6 Set up the sensor with the display and adjustment module

VEGADIF 85 • Profibus PA

53569-EN-230814

The display and adjustment module has a backlight for the display.

In this menu item you can switch on the lighting. You can find the

required operating voltage in chapter "

Technical data

In delivery status, the lighting is switched on.

6.5.3 Diagnostics

In this menu item, the device status is displayed.

In case of error, e.g. the error code F017, e.g. the error description "

Adjustment span too small

" and a four digit figure are displayed for

service purposes. You can find the error codes with description, rea

son as well as rectification in chapter "

Asset Management

The respective min. and max. measured values for the differential

pressure and static pressure are stored in the sensor. In menu item "

Peak indicator, pressure

", both values are displayed.

In another window you can carry out a reset of the peak values

separately.

The respective min. and max. measured values of the measuring cell

and the electronics temperature are stored in the sensor. In menu

item "

Peak indicator, temperature

", both values are displayed.

In another window you can carry out a reset of the two peak values

separately.

In this menu item you can simulate measured values. This allows the

signal path to be tested, e.g. through downstream indicating instru

ments or the input card of the control system.
