The EGMX and EGLX explosion-proof gas detectors have been developed
to continuously measure the ammable gas in the air. The EGMX model is
designed to measure the amount of methane gas in the range of 0-60% LEL.
The EGLX model is designed to measure the amount of LPG in the range of
0-60% LEL. EGX gas detectors are compatible with EGP series panels. Eight
explosion-proof gas detectors are connected to control panel directly. If more
connection required 4-20mA input module must be used.

This section describes the detector mounting. Please do not start the
mounting process without understanding the system, its parts and the
working principle of the system.
It is recommended to start the assembly after reading the warnings and
points to be considered.
WARNING
Anti-static measures should be taken before touching electronic materials.
Installation and maintenance must be done by authorized personnel.
Errors that may cause damage after an intervention to the device without
reading the entire user manual may exclude the device from the warranty.
Wall Mounting
First, open the detector cover.
Do the wiring of the places where 20mm cable glands will be installed.
Find the 2 mounting locations indicated by A shown in gure 1.

Detector
15-25cm
Choose a clean and smooth wall at eye level.
Be careful to install it in an area where there is no air ow, no fans and no
vibration.
It is not recommended to be installed close to radio frequency devices.
Make sure that it is installed in a suitable area for calibration and
maintenance.
For detector mounting, mount it from the necessary places using
M3x30mm screw and Ø 6mm plastic socket.
It is recommended to mount the LPG detector at 15-25cm and methane
detector at 0-10cm (Figure 2).

Cabling
Labels and cable functions should be stated in the cablings made.
A proper cabling should be supplied for electrical terminals.
You can reeve the cables from the holes in the lower box for 4-20mA
cabling
and Relay cabling.
8 connections can be made to control panel directly to the control panel.
If more connection is required 4-20mA input module must be used.
Cable Properties
The cable to be connected between detector and panel should have 1.5mm2
horizontal cutting at minimum and absolutely include ground cable. For
each connection, maximum cable length should be 400m.
Recommended cable: 18 AWG three conductor, insulated, stranded,
shielded copper cable
