2. Correct usage in accordance with regulations Softening Control monitors a parameterizable threshold value of residual water hardness in soft water of softening plants based on cation exchange. It provides a gradual percentage monitoring of the water hardness threshold values from 0.25% to 10% of the input water hardness. -
Page 6: Terms Of License
5. Terms of license On purchase, the user acquires an exclusive non-transferable right of use for the installed software. The use is permitted for the operation of the purchased device only. Any other use, transmission, copying or recompilation of the software is prohibited. Equal conditions apply for software updates. -
Page 7: Safety Requirements
6.3 Safety requirements The measuring device is set up as wall mounted unit and must be installed ac- cording to installation instruction. It should be operated in rooms with a relative humidity between 20 % and 60 % and an ambient temperature between 5°C and 50°C. It must be ensured that condensation can not form in the housing. -
Page 8: General Overview Of The Device
7. General overview of the device Softening Control is an online water hardness measuring system for continuous monitoring of water hardness differences between process inlet and process outlet of a connected water sof- tening system based on cation exchange. By using of bypass technology the device extracts time controlled or flow rate depending minimal amounts of raw or soft water from the process, evaluates the residual hardness and alerts with exceeding of a preset threshold value. -
Page 9: Characteristics
Once a day a sensor forming will take place in row water, which purposes of an increasement of the sensors service quality. The sensor forming will take 17 minutes. During this time no water hardness measurement will take place. The measurement system can set in off-line-mode by a connected potential free closer. In this mode no measurement will take place. -
Page 10: Installation
9. Installation 9.1 Mechanical installation Softening Control must be installed in close proximity to the softening system to be moni- tored. Installation is possible as wall or base frame mounted device with an installation space of 300 x 300 x 150 mm (wide x height x depth), preferably at eye level. For installation at the mounting area the mounting hole at the device case are to be used. -

250 OHMS 9.3.3 Connection ON / OFF signal Softening Control is staying in ON-mode as long as there is no short circuit between the ter- minals 20/21. It will stay on OFF-mode while both terminals are connected. In this state no measurement will be done. -
Page 13: External Signalling By Potential Free Contact
9.3.4 External signalling by potential free contact The external threshold value excess alarm and the brine alarm are connected to terminals 1/2- 3, and the external service alarm is connected to terminals 4/5-6. The service alarm is a summery alarm, which can be caused by: - low sensor performance - there is no electrical contact to the sensor - valves do not work properly. -

9.3.5 Connection external closer for activation of measurement Instead of a water meter an external closer can be connected at terminal 23 and 24. Measure- ments will be carried out as long as the contact is closed. In contrast to the use of the ON/OFF contact the measurements starts immediately with soft water samples. -

10. Commissioning 10.1 Setting of DIP-Switches Prior to commissioning of Softening Control the correct installation and connections to the softening system must be checked again. This includes the softener system should be operat- ing and adequate soft water quality should be available at the outlet. - Page 17 Setting of threshold value in % in reference to the raw water hardness Threshold Example: With a raw water hardness of DIP 1 DIP 2 DIP 3 value 5.0 mmol/l alarm will be signalized at: 0.25% 0.013 mmol/l 0.50% 0.025 mmol/l 1.00% 0.05 mmol/l 2.00%*...

10.3 Operating tests 10.3.1 Test of water quality By temporary interruption of power supply Softening Control re-starts the measurement and proceeds a new calibration independent of preset measuring cycle. Provided that the quality of soft water is really below the parameterized threshold value, upon completing the measure- ment result will be displayed by the luminescent green LED and the current loop comes into operation. -
Page 21: Service
11. Service 11.1 Delivery/Transport/Storage of hardness sensor Each hardness sensor is clearly identifiable by its sensor number. Prior to delivery each sensor has to pas an extensive quality check, where the sensor quality will be checked and docu- mented. The sensible part of the sensor is tightly closed with a protective cap to protect the sensor membrane against interferences and to keep it in a sterile and humid climate. -
Page 22: Operating Conditions Of The Sensor
11.2 Operating conditions of the sensor The accuracy of the sensor is influenced by Required water conditions: the quality of the water, particularly by natural raw water with a hardness deposits of iron, high concentrations of value between 0.18 mmol/l up to 10.8 heavy metals, chlorine or salt and microbi- mmol/l ological contamination. -
Page 23: Malfunction/Breakdown Of Sensor
11.4 Malfunction/Breakdown of sensor 1. Deposits on the sensor Precipitations and deposits on the sensor prevent an adequate monitoring. Examples: Rust- and iron deposits form a light red/brown coating in the flow chamber and the sensor system Up streamed filters should prevent from precipitations of iron, copper or aluminum. Biofilm growth in consequence of to high microbial count in the water Biofilms appear highly when the softener or the measuring device has been out of operation for some days or weeks and water was kept in the chamber. -
