7.3 Configuring the outputs
Each channel provides a tension output (±10V) and a current output (0...20mA resp. 4...20mA)
which are active simultaneously. The signal of the current output is configured as follows:
Current output 0...20mA
The jumpers will be set to „0...20mA“ (fig.
8).
Current output 4...20mA
The jumpers will be set to „4...20mA“ (fig.
9).
7.4 Configuring the lowpass filter
Each channel provides an independently configurable lowpass filter. It is used to eliminate
faulty signal variations which may be caused by unbalanced rollers, vibrations of the machine,
or equivalent.
The lowpass filter is effective to both the tension- and the current output. The lower the cut-off
frequency, the more sluggish the output signal will be. The configuration is made by soldering
of a non-polarized capacitor to the soldering points (refer to fig. 5). The capacitor will be
determined referring to the following formula resp. list:
Cut-off frequency [Hz] Capacitor [
µ
F]
1 10
C = 10 / F 2 5
5 2
10 1
C: Capacity [
µ
F]
20 0.5
F: Cut-off frequency [Hz] 50 0.2
100 0.1
200 0.05
500 0.02
1000 0.01
Note
You must not use electrolytic capacitors because positive and negative signals are appearing!
They would damage the electrolytic capacitor.
