4.1 Function of GENO-softwatch Komfort
Triggering conditions for an analysis start
Automatically via the set time interval
Manual analysis by pressing key T1
3 minutes after turning on the device
4 minutes after a limit value is exceeded with the first value
suppression activated
Switching on a connected flow controller after system standstill
By means of a connected external control unit
Note:
An analysis takes 3 minutes plus the set flushing time.
One measuring cycle comprises 5 steps
[1]
Delay time for the analysis to
start, if delay time is > 0,
adjustable delay time:
1 – 30 minutes.
Start of the interval period of
5/10/20 or 30 minutes
When monitoring hot water, the sample must be
cooled to below 40 °C (< 104 °F). A cooling water
valve can be opened via relay REL 3. Only after the
sample has reliably been cooled down after an
analysis delay time to be set, the inlet solenoid valve
will open and the analysis will start.

Flushing and cleaning of the
measuring chamber with
sample water
Adjustable flushing time:
5 seconds – 30 minutes
The inlet solenoid valve opens. The measuring
chamber and the feed line will be flushed until it can
safely be assumed that there is water from the
process to be monitored in the measuring chamber.
The flushing time can be adapted to the length of the
supply line.

Filling the measuring
chamber with sample water
for zero calibration:
Measuring without adding
any indicator
Prior to the proper measurement, a zero sample has
to be taken at all times. The zero sample is used to
determine influencing disturbance variables such as
sample turbidity, contamination of the lens or
extraneous light influences and to take them into
account for the evaluation of the water sample.
The actuator LED lights up. The solenoid valve is
open during the zero sample.
