-24 or to 230 V AC mains if you are using detector version -230 (see diagram below). The terminals on the E2630 series devices are suitable for a wide range of wires with cross-section 0,2...1,5 mm . We recommend to strip the wire end by 5...6 mm and use the wire end sleeves. -
Page 9: Operation
E2630-NO2 Rev 23.03.2021 Operation During the first ca. 60 seconds after powering on E2630 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. -
Page 10: Sensor Probe Handling
E2630-NO2 Rev 23.03.2021 Sensor probe handling 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 sensor head cap and remove the old filter. -
