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 setpoints.

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 (H

2

S, SO

2

, HCl, Cl

2

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 mm 2 . 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.

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 dualcolor 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.

Carbon monoxide

Colourless, odourless, and tasteless gas. Highly toxic.

Synonyms: Carbonous oxide, Carbon(II) oxide, Flue gas, Monoxide

Carbon monoxide is formed as a result of incomplete combustion of carboncontaining compounds, e.g. while operating a furnace, an oven or an engine when there is a limited supply of air.

Odourless

Highly toxic. Mild poisoning causes lightheadedness, confusion, headache, dizziness, and flu-like effects. Larger exposures can lead to toxicity of the CNS and heart, and death. After acute poisoning, long-term problems may occur. CO also have negative effects on a baby if exposed during pregnancy.

Chronic exposure to low levels can lead to depression, confusion, and memory loss.

(See Installation section for general information.)

Carbon monoxide has practically the same density as air and spreads evenly in the room. Install the sensor in a proximity to possible leakage or generation source, taking into consideration the temperature of the gas, the air currents in the room etc
