Operation
The sensor is operated via the push buttons Pos . and
Teach . To do so, press the buttons with a blunt object. See
Figure 47.
Programming
After mounting, adjust the unit to the valve positions to be
detected (see programming guides). First, clarify your type
of valve. The sensor differentiates between two types:
1. Valves with 2 operating positions (closed and open)
2. Valves with 3 operating positions (closed, open, and
an intermediate position for either seat lifting or 3-
position actuators.
For valves with 2 operating positions, the wear of the
valve seals is monitored automatically. This function is
not possible for detecting three operating positions.
The programming options are shown in the programming
overview (Figure 48). After passing into the programming
mode (Teach mode) the unit first expects the adjustment of
the closed position; however, you can also start with any
other position.
If, for example, the valve is already in the open position,
start adjusting this position. To do so, press the Pos. button
twice, thus skipping the adjustment of the closed position
and the seat position. You can carry out the skipped
adjustment steps afterwards.
Skipping a current programming step is also required if
you use valves with only 2 operating positions for which
the position seat lift is not available. If the position seat lift
is not adjusted ("taught"), the unit automatically passes
into an operating mode which monitors the wear of the
valve seals (see Set-up/operation section).
