8.2.3 Functional level
The functional level is used primarily for testing and diagnostic purposes. Analog
and binary values of the outputs can be controlled manually here. This may be
useful, for instance, for checking an individual piece of equipment in a plant.
When performing maintenance and repair work, counters for operating hours,
switching actions and flow rates can be reset.
Functional level menu items:
• Flow: Display the current flow rate, display and reset the total quantity count-
er
• Washtimer: Manually start the wash process, display the time remaining un-
til the wash process and the current binary value
• Analog outputs: Read and manually control the current values of analog
outputs
• Digital outputs: Read current binary values, manually control digital output
outputs
• Counters: Reset the counters (operating hours and service counters)
WARNING!
When manually controlling equipment in a system, it is absolutely essential to
take appropriate measures to prevent personal injury and property damage.
Ensure that only qualified personnel has access to the functional level. The fac-
tory settings restrict access to just "Master" and "Service" users.
NOTE!
Manual control of analog and binary outputs is possible only if the "Enable
menu. mode" option is activated for the specific output in the configuration. In
general, actions at the function level can be executed only by the "Master" and
"Service" users.
