AUMA SA 07.1 - SA 30.1 - Setting the Limit Switching; Setting End Position CLOSED; Setting End Position OPEN; Checking the Limit Switches

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 26) with screw driver
(5 mm) 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.
.
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 D (figure 26) with screw driver
(5 mm) 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 26) are used for manual operation of
the limit switches.
.
Turning T in direction of the arrow LSC (WSR) triggers limit switch CLOSED.
The yellow 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 green indication light on the local controls is illuminated as long as the
test button is pushed down.
