Name:Electronic drain valve Material:Metal In / out port size: 1/2" flow aperture:5 mm Indicator lamp: LED indicating power on / off Voltage range: 10% for Protection grade: IP65 Insulation: class H Maximum working pressure: 1.6Mpa Maximum temperature: 90C Ambient temperature: -40C to 60C The largest current consumption: 4mA Power supply voltage: 24-240V AC/for DC 50/60Hz Discharge for time (ON): 0.5--10 seconds for Time interval (OFF): 0.5--45 minutes Application: Widely used in filters, separators, dryers, gas for tank, drip legs and other compressed air system components Installation 1. Clean the compressed air system before installation. 2. Note the direction of the for arrow when installing the for valve : outlet do not use the hose that not against the impact of air. 3. Power supply voltage should be consistent with the drain for valve voltage: the positive pole must be connected to connector "1" when using for DC. 4. When leave the factory the drain for valve has connected to the cable, brownness is fiery L,blue is the zero line N,yellow-green color is the safety ground wire GND. 5. Be sure to tighten the long screw on the terminal box to prevent water from burning. Warning! When installing the electronic drain for valve, make sure that: 1. Compressed air has been emptied (that is, under zero pressure). 2. The power supply has been switched off. Package Included: 1 x Electronic drain for valve
