Collecting vessel (fill-volume min. 1 l)
1.
Determine the net weight of the collecting vessel
2.
Open the metering line at a suitable point
3.
Hold the collecting vessel beneath the opening in the metering line
4.
Start the calibration by pressing the
[START]
key.
5.
Wait until the calibration time has elapsed
6.
Weigh the captured amount of liquid concentrate
7.
Enter the determined weigh as the
[ENTER WEIGHT]
parameter in
the control
ð
The capacity is recalculated and displayed as the parameter
[CAPACITY]
in
[kg/h]
8.
Close the metering line so that it is again leak-tight
10.2.3 Calibration Flow monitor ("Spectra" only)
Before the first switching on of the system in automatic
mode, you must calibrate the liquid concentrate pump and
then the flow monitor.
The system must be switched off during calibration. Unit
[Stop].
If you operate the system for longer than 20 seconds
beneath the switching point for the minimum metering quan‐
tity, then the following message appears on the display
[Fault: Check liquid concentrate flow sensor] and the system
switches to [FAULT] mode.
