Page 28: Wire Probe (Gw100□W□□)
(2) Cut the probe vertically at the marking with a saw or grinder. Remove burrs with a metal file or sand paper. 5.5.2 Wire probe (GW100□W□□) (1) Remove 3 screws (M6, 5mm, pointed) on the weight with a wrench. (2) Pull the probe out of the weight. (3) Use tape on the probe where the probe is to be cut to keep the wire bundled. - Page 29 (5) Insert the wire to the weight. Make sure the marking is completely in the weight and not visible. In this state, the probe can be adjusted for about 20mm until the wire end touches the weight bottom. (±10mm of the point 65mm from the wire end) If the wire inside the weight is shorter than 55mm, the weight may drop off the wire.

Page 30: Mounting Sensor
5.6 Mounting Sensor 5.6.1 Location Observe the following, or faulty operation may result. <Metal tank/connection> Use metal connection and ensure electrical continuity between the sensor process connection and the tank. If the tank connection is metallic but smaller than φ200mm, then use a metal flange (≧100A/DN100) or an earth plate (≧φ200mm) to ensure electrical continuity. - Page 31 <Note on standpipe/nozzle design> Cut off the standpipe/nozzle extending into the tank. Ensure ample space around the mounting location for easy handling and maintenance. Ensuring space large enough for the overall length of the sensor is recommended for easy handling. Avoid proximity to inlets/outlets, agitators, or other sources of turbulence, or provide a metal stillpipe Make ensure electrical continuity between the stillpipe...

Page 33: Mounting
5.6.2 Mounting (1) Thread mounting WARNING Never hold the sensor by the housing to avoid damage. Use a tool on the hexagon to mount the threaded version. Take measures to prevent a leak from the process connection by using a gasket for example. Ensure electrical continuity between the sensor process connection and the tank at the same time. -
Page 34: Wiring
6. WIRING 6.1 Before Wiring (1) Disconnect power to the sensor. WARNING Disconnect power before wiring, or electric shock may result.
