Conductivity measuring device GENO-Multi-LF 3.2 Operating person- Only persons who have read and understood this operation manual are permitted to work with the measuring device. The safety instructions in particular are to be strictly adhered to. 3.3 Intended use The measuring device may only be used for the purpose outlined in the product description (chapter C).
Conductivity measuring device GENO-Multi-LF 4 | Shipping and storage Caution! The measuring device can be damaged by frost or high temperatures. In order to avoid damage of this kind: Protect from frost during transportation and storage! Do not install or store the measuring device next to objects which ra- diate a lot of heat.
2 | Intended use The conductivity measuring device GENO-Multi-LF is used to measure the conductivity of fully demineralised water. A digital display enables di- rect reading of the fully demineralised water quality. If the set upper limit value is exceeded, warning devices (e.g.
Conductivity measuring device GENO-Multi-LF 3 | Functional description 3.1 Conductivity meas- The electrical conductivity is a measure of the ion concentration of a urement measured solution as a total parameter. The more salts or ions are dis- solved in the water, the greater its conductivity. The conductivity there- fore provides a statement on the salt load or the purity level of water.
Conductivity measuring device GENO-Multi-LF 5 | Intended use The conductivity measuring device GENO-Multi-LF is used in combina- tion with mixed bed cartridges desaliQ:BA to monitor the conductivity of fully demineralised water at the pure water outlet. The conductivity measuring device is only permitted to be operated when all components have been properly installed.

Conductivity measuring device GENO-Multi-LF Solenoid valve 707 055 The solenoid valve is only provided as an option for GENO-Multi-LF The solenoid valve (closed in de-energised state) interrupts the pure water line when the set conductivity limit value has been ex- ceeded.
Use a masonry drill (6 mm) to drill the four holes approximately 40 mm deep into the wall. Insert dowels and open the two side housing covers (see Fig. D-1) on the GENO-Multi-LF. The four enclosed fas- tening screws can be used to screw the conductivity measuring device to the wall.

Conductivity measuring device GENO-Multi-LF Note: When wall mounting the conductivity measuring device, the re- quired location of the mixed bed cartridge desaliQ:BA should be taken into account. The maximum permitted distance between the conduc- tivity measuring device and mixed bed cartridge desaliQ:BA is 1.6 m due to the cable length.
Conductivity measuring device GENO-Multi-LF 4 | Electrical connection Caution! Before opening the housing, unplug the cord transformer! After opening the left and right covers (Fig. D-1), the four lid fixing screws can be opened and the housing lid (Fig. D-4) folded downwards.

Conductivity measuring device GENO-Multi-LF Display of parameters In standard mode: • Switches to the limit value programming level (press for > 2 sec.). • Acknowledges malfunctions. On the limit value programming level: • Opens a limit value to change it (numeric display flashing).
(order no. 707 055) opens. On the basic display, the measured actual conductivity value is displayed in µS/cm. If the set limit value is exceeded, the GENO-Multi-LF issues a visual warning via an alarm LED. The solenoid valve is deenergised and there- fore closes the water feed.
Conductivity measuring device GENO-Multi-LF 4 | Deviating configuration, recalibration: (Code 290) For configurations deviating from the standard (cell constant, tempera- ture sensor), as well as a recalibration of the conductivity measurement, please contact Grünbeck's technical service/authorised service company (www.gruenbeck.com). The parameters described below are only permitted to be modified by authorised experts as incorrect values can result in property damage or malfunctions.
