1. If the green READY LED of the Evaluator is off and the thermovoltage signal and/or RPM are displayed as zero or unstable on the LCD of the Evaluator (and in Data_Logger) at a running engine, then please conduct the following steps:
1) Check if cable connectors at the cable connecting SRE and the Evaluator are loose, if necessary, fix them
2) If this can not solve the problem, please check the error message reported and contact motcom GmbH or its authorized representatives.
2. If the green READY LED of the Evaluator is on, but only the thermosignal and no RPM is displayed on the LCD of the Evaluator (and in Data_Logger) at a running engine, then please conduct the following steps:
1) Remove the interface housing cover
2) Check whether the metal coupling inside is turning with the engine
Warning: Do not touch moving parts with tools or hands !!
3) If the coupling is broken it must be exchanged
after the engine is stopped
If it is not turning, retighten it with the necessary torque of 14Nm
after the engine is stopped. Take care all tools are removed prior to re start the engine.
4) If the coupling is turning, check if cable connectors at the cable connecting
SRE and the Evaluator are loose, and if necessary, fix them
5) Re-assemble the interface housing cover.
6) If you could not solve the problem, please check the error message reported and contact motcom GmbH or its authorized representatives
Attention
If you have retightened the metal coupling the synchronization steps in Chapter 5.2 SRE Mechanical Adjustments on page 5.2 must be done.
In this case, the re-synchronizsation of the SRE is mandatory!
