12. Setting the limit switching
12.1 Setting end position CLOSED (black section)
.
Turn handwheel clockwise until valve is closed.
.
To prevent that the end stop is reached (due to overrun) before the limit
switch has tripped, turn handwheel 4 turns (overrun) in counterclockwise
direction. During test run check overrun and, if necessary, correct setting
of the limit switching.
.
Press down and turn setting spindle A (figure K-1) with a flat blade screw
driver in direction of arrow, thereby observe pointer B.
While a ratchet is felt and heard, the pointer B moves 90° every time.
When pointer B is 90° from mark C, continue turning slowly.
When pointer B has reached the mark C, stop turning and release setting
spindle. If you override the tripping point inadvertently (ratchet is heard
after the pointer has snapped), continue turning the setting spindle in the
same direction and repeat setting process.
12.2 Setting end position OPEN (white section)
.
Turn handwheel counterclockwise until valve is open.
.
To prevent that the end stop is reached (due to overrun) before the limit
switch has tripped, turn handwheel 4 turns (overrun) in clockwise direction.
During test run check overrun and, if necessary, correct setting of the limit
switching.
.
Press down and turn setting spindle D (figure K-1) with a flat blade screw
driver in direction of arrow, thereby observe pointer E.
While a ratchet is felt and heard, the pointer E moves 90° every time.
When pointer E is 90° from mark F, continue turning slowly.
When pointer E has reached the mark F, stop turning and release setting
spindle. If you override the tripping point inadvertently (ratchet is heard
after the pointer has snapped), continue turning the setting spindle in the
same direction and repeat setting process.
12.3 Checking the limit switches The red test buttons T and P (figure K-1) are used for manual operation of
the limit switches.
.
Turning T in direction of the arrow LSC (WSR) triggers limit switch
CLOSED.
.
Turning P in direction of the arrow LSO (WÖL) triggers limit switch OPEN.
