been fitted correctly. Replace the cover of the measurement pick-up and
secure this with the appropriate fastening screws.
7. The installation of the data cable [12] to the system control must be
according to good professional practice to constitute a correct completion
of the sensor technology: A protective cable conduit must be used. (The
data cable is not suitable for installing directly in the earth).
The end of the data cable that is still unconnected is fitted with a plug
connector. This is to be plugged into the appropriate socket
[8] of the
system control. Diagram 2 on page 3 makes clear the interrelation:
Note:
The red and the white cable going down to the probe should be straight and
smooth to be drawn taught by the weight of the stainless steel probe. The
stainless steel probe must hang just above the tank floor.
4 .3 Electrical connection of the filter flushing valve:
Before opening the equipment pull the plug out from the mains socket!
The connection of the valve for cleaning the rainwater filter is optional. If running
the system without the rainwater filter please read on from point 3 (Putting into op-
eration).
Before connecting the Rainwater usage system, please ensure there is no over
straining or tension on any of the connections.
The plug of the system control unit must not be connected to the socket of the
electrical supply.
Pass the end of the cable from the solenoid valve for the rainwater cleaning filter
through the threaded grommet holder provided with the housing of the SILENTIO
system control. Now open the lower housing cover
[7] of the system control (see
Figure 1). The openings for the threaded grommet holders are pre-stamped to ease
breaking out. Break out the opening for the threaded grommet holder with an
appropriate tool such as a small screw driver. Fit the supplied threaded grommet
holder into the opening and secure with the locking nut from the inside. Isolate the
wire cores of the cable in the proper manner. Pass the cable through the grommet
opening in the system control unit housing. Connect the protective earthing
conductor (green - yellow wire core) to a free terminal with the designation
“PE /
Ground” .
Connect the neutral wire core (blue) to a free terminal with the designation “5” .
Connect the live electrical supply wire core (brown or black) to a free terminal with
