Press INIT key to start initialization!
The initialization procedure may
take several minutes, depending on
the actuator size, as the valve moves
through its entire travel/angle of ro-
tation range.

SUb
(substitute configuration, without initializa-
tion)
This initialization mode is an emergency
mode. The positioner parameters are esti-
mated and not determined by an initializa-
tion procedure, so that a high stationary ac-
curacy cannot be expected.
You should always select a different initial-
ization mode if the plant allows it.
The initialization mode SUb is used to re-
place a positioner while the process is in op-
eration. For this purpose, the control valve is
usually fixed mechanically in a certain posi-
tion, or pneumatically by means of a pres-
sure signal which is routed to the actuator
externally. The blocking position ensures
that the plant continues to operate with this
valve position.
The spare positioner should not be initial-
ized. If necessary, reset the spare positioner
using Code 36 .
After the old positioner has been replaced
with a new one, the following parameters
must be entered: pin position (Code 4 ),
nominal range (Code 5 ), direction of action
(Code 7 ) and closing direction (Code 34 ).
The default travel limit of 100 % (Code 11 )
must be disabled with OFF .
In addition, the blocking position (Code 35 )
must be adjusted with the
it matches the position of the previously
blocked valve.
The parameters K

and the pressure limit (Code 16 ) should re-
main set to their default values. If the config-
uration data of the new positioner are
