5 OPERATION
5.1 AUTOMATIC OPERATION (MULTIPLE SETS)
Auto mode is selected by pressing the button; a LED besides the button will illuminate
to confirm the operation.
Automatic Start Sequence:
Configure one of the 9 configurable input ports as
“Remote Start on Load Demand” using
PC software. Remote Start on Load Demand input indicates to the controller that it should
start the sets according to the pre-set priority procedure, and then, synchronize, parallel and
share load with any other sets in the system automatically.
1.
When “Remote Start” is active, “Start Delay” timer is initiated;
2.
“Start Delay” countdown will be displayed on LCD;
3. When start delay is over, preheat relay energizes (if configured),
“preheat delay XX s”
information will be displayed on LCD;
4. After the above delay, the Fuel Relay (or ECU output if configured) is energized, and
then one second later, the Start Relay is engaged. The engine is cranked for a pre-
set time. If the engine fails to fire during this cranking attempt then the fuel relay and
start relay are disengaged for the pre-
set rest period; “crank rest time” begins and
wait for the next crank attempt.
NOTE: If the unit has been configured for CAN Bus, compatible ECU‟s will
receive the start command via CAN Bus.
5. Should this start sequence continue beyond the set number of attempts, the start
sequence will be terminated, the first line of LCD display will be highlighted with black
and Fail to Start fault will be displayed.
6. In case of successful
crank attempt, the “Safety On” timer is activated, allowing Low
Oil Pressure, High Temperature, Under speed and Charge Alternator Failure inputs
to stabilise without triggering the fault. As soon as this delay is over, “start idle” delay
is initiated (if configured).
NOTE: If the unit has been configured for CAN Bus, speed sensing is via CAN
Bus.
7.
During “start idle” delay, under speed, under frequency, under voltage alarms are
inhibited. When this delay is over, “warming up” delay is initiated (if configured).
8.
In the case of a single generator system, after the “warming up” delay, if generator
status is normal, its indicator will be illuminated. If generator voltage and frequency
have reached on-load requirements, then the generator close relay will be energized;
