● The positioner is mounted.
● You know whether the transmission ratio is to be set to 33° or 90°.
● The positioner has been commissioned successfully, i.e. initialization was completed with
"FINISH".
The following is applicable for the "flameproof enclosure" version:
• A friction clutch is provided on the outside of the positioner axis. Change the work area
using this friction clutch, legend number
⑨ in "Figure 3-9 View of positioner in
flameproof enclosure (Page 24)".
• Do not open the flameproof enclosure of the positioner in explosion-prone atmospheres.
Fix the setting acquired by initialization as follows:
1. Make sure the gear latch
① is in neutral position ③. The neutral position is between 33°
and 90°.
2. Make sure the transmission ratio selector
⑤ is in the correct position.
3. Fix the transmission ratio with the gear latch
①. Turn the gear latch ① with a standard
approx. 4 mm wide screwdriver until the gear latch
① locks. Turning right locks the
transmission ratio to 33°
②. Turning left locks the transmission ratio to 90°④. The
transmission ratio is locked.
Note
Changing the setting of the transmission ratio selector
The setting of the transmission ratio selector
⑤ can only be changed effectively if the
① is in the neutral position ③.
4. To fix the friction clutch ⑥ insert a standard approx. 4 mm wide screwdriver in the friction
clutch gear latch
⑦.
5. Use the screwdriver to turn the friction clutch gear latch
⑦ anticlockwise until it engages.
The friction clutch
⑥ is locked.
