Part B MFC 085 Signal Converter
4. Operation of the Signal converter
4.1 Operating and check elements
The operating elements are accessible after removing the cover of the electronics section using
the special wrench. The converter is also programmable with magnetic sensors and a bar
magnet without removing the covers of the electronic housing.
Caution: Do not damage the screw thread and the gasket, never allow dirt to accumulate,
and make sure they are well greased at all times.
The operator control concept consists of three levels (horizontal). See next page.
Setting level: This level is divided into three main menus:
Fct. 1.0 OPERATION: This menu contains only the most
important parameters and functions of Menu 3 (install) to allow
rapid changes to be made during the measurement mode.
Fct. 2.0 TEST: Test menu for checking the signal converter
(displays, outputs, measuring range).
Fct. 3.0 INSTALL: All flow measurement- and flowmeter-specific
parameters and functions can be set in this menu.
Parameter check level: Fct. 4.0 PARAM.ERROR: This level is not selectable.
After exiting from the ”Setting level”, the signal converter checks
new data for plausibility. If an error is detected, the signal
converter indicates PARAM.ERROR in Fct. 4.0. In this menu, all
functions can be scanned and those changed that are not
”plausible”.
Reset/acknowledge This menu has two tasks and is selected via Entry Code 2
level (Quit): (
