List of checking procedures 2. Checks while engine is running and ship is stationary (gearbox in neutral) Engine temperature approx. 30 ° C Cable harness adapter is connected up to control unit Measure speed at the following operating points Check with MAN-Cats Monitoring 2 Measure voltage between PIN+ and PIN– with multimeter * “Br” button on EDC operating element for idle engine speed adjustment (51.11615–7169) 29 Set-point value Measured value Remark MAN-Cats RPM sensor (DZG) n lower idle speed n=................rpm PWG Min (low.
