13. Setting the DUO limit switching (option)
Any application can be switched on or off via the two intermediate position switches.
For setting, the switching point (intermediate position) must be
approached from the same direction as later during
electrical operation.
13.1 Setting direction CLOSE (black section) .
Move valve to desired intermediate position.
.
Press down and turn setting spindle G (figure P-2) with a flat blade screw driver
in direction of arrow, while observing pointer H.
While a ratchet is felt and heard, the pointer H moves 90° every time.
When pointer H is 90° from mark C, continue turning slowly. When pointer H 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.
13.2 Setting direction OPEN (white section) .
Move valve to desired intermediate position.
.
Press down and turn setting spindle K (figure P-2) with a flat blade screw driver
in direction of arrow, while observing pointer L.
While a ratchet is felt and heard, the pointer L moves 90° every time.
When pointer L is 90° from mark F, continue turning slowly. When pointer L has
reached the mark F, 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.
13.3 Checking the DUO limit switches
The red test buttons T and P (figure P-2) are used for manual operation of the
DUO limit switches.
.
Turning T in direction of the arrow TSC (DSR) triggers DUO limit switch CLOSED.
The torque switch CLOSED is actuated at the same time.
.
Turning P in direction of the arrow TSO (DÖL) triggers DUO limit switch OPEN.
The torque switch OPEN is actuated at the same time.
.
After checking the switches, the fault (red indication light) has to be reset using the
OPEN or CLOSE push buttons of the local controls for operation in the opposite direc-
tion.
