Function 0.00.01 through 0.00.02 View error messages list/Reset error messages
All occurred error messages are stored in an error messages list and can be viewed using Function
0.00.01 VIEW ERR. The messages are kept in this list until the cause of the errors has been
removed and the error messages have been reset using Function 0.00.02 RST ERR. Errors that
have been reset, but whose cause has not been removed, are kept in the list but are displayed
without bar. This allows identification of previously acknowledged and unacknowledged errors.
Function 0.00.03 Reset Totalizer
Reset display Totalizer(s). Only available when Function 3.07.08 RST ENABLE is YES. Note that
all Totalizer values are reset.
Main menu 1.00.00 Operation
The functions in this menu are a subset of Main menu 3.00.00 Installation, and are selected in this
menu as most commonly used functions for a quick installation. Note that parameters set in these
functions are automatically set in both menus.
Main menu 2.00.00 Test functions
This menu is for testing the display, the in- and outputs and for information on hard- and software
numbers. See chapter 7.1 on functional checks.
