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.
10.1 Setting the direction CLOSE (black section)
.
Move valve to desired intermediate position.
.
Press down
and turn setting spindle G (figure K-2) with a flat blade
screw driver in direction of arrow, thereby observe 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
tripping point inadvertently (ratchet is heard after the pointer has rotated),
continue turning the setting spindle in the same direction and repeat setting
process.
10.2 Setting the direction OPEN (white section)
.
Move valve to desired intermediate position.
.
Press down
and turn setting spindle K (figure K-2) with a flat blade
screw driver in direction of arrow, thereby observe 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
tripping point inadvertently (ratchet is heard after the pointer has rotated),
continue turning the setting spindle in the same direction and repeat setting
process.
10.3 Checking the DUO switches
The red test buttons T and P (Figure K-2) are used for manual operation of 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.
