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.
