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 have to 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 disconnect the wiring

 

Risk of destruction due to electrostatic discharge!

The DetCon detonation controller may only be installed into a control cabinet by specialized personnel who has been trained in handling ESD sensitive components and with due regard to relevant ESD standards. It is necessary to comply the ESD standard IEC 61340-5-1:2016 during installation. Damage caused by electrostatic discharge is not covered by warranty.

   

Operational safety!

The DetCon detonation controller requires high voltage ignition wires with integrated 5 k resistance, as otherwise interference in the detonation sensor signals may be caused. Any other ignition wires have to be replaced.

 

   

Operational safety!

Please note that the detonation sensors have to be wired according to the firing order of the cylinders. Refer to the section Wiring of the Detonation Sensors.

   

Risk of destruction!

The detonation sensor mounting screws have not to be tightened too firmly, as otherwise the sensors will be damaged and no longer function properly. Note the following specifications for sensor installation:

  • Tightening torque: 20 Nm ± 5 Nm (14.8 lb-ft ± 3.7 lb-ft) for mounting screws:
    • Cast iron engine block: M8 x 25 mm (0.98"), property class 8.8
    • Aluminum engine block: M8 x 30 mm (1.18"), property class 8.8
  • Tightening torque: 15 Nm ± 5 Nm (11 lb-ft ± 2.2 lb-ft) for mounting screws M6 x 30 mm (1.18"), property class 10.9 with sleeve

Also, lay the sensor cables in such a way that no resonance vibrations can occur on the cable. Otherwise, there is a risk of breakage.






 

Check parameter files

During the DetCon installation, it is necessary to check the settings in the parameter files. The knocking of the engine should also be checked in order to fine-tune the DenEdit settings. Especially the settings in the tab Outputs options have to be adjusted to on site specifications.

 

DetCon can only be used in single ignition operation

V engines can only use the DetCon detonation controller with single ignition, not in dual ignition operation.

The DetCon uses two time frames per cylinder to detect engine knocking. These time frames are opened in single ignition operation based on the ignition pulse. In dual ignition operation it is not possible to correctly assign the time frames to all cylinders.
