Chlorine containing refrigerants (CFC and HCFC) are considered to be damaging to the ozone layer
and contributing to the greenhouse effect. According to the Montreal Protocol, chlorine-containing
halocarbons should be completely dismissed and their manufacturing closed down.
Hydrofluorocarbons (HFC) contain no chlorine and are safer for the environment. Now
hydrofluorocarbons are the most commonly used halocarbon refrigerants.
Hydrofluoroolefins (HFO) is the last generation of refrigerants, more environmentally friendly than
HFCs, but moderately flammable (A2L Class).

Product description
E2610 series gas detectors are compact and easy-to-use instruments. The devices utilize
novel fully calibrated and temperature compensated gas sensors with excellent
repeatability, stability, and long lifetime.
Two relays with switch-over contact may be used for remote signaling or ventilation
control. Flashing LED and an internal buzzer give alarms at two setpoints.
Safety requirements
Misuse will impair the protection of the product. Always adhere to the safety provisions
applicable in the country of use.
Do not perform any maintenance operation with the power on. Do not let water or foreign
objects inside the device.
Removal of the PCB from the enclosure voids the warranty. Do not touch the electronic
components directly, as they are sensitive to static electricity.
Connection diagrams can be found in the connections section. The device might not
perform correctly or be damaged if the wrong power supply is connected.
External circuits connected to the equipment should have sufficient insulation rating
according to the environmental conditions and equipment power.
A disconnecting device that is marked as such and easily accessible should be included in
the installation of this product.
Operating conditions
The device should be used both in a non-hazardous indoor area and in a basic
electromagnetic environment, where the latter is defined in EN 61326-1. Avoid strong
mechanical shock and vibrations. Avoid corrosive atmosphere and areas highly
contaminated with dust, oil mist, etc. Keep the instrument away from direct sunlight. A
sudden temperature or humidity change might affect the sensitivity of the sensor.

Installation guidelines
There are no precise rules or standards to follow when installing gas detectors. The
following points must be taken into account:
●Application (air quality control or leakage detection)
●Properties of the space under investigation (room geometry, direction, and
velocity of airflows, etc.),
●Halocarbons are heavier than air and tend to sink. The sensor should be placed
near the floor.
●The device should be accessible for maintenance and repair.
The aforementioned conditions above will affect the coverage area of the device. however,
the coverage area for a detector is usually between 2.5 to 5 meters radius.
For early leakage detection install the sensor as close as possible to the potential leakage
sources (flanges, valves, pressure reducers, pumps, etc.), taking into consideration other
points listed above.
For general area monitoring without definite leakage sources, the detector should be
distributed evenly in the room.
Do not locate the detector close to ventilation openings and strong air currents. Avoid the
areas without air circulation (corners, niches) as well.
For personal safety control, the detectors are installed in the breathing zone (at the height
of the head of people or animals). The recommended sensor position is vertical, pointing
downwards.

Connections
1. Detach the base of the enclosure by gently pulling along four guiding pins.
2. Attach the base to the wall with two screws. (see drawings below).
3. Use rounded cutouts on the side of the base to let in the cables from the power supply
and of the external devices as shown below.

E2610-HFC Rev 24.03.2021
For easier connection, terminal blocks of E2610 series devices are removable. To dismount
the terminal block, pull it off from the PCB. Connect the power terminals N and L to the 24
V source if you are using detector version -24 or to 230 V AC mains if you are using
detector version -230 (see diagram below).
The terminals on the E2610 series devices are suitable for a wide range of wires with
cross-section 0,2...1,5 mm2. We recommend to strip the wire end by 5...6 mm and tin it, or
to use the wire end sleeves. To connect the wire, loosen the screw, insert the wire end into
the terminal hole and tighten the screw.
Connect external devices. Relay switch-over outputs may be used to control directly 24 V or
230 V (for versions -24 and -230 respectively) powered alarm sirens, ventilation fans,
shut-off valves, or other actuators. Attach terminal blocks to the board.
4. Push enclosure to the base.

Operation
Turn on the power. During the first ca.60 seconds after powering on E2610 performs a
warming-up and self-diagnostic routine, indicated by the flashing of each LED. The upper
dual-color LED remains continuously green in normal operation and blinks red in case of
device or sensor fault.
The warm-up time depends on the sensor type, unpowered period, and atmosphere. During
the first 30 seconds after powering on you may select the automatic or manual mode of
alarm release. By shortly (< 2 s) pressing the button on the device’s front panel you enable
the automatic mode, by pressing the button for 2...10 s — manual mode. The activation of
the automatic mode is followed by a single LED blinking and acoustic signal. If manual
mode is activated, the double acoustic and light signal follows.
If the gas concentration exceeds the LOW alarm setpoint, the bottom red LED starts
flashing at a rate of 1 Hz, and the relay RE1 switches over. The first alarm stops
automatically if the gas concentration drops below 70% of the LOW alarm setpoint.
If the gas level exceeds the HIGH alarm setpoint, the bottom red LED starts flashing and
the buzzer starts beeping at a rate of 2 Hz, and also the relay RE2 switches over.
Depending on the selected release mode, the HIGH alarm stops automatically or can be
stopped by pressing the button, on condition that the gas level has dropped below 70% of
the LOW alarm setpoint.
Beyond the warm-up period, holding down the button for 2...10 seconds and releasing
causes E2610 to reset and perform the self-diagnostic routine for testing purposes. When
holding the button down for over 10 seconds, E2610 imitates the reaching of the HIGH
setpoint with the respective light and sound indication and switching over the relays.
Maintenance
Do not perform any maintenance operation with the power on.
Clean the device with a soft damp cloth. Do not use any abrasive cleaning agents. Do not
immerse the device in water or any cleaning media.
Calibration
E2610-HFC detectors have been calibrated by the Manufacturer with standard gas
mixtures before delivery. Provided that the sensor is used under moderate conditions, field
recalibration is recommended every 12 months Please contact your dealer for more
information.
