This button places the module into its AUTO MODE. This mode allows the module to 
control the function of the generator automatically. The module monitors numerous 
start requests via digital input, PLC and MSC link and when one has been made, the set is 
automatically started. Once the generator is available, the module automatically instructs 
the generator to synchronise and once in sync, to be place the generator on load (‘Close 
Generator Output’ becomes active). Upon removal of the starting signal, the module 
starts the Return Delay Timer and once expired, the load is automatically ramped off the 
generator and then it is taken off load (‘Close Generator Output’ becomes inactive). The 
generator then continues to run for the duration of the Cooling Timer until it stops. The 
module then waits for the next start event.

This button is only active in the STOP/RESET mode, MANUAL mode. Pressing the Start 
button in Stop/Reset Mode powers up the engine’s ECU but does not start the engine. This 
can be used to check the status of the CAN communication and to prime the fuel system

Used for navigating the instrumentation, event log and configuration screens.

Used to silence the audible alarm in the controller, de-activates the audible alarm output  
(if configured) and illuminates all of the LED on the module’s facia as a lamp test function.

Close Generator – The Close Generator button controls the operation of the generator 
load switch and is only active in the Manual Mode once the generator is available. Pressing 
the Close Generator button when the generator is available and off load automatically 
instructs the generator to synchronise and once in sync, to be place the generator on load 
(‘Close Generator Output’ becomes active). If the generator bus is dead (has not supply 
on it) the generator is placed on load immediately. Further presses of the Close Generator 
button have no effect.

Open Generator – The Open Generator button is only active in the Manual Mode and 
allows the operator to open the generator load switch. Pressing the Open Generator 
button when the Generator is on load, automatically ramps the load off the generator and 
then takes it off load (‘Close Generator Output’ becomes inactive). Further presses of the 
Open Generator button have no effect.
