Probable Faulty Locations
1)Malfunction of the EC input signal for detecting the sensor head position (I/O check NO.26 INPUT bitE (iSHRTC) or bitF
(iSHADC)).
2)Programming errorThe gauging subprogram was called without designation of M137.
Program Example:
M117 CALL OTFRD
Measures to Take
1)Recheck the program.
2)If the alarm is not related to the gauging cycle, check the EC input signal.
