2.5 Pneumatic connections
IMPORTANT
1 The actuator/valve combination can move after connecting
the air supply.
2 Ensure that the QC54 control modules are mounted
properly to the actuator to achieve good functioning and
the required ingress protection, before connecting the air
supply.
3 Check that the maximum supply pressure
Pmax = 8bar/116Psi
4 Be sure that the minimum required supply pressure for the
application is available at the actuator.
5 Take appropriate measures to prevent condensation or
moisture to entering the actuator or the control module.
Condensation or moisture can damage these components
and can result in failures.
6 The exhaust ports Ra and Rb on the module (see figure
3.1) are shipped from the factory with transport protection.
7 If ingress protection IP66 or NEMA4X is required, appropri-
ate connections must be used in exhaust ports Ra & Rb.
2.5.1 Operating media :
* Air or inert gasses.
* Air filtered at 50 micron.
* Dew point 10 K below operating temperature.
* For subzero applications take appropriate mea-
sures.
2.5.2 Single acting (spring return) or
Double acting actuator :
1 Remove the transport sticker from the air supply
(Ps).
2 Connect air supply to port (Ps).
