1. Assemble the positioner with the appropriate mounting kit (see
chapter 3.3.3, page 39).
NOTE
Particularly important is the position of the transmission ratio selector
(7, figure 2-1, page 24) in the positioner:
Stroke Lever
5 to 20 mm short
25 to 35 mm short
40 to 130 mm long
2. Push the carrier pin (4, figure 3-7 (page 48) 2) onto the lever (6,
figure 3-7, 2) to the scale position corresponding to the rated
stroke or next highest position and screw the carrier pin tight with
the nut (18, figure 3-7, 2).
3. Connect the actuator and the positioner with the pneumatic lines
and supply pneumatic power to the positioner (figure 2-3 and 2-4,
page 26 ).
4. Connect the positioner to the PROFIBUS line (figure 3-16, page 59
and figure 3-17, page 59).
5. The positioner is now in the operating mode "P-manual opera-
tion" The current potentiometer voltage (P) is displayed in percent
in the top line of the display, e.g.: "P12.3", and "NOINI" flashes in
the bottom line:
6. Check the free running of the mechanics in the whole actuating
range by moving the actuator with the keys
to the respective end position.
NOTE
You can move the actuator quickly by pressing the other direction key
additionally whilst keeping the direction key selected first pressed.
7. Now move the actuator to the horizontal position of the lever. A
value between P48.0 and P52.0 should be visible in the display. If
this is not the case, adjust the slip clutch (8, figure 2-9, page 33)
until "P50.0" is displayed with a horizontal lever. The more
accurately you hit this value, the more exactly the positioner can
determine the path.
