Onan Genset Genset Maintenance
9.8 Genset Shut-Down Codes
Background The genset controller includes built-in diagnostic capabilities. Through the blinking
of the light indicator on the control switch, a genset fault may be diagnosed. After a
fault shutdown, the indicator light will blink a code that indicates the type of fault.
The indcator light will repeatly blink 1, 2, 3, or 4 blinks at a time.
„
One blink signifies a shutdown due to a high-temperature condition.
„
Two blinks indicates a shutdown due to a loss of engine oil pressure.
„
Three blinks indicates a shutdown due to a service fault.
Each type of service fault is indicated by a second-level shut-down code. When
the indicator is blinking three blinks, pressing Stop will cause the two-digit, sec-
ond-level shut-down code to appear. (Pressing Stop again will stop the blinking.)
The two-digit codes consist of 1, 2, 3, 4, or 5 blinks, a brief pause, 1 to 9 blinks,
and then a long pause. The code then repeats. For example, shut-down code
36 appears as:
blink-blink-blink —pause— blink, blink, blink, blink, blink, blink —long pause—repeat
„
Four blinks indicates that engine cranking exceeded the preset time without
the engine starting. The preset time is 20 seconds when the ambient tempera-
ture is above 0°C (32°F); 30 seconds when the ambient temperature is below
0°C (32°F).
Note
„
Be careful not to interpret first-level shut-down faults numbers 3 and 4 as
second-level shut-down codes “33” and “44”, which have not been asigned as
shut-down codes.
„
The genset controller stops the diagnostic fault blinking after five minutes. To
resume the blinking, press and release Stop three times rapidly (within three
seconds).
„
The last fault logged will blink, even after the condition that caused the shut-
down condition has been corrected.
