Commissioning (see Leaflet "Operation -- a concise overview")

Because of the numerous applications it can have, the positioner must be adapted to the actuator after assembly
(initialized). This initialization can be undertaken in three different ways:
Automatic initialization
•
The initialization is automatic. The positioner determines sequentially the direction of action, the travel or the
rotational angle, the travel times of the actuator and adapts the control parameters to the dynamic behavior
of the actuator.
Manual initialization
•
The travel or the rotational angle of the actuator can be set manually; the remaining parameters are automati-
cally determined as for automatic initialization. This function is required for soft end stops.
Copying initialization data (replacing the positioner)
•
The initialization data of a positioner can be read out and transmitted to another positioner. Therefore it is
possible to exchange a defective device without interrupting the running process by an initialization.
Before initialization, you only have to set a few parameters for the positioner. The remaining parameters are set
with default values that you do not normally have to alter. If you observe the following points, you will not have
any problem with commissioning.

Preparation for linear actuators

1. Mount the positioner with the appropriate mounting kit (see Chapter 3.2, page 39).
NOTICE
The position of the transmission ratio selector in the positioner is especially important (7, Leaflet
"Operation -- a concise overview"):
Stroke
5 to 20 mm
25 to 35 mm
40 to 130 mm
2. Push the driver pin (4, Figure 1, (page 41) 2) on the lever (6, Figure 1, 2) to the scale position corresponding
to the nominal stroke or the next highest scale position and screw the driver pin tight with the nut (18, Figure
1, 2).
3. Connect the actuator and positioner with the pneumatic cables and supply pneumatic power to the positioner
(see Chapter 6, page 47).
4. Connect the positioner with the fieldbus according to Figures 5 to 7, page 65.
5. The positioner is now in "P manual" mode. On the upper line of the display, the current potentiometer voltage
(P) is displayed as a percentage, e.g. "P37.5", and on the lower line "NOINI" is blinking:
