4.3.5 The Operation Surveillance System

Thermo-switch at cylinder head
The thermo-switch at the cylinder head serves to monitor the
generator temperature. All thermo-switches for the genera-
tors from Panda 6.000 upward are two-pole (earthed), so cal-
led "openers". This means the contacts are open in normal
cases and close only when the limits have been exceeded.

Thermo-switch at water-cooled exhaust elbow
This Thermo switch is located at the water-cooled exhaust
elbow and serves to monitor the freshwater circulation
system. It takes a measurement at the warmest spot, since
the combustion gases are guided from the cylinder head to
the exhaust elbow.

If the impeller pump stops and delivers no more seawater,
the exhaust connection becomes extremely hot.
