Magnetic flow switch UM3K-V

paddlefor liquidsreed switch

The devices function via the principle of a spring-supported paddle, and the magnetic triggering of a micro switch. Handling and Operation Note ●Include straight calming section of 5 x DN in inlet and outlet ●When tightening the union nut, the connection piece must be countered using an open-ended spanner (SW 19). ●If the media are dirty, install a filter (use magnetic filter for ferritic components). ●It must be ensured that the values given for voltage, current, and power are not exceeded. ●When switched on, a load must be connected in series. ●The electrical details apply to ohmic loads. Capacitive and inductive loads must be operated using a protective circuit Adjustment To adjust, open the slider. Adjustment is made using the adjustment screw with a lengthways slot; this is located under the valve. Turn clockwise for a lower switching point; turn anticlockwise for a higher switching point. After adjustment, close the slider again. Example: The adjustment range 20 to 27 l/min corresponds to 7 l/min Adjustment option in 7 revolutions. Adjustment is therefore 1 l/min for each revolution. Options ●Connection for round plug-in connector ●Signal lamp red or red/green in the plug DIN 43650-A ●Gold contact 125 V AC / 30 V DC, 100 mA ●Protective bellows ●Switching ranges for oil or gas ●Special values ●Adhesive PVC fitting Ordering information ●Specify direction of flow, medium, and switching range. ●For oils, state viscosity, temperature and designation (e.g. ISO VG 68) (enquire about range). ●For gases, state pressure (relative or absolute), temperature and medium (e.g. air) (enquire about range).
