2General Introduction
2.1 Purpose of the MX32v2 controller
This controller is intended for the continuous measurement and control of the gases present in
the atmosphere.
MX32v2 8 relay output modules
and 4 4-20mA output
modules
Figure 1: MX32v2 and examples of the modules
The system primarily comprises :
•a MX32v2 (1 or 2 lines),
•different modules (analog or digital detectors, logic inputs, analog inputs, relay outputs,
and analog outputs).
The MX32v2 instantly handles the measurements of detectors and input modules. As soon as the
measurements reach the configured thresholds, the internal buzzer and the LED indicators go
off. At the same time, the corresponding relays are activated to drive the additional actions
programmed by the user.The MX32v2 controller is programmed by using the COM 32
configuration software.Figure 2 presents a configuration example.

3Mechanical Installation
3.1 MX32v2 Controller
3.1.1 LocationThe MX32v2 is intended for indoor use only and 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 (for instance: guardhouse, control room, or instrument room, etc.).
3.1.2 Attachment of the wall enclosureAccess to the controller must be
ensured in order to facilitate adjustments, monitoring, and cabling. A space of 400 mm is
necessary in front of the MX32v2 for opening the door. Use 3 fixing screws 4x25 mm for fixing
the case support.

Revision D.0
3.2 Gas detectors
Refer to the manual supplied with each detector.
3.2.1 Location
Each detector shall be positioned at ground level, on the ceiling, at human height or near air
extraction ducts, depending on the density of the gas to be detected or the application. 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.
3.2.2 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.
3.3 Digital Modules
For cabling and electrical information see paragraph
Wiring and Electrical
Connections on page 33.
LocationThe 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.

R.
Fault and Alarms relays (2 relays are located under the power supply; tag I). From
top to bottom:
•Fault (Fault relay, non-configurable)
•R1, R2, R3, R4 (alarm relays, configurable)
Configuration of Alarm Relays
Alarm relays are to be programmed with COM 32
software. The PCB printing displays while unpowered. R1 to R4 relays
can be
configured as normally energized
(the coil is powered when not in alarm) or
normally de-energized (the coil is powered when in alarm). There are different way
to program the relays:
•Normal mode: relay operates as the alarm sequence. The sure can set a delay
and chose the relay to be latched or unlatched (see Alarm Acknowledgement,
page 18).
•Buzzer mode: This mode is usually used for audible alarms management. The
‘buzzer’ relay acts as a ‘normal’ relay but can be acknowledged even if the
alarm is still present (in order to turn the siren off).
The time delays are:
. Reset Inhibit: Minimum time of activation, adjustable from 0 to 900 seconds.
. Automatic reset: Time adjustable between 15 and 900 seconds, beyond which
the buzzer relay is automatically deactivated.
. Reactivation time: Time adjustable between 15 and 900 seconds, beyond which
the buzzer relay is automatically reactivated if the alarm is still present.
Alarm Relay Management
by the logic operators OR, AND, NOR, NAND. Up to 4
levels of parentheses. The result of the equation controls the relay.
•Voting operation (x out of y): There must be at least “x” events out of “y” to
activate the relay. Depending on user’s programmation, a FAUT event can be
treated as an alarm event.
S. Relays status DEL indicator. Illuminated when the corresponding relay coil is ON.
