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.

E2610-VOC Rev 24.03.2021
Installation guidelines
There are no precise rules or standards to follow when installing gas detectors. The following points must be taken into account:
● Application (the instrument is intended for leakage control.)
● Properties of the space under investigation (room geometry, direction, and velocity of airflows, etc.),
● Solvent vapors are heavier than air and tend to sink. Consider, if the vapors are heated or not if the detector is used for fire safety (LEL range) or air quality control
(0...100 to 0...1000 ppm range), etc.
● 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).
Rev 24.03.2021
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.
12
E2610-VOC 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 power 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 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 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 the 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-VOC 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.
