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 afterwards in electrical
operation.

13.1 Setting 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, 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 tripping point inadvertently (ratchet is heard after

the pointer has snapped), continue turning 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 K-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 tripping point inadvertently (ratchet is heard after

the pointer has snapped), continue turning 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 K-1) 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 (DOEL) triggers DUO limit switch OPEN.

The torque switch OPEN is actuated at the same time.
