Teaching the switching points (TEACH mode)

The process for teaching the switching outputs OutA (A pushbutton) and OutB (B pushbutton) is basic-
ally identical. The procedure is described below based on the binary signal OutA.
1. Establish the desired switching distance between the object and the measuring nozzle.
2. Press and hold the A pushbutton.
3. Also press the Edit button.
Ä – [OutA] and [TeachIn] flash. The value is adopted as the switching point.
– [Lock] flashes: security lock active. The value is buffered.
4. Enter the set security code using the A or B pushbutton.
5. Press the Edit button.
Ä – [OutA] and [TeachIn] flash. The cached value is accepted as the switching point.
– RUN mode is active.

Setting the spurious pulse suppression (EDIT mode)

If measuring or exhaust air is switched on and off during operation, spurious pulses are generated
(excessive fluctuations in supply pressure). Spurious pulses can be suppressed in the air gap sensor
SOPA by adjusting the parameters [Options].
Requirement: EDIT mode is active.
1. Select the Special menu [Spec] with the A or B pushbutton.
Ä [SPEC] flashes.
2. Press the Edit button repeatedly until [Option] is displayed.
3. Select parameters with A or B key è Tab. 19 Options for spurious pulse suppression.
4. Press the Edit button to confirm the set value.
Ä The next adjustable parameter is shown.
Option Meaning
Off Spurious pulse suppression switched off (factory setting).
Setting optimised for short response times (spurious pulse suppression can be
implemented using a higher-order controller).
