Description
Control
1-1
Steam output
limitation
Steam output limitation allows scaling down the
max. (steam) output within a range of 25 to 100 %,
which may be necessary for a better control perfor-
mance. The actual steam output is determined by
the control signal.
1-2
Control signal
This parameter tells the unit control software what
kind of control signal is wired. Also, the control cha-
racteristic is defined. These are the setting options:
1 = external controller, 0...10 V
2 = external controller, 0...20 mA
3 = external controller, 0...140 Ω
4 = PI controller, 0...10 V
5 = PI controller, 4...20 mA
6 = PI controller, 0...140 Ω
7 = 1-step
8 = Modbus
1-3
Correction of
input stages
This parameter allows for an active humidity sensor
calibration in the range from
-5% r.h. to +5% r.h. .
1-4
Filter input
stage
This parameter allows for switching the damping of
the input low pass filter from „light“ to „strong“.
With
a capacitive humidity sensor, increasing the input
damping is meaningful for improving the signal-to-
noise ration and for reducing the oscillating ten-
dency.
Blow-down
2-1
Correction
partial blow-
down
In case of high electrical conductivity of water or
excessive maintenance effort, increasing the blow-
down frequency may be meaningful. When conduc-
tivity is low, however, a lower blow-down frequency
may be adequate. To cope with different water qual-
ities, blow-down rates may be adapted within a
range of 10 stages (factory presetting is „0“).
Increase blow-down rate: settings up to +5.
Decrease blow-down rate: settungs up to - 5.
A blow-down rate too low will lead to significant
wear and tear and will also increase the mainte-
nance effort required.
Pls. note:
a „-5“ setting will shut off blow-down
completely!
