2. Evaluation of the measurement results: Notes

The test values for minimum and maximum current draw from the central locking drive measured at the ISID must be read from the characteristic curve.

For evaluation of the characteristic curve, the measured power consumption of the central locking drive must be examined in block operation. The power consumption in block operation must not exceed 3.3 A.

A current spike above 3.3 A on starting the central locking drive is permitted and is the normal operating condition.

The central locking drive is activated for 500 ms. A tolerance in the actuation time of +/- 50 ms is permitted and is the normal operating condition.

The following graphic illustration shows the current curves corresponding to intact and defective central locking drives.

The following graphic illustration portrays the current curves for a lock engagement and a lock disengagement process.

Depending on how the clip-on current measurement probe was connected around the two wire strands, the measuring result can be turned around 180 degrees. Either connect the clip-on current measurement probe the other way around or evaluate the characteristic curve offset by 180 degrees.
