The device switch for switching the detection module on and off is located on the top
right of the rear of the device (when viewed from the front). The device fuse and power
connection are located beneath it.
Communication with the basic module is performed via a 9 pin interface cable. The in-
terface of the rear of the detector is marked with "N-CLD".
The gas for producing ozone is connected to the "O
2
/air" quick-release connector on the
rear of the detector. The hose for the measuring gas coming from the basic module is
connected to the "sample in" gas inlet.
In order to equalize pressure differences caused by differing gas flows, it is possible to
use an absorber to allow air to enter the device. The absorber filters constituents from
the air which may distort the analysis.
The "service" interface is for service purposes only (monitoring function only). The trans-
mission data log of the detection module is output via this interface. A null modem cable
is required to connect. The programming button is also only for service purposes
(firmware updates).
