6. Should the bores for the screws not align:
→
Remove screw plug and sightly unfasten setting screw [1] for end stop
OPEN/CLOSED at fail safe unit counterclockwise until bores [ ] line
up. When unfastening the setting screw, the FQM moves back in direction
of the valve flange bore [ ].
Risk of setting screw falling out!
→
Avoid excessive unscrewing of setting screws. Observe dimension T
min.
! Refer
to: Risk of damage to end stop if setting screw is turned against the spring force.
page 25, End stops in the fail safe unit
→
Do NOT unscrew setting screw clockwise against the spring force (fastening).
7. Fasten fail safe unit with screws.
Information: We recommend glueing the screws using thread sealing material
(e.g. LOCTITE 243) to avoid thread contact corrosion and to ensure vibration
resistance.
8. Fasten screws crosswise to a torque according to table.

Information
If the bores [ ] are not yet aligned for dimension T
min.
, the mounting procedure must
be aborted. The following steps have to be performed:
1. Remove fail safe unit from valve.
2. Establish electrical connection and connect to power supply.
Once the power supply is connected, initialisation is started provided all pre-
requisites are fulfilled.
➭ page 24, Initialisation
3. After initialisation, screw the setting screw to dimension T
(at 90)
(without tolerance
margin indicated). ➭ page 25, End stops in the fail safe unit
4. Then, switch off power supply again (de-energize).
The actuator performs a fail safe operation and moves to the configured fail
safe end position.
5. Now, re-place the valve onto the fail safe unit and mount to the valve as de-
scribed in the present chapter.
When mounting the fail safe unit onto the valve coupling, select splines as to
ensure that bores of the screws for the FQM and the valve flange are as close
as possible.
