2 Checking the usage Intended use Magnetic relief valve, open when de-energized, for the monitoring of gas valves for tightness used in conjunction with a visual discharge unit. For purging excess or leakage gas. This function is only guaranteed when used within the specified limits see page 6 (Technical data). Any other use is considered as non-compliant. Type code Code Description Magnetic relief valve Size: T T-product 0 0 ominal size [D] R Rp internal thread PT internal thread Quick opening, quick closing K Mains voltage: 4 V DC P 00 V AC, 0/60 Hz Q 0 V AC, 0/60 Hz Y 00 V AC, 0/60 Hz W 0 V AC, 0/60 Hz Position indicator: S with visual indicator G R L Part designations with visual indicator and gold contacts Viewing side: right left Electrical connection: M0 cable gland 4 Type label Solenoid actuator Valve block 4 Connection flange Connection box 6 Position indicator 6..S,..G Mains voltage, electrical power consumption, ambient temperature, enclosure, inlet pressure p u and installation position: see type label. D-4908 Osnabrück, Germany CE-006U64 WARIG The solenoid body heats up during operation depending on ambient temperature and voltage. Installation > +80 C > 76 F CAUTIO Please observe the following to ensure that the magnetic relief valve is not damaged during installation: Do not store or install the unit in the open air. Ensure that there is sufficient space for installation. Sealing material and thread cuttings must not be allowed to get into the valve housing. We recommend that a filter be installed upstream of every system. Do not use compression fittings. Do not clamp the unit in a vice. Only secure the connection flange by holding the octagon with a suitable spanner. Risk of external leakage. The actuator cannot be rotated on magnetic relief valves..s and..g. The housing must not be in contact with masonry. Minimum clearance 0 mm. Installation position: black solenoid actuator in the vertical upright position or tilted up to the horizontal, not upside down. -

3 Plug When installing two plugs on a with position indicator: label the sockets and plugs to avoid confusion. Wiring Use temperature-resistant cable (> 80 C). Disconnect the system from the electrical power supply. Shut off the gas supply. Wiring to E Preparing the wiring If the M0 cable gland or plug is enclosed, push through the knock-out for the cable gland then remove the cover. The cover must not be taken off before pushing through the knock-out as it prevents damage to the connection box. If the M0 cable gland or plug is already fitted, you do not need to push through the knock-out. First push through the knock-out then unscrew the cover! 4 Socket a Connecting a without position indicator LV (+) (-) M0 cable gland 6 LV (+) (-) LV (+) = black (-) = blue 7 8 8a = (-) = LV (+) -

CAUTIO Danger of interference between valve voltage and position indicator voltage. Route valve and position indicator cables separately through M0 cable glands or use two separate plugs. x LV (+) (-) Tightness test Close the solenoid valve.
