TP-7070 8/20 35Section 2 Operation

2.10.1 Faults and Alarms

Press the Alarm (!) button shown in Figure 2-27 to view a

ist of generator set events, including status messages,

alarms, and faults.

 A status message communicates the state of the

generator set (example: appearance of Stop mode).

 An alarm (warning) signals an impending problem

(example: coolant temperature alarm). The alarm

button flashes orange. See Figure 2-28. A warning

(alarm) appears in orange on the screen and does not

cause the generator to shut down.

 A fault shuts down the generator set (example: oil

ressure fault). The alarm button flashes red. See

Figure 2-29. A fault appears in red on the screen and

causes the generator to shut down (instantly or

delayed, depending on the programmed incidence).

 A number on the alarm button indicates the number of

active faults and/or alarms.

There are some exceptions. A specific fault message on

the HMI screen may be processed as an alarm by the

PLC, so there is no engine shutdown.

Press the stop horn button. The horn (if equipped)

turns off and the stop horn button disappears. The alarm

button stops flashing and turns orange.

Press the alarm (!) button. A list of the last three active

alarms that have not been reset is displayed. See

Figure 2-30. Alarms and faults are listed in

chronological order.
