Mounting and start-up
Retracting the actuator stem electrically
1. Unscrew front cover.
2. Perform electrical wiring according to
Fig. 6 on page 26 and carefully refas-
ten the front cover.
3. Retract actuator stem:
Switch on power supply and retract the
actuator stem electrically until it reaches
the end position (voltage applied to eL
and N or using controller).
Risk of damage to the actuator due to incor-
rect connection of the voltage.
Do not apply a voltage to eL and aL at the
same time.
4. Fasten valve and actuator together using
the coupling nut (tightening torque
20 Nm).
Fail-safe action "actuator stem retracts"
Î
Place the actuator on the valve connec-
tion and tighten coupling nut (tightening
torque 20 Nm).
5.1.4 Type 5825: form-fit
attachment
Î
For fail-safe action “actuator stem re-
tracts” and “actuator stem extends”,
mount actuator as described in sec-
tion 5.1.2.
NOTICE
!
5.2 Installing the control valve
into the pipeline
Î
Install the valve into the pipeline accord-
ing to the mounting and operating in-
structions 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. 5).
The IP 54 rating can only be achieved up
to device index .03 when the actuator is
installed in the upright position. See the
last two figures of the configuration ID on
the nameplate (see p. 11) for the index.
