There are two options for the operating mode.
4.4.1 AUTO
During the auto mode, the controller controls the valve
position according to the incoming setpoint signal from
the 4–20 mA signal source. This mode is used during the
normal process control service.
4.4.2 MAN
During this mode the valve position may be controlled
manually by using the keyboard and pressing the
+ or
- buttons. The position of the manually driven valve is not
saved in the memory of the controller, i.e. the valve will not
return to the same position after signal failure. However,
the valve may be driven back into position after signal fail-
ure by using
+ and - keys.The manual control starts
from the current position of the valve after the MAN-mode
is activated. In order to change the manual setpoint return
to the measurement monitoring view and go to setpoint
measurement. Press the
? key shortly to activate the set-
point editing, text SETP starts to blink and now you are
able to edit the setpoint by pressing + or - button. The
setpoint changes in 0.1 % increments/decrements in spite
of the selected unit and the valve starts to move immedi-
ately. A continuous push changes the setpoint faster. In
order to view other measurements, press the
? or =
keys and select a measurement. Repeat the previous
steps if you would like to alter the setpoint value again.
