8.4.5.1 Display for Biocide Control
An active Biocide metering process is shown in text in the first line of the display.
Fig. 8.25
If the pre-circulation is interrupted the pre-circulation time is reset.
Because of lack of space the text PRE-CIRCULATION is shown as scrolling text.
Desired early bleeding before a biocide metering process is carried out if the current
conducting capacity at the time of the desired biocide metering is above the lower bleeding
limit (with negative regulation direction).
Fig. 8.26
The potential free contact that is responsible for controlling the Biocide pump is activated to
metering the biocide. It remains activated until the metering time is reached. The bleeding
regulator is deactivated during this time.
Fig. 8.27
During the tracking of the biocide the potential free contact that is responsible for
controlling the Biocide pump is deactivatedThe bleeding regulator is deactivated during this
time.
Fig. 8.28
When the tracking time is over the display returns to the normal operation display.
If there is no release condition during a forced pre-bleeding / metering process for Biocide
the relevant processes are interrupted. Once the release has returned the interrupted
process continues. The tracking process is independent of the release condition.

If PRE-CIRCULATION is set the remaining precirculation
time is displayed here.
The current conducting capacity and the status ‚bleeding'
are shown in the display.Because of lack of space the
textis shown as scrolling text.
The display shows the metering process as „METERING"
and the remaining metering time.Because of lack of space
the textis shown as scrolling text.
The display shows the tracking process as „TRACKING"
and the remaining tracking time. Because of lack of space
the text TRACKINGis shown as scrolling text.
