5 Mounting and start-up
Risk of malfunction due to incorrectly per-
formed start-up.
Perform start-up following the described se-
quence.
1. Mount the actuator onto the valve.
Î Seesection5.1.
2. Connect supply voltage.
Î Seesection5.3.
3. Initializetheactuator.
Î Seesection8.4.
5.1 Mounting the actuator onto
the valve
The actuator is mounted either directly onto
the valve or using a yoke depending on the
valveversionused(Fig.7).
5.1.1 Type5824:force-
locking attachment
1. Turn the handwheel (2) counterclockwise
to retract the actuator stem.
2. Place the actuator on the valve connec-
tion and tighten coupling nut (4) (tighten-
ingtorque20Nm).
5.1.2 Type5824:form-t
attachment
1. Place the actuator on the yoke and tight-
en coupling nut (4) (tightening torque
20Nm).
2. Place actuator with yoke (15) on the
valve and tighten the nut (17) (min. tight-
eningtorque150Nm).
3. Pull plug stem until it reaches the actua-
torstemorextendactuatorstemusing
the handwheel (2).
4. Position the clamps of the stem connector
(16)includedintheaccessoriesonthe
ends of the actuator stem and plug stem
and screw tight.
5.1.3 Type5825:force-
locking attachment
Fail-safe action "actuator stem extends"
The actuator stem must be retracted before
the actuator can be mounted onto the valve.
The stem can be retracted either mechanical-
lyorelectrically.Bothmethodsaredescribed
below.
Retracting the actuator stem mechanically
1. Unscrewfrontcoverandplacea4mm
Allen key on the red actuating shaft.
2. Retracttheactuatorstem:turnAllenkey
counterclockwise only and only as far as
the end position where the torque-depen-
dentlimitswitchisactivated(seeFig.8).
