12 COMMISSIONING
Please make sure the following checks are made before commissioning,
—
Ensure all the wiring connections are correct and wire diameter is suitable.
—
Ensure that the controller DC power has fuse, and
controller’s positive and negative and start battery
are correctly connected.
—
Emergency stop input is connected to the posi
tive pole of starter battery via emergency stop button’s
normally closed point and fuse.
—
Take proper actions to prevent engine from cranking successfully (e. g. Remove the connection wire
of fuel valve). If checking is OK, make the start battery power on; choose manual mode and controller
will executive routine.
—
Set controller under manual mode, press “start” button, and genset will start. After the cranking times
set before
, controller will send signal of Start Failure; then press “stop” to reset controller.
—
Recover the action to prevent engine from cranking successfully (e. g. Connect wire of fuel valve),
press start button again, and genset will start. If everything goes well, genset will be normally running
after idle running (if idle run is set). During this time, please watch
engine’s running situation and AC
generator’s voltage and frequency. If there is something abnormal, stop genset and check all wiring
connections according to this manual.
—
Select the
AUTO
mode from controller’s panel, and connect mains signal. After the mains normal
delay, controller will transfer ATS (if set) into mains load. After cooling time, controller will stop genset
and make it into “at rest” mode until there is mains abnormal situation.
—
When mains is abnormal again, genset will be started automatically and enter into normal running,
then controller send signal to make generator switch on, and control the ATS transfer into generator
load. If it is not li
ke this, please check ATS’ wiring connection according to this manual.
