4.3. AUTO START/STOP OPERATION
Auto mode is selected by pressing the
button; a LED besides the button will illuminate to
confirm the operation.
Starting Sequence:
1. When the accumulator v
oltage has fallen below the “Charge Start Voltage” or when
“Remote Start (with load)” is active, “Start Delay” timer is initiated. “Start Delay”
countdown will be displayed on LCD display;
2. When start delay is over, preheat relay energizes (if configured),
“preheat delay XXs”
information will be displayed on LCD display;
3. After the above delay, the Fuel Relay (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.
4. Should this start sequence continue beyond the set number of attempts, the start
sequence will be terminated, and Fail to Start fault will be displayed on LCD display.
5.
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, “Waiting For Load”
delay is initiated.
6. If the on-load requirements have been reached, then the generator close relay will be
energized and the constant-current charge status is settled. The generator will regulate
GOV/AVR voltage automatically according to the charging current; If the GOV/AVR
voltage has reached its maximum value while the charging current is lower than the
“Rated Charge Current”, Charge Fault alarm will be initiated.
NOTE:
Charge Stop Mode
:
Charge Current + Volt. The accumulator charges the
genset with the preset rated charging current (charge type: constant current). When the
accumulator voltage has exceeded the
“constant voltage value”, enter into the “Constant
Voltage Charge” status. During the “Constant Voltage Charge” status, the accumulator
charges the genset with its minimum charging current as soon as the minimum value is
reached.
After the accumulator voltage has reached the “Charge Stop Voltage”, the
charging is finished and the ge
nset is enter into “Stop Mode”.
