Potential-Free Error Message; Integrating The Water Softener Into A Central Building Control System - Conel CLEAR Serie Montage- Und Betriebsanleitung

This message might also come up if the brining procedure cannot be carried out
properly during regeneration e.g. if the wastewater hose has been installed too
high, if there is insufficient line pressure or if the suction hose has not been con-
nected properly to the salt container.
If salt is only filled up after the salt storage is completely used up, the brine level might increase temporar-
ily. In this case, the suction procedure may take longer.
If the regeneration salt is used up or is not topped up in time, the water softener switches to economy op-
eration.
In this case, the brine that is still available is primarily used for disinfecting the ion exchanger resin and the
softening action is reduced.
This way, the water softener stays in a thoroughly hygienic condition even for weeks after the regenera-
tion salt was indicated as being insufficient.

POTENTIAL-FREE ERROR MESSAGE

In the following cases a collective error message can be transferred through the potential-free relay:
/ if there is an error message of the water softener
/ in case of power failure
/ in case of insufficient salt
Please make sure that the mains plug is removed from the socket for any electrical
installation work!
Please observe maximum switching current and maximum switching voltage (see
chapter 4.5 "ELECTRICAL DEVICES/EQUIPMENT")!
In fig. 19, the contacts of the potential-free relay are shown without a current (open).
For the switching function of the potential-free fault indication relay, see fig. 19!
The failure signal cable is not contained in the scope of delivery (see chapter 10.6
"ACCESSORIES").

INTEGRATING THE WATER SOFTENER
INTO A CENTRAL BUILDING CONTROL SYSTEM
Via the potential-free relay, the water softener can be integrated into a central building control system (e.g.
EIB, LCN or LON).
Example: The potential-free relay is connected to a binary bus coupler. This way, an error message can be
transmitted to the central building control system.
