7.1 Ignition Timing Reduction
The DetCon has two analog outputs for ignition timing reduction:
– 4-20 mA current loop
– 0-5 V voltage output
Both analog outputs operate simultaneously. Use the output designated for ignition timing
reduction for the ignition controller you are using (if necessary, ask the manufacturer of the
ignition system).
The analog outputs change their values and thereby retards the ignition timing as soon as the
IGNITION REDUCTION LIMIT has been exceeded. This limit is specified via the DenEdit software.
In addition, the software is used to determine the extent to which the ignition timing is retarded
(
Timing reduction gain ) and how quickly the ignition timing retarding is reset when knocking is
not longer detected (
Decrease ramp
). The retarding of the ignition timing can be limited using
the analog outputs via the
Maximum output value
.
7.2 Load Reduction
If the ignition timing can no longer be corrected via the analog outputs and the engine is still
knocking, the binary output for load reduction (
LOAD REDUCTION ) is activated. A master control
(e.g. ALL-IN-ONE) can control the engine power via this output.
LOAD REDUCTION is deactivated again if the engine knocking stops.
7.3 Engine Stop
The binary output
TRIP
is activated when engine knocking exceeds the maximum value
Immediate stop limit . This value is specified via the DenEdit software. The output can be used as
an emergency stop signal.
Checkbox Enable bad sensor detect
Activate the checkbox so that faulty knock sensors are indicated by the BAD
SENSOR status display. This function only detects sensors that supply
faulty signals. If there is a cable break or a sensor does not supply a signal
at all for any other reason, this is not indicated. If a faulty sensor is
detected, the binary output TRIP is also switched..
