High Engine Temperature (Shutdown Alarm –
Auto Reset)
A 10 second delay on start-up and one (1) second
delay before shutdown. Auto reset when the condition
clears and restart the engine if a valid start signal is
still present.
This switch’s contacts (Figure 3.6) close if the tem-
perature should exceed approximately 144° C (293°
F), initiating an engine shutdown. Once the oil tem-
perature drops to a safe level the switch’s contacts
open again.
Over Crank (Shutdown Alarm)
This occurs if the engine has not started within the
specified crank cycle. (See "Cranking" section.)

Over Speed (Shutdown Alarm)
4320 RPM for three (3) seconds or 4500 RPM imme-
diately. This feature protects the generator from dam-
age by shutting it down if it happens to run faster
than the preset limit. This protection also prevents
the generator from supplying an output that could
potentially damage appliances connected to the
generator circuit. Contact the nearest Dealer if this
failure occurs.
RPM Sense Loss (Shutdown Alarm)
During cranking, if the Control Board does not see
a valid RPM signal within three (3) seconds, it will
shut down and lock out on RPM sense loss. While
engine is running, if RPM signal is lost for one (1)
second the Control Board will shut the engine down,
wait 15 seconds, then re-crank the engine. If no RPM
signal is detected within the first three (3) seconds
of cranking, the Control Board will shut the engine
down and latch out on RPM sensor loss. If the RPM
signal is detected, the engine will start and run nor-
mally. If the RPM signal is subsequently lost again,
the Control Board will try one more re-crank attempt
before latching out and displaying the RPM sensor
failure message.
Under-frequency (Shutdown Alarm)
After starting, if the generator stays under frequency
for more than 30 seconds it will shut down. The
under-frequency setting is 50 Hz.
Internal Fault (Shutdown Alarm)
This alarm cannot be cleared, call service dealer.
CLEAR ALARM
8kW — Clear the alarm by setting the AUTO/OFF/
•
MANUAL switch to the OFF position and back to
AUTO.
10 - 20kW — Clear the alarm by setting the AUTO/
•
OFF/MANUAL switch to the OFF position. Press
the ENTER key to unlatch any active fault and
clear the corresponding alarm message.
3.6.2 WARNINGS
Second Priority (Non-latching) Displayed
on the
control panel and the external yellow LED (V-twins
only). Warnings automatically clear when the moni-
tored condition goes away. Warnings are recorded in
the alarm log. Warnings cannot cause shutdowns.
Low Battery
The Control Board monitors battery voltage and dis-
plays a warning if the battery voltage falls below 11.0
volts for one (1) minute. Warning is automatically
cleared if the battery voltage rises above 11.0 volts.
Battery voltage is not monitored during the crank
cycle.
Exercise Set Error
If the exercise period becomes corrupted, a warning
message will be displayed. This message will only
clear when the exercise period is reset.
