2.3 Special Safety Instructions for the Device
High voltage! Danger to life!
There is danger to life while the engine is operating due to high voltage. The
following safety instructions must therefore be observed when the engine is
running:
– Do not touch the ignition sensor unit (ISU)
– Do not remove the ignition sensor unit (ISU)
– Do not loosen the wiring
Risk of destruction due to electrostatic discharge!
The DetCon detonation controller may only be installed in a switch cabinet
by qualified personnel trained in the handling of ESD-endangered
components, observing the ESD regulations. The ESD standard IEC 61340-51:2016 must be observed during installation. No warranty is given for
damage due to electrostatic discharge.
Operational safety
The DetCon detonation controller requires high voltage ignition wires
with integrated 5 kΩ resistance, as otherwise interference in the detonation
sensor signals may be caused. Any other ignition wires must be replaced.
Risk of damage
The detonation sensor attachment screws must not be tightened too firmly,
as otherwise the sensors will be damaged and no longer function
properly.Observe the following information for sensor mounting:
– Torque: 20 Nm ± 5 Nm (14.8 ± 3.7 lb-ft) for mounting screws:
– made of cast iron: M8 x 25 mm (0.98"), Strength: 8.8
– made of aluminium: M8 x 30 mm (1.18"), strength: 8.8

Operational safety
Please note that the detonation sensors must be mounted according to the
firing order of the cylinders. Refer to the pertinent section Wiring of the
Detonation Sensors on page 57.
Detonation detection
The DetCon detonation controller detects knocking as far as possible, but
not bindingly.
DetCon only usable in single ignition mode
V-engines can only use the DetCon detonation controller with single
ignition and not in double ignition mode.
The DetCon uses two time windows per cylinder to detect engine knocking.
These time windows are opened in single ignition mode based on the
ignition pulse. In double ignition mode it is not possible to correctly assign
the time windows to all cylinders.
2.4 Proper Disposal
After the expiration of its service life, MOTORTECH equipment can be disposed of with other
commercial waste, or it may be returned to MOTORTECH. We will ensure its environmentally
friendly disposal.

ustion
The graphics
show the desired type of
combustion of the gas/air mixture in the
combustion chamber. The ignition spark
ignites the gas/air mixture. The flame front
spreads out evenly in the combustion
chamber with the specific laminar flame
speed of the gas/air mixture. The cylinder
pressure increases slightly during
combustion.
Knocking Combustion
Knocking combustion arises if the gas/air
mixture self-ignites before the actual flame
front, but after the ignition
. This system
does not detect so-called early ignition.
The reason for this is an excessive increase
in pressure and temperature of the as yet
non-combusted mixture due to the pressure
and temperature fronts preceding the normal
flame front. The pressure and temperature
fronts arising from the self-ignition, in turn,
make further self-ignitions possible. Highfrequency pressure waves arise in the
combustion chamber, which are introduced
into the engine structure via the walls of the
combustion chamber and released as airborne noise into the environment. The
knocking becomes audible in this way
.
Compared to normal combustion,
significantly higher peak pressures arise,
which may lead to major engine damage in
addition to the higher thermal load.

The task of the DetCon detonation controller is to avoid engine damage from knocking
combustion.
Vibration occurs in the engine compartment during the combustion process. These have a
frequency which is characteristic for the engine type. The DetCon measures the vibratory energy
within a narrow frequency range which is typical for the respective engine. The energy measured
is proportional to the knocking level.
Measurement is only carried out within operating cycles in which combustion is possible. This
increases the sensitivity of the measurement and minimizes its reaction to random noises. The
operating cycles are determined according to application and the ignition controller used via an
auxiliary synchronization output, an ignition sensor unit (ISU) or a camshaft sensor.

3 Intended Use
16 Rev. 02/2019
The measured knocking energy (Knocking Level curve) is compared in every cycle with a preset
maximum value (IGNITION REDUCTION LIMIT). If this maximum value is reached, the binary
output ENGINE KNOCKING is activated. At the same time, the analog outputs change their values
(Timing Reduction curve). The rate at which the value of the signal changes is specified by the
setting Timing Reduction Gain. The analog signals are transmitted to the ignition controller, thus
adjusting the ignition timing. If this causes the knocking energy to fall below the maximum
value, the values at the analog outputs are also reduced. The rate of this reduction is adjusted
according to the preset value Decrease Ramp.
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 load reduction via this output.
LOAD REDUCTION is deactivated again if the engine knocking stops. However, the analog
outputs remain active for a further period which is set via the function Delay after load reduction.
This period must be longer than required for reaching full load.
The third binary output, i.e. TRIP, is activated when the knocking exceeds the maximum value
IMMEDIATE STOP LIMIT. This can be used as an emergency stop signal to force the engine to stop.
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..

3.2 Applications
The DetCon detonation controller can analyze two-stroke and four-stroke engines with up to 20
cylinders and up to a maximum 1 kHz ignition frequency. The device is available in two versions:
– DetCon2 for two detonation sensors
– DetCon20 for up to 20 detonation sensors
Both device types are available as a built-in device for a control cabinet or with a CSA certified
enclosure. The following manual applies to both device types. Any differences between the two
versions are clearly identified.
In order to define the time frame for potential knocking, the detonation controller must know the
ignition timing of the first cylinder in the firing sequence. Depending on the application and the
ignition controller used, this can be determined in different ways:
– Gas engines:
– MOTORTECH ignition controllers with auxiliary synchronization output ASO (e. g. MIC6)
The ignition timing is determined via the signal on the ASO output. No other sensor is
required.
– Ignition controllers without ASO output:
The ignition timing is determined using a signal from the ignition sensor unit (ISU)
connected between the ignition output and the ignition coil of the first cylinder
– Diesel and pilot injection engines:
– The fuel injection timing is determined using the signal from an inductive camshaft
sensor.
Any use other than the one described in the operating manual shall be considered improper use
and will result in the voiding of all warranties.
