5. Control and Operation Instruction
5.1 Operation Mode Setting:
The controller has 2 modes: AUTO and MANUAL.
Operation Description
Press and hold the “AUTO” button for 2sec, the LED above the button
is illuminated; the controller is running in “AUTO” mode.
Press and hold the “MAN” button for 2sec, the LED above the button is
illuminated; the controller is running in “MAN” mode.
NOTE: Only 1 mode can be selected from above 2 modes.
5.2 AUTO control Sequence:
Controller is running in “AUTO” mode.
First of all, one of configurable inputs must be defined as Remote Start Signal.
When the remote start signal is active, the controller implements following procedure:
The Start delay timer is activated, when it times out the Preheat relay output is energized (if preheat
function selected), the timer starts. When it times out, the fuel relay output is energized, and operates the
fuel solenoid of the engine. After 300ms delay, the start (crank) relay output is energized; the start motor
engages and begins to crank. When the engine speed reaches the crank cutout RPM, the start relay
output is de-energized and the safety-on delay starts. When the safety-on times out, if the controller
detects that the parameters of the Genset such as voltage, frequency, oil pressure, coolant temperature
are normal, and no other failure is detected this indicates the Genset has successfully started and running
normally. The LCD displays the Genset Measuremen parameters.
When the voltage and frequency of Generator is normal, Gen. Normal LED illuminates, the timer for
Gen. On delay is activated, when it times out, GCB close/open relay closes,the transfer switch switches
on Gen. The Gen Aux. Switch’s contact feeds back a signal to a configurable input on our controller.
GCB closed LED illuminates.
NOTE:
When remote signal is active, the start-delay timer is activated. During
this period, if remote start signal is inactive, the start delay timer
terminates immediately; the controller will recovers to the original standby
status.
During cranking or idle period, if remote start signal is inactive, controller
stops the start procedure and recovers to original standby status.
