Chapter 2 │General Introduction
Purpose of the MX 43 controller
This controller is intended for the continuous measurement and control of the
gases present in the atmosphere.
Figure 1: Wall-mounted MX 43 and examples of the modules.
The system primarily comprises:
■ a wall-mounted MX 43 (4 or 8 lines) or rack-mounted MX 43 (8 lines);
■ 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.
Figure 2 presents a configuration example.

Chapter 5 │Digital Modules
This chapter presents the digital modules that may be installed on the MX 43
lines.
Addressable Digital Modules
These modules are connected on each of the available 4 or 8 lines of the MX
43, up to a limit of 32 modules on a version of 8-lines or 16 modules on a 4line version. The following table regroups the available modules:
Table 4: Addressable digital modules.
24
MX 43
User Manual
No portion of the bare end of the terminal wires should be visible.
For protection against any electromagnetic disturbances, the data
as well as screen wires (or braids) must be cut as short as
possible.
The incorrect installation of the cables or cable glands can cause
measurement errors or a malfunctioning of the system.
Do not lay the cables close to equipment such as engines,
transformers, or lines generating important magnetic fields.
It is recommended to always ensure a distinct separation between
these cables and the cables of other circuits.
All the digital modules on a line must be
identified by a unique address.
Switches 1 to 5 of the configuration block of
each module make it possible to establish an
address number (1 to 32) in binary mode.
In the illustration to the right, the address 9
(10010) has been defined.
The Addressing Table below lists the possible
combinations.

RS485 Transmission
General Topology of RS 485 Network
The digital modules are linked by 2 twisted cable pairs of 4 x 0.22 m²
minimum, type MPI-22A, nominal resistance of 120 Ohms. This cable carries
the RS485 (A and B) signal on one p air and the po we r supply of the modules
(0–24 VDC) connected to the line on the other pair. Shielding necessarily links
all the modules to the terminal block of MX 43.
The + 24 VDC, 0V, A, B terminals are respectively connected to +24VDC, 0V,
A, B terminals of the other modules on the line and then to the connector of
the corresponding line on the controller. The cable shielding must be
connected to the grounding rod of the MX 43.
At the end of the busbar, the 120-Ohm end of line resistor (EOL
RESISTOR/RESISTANCE F.D.L) must be activated (whatever the last module).

Introduction
A – Logic input connectors
Each of these two terminals (Figure 20, A) may be connected to a voltage-free
contact as per Figure 38. There is no alarm when the contact is open.
B – Module configuration switches
These switches are set according to the following table.
Table 6: Relay module configuration switches.
5 – Digital Modules
27
C: Relay configuration switches
The output status of each relay depends on the configuration of the switch
block (Figure 20, ref. C). Set the switch to ON (energized) or OFF (deenergized) according to the safety type desired; each switch acts on the relay
having the same number (switch 1 acts on relay 1). The contacts are
represented when no power and no alarm apply.
For the 4-relay module, only switches 1 to 4 are active.
E – Programmable relays
In its maximum configuration, the MX 43 can manage 24 external relays (or
24 modules with 1 stated relay or 3 modules of 8, all stated relays). The relays
are individually programmable. The operation of each relay depends on its
configuration.
Each of the 6 detector events [AL1 - AL2 - AL3 – High-range excess – Lowrange excess – Failure] can control one or several external or internal relays.
Several events can be assigned to the same relay.
Setting of relay parameters
The alarm limits governing the relays can only be set by the COM 43
application.
■ Normal: Relay operation as per the normal management of an alarm. (The
relay is launched only if the event exceeds the duration of the time lapse).
■ Buzzer function (releasable relays): The same as in normal operation,
with, in addition, the release of the relay even if the event is still present.
The time lapses are:
. Duration of maintenance: Minimum time of activation, adjustable from 0
to 900 seconds.
. Automatic release: If activated, the time is adjustable between 15 and
900 seconds, beyond which the buzzer relay is automatically released.
. Reactivation: If checked, time is adjustable between 15 and 900 seconds,
beyond which the buzzer relay is reactivated.
Controls of the alarm relay.
■ Logic equations of up to 4 levels of parentheses by the logic operators OR,
AND, NOR, and NAND. The result of the equation controls the relay.
■ Polling operations (x over y). There must be at least “x” events over the
total of “y” to activate the relay. Optionally, the user may define whether a
failure is considered an event in the same category as an alarm.
F – Relay status indicator
The status of each relay is visualized by a red LED (Figure 20, F):
■ LED off: Coil not powered.
■ LED lit: Coil powered.
G – Relay output connectors
The normal resistive load of each contact is 2A / 250 V AC or 2 A / 30 V DC.

