4.2.5 External control input
The connector sets may be operated with an external command value entry
(extraneous control input). The following extraneous command values can
be used for setting the working stroke:
•
0...10 V DC, resistance approx. 40 kOhm
•
4...20 mA DC, working resistance 100 Ohm
•
0...20 mA DC, working resistance 100 Ohm
NOTE
NOTE: If necessary, you can switch between external control inputs by
means of a switch or relay or between command value presetting? by
means of a vibration-width adjuster (potentiometer).
NOTE
NOTE: To prevent switching faults, use only gold-plated or hermetically
sealed contacts.
Figure 4.7 shows the various options and binding post assignments for
presetting extraneous command values.
ATTENTION! Connection set damage! The illustrated extraneous command
values and their respective binding post assignments are not compatible
with one another!
NOTE
NOTE: Use onty potentiometers (limit values between 1 and 10 kObm) with
linear characteristics for the vibration-width adjuster Shield the signal
lines to guarantee the electromagnetic compatibility if the lines exceed
five metres in length!
ATTENTION!
