B.8 Additional maintenance
Furthermore in addition to the standards checks according to the manual following points of the
generator have to be checked:
• automatic shut down of the generator in case off high heating temperature
This shall be done by disconnecting the thermo-switch of the heat sink. Next to the rectifier you
will find a 2-pole connector. If you disconnect this connector from the opposite socket, the gene-
rator shall shut down – or, when the generator is not running you will get a signal on the panel.
Temperatures of the rectifier and heating
• Apply a thermocouple meter to the heat sink and the copper bars and monitor the maximum
temperatures of the rectifier.
• With the help of the infrared thermometer you can check all the temperatures on the rectifier.
Check all the cable connections of the DC- wiring. The easiest is to touch them carefully with
your finger. If they are getting warm or getting hot, these connections are poor and shall be re-
placed.
The temperature of the heat sink shall never exceed 95°C.
The temperature of the copper bars shall never exceed 120°C
