8 Mounting/Installation
8.1 Mounting of the actual-position feedback unit on the valve actuators of the SISTO-C LAP type series:
2. Screw the actual-position
feedback unit into the tread
and hand-tight.
1. Remove the guide bush on
the pneumatic valve actuator.
3. To adjust the connections exactly,
the actual-position feedback unit can
be rotated further in clockwise direc-
tion.
After adjusting the actual-position feed-
back unit can be tightened with the help
of a wire pin (Section 8.3, Page 13).
DANGER
Risk of serious injury or death due to explosion!
The actual-position feedback unit must not be operated in potentially explosive atmospheres.
ATTENTION
It is not allowed to enter following fluids in the air supply ports of the actual-position feedback unit:
- no liquids fluids
- no fluids containing solids
- no aggressive fluids
- no combustible fluids.
ATTENTION
▪ Protect actual-position feedback unit against source of radiation (e.g. the sun).
▪ Protect actual-position feedback unit against vibrations.
NOTE
▪ If the actual-position feedback unit is to be used in a damp environment, steps must be taken to ensure that any liquid that
collects drains away from and does not penetrate the housing.
▪ The housing of the actual-position feedback unit must not be subjected to mechanical loads. Connection and pneumatic
lines must be routed in such a way that no forces act on the actual-position feedback unit
NOTE
Regularly check that the electrical and pneumatic connections are correctly seated and that the connection to the pneumatic
valve actuator is correct.
