Water level control for overflow collecting tank
The
NR-12-TRS-2 collection reservoir control system is a technically high-quality product which can only
correctly fulfil its function if it has been connected and assembled in accordance with the instructions and if this
operating manual is followed. The
overflow channels. It is constructed with integrated circuitry and consists of:
The submerged electrodes do not cause any electrolyte formation in the water because they are operated with
alternating current. The electrode cables can be extended up to 20 m (min. 1.5mm
balancing. The electronic circuitry has been specially developed for overflow collection reservoirs. Wave
movements do not cause direct switching processes due to special circuitry in order to avoid switching cycles
which may be too short.
The submerged electrodes are operated using non-hazardous safety low voltage. The controller itself has been
designed to comply with the currently applicable German VDE and CE regulations.

The controller must be installed in accordance with its protection class. Before opening the housing, the
device must be switched voltage-free using a multi-pole main switch with a contact opening distance of
at least 3 mm. This main switch must be integrated in the on-site installation. It is imperative that you
observe the throughflow direction (arrow direction) indicated on the solenoid valve.
Depending on the swimming pool design, it is possible that rainwater raises the water level in open-air pools and
activates the "forced switching" function. If this operating behaviour is not required, "forced switching ON"
(terminal 8) can be disconnected.

Operating manual NR-12-TRS-2 Page: 2 Installing the submerged electrodes: submerged electrodes are supplied as series with waterproof and ozone-proof special cables. The tensile strength of the cable is sufficient for hanging the electrodes from the special cable in the overflow collection reservoir, and it is also possible for individual electrodes to touch each other. -
Page 3: Functional Information
All other submerged electrodes are necessary for control system function and may not be omitted or bypassed. Functional information: NR-12-TRS-2 collection reservoir control system has the following functions: Water level regulation. Once the water level falls below the "solenoid valve OPEN" submerged electrode due to water losses in the swimming pool, e.g. - Page 4 Operating manual NR-12-TRS-2 Page: 4 Device setting facilities: The control system includes 4 DIP switches and 2 trimmers which can be used to set additional control system functions.
