This section 4 is repeated in the form of pull-out condensed operating instructions (pages 17-20).

4.2 KROHNE operator control concept
4.2.1 Description
The operator control concept for the UFC 500... signal converter consists of 3 levels (horizontal), see below.
Setting level: This level is subdivided into 3 main menus.
Fct. 1.0 OPERATION : This menu contains only the most important parameters and functions of
menu 3 to allow rapid changes to be made during the measuring mode.
Fct. 2.0 TEST: Test menu for checking the signal converter.
Fct. 3.0 INSTALL.: All flow measurement- and flowmeter-specific parameters and functions can be
set in this menu.
Parameter check Fct. 4.0 PARAM.ERROR: This level is not selectable. After exiting from the “setting level”, the
level: signal converter checks new data for plausibility (inconsistency). If an error is established, the signal
converter reverts to menu 4. In this menu, all functions can be scanned and those, that are
inconsistent, changed.
Reset/acknowledge This menu has two tasks and is selected via Entry Code 2 (
↵↑→
), see sect. 4.2.5
level: 1) Separate resetting of totalizers, provided that resetting is enabled by setting “YES” under fct.
3.6.10 ENABL.RESET.
2) Error scanning and acknowledgment (Quit)
Errors that have occurred since the last acknowledgment are indicated in a list. After
acknowledgment and elimination of the cause(s), these errors are deleted from the list.
