Valve Mounting For Cut-Off By Force At Extended Actuator Stem; Valve Mounting For Cut-Off By Force At Retracted Actuator Stem; Removing / Closing The Cover - PS Automation PSF-M-EX Kurz- Betriebsanleitung

4.1 Valve mounting for cut-off by force at extended actuator stem

Initial position: Valve stem is retracted, actuator stem is extended.
1. Put actuator onto the bracket.
2. Remove the coupling pin and screw the coupling 13 mm on the valve stem. There must be a 1 mm gap between
the pillars and the bracket.
3. Insert the spring clamp with the coupling pin again and fix the locking nut.
4. Connect the actuator to electric supply (see 9.).
5. Retract the actuator spindle manually (see 10.6) until the edges of the pillars rest on the bracket.
6. Screw and tighten the pillar nuts.

4.2 Valve mounting for cut-off by force at retracted actuator stem

Initial position: Valve stem is extended, actuator stem is retracted.
1. Remove the spring clamp with the coupling pin and screw the coupling 13 mm on the valve stem.
2. Put actuator onto the bracket, make sure actuator stem is immersed into the coupling. Screw on and fix the pillar
nuts.
3. Connect the actuator to electric supply (see chapter 9.), either electrically or with the handwheel and drive the
actuator manually (see chapter 10.6) until the spring clam with the coupling pin is ready to be re-inserted.

Before the pillar nuts are tightened, make sure that the
pillars are sitting on the valve mounting bracket. If
necessary, correct the position of the actuator by using
manual operation. If these instructions are not observed,
personal injury or damage to the actuator and/or valve
RIGHT
may result.
Open:
Loosen the screws by using a screwdriver and unscrew them entirely
out of the gear casing. The screws are protected against loss.
Remove the cover carefully so as not to damage the seal.
Close:
Put the cover on the gear casing and press down slightly. Tighten the
screws gently and then crosswise. It must be ensured that all screws
are tightened firmly to guarantee protection against ingress of water
and dust in accordance with EN 60529 to IP65. The tightening torque
for the Ex e/t cover is 3 Nm.
