measurement cables [27] and the sensor measurement pick-up [28].
Picture 4: Sensor technology
1. Now the sensor measurement pick-up [28] (cover removed) should be installed on
the tank wall (preferably in the man hole shaft of the Graf synthetic tank). The
location of the mounted sensor pick-up should be between 10 and 15 cm above the
overflow [25]. The enclosed screws should be used to secure the device. After fully
tightening the screws, the points that are showing themselves on the outside of the
tank must be blunted to avoid injury [24].
2. Measure the height from the bottom of the tank [23] to the end of the terminals [15]
and [16] on the measurement pick-up [28].
3. Shorten the connection cable to suit the measured height.
4. Connect the sensor cable to the sensor as described in the following instructions:
Remove between 5-7 mm of the insulation from both of the cables. Next, pass the
red cable through the screw mounting 1 [19] and tighten this lightly, then connect
the red cable to the terminal [16]. The free white cable is now passed through the
screw mounting 2 [18] and tightened lightly, then connect the white cable to the
terminal [15].
