Operating and installation instructions
Thrust actuator ARI-PACO
®
2G 1,6D/Y
Actuator not moved into end
position by 0 V control signal
(control with 0 to 10 V control
signal)
There is AC voltage due to
induction voltages on the control
signal
- Don't lay the signal line directly
adjacent to main lines
- Use shielded cables for the
control signal
- Connect a 100 µF to 470 µF
capacitor parallel to the signal
input
There is AC voltage (approx. 8.5
V for a 0 V control signal) at the
signal input if a common ground
is used for the control signal and
the 24 VAC power supply (three-
wire).
This could be due to a wiring
error in the 24 VAC power supply
for the signal source (e.g.
controller)
Check the polarity of the 24 VAC
power supply for the signal
source (e.g. controller) and if
necessary reverse it
The internal resistance of the
signal source, e.g. a controller or
PLC, is too high. The measuring
voltage for detecting cable breaks
no longer collapses completely
Connect a 1000 ohm resistor
parallel to the Yin input.
Note:
The 1000 ohm resistor should be
installed immediately
downstream of the signal source
to ensure that the actuator's
cable break detection function
works correctly
