3.2 TEST OPERATION
This mode is activated by pressing the pushbutton. An LED indicator beside the button
confirms this action.
Press the
button to begin the test sequence.
If the pre-heat output option is selected then the pre-heat timer is initiated, and the corresponding
auxiliary output (if configured) will energise.
After the above delay the Fuel Solenoid is energised, then ½ second later, the Starter Motor is
engaged.
The engine is cranked for a configurable period. If the engine fails to fire during this cranking
attempt then the starter motor is disengaged for the configurable rest period. Should this sequence
continue beyond the 3 cranking attempts, the start sequence will be terminated and Fail to Start
fault will be displayed.
When the engine fires, the starter motor is disengaged and locked out at 20Hz measured from the
Alternator output.
After the starter motor has disengaged, the Safety On delay is activated.
‘Delayed’ alarms (underspeed, low oil pressure etc) will be monitored after the end of the Safety
On delay.
The Warmup timer (if configured) is then followed.
NOTE:- The set will not be allowed to load until all delayed alarms indicate “normal”
operation. This prevents excessive wear on the damage that could be caused by loading
an engine with low oil pressure.
The load will be transferred to the generator and the set will run on load until Auto mode is selected
or STOP is pressed.
Selecting STOP (O) de-energises the FUEL SOLENOID, bringing the generator to a stop.
