Ensure that the pneumatic connections of the positioner
and those of the actuator are situated preferably vertically
one above the other (see "Fig. 9").
NOTE!
Too high torque when screwing in the fastening screw does
not ensure degree of protection IP65 / IP67.
▶ The fastening screws may be tightened to a maximum torque of
1.5 Nm only.
→
Attach the positioner to the actuator using the two side fastening
screws. In doing so, tighten the screws only hand-tight (max.
torque: 1.5 Nm).
NOTE!
Damage or malfunction due to ingress of dirt and moisture.
To observe degree of protection IP65 / IP67:
▶ In the case of actuator size ∅ 80, ∅ 100
connect the pilot air outlet which is not required to the free pilot
air port of the actuator or seal with a plug.
▶ In the case of actuator size ∅ 125
seal the pilot air outlet 2 which is not required with a plug and
2
feed the free pilot air port of the actuator via a hose into a dry
environment.
