7. Pre-alarm and Shutdown Alarm
7.1 Pre-alarm (Warning)
NOTE: (Pre-alarms are non-critical failure conditions and do not affect the operation of the generator
system, they serve for drawing the operators’ attention to an undesirable condition so they can remove
it to ensure continuous running of the system. When Pre-alarms occur, the LED indicator flashes, but
failure will not be locked out and the unit will not shutdown. Once the Pre-alarm failure is removed the
Pre-alarm LED will automatically turn off.)

CHARGE FAILURE: After safety-on times up, if the charging voltage
from the excitation contact of alternator is lower than the “charge V
Pre-alarm”, the common failure LED indicator (
) flashes, the LCD
displays Charge failure icon:
BATT. UNDER VOLT: if controller detects that battery voltage has
fallen below the “Batt. Under volt”, common failure LED indicator
flashes. For example, “Batt. Under volt” preset as: 23.6V, when battery
voltage falls below this value, LCD flashing low value icon:
BATT. OVER VOLT: if controller detects that battery voltage has
exceeded the “Batt. Over volt”, common failure LED indicator flashes.
For example, “Batt. Over volt” preset as preset as: 28.2V, when battery
voltage exceeds this value, LCD flashing high value icon:
LOW OIL PRESS: if controller detects that the engine oil pressure has
fallen below the “Oil-P low preALM” after the safety-on timer expired,
common failure LED indicator flashes.For example, “Oil-P low preALM”
preset as: 2.2BAR, when engine oil pressure falls below this value,
LCD flashing low value icon:

common failure LED indicator flashes. For example, “Over SP
preALM” preset as: 1600RPM, when engine speed exceeds this value,
LCD flashing high value icon:
UNDER SPEED: if engine speed falls below the “Under SP preALM”
after the safety-on timer has expired, common failure LED indicator
flashes. For example, “Under SP preALM” preset as: 1440RPM, when
