▪ If the actual-position feedback unit is to be used in a damp envi-
ronment, steps must be taken to ensure that any liquid that collects
drains away from and does not penetrate the housing.
▪ The unit must never be cleaned with a water jet and/or aggressive
cleaning agents (observe the requirements of the type of enclosure
Section 7.2, Page 8/Section 7.4, Page 10).
▪ The housing of the actual-position feedback unit must not be sub-
jected to mechanical loads. Connection and pneumatic lines must be
routed in such a way that no forces act on the actual-position feed-
back unit.
▪ Protect actual-position feedback unit against source of radiation
(e.g. the sun).
▪ Protect actual-position feedback unit against vibrations.
▪ Regularly check that the electrical and pneumatic connections
are correctly seated and that the connection to the pneumatic valve
actuator is correct.
▪ Never exceed the permissible application and operating limits speci-
