DESCRIPTION
DESCRIPTION OF ALARM
A01
Engine temperature pre-alarm (analog sensor)
Occurs if engine temperature rises above the pre-alarm threshold set in P09.05.
A02
Engine temperature high (analog sensor)
Occurs of engine temperature rises above the alarm threshold set in P09.06.
A03

Occurs if the resistive temperature sensor is in open circuit (disconnected).
A04

A09
Oil pressure low (digital sensor)
Occurs if low oil pressure is signalled by activation of the digital input programmed for this function.
A10
Digital pressure sensor fault
Occurs if the engine has stopped for over one minute, but the oil pressure sensor has not closed its contacts to
signal no oil pressure. It is assumed that the sensor is disconnected.
A11
Fuel level pre-alarm (analog sensor)
Occurs if fuel level falls below the pre-alarm threshold set in P10.04.
A12

Occurs if low fuel level is signalled by activation of the digital input programmed for this function.
A15
Battery voltage high
Occurs if battery voltage remains above the threshold set in P05.02 for longer than the time set in P05.04.
A16
Battery voltage low
Occurs if battery voltage remains below the threshold set in P05.03 for longer than the time set in P05.04.
A17
Battery discharged
Occurs if engine start attempts have reduced battery voltage below the minimum threshold.
A18
Battery charging alternator fault
Occurs if the engine is running (generator voltage and/or frequency or ‘W / pick-UP’ signal detected) but the battery
charging alternator signal (D+) remains under the engine running voltage threshold set in P11.01 for more than 4
seconds.
A19
“W / pick-up” signal fault
Occurs if speed control is enabled and the engine is running (battery charging alternator signal or generator voltage
and/or frequency signal detected) but no ‘W / pick-up’ engine speed signal is detected within 5 seconds.
A20
“W / pick-up” low engine speed
Occurs if the engine is running (battery charging alternator signal or generator voltage and/or frequency signal
detected) and is not decelerated, but the ‘W / pick-up’ engine speed signal remains under the threshold set in
P07.05 for the time set in P07.06.
A21
“W / pick-up” high engine speed
Occurs if the ‘W / pick-up’ engine speed signal remains over the threshold set in P07.03 for the time set in P07.04.
A22
Start failure
Occurs if the engine has not started after the set number of start attempts.
A23
Emergency stop
Occurs if power is removed from the teCOM1 or if a digital input programmed to function as ‘Emergency
stop’ is activated.
A24
Unexpected engine stop
Occurs after the alarm activation delay if the engine stops of its own accord, without the controller having
commanded the shut-down.
A25
Stop failure
Occurs if the engine has not stopped 65 seconds after the beginning of the stop cycle.

Occurs if asymmetry between the generator phases exceeds the threshold set in P12.07 for the time set in P12.08.
A31
Generator maximum current
Occurs if current from the generator exceeds the percentage threshold set in P13.01 for the time set in P13.02. If
this alarm occurs, wait for the reset time set in P13.05 before resetting it.

the feedback input for the generator switch / breaker.
A37
Maintenance request
Occurs when the hours of the maintenance interval reach zero. See menu M17. Use the Commands menu to reset
functioning hours and reset the alarm.
