Operating levels of the FMR
Operation of the FMR is done via the process operating level and via the configuration level.
The process operating level is active after
switching on the device. In this level, one can
switch between the AUTOMATIC and MANUAL
modes by briefly pressing the manual/automatic
key. In the AUTOMATIC mode, the position or
process control runs; in the MANUAL mode, the
valve may be opened or closed by hand. To
change to the configuration level, one must press
the M/A key for 5 s. In the configuration level, the basic
functions and, if needed, supplementary
functions are specified on first
commissioning. During configuration,
the process falls into a stationary state
with the parameters immediately prior to
switchover. Return to the process level
is done from the menu item END.
