1.17 Important notes on safety
Special Safety Instr ction
Please, read and follow safety instr ctions caref lly before assembly or sing
the device!
During installation and when working with 230 V ~ mains supply the VDE
regulations must e followed. Equipment using a 230 V ~ supply may only e
installed and commissioned y a qualified tradesman. The assem ly place must
allow all possi le safety precautions when laying the attached ca les.
Page 7
Power supply ca les and data ca les may not e damaged or squeezed for any
reasons. Plan the assem ly place so that you can reach the mains plug easily and
unplug it from the electrical outlet in dangerous situations.
Choose the assem ly place so that children cannot play or e near to the device and
at its connections without supervision.
Before opening the device disconnect it from the mains supply (unplug) otherwise
there is a serious danger of an electrical shock.
Fuses may only e replaced with standard-compliant parts with the same nominal
value.
All lia ility is excluded for damages which result from non-compliance of these
instructions or from an improper handling of the device. At chosen intervals in this
hand ook we will give directions for safety precautions. These safety precautions
have een specially marked.
2. Description and intended se
The “SILENTIO” is an electronic water management control system. It has een
developed especially for rain water usage systems. It can e used with a wide
variety of tank systems. Tanks made from metal or steel reinforced cement may
only e used when the following conditions have een correctly followed.
Metal tanks lead to faulty readings. Helpful is to assem le the device so that the
sensor is as far as possi le from the metal sides so for example, in the centre of a
cylindrical tank. The system controls offer an easy to use guide for the switch
programming.
Using an LCD display the fill measurement is shown in 1 % stages (in relation to
the height of the tank).The sensor operates with a 12 volt supply. All programmed
values such as the tank height are retained after disconnection of the power supply
or after a power-cut.
3. Description
Performance features:
– Fill level measurement readout in 1% steps and with
an additional ar type indicator
– In 1% steps freely varia le choice of the switching
points for the drinking water refill
– Automatic flushing of the system (choice of intervals
in day and time are possi le)
– Dialogue oriented user guidance (choice of language)
– Equipment indication using 3 additional LED
– Supervision of the measurement pick-up and the
sensor
– Error indications in plain text

mains supply via the mains fuse.
The yellow LED indicating Drinking water operation” is lit as soon as the
valve switches over to the mains supply. The user is made aware that the
system now uses water from the mains supply. The red LED for Faults
and malfunctions” is lit as soon as the system identifies a fault. The display will
then show a warning that describes the cause of the fault in plain text.
4 . Assembly:
4.1 Control system
The electric mains supply plug acts also as the ON/OFF switch.
Before opening the eq ipment p ll the pl g o t from the mains
socket!
The system control is integrated as standard in the asic „SILENTIO“ device from
the company Graf. Caution: Always remove the plug from the mains socket efore
opening the lower cover [7] of the system control housing!

4 .2 Connection sensors and data cable:
The sensor electronics comprise of a stainless steel pro e [22] with a red and a
white connecting ca le [27] and the sensor measurement pick-up [28].
Figure 3: Sensor technology
1. Now the sensor measurement pick-up [28] (cover removed) should e
installed on the tank wall (prefera ly in the man hole shaft of the Graf
synthetic tank). The location of the mounted sensor pick-up should e
etween 10 and 15 cm a ove the overflow [25]. The enclosed screws
should e used to secure the device. After fully tightening the screws, the
points that are showing themselves on the outside of the tank must e
lunted to avoid injury [24].
2. Measure the height from the ottom of the tank [23] to the end of the
terminals [15] and [16] on the measurement pick-up [28].
3. Shorten the connection ca le to suit the measured height.
4. Connect the sensor ca le to the sensor as descri ed in the following
instructions: Remove etween 5-7 mm of the insulation from oth of the
ca les. Next, pass the red ca le through the screw mounting 1 [19] and
tighten this lightly, then connect the red ca le to the terminal [16]. The
free white ca le is now passed through the screw mounting 2 [18] and
tightened lightly, then connect the white ca le to the terminal [15].
5. Now pass the end of the data ca le that has no plug connector [12]
through the screw mounting 3 [13]. Lightly tighten the screw mounting
and connect the ca le wire cores of the data ca le [12] to the dou le
terminal [14]. The connection of the data ca le is reverse polarity
protected. Attention! The screws sho ld be tightened with care to
ens re that they are not damaged thro gh over tightening.
6. Now recheck that all the screwed items and the sensor components have
