1. GENERAL WARNINGS
1.1 PLEASE READ BEFORE USING THIS MANUAL
•This manual ispart of the productand should be kept near the instrument for easy and quick reference.
•The instrument shall not be used for purposes different from those described hereunder. It cannot be
used as a safety device.
•Check the application limits before proceeding.
•Dixell Srl reserves the right to change the composition of its products, even without notice, ensuring the
same and unchanged functionality.
1.2 SAFETY PRECAUTIONS
•Check the supply voltage is correct before connecting the instrument.
•Do not expose to water or moisture: use the controller only within the operating limits avoiding sudden
temperature changes with high atmospheric humidity to prevent formation ofcondensation
•Warning:disconnect all electrical connections before any kind of maintenance.
•Fit the sensor where it isnot accessible bythe End User. The instrument mustnot be opened.
•In case of failure or faulty operation send the instrument back to the distributor or to “Dixell S.r.l.” (see
address) with a detailed description of the fault.
•Consider the maximum currentwhich can be applied to each relay(see Technical Data).
•Ensure that the wires for sensor, loads and the power supply are separated and far enough from each
other, without crossing or intertwining.
•In case of applications in industrial environments, the use of mains filters (our mod. FT1) in parallel with
inductive loads could be useful.
•This unit must be installed by a suitably qualified technician who will install this unit in accordance with
these instructions and the standards in their particular industry/country. Operator of the unit should be
aware of the regulations and standards in their industry/country for the operation of this unit. These notes
are only intended asa guide and the manufacturer bears no responsibility for the installation oroperation
of this unit.
2. GENERAL DESCRIPTION
The XLH210 is a microprocessor controller suitable for for 4÷20mA gas sensors.
The alarm thresholds can be set with display visualization and recognized through Pre-Alarm and Alarm relay.
It has an RS485 serial output with RTU Modbusprotocol to monitorremotely the XWEB monitoring system.

3.1 WALL MOUNTING
1. Unscrew the 2 screws that keep connected the frontal and lower parts and separate the 2 parts
2. Unscrew the 4 frontal screws and remove the cover
3. Make the proper holes for cable-presses or pipe-presses using the centres signed in the bottom cover
(Fig. 1, H, I)
4. Make 3 holes in the wall, as indicated in Fig. 1 to fix the controller
5. Fix the cable-presses and the pipe-presses
6. Insert the wall-nugs, contained in the kit, into the holes made in the wall. Then use the o-rings and fix
the back partof the controllersby means of the 3 screws to the wall itself
7. Insert the wiring cablesin cable-presses or in the pipe-presses
8. Mount the frontal part using the previous 4 screws; do not press excessively in order to avoid plastic
deformation
9. After connecting the wiresto the terminal blocks close the cover (Fig.2, c) and fix itby the screws

5. GAS LEAK DETECTOR CONNECTIONS
The instruments are provided with screw terminal block to connect cables with a cross section up to 2,5 mm2.
Heat-resistant cables have to be used. Before connecting cables make sure the power supply complies with the
instrument’s requirements. Separate the sensor cables from the power supply cables, outputs and the power
connections. Do not exceed the maximum current allowed on each relay, in case of heavier loads use a
suitable external relay.
5.1 GAS SENSOR CONNECTIONS
For the functioning of the sensor, please refer to the manual provided by the manufacturer.

7. THE DISPLAY
7.1 TO ENTER IN PARAMETER CONFIGURATION
1) Enter the “Pr1” level where the parameters are visible;press ” SET + DOWN “ for more than 3 seconds.
2) Enter the “Pr2” level; Select “Pr2” (PAS) with
n
key and press “ SET ”.
3) On the display will appear “0 - -” with a flashing zero.
4) Use
o
or
n
to input the security code in the flashing digit; confirmthe figure by pressing “ SET ”.
The security code is “321“.
7.2 TO CHANGE PARAMETER VALUES
1. Enter the Programming mode.
2. Select the required parameter.
3. Press the “ SET ” key to display its value (thatstart blinking).
4. Use
o
or
n
to change its value.
5. Press “ SET ” to store the new value and move to the following parameter.
To exit: Press ” SET and then UP “ or wait 15s without pressing a key.
NOTE: the new values are saved even if the Programming Mode will exitby time-out.
7.3 HOW TO LOCK / UNLOCK THE KEYBOARD
+
Keep the oand nkeyspressed together for more than 3s until appear:
-“POF”= keyboard is locked
-“Pon”= keyboard is unlocked
7.4 ON/OFF
By pushing the ON/OFF key, the instrument shows “OFF” for 5 sec. and the ON/OFF LED is
switched ON.
To put the instrument in ON mode press another time the key.
8. MEANING OF THE LABELS

The alarm message is displayed until the alarm condition recoveries. All the alarm messages are showed
alternating with the room temperature exceptfor the “P1” which is flashing. To reset the “EE” alarm and restart
the normal functioning pressany key, the “rSt” message is displayed for about 3s.
9. KIND OF SENSORS
GAS: any model with 4÷20mA signal;maximum consumption not greater than 4V/A.
Note:
•The sensorscan be provided by Dixell with a differentP/N (the P/N depend on the gas type).Please
check with our sales department.
The sensorscan recognize the following gas: R134A, R410A, R407C, R404A, R507A, R407A, R407F
R744, R290.
The sensor can be IP41 or IP66. Please check with our sales department.
•There is a 5-minute power-up delay to allow the sensor to stabilise.
The green LED will flash at 1 second intervals during the warm-up.
•In an alarm condition:
ogreen LED stays on and the red LED is on
oaudible alarm operates(if not disabled and after delay, ifset).
orelay output activates (after a delay, if set)
oI output changes proportionally with gas concentration.
In a faultcondition:
ogreen LED will be offand the red LED will be on
ocurrent fault output will activate:2mA on the 4-20mA output
