High temperature. The thermocouple on the engine has failed. Kongsberg Troubleshooting

The No. 1 auxiliary engine has activated a high exhaust temperature alarm. In this article we will analyze the actions of electrical engineer to find and fix these problems.

In the exhaust system on the engine there are two thermocouples that measure the temperature at two points (A and B), these points correspond to their group of cylinders. The values at both points should be approximately equal (at 500°C), but the thermocouple at point B showed a temperature of 620°C and it continued to rise on the AMS monitor.
