The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below.Problem
On certain Generator Sets the bearings or winding Resistance Temperature Device (RTD) may fail. The RTD set point may be incorrect on some Generator Sets.This failure may be displayed as an erratic reading, an unrealistic temperature, open in the RTD circuit, or short circuit.Solution
Do not operate or work on this product unless you have read and understood the instruction and warnings in the relevant Operation and Maintenance Manuals and relevant service literature. Failure to follow the instructions or heed the warnings could result in injury or death. Proper care is your responsibility.
Table 1 shows the stator winding coefficient and bearing RTD coefficient, for each frame family.

Identify if the failure is in the RTD or the RTD wiring.
Replace the failed bearing RTD.
The failed winding RTD cannot be replaced. The winding RTD should be disconnected and a spare used instead.
If the failure is within the RTD wiring, repair the wiring.Note: The wiring repair will require installation of new wire pins or soldering of the existing pins.
Correct the RTD module programming.Identifying RTD Module Loose Connections
Stator RTD (input 1 to 6)
There are two stator resistance temperature devices per phase connected to the RTD module. The Electronic Modular Control Panel (EMCP) will display the higher value.