1. Zero calibration
Inject standard gas to obtain 4 mA. Place the multimeter between points E
and D (Figure 24). If the value measured is different from 0 V, adjust C.
2. Sensitivity calibration
After injecting the gas, place the multimeter between points E and D
(Figure 24). If the value measured is different from 1.6 V, adjust B.
Should the adjustment value be different, calculate:
V= I (mA) x 0.10 (V/mA)
Example: If the current is 12 mA, “V” must be equal to 0.8 V.
If point E is not on the module use point G and add 1.2V to the measurement

6 – Wiring and Electrical Connections
33
The MX 43 does not have a start/stop switch.
Certain voltage levels are capable of causing serious injuries or even
death. It is advised to install the material and cabling before applying
live voltage.
Since an incorrect or poor installation may cause measurement
errors or system failures, it is necessary to strictly follow all the
instructions in this manual in order to guarantee the proper operation
of the system.
Chapter 6 │Wiring and Electrical Connections
This chapter details the electrical connections of all the system components
(MX 43, modules, additional equipment).
Controller Connection
The electrical connections must be carried out by qualified personnel in
compliance with the different directives in force in the country of installation.
Access to terminal blocks
■ In wall-mounted version: After unblocking the two locks, swing the front
cover towards the left in order to access the cabling terminal blocks (A).
■ In rack version: The terminal blocks are cabled from behind the controller
(B).

MX 43
User Manual
Sector Power Supply
The MX 43 can be powered from a 110-240 V AC source at 50/60 Hz, 1.5 A
max.
Check the nature of the current and the network voltage prior to any
connection. The electrical connections must be carried out with the equipment
disconnected.
The MX 43 must be protected upstream by a differential bipolar circuit breaker
with a type D response curve, size 4A. This circuit breaker must be included in
the electrical installation of the building, in the immediate proximity of the MX
43, and be easily accessible to operators. It shall be marked as the cut-off
device of the MX 43.
The sector power shall be connected to the terminal block as indicated in
Figure 28. The ground conductor shall be connected to the ground terminal
(B).
Figure 28: Connection of sector power in wall-mounted and rack-mounted versions.
External 24V DC Power Supply
The MX 43 can be powered from a 22 to 28 V AC source at 50/3.2 A, 1.5 A
max. In this case, connect the 24VDC source to the corresponding terminal
jack (Figure 29, A) respecting polarities. This jack is protected by Fuse F1.
Figure 29: Connection of 24VDC external power supply (A).
The main power supply charges the internal pack. The external 110-240 VAC,
24 VDC and battery pack sources can be used simultaneously, as there is
internal protection installed.
Integrated Backup Power Supply
The MX 43 can be equipped with a 24-VDC NiMh battery pack that maintains
power to the controller in the absence of the sector current or external 24VDC.
The batteries are charged by the mains supply (110-240 VAC).
The battery pack requires continuous charging for 7 days before reaching its
maximum capacity. Its autonomy depends on the MX 43 configuration.
6 – Wiring and Electrical Connections
35
If the battery pack is not installed at delivery, proceed as follows:
1. Position and fix the battery pack (A) at the place indicated using the 4
screws supplied.
2. Connect the battery pack connector to the connector (B) of the PCB. A
failsafe slot impedes any connection error.
Figure 30: Positioning the battery pack.
Earthing
The MX 43 is intended to be used in the parts of installations corresponding to
the category of overvoltage II and pollution degree 2 as per EN/IEC 60947-1.
In order to comply with this category of protection, it is absolutely necessary to
connect the ground terminal (Figure 31, A). Moreover, the cable braids of the
digital lines shall also be connected to this ground rod (Figure 31, A).
Figure 31: Ground connection through the ground rod.
Digital lines
The cabling of the digital lines connecting the controller to the different
modules deployed along the lines are the subject of the paragraphs
OLCT1ON Modules, 4- or 8-relay modules, 16-logic input modules, 8-analog
input modules and 4-analog output modules of this same chapter. It should be
remembered that this c able comes in 2 twisted pairs of 4 x 0.22 m² minimum,

6. USB Key
1. Configuration
Define the recording parameters on the USB key and view the storage
capacity remaining.
A 4G key can record approximately 18 months of information from an MX 43
comprised of 32 detectors with a sampling frequency of 2 seconds and up to
100 events per day and per detector.
■ Data Logging:
- Stop: stop recording measurements on the USB key. Stop the USB key
from recording before removing it in order to transfer the measurements
recorded that day from the MX 43 memory.
- Begins recording measurements on the USB key at the frequency
defined by the Sampling Rate configuration (see below). The USB key
icon appears at the top of the main screen (see Figure 44) when the USB
key is present and the unit has begun recording measurements.
■ Sampling Rate: selection of the frequency of recorded measurements –
2 sec, 16 sec, 30 sec, 1 min, 2 min or 15 min. At any frequency setting, the
MX 43 unit saves the measurements in the internal memory every 2
seconds. For example, if the recording frequency is set at 30 seconds, the
unit will record on the USB key an average value from the previous 15
measurements.
■ FIFO (First In, First Out): defines the action to be taken when the USB key
is full.
- Yes: the oldest recordings (measurements and events) present on the
USB key will be automatically erased.
- No: when the storage capacity in use reaches 80%, the MX 43 will
display the message Replace the key as soon as possible. Once the USB
key is almost full (98% of the storage capacity used) the alert message
USB key is full will appear. The message Recording impossible will
appear.
■ Fault Relay Activation: defines the state of the default relay once the USB
key is at 98%, absent when recording is activated, unformatted or in writing
error mode.
- Yes: the default relay is activated.
- No: the default relay is not activated.
■ Bargraph / Message: when the USB key is present, a bargraph is
displayed, showing the storage capacity in use. 100% indicates that the
key is full. When the key is not present but the measurement recording has
8 – Main Part Numbers
53
been set to Start, the message USB Flash is not present, is displayed in
place of the bargraph.
Figure 50: USB key configuration screen example.
2. USB files
Display the files present on the USB key, in chronological order of creation from
newest to oldest. Two types of files are present:
■ Events: files containing events saved on the USB key. Events include
alarms, errors or an acknowledgment request.
■ Data: files containing measurements saved on the USB key.
Figure 51: example of an event file and data from a USB key.
The window displays the following information:
■ Log Files xx of xx (ref. A): the number of Data and Event files that can be
opened on the MX 43 screen over the maximum number of files currently
saved on the key.

