Safety instructions for pneumatic connections

WARNING
Injuries from pneumatic actuators
Due to the high operating forces of the pneumatic actuator, work done on control valves carries a risk of injuries.
Please observe the corresponding safety instructions for the pneumatic actuator in use.
Pneumatic connection
WARNING
Owing to safety reasons, the pneumatic auxiliary power supply must be fed after installation only if the positioner is
switched to the "Manual mode" when an electrical signal is available.
NOTICE
Observe the specifications regarding the air quality in accordance with section "Technical data (Page 27)".
Procedure
In the case of integrated mounting with the OPOS Interface (VDI/VDE 3847) interface, the pneumatic connections are
already connected. Mounting of the positioner is described in section "Mounting on actuator with OPOS interface (VDI/VDE
3847) (Page 11)". Connect the supply air directly at the input of the actuator intended for this purpose.
If the interface of the actuator does not correspond with the VDI/VDE 3847 directive, the positioner is mounted using the
adapter block of the corresponding mounting kit. The description is supplied with the respective mounting kit and is not part
of this operating instructions.
Note
After installing the pneumatic connections, check the tightness of the entire control valve. Besides continuous air
consumption, the positioner may try to compensate the position deviation due to leakage. This will lead to premature wear in
the entire control unit.
