Microprocessor Controller Features
Microprocessor controller features include the
annunciator panel lamps, analog meters, switches and
controls, fuses, and terminal strip. The following
paragraphs cover each of these topics.
Lamps
Auxiliary Fault. Lamp flashes or lights when fault is
detected.
Flashing Lamp Conditions
D The auxiliary lamp flashes immediately if the
controller senses no AC output while the
generator set is running (except duringthe first
10 seconds after start-up). The flashing stops
and the light is off when AC output is sensed.
No manual reset is required.
D The auxiliary lamp flashes if the battery power
was reconnected or was low and then came
back up again while the generator set master
switch was in the RUN or AUTO position. A
temporarily low battery condition where the
batteryisweakorundersizedfortheapplication
is a possible cause. To clear this condition,
place the generator set master switch in the
OFF/RESET position.
Continuous On Lamp Conditions
D The auxiliary lamp lights and generator set
shuts down immediately if the emergency stop
switch is activated (if generator set is equipped
with optional emergency stop shutdown
switch).
D The auxiliary lamp lights if the optional
emergency stop switch is reset while the
generator set master switch is in the AUTO or
RUN position. Place the generator set master
switch in OFF/RESET position to clear this
condition.
D The auxiliary lamp lights and engine shuts
down 5 seconds after high oil temperature
(P1-13) or auxiliary delay shutdown (P1-15)
faults occur (if so equipped). Theseconditions
areinhibited duringfirst 30seconds aftercrank
disconnect.
D The auxiliary lamp lights and engine shuts
down immediately if an overvoltage condition
occurs (if equipped with overvoltage shutdown
kit).
D The auxiliary lamp lights and engine shuts
downimmediatelyif activatedbyanycustomer-
supplied sensing devices connected to
auxiliaryimmediateshutdownports (P1-17and
P1-18).
Low Oil Pressure. Lamp illuminates if generator set
shuts down because of low oil pressure. Shutdown
occurs 5 seconds after engine reaches pressure
shutdown range.
Overcrank. Lamp illuminates and cranking stops if
engine does not start after 45 seconds of continuous
cranking or 75 seconds of cyclic cranking. See Auto
Starting.
D Crankingstopsandovercrank lampilluminates
after 15 seconds if starter or engine does not
turn (locked rotor).
D Overcrank lamp flashes if speed sensor signal
is absent longer than one second.
NOTE
The controller is equipped with an automatic
restart function. The generator set attempts to
restart if the engine speed drops below 13 Hz
(390 RPM). Continued decreased engine speed
causes an overcrank fault condition.
Overspeed. Lamp illuminates if generator set shuts
down because governed frequency on 50 and 60 Hz
models exceeds 70 Hz (2100 RPM).
Analog Meters
AC Ammeter. Meter measures amperage from output
leads. Use selector switch to choose output lead
circuits.
AC Voltmeter. Meter measures voltage across output
leads. Use selector switch to choose output lead
circuits.
DC Voltmeter. Meter measures voltage of starting
battery.
Frequency Meter. Meter measures frequency (Hz) of
generator set output voltage.
Hourmeter. Hourmeter records generator set total
operating hours for reference in scheduling
maintenance.
