VEGAPULS 61 • Foundation Fieldbus
A linearisation is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. in a horizontal cylindri-
cal or spherical tank - and the indication or output of the volume is
required. Corresponding linearisation curves are preprogrammed for
these vessels. They represent the correlation between the level per-
centage and vessel volume. By activating the appropriate curve, the
volume percentage of the vessel is displayed correctly. If the volume
should not be displayed in percent but e.g. in l or kg, a scaling can be
also set in the menu item "Display".
Enter the requested parameters via the appropriate keys, save your
settings and jump to the next menu item with the [ESC] and [->] key.
Entering a 4-digit PIN protects the sensor data against unauthorized
access and unintentional modification. In this menu item, the PIN is
displayed or edited and changed. However, this menu item is only
available if adjustment is enabled in the menu "Setup".
In delivery status, the PIN is "0000".
In this menu item, the internal clock of the sensor is adjusted.
When a reset is carried out, all settings (with only a few exceptions)
are reset. The exceptions are: PIN, language, lighting, SIL and HART
mode.
The following reset functions are available:
•
Delivery status: Restoring the parameter settings at the time
of shipment from the factory. A created false signal suppression,
user-programmable linearization curve, measured value memory
as well as event memory will be deleted.
