3.3 Extending the Connection Cable
If it is necessary to extend the cable, a suitable junction box and
the correct length of 6-core cable are required. Connect the
junction box as shown in Fig. 3.3.
3.4 Jetwash System Connections
The electrical supply to the jetwash system pump or solenoid
valve is connected to the analyzer relay used for automatic
cleaning – see Fig. 3.4. The analyzer controls the frequency of
the wash sequence and the duration for which the cleaning
solution flows.
The analyzer outputs are held during a cleaning sequence.
Note.
Junction box (part no. 7690/049) is recommended.
6-core cable, part no, 7690054/XX (where XX is the
cable length, from 5 to 50 meters, in 5 meter
increments) is recommended.
Cable 7690054 is identical to that fitted to the sensor.
See Fig. 3.2 for cable end preparation instructions.
