Mounting and start-up
Risk of damage to the actuator by turning it
too far.
Only retract the actuator stem as far as the
nal travel value.
3. HoldAllenkeyinplaceandfastenvalve
and actuator together using the coupling
nut(tighteningtorque20Nm).Remove
Allen key and carefully refasten the front
cover.
Retracting the actuator stem electrically
1. Unscrew front cover.
2. Perform electrical wiring according to
Fig.10onpage28andcarefullyre-
fasten the housing cover.
3. Retractactuatorstem:
Switch on supply voltage and set signal
sourceto10Vor20mA.Theactuator
stem retracts until it reaches the end posi-
tion (torque-dependent limit switch
switches off the motor).
Alternatively, set the direction of action
switchinsidethedevice(seesection8.2)
toincreasing/decreasing(<>).Inthis
case,theinputsignalmustbe0Vor
0mA.
4. Fasten valve and actuator together using
the coupling nut (tightening torque
20Nm).
Fail-safe action "actuator stem retracts"
Place the actuator on the valve connection
and tighten coupling nut (tightening torque
20Nm).
5.1.4 Type5825:form-t
attachment
Î For fail-safe action “actuator stem re-
tracts”and“actuatorstemextends”,
mount actuator as described in sec-
tion5.1.2.
5.2 Installing the control valve
into the pipeline
Î Install the valve into the pipeline accord-
ingthespecicationsinthemounting
and operating instructions of the valve.
Î The control valve can be installed in the
pipelineinanydesiredposition.Howev-
er, a suspended mounting position of the
actuatorisnotpermissible(seeFig.9).
