4. Mount positioner on actuator (see chapter 2 or 3).
5. Make electrical connections as shown in fig. 7.2. Connect
also the control signal of the positioner as decribed in
chapter 4.
Wiring information
Wiring dimension : 1.5 mm 2 / 14 AWG
Tool : Screwdriver 0.6 x x 3.5 mm
Turning moment : 0.8 Nm / 7 in/lb
6. Set jumpers to “Direct” or “Reverse” to achieve a 4-20 mA or
a 20-4 mA feedback (see fig. 7.3).
7. Move the actuator pneumatically to the fully closed position.
Adjust the trimmer marked “Zero” to achieve a 4 mA reading
(20 mA in case of "Revers Action").
8. Move the actuator pneumatically to the fully open position.
Adjust the trimmer marked “Span” to achieve a 20 mA
reading (4 mA in case of "Revers Action").
