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 positive 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 onload. 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 like this, please check ATS wiring connection according to this manual.
