Display Info
R236
Selection of
characteristic
controller
dir = direct
inv = inverted
Setting may or may not be
required depending on control
deviation (up or down deviation,
see chap. 5.5.4).
R237
Selection of pulse
length or pulse
frequency
len = pulse length
freq = pulse frequency
curr = current output 2
Pulse length e. g. for solenoid
valve, pulse frequency e. g. for
solenoid-operated metering
pumps, see chap. 5.5.2, S. 40.
Selection of current output 2 is only
possible, if O2 = Contr is selected
R238 Enter pulse interval
10.0 s
0.5 ... 999.9 s
This field only appears if pulse
length is selected in R237. When
pulse frequency is selected,
R238 is skipped and input
continues in R239.
R239
Enter maximum
pulse frequency
of actuator
120 min
–1
60 ... 180 min
–1
This field only appears if pulse
frequency is selected in R237.
When pulse length is selected,
R239 is skipped, and input
continues in R2310.
R2310 Enter minimum
ON time t
ON
0.3 s
0.1 ... 5.0 s
This field only appears if pulse
length is selected in R237.
R2311
Enter basic load
0%
0 ... 40%
Selecting the basic load, you
choose the desired dosage
quantity.
100% basic load corresponds to:
steadily on at R237 = on
F
max
at R237 = freq
20 mA at R237 = curr
R2312
Enter process type
Batch
Inlne
Batch = discontinuous process
Inlne = continuous process
Selecting “Batch”, there is no
further dosage within the setting
range. The I component is being
decreased.
Selecting “Inline”, there is a
constant dosage within the
setting range. The I component is
effective.
Factory settings are printed in bold face;
