The following parameters can only be changed using the "EasyTool Controls" program:
Parameter
Setting area
Factory setting
Δp-Cycles
Number of Δp-Cycles until the
next measuring line cleaning
cycle.
Alternative to the interval.
0 – 100
0
Δp-Working range [%]
Defines the working range
below the upper threshold in
% of the measuring range.
Alternative to the lower
threshold.
1 – 100%
10%
High alarm delay [s]
Delay after exceeding the high
alarm threshold until the high
alarm relay is activated.
1 – 3600 s
0 s
Low alarm delay [s]
Delay after falling below the
low alarm" threshold until the
low alarm relay is activated.
The relay is not activated, if
the post cleaning threshold is
fallen below of during this
delay period.
1 – 3600 s
300 s
BG-Cleaning interval [h]
Monitoring time of the clean-
ing.
If there is no cleaning during
the monitoring time, a back-
ground cleaning with the par-
ametrized duration is started.
0 – 99.9 h
0 h
BG-Cleaning duration [s]
Duration of the background
cleaning.
1 – 3600 s
300 s
Password for parameter pro-
tection
Protection against unauthorized
parameter changes.
0 – 999
0
Note!
The thresholds can be set arbitrarily. There is no logical validation. If the values
of the lower threshold are parametrized as higher than the values of the upper
thresholds, then the cleaning as well as the pressure display cannot function as
expected.
