2General Introduction
Purpose of the MX 43 controller
This controller is intended for the continuous measurement and control of the gases present in
the atmosphere.
Wall-mounted MX 43 Rack-mounted MX 43 EB type Cabinet
to remote
optional modules
Figure 1: Wall-mounted MX 43 and examples of the modules.
The system primarily comprises:
■a wall-mounted MX 43;
■different modules (detector with digital or analog output, logic inputs, analog inputs,
relay outputs, and analog outputs).
The MX 43 instantly handles the measurements of detectors and input modules. As soon as the
measurements reach the programmed limit, a sound and visual alarm are given. At the same
time, the corresponding relay or relays are activated, in turn controlling the additional internal
or external actions envisaged by the user.
The MX 43 controller is programmed by using the COM 43 application.

3Mechanical Installation
This chapter details the mechanical installation of MX 43 and the digital modules.
MX 43 Controller
3.1.1 Location
The MX 43 shall be installed in premises without explosive atmospheres, away from direct
exposure to sunlight, and protected from humidity, dust, and temperature variations. It shall
preferably be located in a monitored environment (guardhouse, control room, or instrument
room, for example).
3.1.2 Attachment of the wall enclosure
Access to the controller must be ensured in the front in order to facilitate adjustments,
monitoring, and cabling. A space of 400 mm is necessary in front of the MX 43 for opening the
door.
(*) rear fixing legs included.
Figure 4: Size of the wall-mounted version.

NPM43EN
Revision K.0
Use 3 fixing screws 4x25 mm for fixing the case support.
Figure 5: Fixing of the wall- mounted version MX 43 with a support plate.
3.1.3 Setting-up of a 19” Rack – 4 U
Access to the unit must be ensured in order to facilitate adjustments and monitoring, and
likewise in the back in order to allow easy access to the different connectors at the rear.
This rack is built into a bay or a standard 19” cabinet. You should leave ½ U (22 mm) of space
above and below the rack so as to assure the proper ventilation of the MX 43.
Figure 6: Size of the rack-mounted version.

Revision K.0 11
Digital Modules
The cabling is the subject of the paragraph Wiring and Electrical Connections on
page 37.
3.2.1 Gas detectors
Refer to the manual supplied with each detector.
Location
Each detector shall be positioned at ground level, on the ceiling, at the height of the respiratory
tract, or near air extraction ducts, depending on the density of the gas to be detected or
applied. Heavy gases are detected close to the ground, while lighter gases are present along
the ceiling. If necessary, contact TELEDYNE OLDHAM SIMTRONICS for any questions
regarding proper detector positioning.
Fixing
The detectors shall preferably be positioned in an accessible place so that inspections and
maintenance can be carried out as well as to ensure the absolute safety of the operators. The
detectors must not be obstructed by anything that will prevent them from measuring the ambient
environment to be checked.
If mounting an OLCT 10N on a vertical surface, position the cable gland downwards.
3.2.2 Other models
Location
The relay modules, logic outputs, analog outputs, and analog inputs are positioned depending
on the installation layout, mandatorily in places free from explosive atmospheres, protected
from humidity, dust, and temperature variations; for example in technical cabinets.
Fixing
These modules shall be mounted on
a DIN rail in a cabinet or in an
electrical cabinet.
For relay modules connected to low
voltage electrical parts, the
installation is carried out according
to the standards in force.
Figure 7: Fixing of a module (relay, logic outputs,
or analog outputs or inputs) on a DIN rail.
