AUMA FQM, Руководство по эксплуатации

Страница: 26 / 36

6.2.1. End stop CLOSED: set
1. Operate valve in mid-position, respectively in sufficient distance from the 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. CL ; 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. CL ; or
LED is illuminated.
7. Check O-ring in screw plug and replace if damaged.
8.
Fasten and tighten screw plug next to symbol.
6.2.2. End stop OPEN: set
1. Operate valve in mid-position, respectively in sufficient distance from the end
position.
2.
Remove screw plug next to symbol.
3. Unscrew setting screw counterclockwise until reaching dimension T
min
.
4. Move valve to end position OPEN.
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 LSO end position switch signals that the
FQM has reached end position OPEN:
➥
Signal FQM end pos. OP ; 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 CLOSED. Then operate until end position in direction
OPEN.
➥ The end position OPEN is correctly set, if the end position switch
LSO
signals
that the FQM has reached end position CLOSED: Signal
FQM end pos. OP
;
or LED at local controls is illuminated.
7. Check O-ring in screw plug and replace if damaged.
8.
Fasten and tighten screw plug next to symbol.
6.3. Reference operation (adaptive end position setting)
After first initialisation and after end stop setting in the fail safe unit, each end
psoition must be approached and left during standard operation to make sure
that the actuator adopts these end positions. Imperatively perform this “refer-
ence operation” whenever an end stop resetting has been performed in the
fail safe unit.
