OCU
16 .2 .1 Manual mode
In Manual mode, the control unit works with capac-
ity control (FCU..F1/F2 or BCU..F1/F2) regardless of
the status of its inputs. The inputs for start-up signal
(terminal 1), controlled air flow (terminal 2) and remote
reset (terminal 3) are ignored. The function of the con-
troller enable/emergency stop input (terminal 46) is
retained.
The positions for maximum capacity, minimum capacity
and ignition capacity of an actuator can be adjusted us-
ing the OCU. The OCU supports the process by means
of a cyclic, automatic repeat approach to the selected
position. The actuator can be moved within the menu to
make changes to the cam settings.
After start-up has been completed, the navigation keys
can be used, for example, to open or close a valve in
program step
