measurement instruments. The instruments utilise gas sensors of various types with excellent repeatability, stability and long lifetime The devices are supplied either in duct-mount or wall-mount version. The wall mount version of the device is available with remote probe. The remote probe is connected to the main unit with shielded cable. Default connection cable length is 3 m. E2618 series provides two independent analog outputs OUT1 and OUT2, user- selectable to 4-20 mA or 0-10 V, proportional either to gas concentration or temperature. RS485 Modbus RTU digital communication interface allows easy instrument configuration and integration into various automation systems. A design with LCD indicator is available as an option. The version of your transmitter is marked on the package. 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, without aggressive gases in the atmosphere. See Specification table for more details. Installation and connections 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), 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. 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 on the next page for more information. 1. Wall mount version: Unscrew four lid screws and detach the lid from the transmitter. Attach the device to a wall with screws passing through mounting holes (see dimensional drawing below). Duct mount version: Cut 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 transmitter. 2. Use two M16 cable glands to pass the cables of the power supply and of the external devices. Attach the power cable to the device without turning it on. Using the connection diagram below, connect the analog outputs and digital interface terminals to the relevant devices according to your tasks. The screwless quick connect spring terminals on the E2618 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 8...9 mm and tin it, or to use the wire end sleeves. To connect the wire, insert the wire end into terminal hole. To disconnect, push the spring loaded terminal lever, pull the wire out, and release the lever. Use twisted pair cable, e.g. LiYY TP 2×2×0,5 mm2 or CAT 5, to connect the device to RS485 network. Use one pair for A and B wires and the second pair for common 0 V and power +U wires to connect the transmitter to Fieldbus network. Respect polarity. Overall length of all connections via RS485 interface should not exceed 1200 m. The type of each analog output can be independently changed between 4- 20 mA and 0-10 V with jumpers J1 (OUT1) and J2 (OUT2). With closed jumper the output is 0-10 V, with open jumper the output is 4-20 mA. By default both outputs OUT1 and OUT2 are assigned to gas concentration. The device has built-in temperature sensor which may be tied to any of the outputs. The output assignments and scales can be changed by Modbus commands. We recommend to set the difference between the upper and bottom limits of the output scale not narrower than 20% of detection range (for CO detectors the scales down to 5% of range are allowed). In any case, do not set the output scale below the tenfold resolution of the device. NOTE If you use a version with LCD, only OUT1 is available. 3. Turn on the power. The sensor heating up may take up to five minutes after switching on. During this period relays, analog outputs and Modbus interface are off. A LED placed on the PCB of the device allows to control the connection process. The LED response to different processes is presented in the table below. Process LED mode Sensor heating period Blinking 0.5 Hz (50% on, 50% off) Sensor absence or malfunction Blinking 0.5 Hz (90% off, 10% on) Modbus response The signal is modulated with short on-off pulses, even single Modbus cycle is traceable* Normal measurement Continuous light 4. Make sure that the transmitter is properly mounted, the external devices connected, power on and control LED is constantly lit. Place the lid back and fix it with the screws. The device is ready to use. It is recommended to keep the device on constantly, except for periods of maintenance and calibration, deplacement etc. Sensor probe handling The wall mount version of the transmitter is available with remote probe (see drawing below for dimensions). The remote probe is connected to the main unit with shielded cable. Default connection cable length is 3 m.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 may be replaced if it gets strongly contaminated. To replace the PTFE filter, unscrew the M25 nut and remove the old filter. Place a new filter into the nut and tighten it again. NB! Never stab or press the filter near its centre where the sensor is located since this may damage the sensor. The recommended orientation of sensor probe is vertical with the sensor tip pointing downwards. This prevents possible accumulation of condensed water on the sensor protection filter. The horizontal orientation is also suitable. Avoid upward position of the sensor tip. Configuring Gas transmitters E2618 share all functionalities of the PluraSens® multifunctional transmitter platform. The features and options include: - digital output change rate limiting filter - digital integrating (averaging) filter - temperature measurement channel with internal sensor - free assignment of each analog output to chosen parameter - flexible setting of analog output scales for each output - output shift and slope adjustment for calibration - Modbus controlled forced state option for analog outputs . E2618 can be configured through its RS485 interface by Modbus RTU commands. A standard configuration kit includes Model E1087 USB-EIA485 converter and a software pack.
