2General Introduction
2.1 Purpose of the MX 16 controller
This controller is intended for the continuous measurement and control of the gases present in
the atmosphere.
Figure 1: MX 16 and examples of the modules
The system primarily comprises :
•a MX 16 ,
•one analog or digital detector.
The MX 16 instantly handles the measurements of detector. 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 MX 16 controller is programmed by using the COM 16 configuration software.Figure
2 presents a configuration example.

2.2 The different Versions
The MX 16 controller is available in Analog and Digital versions, configurable with COM 16 :
The MX 16 does not have an input for Wheatstone bridge sensors ( Wheatstone
bridge version ).
The MX16 does not manage MX 32 and MX 43 module as 8 analog input
(AIM), 4 or 8 relais modules (ROM), 16 logic inputs (LIM) and 4 analog outputs.
Figure 3: MX 16
The following table details the different possible configurations depending on the controller’s
version. On each line, it is possible to connect 4-20mA analog detectors or digital addressable
modules.

3Mechanical Installation
3.1 MX 16 Controller
3.1.1 LocationThe MX 16 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 MX 16 for opening the door. Use 3 fixing screws 4x25 mm for fixing
the case support.

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.

Configuration of Alarm Relays
Alarm relays are to be programmed with COM 16
software. The PCB printing displays while unpowered. R1 to R2
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 17).
•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:

Icon
Function

Orange indicator of high-range excess (OVS: overscale, high-range excess). This
value is adjustable up to 110% of the range.
•Off: The measurement is lower than the OVS value programmed.
•Lit: The measurement is higher than the OVS value programm
ed. The alarm
relays are activated in accordance with the program. In parallel, the display
indicates « > ».
OVS acknowledgement must be done manually and is only possible if the current
value drops below the programmed value.
Management of “Non-Ambiguity
Reading”
The Non-Ambiguity Reading function only applies to the monitoring of
flammable gases in a range of 0-100%LEL, and is subject to the decision of the
operator. Upon the detection of a concentration of gas higher than 100% LEL, the
LCD indicates > 100% LEL – Frozen value – High Concentration -
System in Fault
Condition . The OVS and FAILURE indicators are activated. Such an alarm can only
be deactivated by turning off the detector
via the maintenance menu once the
current gas level is below the programmed OVS limit.
