Limit position switch
!
Note!
The position of the input resp. the output may be different from the figure. Please, refer to the marks
at the limit position switch: "1" is the input (in), "2" is the output (out).
Connection of the compressed air and pneumatic limit position switches
!
Note!
Following, you find the connection of the compressed air lines to the assembly. The compressed air
supply and the tapping of the position feedback signals are described for Topcal S CPC310 resp.
Topclean S CPC30 as an example.

The pneumatic limit position switches serve as control elements and determine the sequence of the
individual steps.
1.
Connect the compressed air supply line for "Assembly measuring" (Topcal/Topclean: hose
no.
n
) to the upper G 1/8 pneumatics connection (Fig. 11).
2.
Also, connect the compressed air supply line no.
n
to the inlet (1) of the lower limit position
switch (M2, via T-piece). This limit position switch supplies the position feedback signal
"Assembly measuring".
3.
When the "Measuring" position is reached, the air applied to the inlet M2 (1) is switched
through and can be tapped at the outlet M2 (2) (Topcal/ Topclean: connect hose
q
to the limit
position switch outlet).
Pneumatic:
3/2 way valve
Electric:
inductive (NAMUR type)
