6.2.1.
End stop CLOSED: set
1.
Move valve to intermediate position or to sufficient distance from end position.
2.
Remove screw plug next to
symbol.
3.
Unscrew setting screw counterclockwise until reaching dimension T
min
.
4.
Operate the valve in end position CLOSED to ensure that valve is safely closed.
Information: In motor operation: Interrupt travel in time prior to reaching the
end stop and continue the last fraction of the travel in manual operation to
prevent damage.
5.
Turn setting screw clockwise until
LSC
end position switch signals that the
FQM has reached end position OPEN:
➥
Signal
FQM end pos. closed
; or LED
at local controls is illuminated.
6.
Check settings: Use motor operation to operate the vale with actuator a fraction
of travel back in direction OPEN. Then operate until end position in direction
CLOSE.
➥
The end position CLOSED is correctly set, if the end position switch
LSC
signals
that the FQM has reached end position CLOSED: Signal
FQM end pos. closed
; or LED
is illuminated.
7.
Check O-ring in screw plug and replace if damaged.
8.
Fasten and tighten screw plug next to
symbol.

Actuator settings (for initial commissioning)
For safe commissioning of the FQM fail safe unit, the settings for “type of seating”
and “torque switches” must be adapted to the valve within the actuator; i.e. they must
be set or checked. (The settings are described in the operation manual pertaining
to the actuator.
