Emergency program / By-pass
The function "Emerg. Program/BP" has to be selected for the input "PROG" in the menu "Funct. PROG". In addition to
this, the contact type has to be selected . A float switch, which signals the emergency program, is connected to the input
"PROG
A
. It is placed underneath the empty level.
A solenoid valve is, e.g., connected to the output "BP" in order to open the by-pass line.
If more water than the plant can supply is required during the production, the level in the storage tank falls to a level
below the empty level. Emergency program starts as soon as the float switch for the emergency program responds, i.e.
the relay for output "BP" switches. This leads, e.g., to the opening of a solenoid valve in order to supply water of a
pre-connected softening plant. An additional pressure pump can also be switched on.
Emergency program ends when the empty level has been reached.
Conductivity monitoring
The integrated conductivity measuring instrument is used for the quality monitoring of the plant.
"OFL" appears on the display if the measuring range is exceeded.
Temperature compensation of the conductivity can either take place automatically or manually with a programmable
compensation factor. Sensors with PT100 temperature sensors (or external sensors) have to be used for the automatic
compensation. In the case of manual compensation (suitable with constant water temperature), enter the temperature.

Description of the functionality and programming of the conductivity limit values:
LV Permeate Max: Maximum conductivity value which should guarantee a sufficient water quality.
"M"
 BASIC PROGRAM  LV Permeate Max
LV Permeate Min:
Minimum conductivity value which is necessary due to the existing raw water quality. But if
conductivity does fall below this value, an error in the plant or the controller is present.
(e.g. in the case of an interruption between controller and measuring sensor = parting of a cable).
