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.
3.3 Application in hazardous areas
3.3.1 USA, Canada
The DetCon detonation controller is certified by the CSA for use in a Class I, Division 2, Groups C
and D, T4 hazardous area in the USA and Canada. It is essential that you observe the
instructions of the CSA certificate 1401608 (LR 211392) (see Certification section).
The DetCon detonation controller can be supplied in a CSA-certified housing (P/N 43.00.102, P/N
43.00.202, P/N 43.00.120, P/N 43.00.220) or installed in an appropriately certified switch
cabinet and thus complies with the guidelines mentioned in the Certification section.
