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 8, page 25) 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 26 (page 55) 2) onto the lever (6,
figure 26, 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 26, 2).
3.
Connect the actuator and the positioner with the pneumatic lines
and supply pneumatic power to the positioner (figure 10 and 11,
page 27 ).
4.
Connect the positioner to the PROFIBUS line (figure 35, page 66
and figure 36, page 66).
5.
The positioner is now in the operating mode "P--manual
operation" 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 friction clutch (8, figure 16, 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.
