Spurious pulse suppression – parameter options
If measuring or exhaust air is switched on and off during operation, spurious pulses are generated
(excessive fluctuations in supply pressure). Normally, such spurious pulses must be suppressed by
programming the higher-order controller.
Spurious pulses can be suppressed in the air gap sensor SOPA by adjusting the parameters [Options].
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).
1
Spurious pulse suppression when using the instrument air on/off function with
deactivated exhaust air.
2
Spurious pulse suppression with use of the function exhaust air on/off and with
instrument air switched off.

Options for spurious pulse suppression
2.3.4
Switching off the display
The numerical (7-segment) display for the distance-correlated value can be switched off permanently or
for a defined time delay. Both switch-off modes allow the usage of the INFO mode and the SHOW mode
for a limited time.
2.3.5
Security code
The settings can be protected from unauthorised access by setting a numerical code which is up to
4digits in length. The security code must be entered each time a setting is changed (EDIT mode and
TEACH mode).
2.3.6
Min/max values
The min/max values for supply pressure monitoring and distance monitoring can be displayed and reset
in the SHOW mode

Chapter 5.5.
Note
Switching off the supply voltage resets the min/max values.
