The following parameters can only be changed with the "EasyTool Controls" program (
see
also chapter 6.4 Parameterisation with Service PC)
Parameters

Default
setting
Pre-
assignment
p
-Filter
p-Filter constant for damping the
p measurement.
0.1 … 10.0 s
2.0 s
p
-Work Area
Defines the working range
below the upper threshold in
% of the measuring range.
Alternative to the lower
threshold.
1 … 100%
10
High alarm Delay
Delay after the high alarm
threshold has been exceeded until
the high alarm relay is switched.
0.1 … 30.0 s
2.0 s
Low-alarm Delay
Delay after falling below the
low alarm threshold until the
low alarm relay is switched.
The relay is not switched if the
value falls below the final
cleaning threshold within the
delay.
1 … 600 s
300 s
Precoating Offset
The precoating offset
increases the start threshold
for cleaning (upper threshold).
At an offset of 0. the
precoating function is
disabled.
After reaching the first
cleaning threshold (increased
by the precoating), the
precoating is automatically
disabled.
OFF, 0 … 500.0

1.0 mbar
3.0 mbar
13.0 mbar
Post-cleaning Offset
The automatic post-cleaning is
activated when the value
"Post-cleaning threshold" +
value "Offset post-cleaning" is
exceeded (is independent of
the lower threshold).
0.5
– 10.0 mbar
2.0 mbar
2.0 mbar
5.0 mbar
10.0 mbar
Note!
The threshold values can be set as required. There is no logical check. If
the values of the lower thresholds are parameterised above the values of
the upper thresholds, the cleaning and pressure display cannot function
as expected.
