Error and Status Displays

The status displays indicate the status of the binary outputs and the error displays show errors which arise during the internal diagnostics check of the control device. The different lights of the displays indicate the following:
STATUS
- ENGINE KNOCKING
The selected knocking level Ignition reduction limit has been exceeded in at least one cylinder. The binary output Engine Knocking is activated. - TRIP
The knocking level has exceeded the value Immediate stop limit. The binary output Trip is activated. The engine is shut down if properly wired.
- REDUCTION
The maximum ignition timing reduction via the analog output signals has been exhausted. The value Maximum output value has been exceeded. The binary output Trip is activated. With proper wiring, a master control executes a load reduction.
ERRORS
- LOW RPM
This LED indicates that the speed is low and therefore the detonation control unit is not yet operative. - NO ISU PULSES
No pulses are detected at the ignition input (Timing). Either the engine has not started or the ignition sensor unit (ISU) has been wired incorrectly. - SPURIOUS PULSE
The pulses at the ignition input (Timing) are faulty. This can have the following causes: defective ignition sensor unit (ISU), incorrect sensitivity of the ignition sensor unit (check jumper Load Resistance), electrical interference, or noise.
Notice:
With long wire lengths, this LED occasionally flashes as a result of interferences. This does not indicate an error. - EEPROM FAULT
The parameters are incorrect as a result of an interference between the PC and the device. Try to reload the parameters. If this is not successful, the control device must be repaired. - BAD SENSOR
A faulty knocking sensor has been detected due to inconsistent signals. The display only lights up if the checkbox Enable bad sensor detect is activated in the tab Output options. This can have the following causes: the respective knocking sensor is loose, a wire has a loose connection, or the knocking sensor is not flush against the surface. You can see which knocking sensor is causing the problem on the tab Actual knocking values. The number of the failed knocking sensor is displayed in red.
