to do so can result in damage to the device, personal injury or property damage.
6.2. Operating personnel
The device installation and operation of the device may only be carried out by trained and qua-
lified persons. They must have read and understood the operating instructions. The following
safety instructions must be strictly observed.
6.3. Safety instructions
Softcontrol Data/F is to be installed as a wall device in accordance with the in-
stallation regulations. Operation is only permitted in rooms with a relative humi-
dity of 20% to 60% and ambient temperatures of 5 °C to 50 °C. It must be en-
sured that no condensation can form in the housing.
Operation in connection with ionization or electrolysis systems is not permitted.
The device must be protected from direct exposure to moisture and unauthorized
mechanical or electrical interference.
As portable electrical equipment, the electrical protective measure of the device
must be tested repeatedly within 24 months in accordance with DIN VDE 0702,
Part 1, the test must be verified and protection class I must be restored if neces-
sary.
Softcontrol Data/F has protection class I and may only be operated with a mains
voltage of 100… 240 volts / 50… 60 Hz with permanently effective protective
earth via an easily accessible protective contact socket. The safety plug of the
device must always be used to disconnect from the mains.
Mechanical commissioning must always be carried out in a voltage-free state.
The electrical connection to external signaling devices must not exceed the per-
missible operating voltage.

8
The raw and soft water of the softening process to be monitored must basically meet
the requirements of the applicable drinking water ordinance.
A constant sample pressure of a minimum of 1 to a maximum of 10 bar of raw and
soft water must be ensured during operation. The difference between raw and soft
water pressure should be as small as possible.
The sample liquids must be free of particles, otherwise flow filters ≤ 0.1 mm must be
installed in front of the sample inputs.
Before removing the sensor from the measuring chamber, the power supply to the
device must be interrupted. Otherwise water may splash out of the measuring cham-
ber.
There is constant water pressure up to the solenoid valves. Before servicing the sol-
enoid valves or before dismantling the measuring device, the raw and soft water lines
must be shut off. Otherwise water may splash.
When decommissioning, the sensor must be removed from the measuring cell and,
as provided by the manufacturer, stored in the original packaging in a moist, tight
and dark place.
The manufacturer reserves the right to make changes in line with technical progress.

7. General overview of functions
Softcontrol Data/F takes soft water in the bypass at the outlet of a water softener, depending on
the process, determines it and evaluates the residual hardness at the specified limit value. The
measurements are carried out with a selective sensor for calcium and magnesium ions, which
is inserted pressure-proof into a flow measuring chamber.
Upstream shut-off valves regulate the extraction of minimal process water quantities and the
subsequent pressure-free drainage of the water sample. Additional reagents and consumables
are not required.
The measuring system calibrates itself through cyclical automatic switchover from soft water
to raw water.

The device is parameterized with four buttons on the control unit. Device status, measurement
functions and results are shown with a display and colored LEDs. In addition, the measured
values are available via a 4… 20 mA interface.
Softcontrol Data/F monitors the soft water quality. When the hardness limit is reached, a limit
value alarm is triggered. Sensor faults are signaled externally via a potential-free contact. All
measured values and operating data can be saved on an USB stick.
Softcontrol Data/F can be connected to a LAN via an Ethernet interface. The parameterization
and control of the device function is possible via the Ethernet interface.
Softcontrol Data/F has various measurement modes and can therefore be flexibly adapted to the
respective measurement task. The measurement modes are explained below.
In the following illustration, a water softener is monitored by means of release contact-control-
led measurement with high soft water throughputs.

