E2618-O2 Rev 08.05.2023 NOTE! Acid gases such as CO and SO will be absorbed by the electrolyte and tend to increase the flux of oxygen to the electrode. This gives an enhanced oxygen signal of approximately 0.3% of signal per 1% CO .
E2618-O2 Rev 08.05.2023 Product description E2618 series transmitters belong to the PluraSens ® family of multifunctional measurement instruments. The instruments utilize gas sensors of various types with excellent repeatability, stability, and long lifetime. E2618 series provide two independent analog outputs OUT1 and OUT2, user-selectable to 4-20 mA or 0-10 V, proportional to the chosen scale for gas concentration.
E2618-O2 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.

E2618-O2 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.
E2618-O2 Rev 08.05.2023 The screwless quick connect spring terminals on the E2618 series devices are suitable for a wide range of wires with a cross-section of 0.2...1.5 mm . We recommend striping the wire end by 8...9 mm and using wire end sleeves. To connect the wire, insert the wire end into the terminal hole.
E2618-O2 Rev 08.05.2023 Operation Turn on the power. The instrument warm-up time is about 1 minute for the O2 sensor, and 1 hour for the O2-5Y sensor after switching on, and the final sensor stabilization time to maximum accuracy takes about 30 minutes for O2 sensor and 12 hours for O2-5Y sensor. The operating status is indicated by the LED on the PCB of the device.
