2General Introduction
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
The system primarily comprises:
■a
MX 16 controller
■One analog or digital detectors,).
The MX 16 instantly handles the measurements of detectors. As soon as the measurements reach
the configured thresholds, the internal buzzer and the LED indicators go on. At the same time, the
corresponding relays are activated to drive the additional actions programmed by the user.
Figure 2 presents a configuration example.

The different Versions
The MX 16 controller is available in 2 versions:
■1 line for digital detector:
- OLCT10N O2 (0-30% Vol.)
- OLCT10N CO2 (0-5;00% Vol.)
■1 line for 4-20mA analog detector:
- O2 (0-30% Vol)
- CO2 (0-5.00% Vol.)

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. Depending on the version of MX16, it is possible to connect either a 4-20mA analog
detectors or a digital addressable detector.

3Mechanical Installation
MX 16 Controller
Location
The 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.).
Attachment of the wall enclosure
Access 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.

Figure 5: Fixing the MX 16
Gas detectors
Refer to the manual supplied with each detector.

MX 16
ANALOG AND DIGITAL CONTROLLER
USER GUIDE

NP16EN
Revision: A.0
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.
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.

Zone Status Indicators (C)
The two bars of 7 indicators represent two zones. The detectors that are connected to the
controller can be assigned to one of the two zones by using COM 32 configuration software.
Each bar displays the status of the group of detectors of the pertinent zone as follows:
Icon Function
Orange indicator of high-range excess (OVS: overscale, high-range excess).
- Off: The measurement is lower than the OVS value programmed.
- Lit: The measurement is higher than the OVS value programmed. 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.

Press this key to silence the on-board buzzer and reset the alarms that can be acknowledged.
This reset button can be remote, see paragraph Remote Acknowledgement connector on page

Alarm Thresholds and Relays
It is possible to modify a programmed alarm level via the MX 16’s user interface ( Program menu).
Internal Relays and Buzzer
■2 Alarm relays are available. These relays are not configurable and are activated on the
appearance of any alarm.
■1 Fault relay is available. This relay is not configurable and is activated on the appearance of
any failure. The Fault relay is powered in normal operation mode so it does switch over in the
event of a power supply failure.
■The internal buzzer is activated on the appearance of any event (failure or alarm). The sound
differs depending on the event: continuous in fault mode, discontinuous in alarm mode and
frequency increases according to the alarm level that is reached. The internal buzzer can be
deactivated permanently through the user interface.
Alarms Settings
■2 alarm levels
■Each alarm is increasing (Toxic and Combustible gases) or decreasing (O2).
■Each alarm is configured as an instantaneous alarm without hysteresis.
■One over range alarm (OVS: over scale )
■One under range alarm (UDS: underscale )
■One “no ambiguity” alarm (for flammable gas detectors and concentrations above 100% LEL)
Alarms may be programmed for manual acknowledgement (except OVS, UDS, “no ambiguity”).
Alarms Manual Acknowledgement
In this mode, Alarms must be reset by the operator. Alarm management (relays, visual indicators,