8. Operating mode
8.1. Time-controlled measurement and offline function
Assuming that the measurement pause has not been set to 0 minutes in the "interval" parameter
menu, a (steady) measurement is carried out at the interval of the parameterized measurement
pause.
The measuring process begins after switching on the device by measuring the raw water hard-
ness. The soft water measurements follow until the measured value of the sensor has stabilized
(steady measurement). Further hardness measurements are carried out according to the para-
meterized measurement pause between two hardness measurements.
If the set hardness limit is exceeded, a counter measurement is carried out in the raw water to
check. If the set hardness limit is exceeded, a limit alarm is triggered. The corresponding relay
output is switched after the set alarm delay has elapsed.
If the result of one of the following hardness measurements falls below the hardness limit value,
the limit value alarm is automatically reset. The measurements are then continued continuously
until the limit value has been undershot.
The device can be switched to offline mode via a potential-free contact (offline contact). No
hardness measurements are made in this state.
8.2. Water meter or release controlled measurement and offline function
Provided that the measurement pause has been set to 0 minutes in the parameter menu "inter-
val", the soft water measurements are carried out as long as a flow is detected.
The flow is recognized and evaluated by the impulses of an externally connected contact water
meter. Alternatively, instead of a contact water meter, an external potential-free closer (release
contact) can be used for continuous measurement.
To activate this mode, set the interval to 0 minutes and connect an external potential closer to
terminals 31 and 32. With an active short-circuit on terminals 31 and 32, the water hardness is
continuously determined. This mode works in the same way as the water meter controlled mea-
surement.
This makes it possible to enable process or flow-dependent monitoring of the soft water in the
absence of a contact water meter.
The measuring sequence is similar to the measuring sequence of the time-controlled measure-
ment. The only difference is that measurements are not time-controlled, but are triggered via a
connected potential-free contact water meter (connection terminals 27 and 28). After the mea-
sured value of the sensor has stabilized in the soft water, the device waits for further water meter
pulses. A soft water measurement takes place with each pulse.
Regardless of whether a contact water meter or a release contact is connected, the offline contact
can be used to stop the measurement as long as this contact remains closed. No hardness mea-
surements are made in this state.

9. Installation
9.1. Mechanical installation
Softcontrol Data/F is to be installed in the immediate vicinity of the water softening system to
be monitored as a wall unit with a mounting surface of 500 x 500 mm (width x height). For
mounting, 2 pieces M8 screws must be installed horizontally at a distance of 360 mm, prefe-
rably at eye level, in accordance with the subsurface on the intended mounting surface. The
assembly material must be provided by the customer.
It is also important to ensure that there is an easily accessible protective contact socket with a
mains connection voltage of 100… 240 V / 50… 60 Hz approx. 1 m next to the device, as well
as a pressure-free drain with nominal diameter ≥ 5/8“(DN 15) in the immediate vicinity below
the device.
For the extraction of the raw and soft water, there must be branches with preferably ¼“internal
threads at the inlet and outlet of the water softener.
It must be ensured that a water pressure of at least 1 bar to a maximum of 10 bar is constantly
applied during operation.
After selecting the mounting surface and installing the mounting screws, the device must be
hung up and screwed tight.

9.2. Hydraulic installation
The hydraulic installation includes the assembly of the sample connection lines and the drainage
hose and finally the sensor:
1. Tighten the installation of the drainage hose (screw connection 1) and guide the drainage
hose into the existing drain on site
2. Screw the supplied ¼" screw-in connection into the shut-off branch of the raw water and
tightly plug the sample hose (OD 4 mm) into the screw-in connection on both sides and
into the straight plug connector (blue hose Ø 4 mm OD) pre-assembled outside the hous-
ing. To mount the prefilter, the sample hose must be disconnected at an accessible point.
3. Screw the supplied ¼" screw-in connection into the shut-off branch of the soft water and
tightly plug the sample hose (OD 4 mm) into the screw-in connection on both sides and
into the straight plug connector (black hose Ø 4 mm OD) pre-assembled outside the hous-
ing. To mount the prefilter, the sample hose must be disconnected at an accessible point.
4. Open the upstream raw and soft water branch valves and check all connectors for leaks.
The water pressure is now up to the normally closed valves raw water (RW)
and soft water (SW).
The mechanical and hydraulic installation is completed with a positive leak test.
Note:
Upstream fine filters can be omitted if the existing filter systems can exclude contamination
from dirt particles in the sampling valves!

10. Commissioning
10.1. Requirements for commissioning
Before inserting the power plug into the socket outlet, the following safety instructions must be
observed:
Check electrical contacting of central control valve
Check of hydraulic tightness
Commissioning can be started after a successful check.
If “no sensor” is shown in the display, there is no electrical contact between the
sensor and the controller device.
The active operation of the device is indicated by the green "Online" LED.
A short cyclical flashing of the green LED shows that the internal control functions are active
and Softcontrol Data/F is working properly.
The specified process parameters must be set again or confirmed.
10.2. Switch on the device
After switching on the device, a quality assessment is started and completed after approx. 5
minutes. The quality assessment determines the current hardness difference between the inlet
and outlet of the water softener. As a result, a limit value violation is displayed or the soft water
quality is rated as good. The measuring program then continues to work according to the spe-
cified parameters and the result determined.

20
10.3. Control unit and display in measuring mode
Control unit
Softcontrol Data/F is parameterized via the control unit and the measurement results and ope-
rating modes are read. Parameterization and menu control are carried out using four buttons.
The measurement result and device status are shown in the illuminated display. In addition,
there are three LEDs for operating and fault signaling in the upper area:
