Manual Shutdown
If the engine reaches a stable speed prior to automatic shutdown, the heating system can be shut down with the
HEATING OFF pushbutton switch (S101).
Overtemperature Shutdown
If the heating system overheats, temperature switch S110 opens. If S110 is open, K105 de-energizes:
+24 V is switched to R103 through N-C contact 30-87a.
The >0,5 A current produced by R103 triggers circuit breaker F103:
N-O contact 1-2 is open; K109 deenergizes and the HEATING ON indicator lamp (H101) goes out.
The HEATING FAILURE indicator lamp (H103) is connected to +Vreg through N-C contact 21-22, and lights up.
After every heating system shutdown (for any reason including a fault), time relay K107 remains energized for
about 90 seconds. This causes the heating system fan motor to continue running for about 90 seconds, since it is
connected to +24 V through N-O contact 15-18 of K107. This run-on function prevents hot air from building up,
thus preventing the heating system from overheating.

BATTLE SHORT function (K11) not activated.
1.14.2.1 Operating the Flame Glowplug System.
MASTER SWITCH (S1) in control cabinet assembly to ON:
+24 V is applied, through F1 to F9, to the control cabinet 24-V circuits.
BATTERY CHARGING CONTROL indicator lamp (H2) and OIL PRESSURE indicator lamp (H3) light up
(+Vreg from N5).
Auxiliary contactor K2 (fault message) energizes.
GLOWPLUG/START rotary switch (S2) to GLOWPLUG:
Flame glowplugs (1R5, 1R6) and fuel delivery solenoid valve (1Y1) are activated through R1.
After no more than 90 seconds, the GLOWPLUG ON indicator lamp (H1) lights up. The diesel engine can be
started.
1.14.2.2 Operating the Diesel Engine and Synchronous Generator.
GLOWPLUG/START rotary switch (S2) to START
Auxiliary contactor K28 energizes and latches through N-O contact 13-14.
+24 V is applied to connector 50 of the starter (1 Ml) via N-O contacts 13-14 and 23-24 of K2, and 1-2 and 3-4
of K28. The starter turns the engine at the speed required to catch, until it starts running under its own power.
K28 prevents the starter from shutting down.
Time relay K10 (oil pressure) energizes after a delay (delayed shutdown due to insufficient oil pressure).
