Installation, assembly and disassembly of the transmitter
Before assembling, read the valid installation standards ČSN EN 60079-29-2 (Selection, installation, use and maintenance of
detectors for combustible gases and oxygen) and ČSN EN 45544-4 (Guidelines for the selection, installation, use and
maintenance of detectors of toxic substances).
Make certain that the sensor input is accessible by air. The transmitter must be in an open area with no obstacles in its way
(furniture etc.) Ensure that the input of the sensor is not be polluted by layers of dust or otherwise contaminated. To maintain
IP protection, the transmitter must be mounted with the sensor down.
1. Assembly of the transmitter
The transmitter consists of four parts - the body of the transmitter, the removable sensor and bushings.
Transmitter assembly procedure is to be performed in the following steps:
a) Disassemble the transmitter using four hexagon socket 3mm screws
b) Use a screwdriver to break out holes for the bushings
c) Mount the transmitter on a flat surface using three 6mm fasteners in a height above the floor with the gas
entrance facing downwards, according to the specifications of the detected substance
d) Direct the cables trough the bushings
e) Connect the wiring to the terminal block of the transmitter
f) Assemble the transmitter using four hexagon socket 4mm screws

This activity must not be performed when the sensor is energized.
Should it be necessary to replace the sensor module with a new piece, unscrew and remove
the cover. Na senzorovém modulu odšroubujeme dvojici šroubů s vnitřním šestihranem
3mm a senzorový modul zapáčením zevnitř nástrojem vyjmeme. Opatrně nasuneme nový
modul - nesmí dojít k zohýbání pinů. Zajistíme dvojicí šroubů a nasuneme víko, které
zajistíme.
