At the installation of the BeCOMS
®
sensor SRE an one time calibration of the
incremental encoder has to be performed. This involves synchronising the neutral
point of the incremental encoder with the firing Top Dead Center (TDC) of cylinder
1 by finding offset between them.
It is important that the firing TDC is chosen at four-stroke engines, that is, when inlet
and outlet valves are closed.
The following procedure may only be executed by authorized personnel:
• Turn engine to firing TDC of first cylinder (number 1 at inline engine, A1 at
v-type engine), all valves must be closed!
• Go to Table 1 (page 4.10) IS Impuls Offset at the Evaluator menu
• Start Impuls Offset detection in the Evaluator menu
• Turn engine in normal rotation direction until Impuls Offset detection is finished
• Leaving IS Impuls Offset Table 1 (page 4.10), the offset will be stored in the
Evaluator’s EEPROM
• Restart Evaluator
• The syncronization procedure is done
Attention Syncronization must be repeated after all works that required the
mechanical connection between crankshaft and SRE sensor to be
opened!
