
transferring the load fully to the mains supply.
The generator will continue to run
on
load regardless of the state of the mains supply or remote
start input until the
Close Mains/Open Generator
button is pressed or the
Auto
mode is
selected.
If Auto mode is selected and the mains supply is healthy with the remote start on load signal not
active, then the
Remote Stop Delay Timer
begins, after which, the load is disconnected. The
generator will then run
off
load allowing the engine a
cooling
period.
Selecting
STOP (O)
de-energises the
FUEL SOLENOID
, bringing the generator to a stop.
NOTE:- When synchronising is enabled, the mains supply is checked before
closing any load switching device. If the supply is live, synchronising will take place
before any closure takes place.
NOTE:- Synchronising can be disabled if the application does not require this
function. Contact your genset supplier in the first instance for further details.
