Operating and installation instructions
Thrust actuator ARI-PACO
®
2G 1,6D/Y
- Insert mains connection plug in jack strip (pos. 50.43.3) provided for the purpose.
- Carefully place hood onto gearbox and mount firmly on thrust actuator with collar nut.
5.4.2.1.2 Setting
Installing the thrust actuator on a straight through valve, the travel switch S3 needs to be set
as follows:
- Move valve out of the lowest position so as to run valve-lift to up position.
- Using a screw driver, proceed to turn setting spindle for switch S3 (pos. 50.51) until the trip cam
(pos. 50.54) arriving from below trips the switch (audible click).
- Run thrust actuator briefly in extending direction and then in retracting direction once more,
checking to see whether the thrust actuator is switched off at the desired point (nominal lift).
- If need be, correct the setting as described.
Installing the thrust actuator on a three-way valve, the travel switch S3 needs to be set as
follows:
- Run valve in both final positions and check in each final position whether the valve switches off via
the load-dependent switch.
- Carry out a check in the top final position the see whether, after switching off the thrust actuator,
the trip cam (pos. 50.54) of the travel switch S3 is situated below switch S3 and has not tripped the
latter. If the trip cam (pos. 50.54) is situated above the travel switch S3 or trips the same, the
setting spindle governing the travel switch S3 (pos. 50.51) needs to be turned until the trip cam is
situated below travel switch S3 without tripping it.
- Run the thrust actuator in both final positions once more and check whether thrust actuator
switches off in both final positions via the load-dependent switches.
- If need be, correct the setting as described above.
