3.2.3.3 Explanation of PerPur Display
Two additional functions of the PerPur need to be explained.
The salt consumption optimisation mechanism controlled by a micro processor sees to it
that the water softener is regenerated when a certain customer dependent operating time
has passed. The 5 pole plug 1 (see illustration below) establishes a permanent connection
between the water softener and the pure water system (see section 3.2.2).
The system has a remote fault indicator which is triggered by all malfunctions. If there is a
malfunction, this can be passed via the 2 pole plug 2 to an optical and/or acoustic transmit-
ter. This signal can also be sent to a building services management system.
The remote fault indicator is implemented by a voltage free closer.

Explanation of the LED Displays:
LED Inlet pressure: The water inlet to the Clear Water System is monitored continuously. If
the water supply is disrupted, the pressure switch notices that, the sys-
tem shuts itself down and the red LED lights up.
