Operating and installation instructions
Thrust actuator ARI-PREMIO
Fig. C: - Slip 2-ear clamp (pos. 50.26) onto a distance column (pos. 50.24) press on
very lightly.
- Screw distance column with 2-ear clamps on opposite side of handwheel into
the flange in such a way that one of the 2-ear clamps is situated above the
torsion safety feature (pos. 50.32) and the other below.
- Screw the other distance column into the flange likewise.
- Place thrust actuator (pos. 50) with distance columns onto valve and fix into
position with two self-locking hexagon nuts (pos. 50.25).
Fig. D/E: - Fold out turning handle of handwheel (pos. 50.12.1), slightly turn the
handwheel and press in the engaging button for manual mode (only 12 - 15 kN)
(button engages). Having done this, move out the thrust actuator until driving
spindle (pos. 50.30) comes into contact with threaded bush (pos. 50.87).
Fig. F: - Screw coupling (pos. 50.27) firmly into torsion safety feature (pos. 50.32) and
secure using grub screw M6 (pos. 50.35).
- Move the valve to the lowest position.
- Press 2-ear clamps (pos. 50.26) into position according to the stroke so they
cannot slip, with the bottom clamp in the lowest valve position located directly
below torsion safety feature (pos. 50.32) and the top clamp in the highest valve
position located directly above the torsion safety feature.
- Move the valve to both travel positions and check that it reaches them reliably.
- Fold turning handle of handwheel (pos. 50.12.1) back in.
- Make the electrical connection (see point “5.4 Electrical connection”). The
engaging button for manual mode (only 12 - 15 kN) disengages when the
motor starts up.
- Set standard travel switch S3 (see point 5.5.3.2).
