These instructions shall be used by qualified service personnel only,
who have been duly trained to install and maintain Gas detection
systems.
WARNINGS
Valid for all variants of IP and ATEX Gas detectors
•Do not install and connect the gas detector without carefully reading these
instructions. All operations must be executed by skilled personnel who are aware of
the regulations and has attended a technical training course on products included in
this manual.
•The housing must be earthed (grounded).
•Keep the sensor away from gas substances or solvents such as silicone and
derivatives, acetone, all types of paints, alcohol & derivatives, cleaning solvents,
turpentine, bleach, etc. These agents could damage the sensitive part of the sensor
or permanently change the original setting. Strictly avoid to test the sensors with
lighters or generic spray cans.
•When the sensor is outdoor installed, it’s necessary to put an adequate cover over
the sensor to avoid being directly wet by rain or snow.
•Do not install the sensor closed to vents, high speed air or vortexes.
•During the installation or maintenance of ATEX gas detectors, before opening the
housing, make sure that the power is OFF (either 24Vdc or current loop) and that
the application area is safe. Otherwise it’s forbidden to open the sensor and
execute connections.
•Do not disconnect any connectors or plug-in cards when the sensor is powered up.
•When the installation is completed, it’s necessary to execute the electrical tests on
the sensors by using the proper software, working with the simulation functions,
generating pre-alarm, alarm and fault conditions and checking the exact match in
the control panel or in any other device connected to the sensors
•For ATEX gas detectors it’s mandatory to read carefully the safety instructions
contained in the package.
•The Gas detector must be installed vertically with its nose facing down (see
pictures).
•Do not unplug the connector of the sensitive element when it’s powered and do not
power the sensor when the head is not available

•The installation height is determined by the type of gas to be detected. Here below
there are some examples; in case the type of gas is not included in this list, please
check the specific gravity to avoid installation errors.
•Examples:
•Heavy gases: about 30 cm from the ground (eg. Propane, gasoline vapors etc.)
•Light gases: about 30 cm from the ceiling (eg. Methane, Hydrogen, etc)
•The Oxygen and Carbon Monoxide gas detectors have to be installed mainly at ca.
1,60 cm from the ground.

Gas detector Moon series - Overview
The new generation of gas detectors Moon series is available with 5 different sensing
elements, in order to provide a very large range of Gas detection applications.
The sensor can be combined with 6 different Communication Interfaces that can be
selected according to the installation needs. Details and diagrams in the next pages.
The detector has been designed to give to the installer the possibility to check the sensor
parameters, set and change the sensor element, provide maintenance service directly on-
site, through a dedicated software application (Level 1 and Level 2).
Level 1
Access without password: it is possible verify the set parameters and make tests as
alarm, prealarm and fault simulations.
Only visualization
•Prealarm and alarm threshold
•Prealarm and alarm filters
•4-20mA working range
•Initialization delay
•Sensor life (working hours)
•Alarms number (only real alarms occurred during sensor life are counted, not
software simulation).
Level 2
Password protected: it is possible set the sensor, with the support of calibrated gas
cylinders, without any electronic adjustment trough trimmers or jumper, but easily
trough the software interface. Moreover it is possible finalize the sensor element
(head) substitution, even by software. This function is conform to the international
technical norms in order to protect the detector from external sabotage or setting
modification by not authorized personal.
The head substitution can be done only with a new one (same item). A different
head will generate a failure into the detector.
L2 Parameters editing
•Prealarm and alarm threshold
•Prealarm and alarm filters
•4-20mA working range
•Initialization delay
•Sensor element (head) substitution
•Calibration

Gas detector Moon series - G7(AP) E7(AD) product range
Description
Industrial gas detectors, available with IP55 metal housing or ATEX II 2G Ex-d IIC T6
housing. The detector is combined with two boards: the first card controls the sensing
element, and depends to the detected Gas type; the second one controls the communication
to the control device (see the table below) and it is available either for connection to specific
panels or for connection to normal electrical cabinets and PLC.
Sensors for automatic gas detection are generally suitable for explosion risks,
Hydrocarbons (L.I.E. detection), toxicity Ammonia, Carbon Monoxide (ppm detection) and
Oxygen control (% detection).

LIFE OF THE SENSORS
The average life of the sensors:
•Catalytic: in a clean environment the life can be of 3/4 years. In presence of
pollution, the average life is reduced and as well the sensitivity.
•Electrochemical cell: in a clean environment, the life can be of 2/3 years. In
presence of pollution, the average life of the sensor rapidly decreases.
•Semiconductor: in a clean environment the life can be of 3/4 years. In presence of
pollution, the average life rapidly decreases and the values reading is altered.
MAINTENANCE
•The Gas detectors maintenance is mandatory and it ensures the proper functioning
of the sensor.
•The maintenance has to be planned according to the installation site and to the
deterioration experienced by the sensors in the various environments.
•All operations must be executed in compliance with the relevant regulations in force.
