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.
24 VAC or 230 VAC power supply options are available.
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 at the atmospheric             
pressure ±10% and 15...90 %RH without condensation 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 (the instrument is intended for leakage control.)
●Properties of the space under investigation (room geometry, direction, and         
velocity of airflows, etc.),
●Carbon monoxide has practically the same density as air and spreads evenly in            
the room. Install the sensor in proximity to possible leakage or generation source,            
taking into consideration the temperature of the gas, the air currents in the room,             
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.

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             

automatically if the gas concentration drops below 80% of the LOW alarm setpoint.
If the gas level exceeds the HIGH alarm setpoint, the bottom red LED starts flashing and               

Depending on the selected release mode, the HIGH alarm stops automatically or can be             
