12. Setting the limit switching
12.1 Setting end position CLOSED (black section)
.
Turn handwheel clockwise until valve is closed.
.
Turn handwheel back by approximately half a turn (overrun). During test run check
overrun and, if necessary, correct setting of the limit switching.
.
Press down and turn setting spindle A (figure P-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 trip-
ping point inadvertently (ratchet is heard after the pointer has rotated), continue turn-
ing 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.
.
Turn handwheel back by approximately ½ a turn (overrun). During test run check
overrun and, if necessary, correct setting of the limit switching.
.
Press down and turn setting spindle D (figure P-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
rotated), 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 P-1) are used for manual operation of the limit
switches.
.
Turning T in direction of the arrow LSC (WSR) triggers limit switch CLOSED.
The green indication light on the local controls is illuminated as long as the test button
is pushed down.
.
Turning P in direction of the arrow LSO (WÖL) triggers limit switch OPEN.
The yellow indication light (fault) on the local controls is illuminated.
.
The red indication light on the local controls is illuminated as long as the test button is
pushed down.
