A. Mode of Operation of the Generator
A.1 Mode of Operation of Operating Surveillance
Internal monitoring switches
The generator is equipped about failure switches, which are indicated on the remote control
panel, and also about failure switch, which switch-off the generator automatically without indica-
ting a failure in the remote control panel:
The remote control panel supervised the following values. In the case of a disturbance the gene-
rator is switched off, in order to avoid damage to the genset:
1. Cooling water temperature at cylinder head, at exhaust manifold and exhaust connection
2. Raw water and fresh water temperature
3. Coil temperature
4. Oil pressure
The fault is transmitted, if one of these switches measures a value that exceeds the required
value (all switches are openers). The current is switched off by the main relay. (Fuel magnet
valve closes, the fuel suction pump is switched off, VCS is switched off).
The combustion engine possesses an oil pressure control switch, which switches the engine off if
the oil pressure drops under a certain value.
The additional failure switch in the generator coil, it is also indicated at the remote control panel,
interrupts directly the current supply to the main power relay. By this constellation it is guaranteed
that the generator switches off in each case when an error is present.
This measure is, if possibly, a circuit at the remote control panel failed.
Thermo-switch at cylinder head
The thermo-switch at the cylinder head
serves the monitoring of the generator
temperature. All thermo-switches for the
generators from Panda 6.000 upward are
two-pole and laidout as "openers".
110°C and 130°C
