Hold behavior Selection
• Freeze last value
• Fixed value
• Ignore
Factory setting
Ignore
Freeze last value
The device freezes the last measured value.
Fixed value
You define a fixed measured value that is output
at the output.
Ignore
A hold has no effect.
1) %0V is variable text which you can assign in Menu/Setup/Additional functions/Cleaning/Chemoclean
Plus/Output label 1 ... 4.
Formula
Function = Controller
Function Options Info
Operating mode Selection
• PWM
• PFM
Factory setting
PWM
PWM=pulse width modulation
PFM=pulse frequency modulation→ 90
Source of data Selection
• List of available
formulas
• Maximum of 8 formulas
Mathematical functions of type Formula must be
available.
‣
Select the formula which is to serve as a data
source.
Range lower value 0 to 9999
Range upper value Range lower value to
9999
Cycle duration
Operating mode = PWM
Shortest turn-on time to
999.0 s
Factory setting
10.0 s
‣
Specify the cycle duration within which the
duty cycle should be varied (only PWM).
The settings for Cycle duration and Shortest turn-on time affect one another. The following applies:
Cycle duration ≥ Shortest turn-on time.
Shortest turn-on time
Operating mode = PWM
0.3 s to Cycle duration
Factory setting
0.3 s
Pulses that are shorter than this limit value are
not output in order to conserve the actuator.
