3C END WASH
ENABLED
By pressing the arrow keys
éê
you can select in the
submenu "3C FLUSH TIME END" the reaction of the
control system when the set point is reached at the end
of a module flush.
SWITCHED ON: At the end of module rinsing before
the transition to the standby state, the permeate
conductivity exceeds the limit value. The alarm message
"ALARM CONDUCTIVITY" appears on the display and the
alarm output relay picks up.
The unit stops.
OFF: The conductivity control during and after module
rinsing is deactivated.

3D DELAY
0M 00Sec
Enter a delay time by pressing the
éê
arrow keys. The
delay is intended to prevent the system from being
switched off abruptly due to temporary measurement
value peaks.
0 Sec = no delay
(Causes an immediate switch-off when the set max.
conductivity value is reached. See note at the end of the
chapter)

The program jumps back to the main menu.
If a module flush is followed by a longer standstill
period, an increased conductivity value may temporarily
occur. If the parameter 3C is set to ON, this will lead to
an unintended shutdown of the system
11.6.5 RAW/MIX set point calibration
With the assistance of the feed water conductivity
measurement and a freely adjustable limit value for the
conductivity, the unit can be stopped and an alarm
message issued if the feed water quality is reduced.
