Once the engine is running, the
Warm Up
timer (if selected) is initiated, allowing the engine to
stabilise before it can be loaded. The set is then synchronised and paralleled with the mains
supply, before the mains load switching device is opened.
The generator will continue to run
on
load regardless of the state of the mains supply or remote
start input until 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)
removes the Close Generator output (if configured) and 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. Contact your genset supplier in the first instance for
further details.
NOTE:- The module can be configured to run the set continuously in parallel
rather than transferring the load fully to the gensets.
NOTE:- Synchronising can be disabled if the application does not require this
function. Contact your genset supplier in the first instance for further details.
