Operating and installation instructions
Thrust actuator ARI-PACO
®
2G 1,6D/Y
5.5.3 Special functions
5.5.3.1 "Y-in"- signal failure
With analogue control, an interrupted control signal is detected by the electronics (both 2 to 10 V
and 0 to 10 V). If the control signal fails for longer than ten seconds, the red
"Failure"
LED is set
and the actuator is switched to
"Stop"
..
As soon as a control signal is detected at the input again for longer than ten seconds, the red LED
goes out and the actuator returns to the desired position.
5.5.3.2 Double control at the 3-point input
The 3-point control signal takes priority over the analogue input signal, e.g. for fail-safe or anti-
freeze protection. If a signal is present at both inputs (double control), the control mode is
interrupted.
5.5.3.3 Priorities
The actuator is controlled according to the following priorities:
5.5.4 Options
Priority
Control
High
- Reset
- Initialization (cancelled by reset)
- Manual: Stop / up / down
- Failure
- Ext. input L-down
- Ext. input L-up
Low
- Y-input
ATTENTION !
- The thrust actuator may only be operated for a short time without the hood for
unavoidable setting operations to the electronics, the relay card and the electrical
options. While these operations are in progress, the thrust actuator has hazardous,
live, uninsulated parts exposed as well as moving and rotating parts.
- Improper execution of the setting operations or lack of care may cause death,
grievous bodily injury or substantial property damage.
- Operation of the thrust actuator without the hood for any purpose other than that
described above is strictly prohibited.
