The instruments utilize gas sensors of various types with excellent repeatability, stability, and long lifetime. E2608 series provides two independent analog outputs OUT1 and OUT2, user-selectable to 4-20 mA or 0-10 V. RS485 Modbus RTU digital communication interface allows easy instrument configuration and integration into various automation systems. Two relays RE1 and RE2 with closing dry contacts can be used to switch alarm sirens, ventilation fans, shut-off valves, or other actuators. Remote probe, duct mount version and 24 VAC or 230 VAC power supply options are available. The version of your detector-transmitter is marked on the package. If the symbol is marked on the equipment, consult the documentation for further information. 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 electrical 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 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. 6 Get In Touch Call: 01729 824108 Email: info@puravent.co.uk Our Address Puravent, Adremit Limited, 6 County Business Park, Darlington Road, Northallerton, DL6 2NQ E2608-O3 Rev 08.05.2023 Installation guidelines Before proceeding with the installation it is mandatory to read the Safety requirements section and make sure to comply with all listed instructions. Installation standards EN 60079-29-2 and EN 45544-4 are also recommended for further instructions and related information about the installation. During the installation of the detector-transmitter the following points must be considered: Application (air quality control or leakage detection) Properties of the space under investigation (room geometry, direction, and velocity of airflows, etc.), Ozone is 1.5 times heavier than air. Due to its high reactivity, the sensor should be located as close as possible to potential gas leakage or generation source. 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-transmitter 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-transmitters should be distributed evenly in the room. For personal safety control, the detector-transmitters are installed in the breathing zone (at the height of the head of people or animals). The recommended sensor position is vertical, pointing downwards. Wall mount version Attach the mounting lugs to the back of the detector-transmitter using the provided screws. Screw the device to the wall through the mounting lug holes (for dimensions see the drawing in the next section). Duct mount version Cut a hole with a diameter of 36...45 mm in the air duct at the chosen mounting place. Place the rubber flange aligning the holes in the flange and the air-duct and fix the flange with four self-tapping screws. Pass the sensor probe through the flange and adjust it to the appropriate depth. Unscrew four lid screws and detach the lid from the detector-transmitter. 7 Get In Touch Call: 01729 824108 Email: info@puravent.co.uk Our Address Puravent, Adremit Limited, 6 County Business Park, Darlington Road, Northallerton, DL6 2NQ E2608-O3 Mounting dimensions Rev 08.05.2023 Wall mount version with mounting lugs Duct mount version 8 Get In Touch Call: 01729 824108 Email: info@puravent.co.uk Our Address Puravent, Adremit Limited, 6 County Business Park, Darlington Road, Northallerton, DL6 2NQ E2608-O3 Rev 08.05.2023 Sensor probe handling The wall-mount version of the detector-transmitter is available with a remote probe (see drawing below for dimensions). The remote probe is connected to the main unit with a shielded cable. The default remote probe cable length is 3 m. A) Wall mount remote probe with fixing clamp (default version), B) Remote probe with rubber flange and three self-tapping screws (on request) The sensor probes of all types are equipped with a hydrophobic microporous PTFE filter to protect the sensor from dust, dirt, and water drops. The filter should be replaced if it gets strongly contaminated. To replace the PTFE filter, unscrew the sensor head cap and remove the old filter. Place a new filter into the cap and tighten it again. NOTE! Never stab or press the filter near its center where the sensor is located since this may damage the sensor. Do not remove the filter as it may cause the device to show incorrect values and/or break the sensor. The recommended orientation of the sensor probe is vertical with the sensor tip pointing downwards. This prevents the possible accumulation of condensed water on the sensor protection filter. Gas sensor replacement procedures 1. Remove the sensor head cap from the device (or the remote probe), 2. Remove the PTFE filter (if it is not removed within the cap), 3. Remove the O-ring rubber, 4. Detach the electrochemical sensor from the device, 5. Insert the new electrochemical sensor inside, 6. Put back the O-ring rubber, PTFE filter, and the head cap, respectively. 9 Get In Touch Call: 01729 824108 Email: info@puravent.co.uk Our Address Puravent, Adremit Limited, 6 County Business Park, Darlington Road, Northallerton, DL6 2NQ E2608-O3 Rev 08.05.2023 Electrical connections Unscrew four lid screws and detach the lid from the device. Use the M16 cable gland to let in cables of the power supply and of the external devices. Attach the power cable to the device without turning it on.

We recommend to strip the wire end by 8...9 mm and use wire end sleeves. To connect the wire, insert the wire end into the terminal hole. To disconnect, push the spring-loaded terminal lever, pull the wire out, and release the lever. Use a twisted-pair cable, e.g. LiYY TP 2×2×0.5 mm2 or CAT 5, to connect the device to the RS485 network. A and B on the device represent DATA+ and DATA- respectively, polarity must be respected when connecting to an external RS485 network. Both analog outputs can be independently changed between 4-20 mA and 0-10 V type using jumpers J1 (OUT1) and J2 (OUT2). By closing pins on a specific jumper the related output is 0-10 V, with an open jumper the output is 4-20 mA. Power restart is required after changing the position of the jumpers. NOTE! The outputs are not galvanically isolated from the external power supply and share a common 0V. Allowed load resistance limits are stated in the Specifications table. To power the instrument from an external power source, connect terminals 0V and +U to the source. If the integrated mains power supply module is used, connect terminals L and N to the mains. NOTE! Actuator short-circuits should be avoided, to protect the instrument relays using external fuses or safety switches. 11 Get In Touch Call: 01729 824108 Email: info@puravent.co.uk Our Address Puravent, Adremit Limited, 6 County Business Park, Darlington Road, Northallerton, DL6 2NQ E2608-O3 Correct and incorrect cabling for 24 VAC Rev 08.05.2023 12 Get In Touch Call: 01729 824108 Email: info@puravent.co.uk Our Address Puravent, Adremit Limited, 6 County Business Park, Darlington Road, Northallerton, DL6 2NQ E2608-O3 Rev 08.05.2023 Operation Turn on the power.
