Evikon E2610-LEL User manual

E2610 series gas detectors are compact and easy-to-use instruments.
The devices utilise 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 signalling or
ventilation control. Flashing LED and an internal buzzer give alarms at two set-
points.
Safety requirements
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.
Operating conditions
The device should be used in explosion-safe (non ATEX -rated) indoor areas at
the atmospheric pressure ±10% and 15...90 %RH without condensation
Avoid exposure to highly corrosive gases (H2S, SO2, HCl, Cl2 etc), or high
concentrations of basic gases, such as ammonia
Avoid mechanical shock or strong vibrations.
Avoid sources of electromagnetic interference
See Specifications table for more details
Installation
There are no precise rules or standards to follow when installing the 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
air flows etc),
detected gas (relative density to air, whether the gas is flammable, or toxiс, or
oxygen displacing, whether the gas is heated),
safety: strong vibrations, mechanical shock, and the sources of strong
electromagnetic interference should be avoided,
the device should be accessible for maintenance and repair.
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. Do not locate the detector close to
ventilation openings and strong air currents. Avoid the areas without air circulation
(corners, niches) as well. For general area monitoring without definite leakage
sources, the detectors should be distributed evenly in the room. For personal
safety control the detectors are installed in the breathing zone (at the height of the
head of people or animals). Recommended sensor position is vertical, pointing
downwards. See Installation guidelines section for more information.
The gas detector should be mounted on a wall at a place located in proximity to
possible gas source. Since carbon monoxide has practically the same density as
air, the detector should be installed in the breathing zone (1.5 m above the floor,
the height may vary depending on application) or near the potential leakage
source. Do not locate the detector close to ventilation openings and strong air
currents. Avoid the areas without air circulation (corners, niches) as well. The
device should be available for maintenance and repair.
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.
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 AC/DC source if you are using
detector version -24 or to 230 VAC 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 wire, loosen the screw, insert
the wire end into terminal hole and tighten the screw.

Attach terminal blocks to the board
4. Push enclosure to the base.
5. Turn on the power. It will take ca. 60 seconds after switching on for the sensor
to stabilize.
Operation
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 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, double acoustic and light
signal follows.
If 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 80% of the LOW alarm
setpoint.
If 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 80% 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.
Warranty
This product is warranted to be free from defects in material and workmanship for
a period of one year from the date of original sale. During this warranty period
Manufacturer will, at its option, either repair or replace product that proves to be
defective. This warranty is void if the product has been operated in conditions
outside ranges specified by Manufacturer or damaged by customer error or
negligence or if there has been an unauthorized modification.

Combustible gases
Combustible gas detector E2610-LEL is ntended for underground parkings, boiler
houses, kitchens, and other areas, where potentially e plosive concentration of
combustible gases can accumulate. The detector is sensitive to light hydrocarbon
gases (acetylene, methane, propane, butane) and hydrogen.
See Anne for more detailed information concerning the prorerties of the detected
gases.
Installation guidelines
(See Installation and connections section for general information.)
For gases lighter than air install the sensor higher than potential leakage/generation
source or near the ceiling. Combustible gases lighter than air are hydrogen (0,07 of air
density), methane (0,55 of air density) and acetylene (0.90 of air density).
Propane and butane are heavier than air (1.55 and 2.0 of air density respectively) and
tend to sink. It is recommended to place the sensor lower than potential leakage or
generation sourse.
Calibration
E2610-LEL detectors have been calibrated by Manufacturer with standard gas
mi tures before delivery. Provided that the sensor is used under moderate
conditions, field recalibration is recommended once a year. Please contact your
dealer for more information.
Maintenance
Do not perform any maintenance operation with the power on.
Clean the device with soft damp cloth. Do not use any abrasive cleaning agents.
Do not immerse the device into water or any cleaning media.

Combustible Gases Detector E2610-LEL ser Manual - Annex
Properties of gases
Acetylene
Synonyms/Trade Names: Ethine, Ethyne
Colorless flammable gas lighter that air. Mi tures with air are e plosive.
Results from the interaction of calcium carbide with water. In industrial production,
acetylene is mainly manufactured by the pyrolisis of light hydrocarbons.
Acetylene is widely used for welding and cutting of metals. The usage of acetylene
as a feedstock in chemical industry declines due to cost and environmental
considerations.

Butane
Butane is colorless flammable gas heavier than air. The term “butane” is used for
any one of two structural isomers (n-butane or isobutane, with unbranched and
branched chain respectively) or for their mi ture.
Occurs in light petroleum fractions.
Butane is used mainly as a fuel and as a feedstock in organic synthesis. It is
applied also as a propellant in aerosol sprays and may be used as ozone-friendly
refrigerant.
Mi tures of butane with propane and other hydrocarbons are referred to as LPG
(liquefied petroleum gas).