nd
■ 2
column (ref. C): name of the recording composed as follows:
- For an event file: events_JJMMAA_HH_MM.
- For a data file: data_JJMMAA_HH_MM.
Events and Data files are created automatically:
- At the beginning of the day (12:00AM);
- Every time the MX 43 is restarted.
■ Delete All: erase all of the files of the type s elected (data or events)
present on the key.
■ Delete: erase the file selected.
NB: every time the USB key is plugged in, two hidden files are automatically
created (Figure 51):

Chapter 11 | RS485 Digital Output
The MX 43 units using the RS485 Modbus option are equipped with a
communication card (code 6314114), which is affixed to the motherboard.
This card generates a RS485 output in Modbus RTU format.
Card description
Figure 52: the RS485 card.
The RS485 output can be configured using the COM 43 software, or using
unit menu 2.4 Program >RS485 Port (see page 45).

User Manual
Transfer Table
Two types of information can be retrieved via the RS485 output:
■ Information about sensor configuration;
■ Real-time sensor information (measurements, alarms, etc.).
1. Access to configuration information
It is possible to access the installation configuration (for example, to access
the alarm thresholds or the names of the sensors).
This configuration information is listed in the transfer table from address 0 to
address 1999.
The address of the detectors is determined as follows:
■ For a digital sensor:
Sensor address = (line number – 1) x 32 + slave number
■ For an analog sensor:
Sensor address = 256 + line number
Once the sensor address is known, the desired request can be executed by
following the transfer table below. For example, to find the instantaneous
alarm threshold number 1 for a sensor, read register number 52.
All of the information at addresses 1 to 52 will be accessed. The 52nd word
corresponds to the expected value.
Example
Access instantaneous alarm 1 for the sensor located on line 8 at address 2 of
unit 2.
A. Determination of the sensor address: (8 – 1) x 32 + 2 = 226.
B. Structure of the Modbus request:
- Slave number for the unit (defined by COM 43) 02 = 0x02
- Operating type (03 = read) 03 = 0x03
- Sensor address 226 = 0x00E2
- Number of words to read (see Excel document) 52 = 0x3A
- CRC
Thread: 0x02 0x03 0x00 0xE2 0x00 0x3A 0x65 0xDC
2. Access to real-time information
Measurement and alarm information from the detectors is listed in the transfer
table from address 2000 to 65535. The sensor measurements are available at
addresses 2001 to 2264, the sensor statuses are available at addresses 2301
to 2564 (alarm 1, alarm 2, etc.).
Example
Access to measurements from the sensor located at line 3 and address 32 of
unit n° 2.
A. Determination of the sensor address: (3 – 1) x 32 + 32 = 96.

management.
From addresses 2000 to 65535 the
address management is typical Modbus
address management.
- Slave number for the unit (defined by COM 43) 02 = 0x02
- Operating type (03 = read) 03 = 0x03
- Address of the 1st word 2000+96 = 0x0830
- Number of words to read 01 = 0x0001
- CRC
Thread: 0x02 0x03 0x08 0x30 0x00 0x01 0x86 0x56
Example
Access the status of the sensor located at analog input 5 of unit n° 2.
A. Calculation of the table index: 256 + 5 = 261
B. Request script:
- Slave number for the unit (defined by COM 43) 02 = 0x02
- Operating type (03 = read) 03 = 0x03
- Address of the 1st word 2300 + 261 = 0x0A01
- Number of words to read 01 = 0x0001
- CRC

Configuring sensors
Downloading the configuration
The MX 43 uses 256 external addresses (line #1 channel #1, to line #8
channel #32) and 8 analog channels for which the addresses are located from
257 to 264.
With the automated system, it is possible to send 264 (256 + 8) Modbus
requests, where the address field is numbered from 1 to 264 in order to
download the configuration of each sensor into the internal memory.
As a result of the operating functionality, it is only possible to repatriate the
data of a single sensor for interrogation.
If a sensor is stated at the address mentioned, the MX 43 sends the number
of data words requested; always from data #1: NAME OF ANALOG SENSOR,
at data #x.
If there is no information at the address mentioned, the MX 43 sends back 0.
