Settings for switching points (SP), hysteresis (Hy) and buffer (FR)
Note
The switching point is derived from the Teach pressure and the buffer. A buffer
(35% of the Teach pressure) is deducted from the Teach pressure (SP = TP
0.35*TP). For example, with a Teach pressure of 0.5bar, a switching point of
0.33bar is set.
The hysteresis has a fixed value.

Requirements for product use
Note
Improper handling can result in malfunctions.
· Make sure that the following specifications are always observed.
· Compare the maximum values specified in these operating instructions with
your actual application (e.g. operating media, pressures, forces, torques, tem
peratures, masses, speeds, operating voltages, flow rates).
· Take into consideration the ambient conditions at the location of use.
· Please comply with national and local safety laws and regulations.
· Remove all transport packing such as protective wax, plastic wrap (polyamide),
caps (polyethylene), cardboard boxes (except for the covers on the pneumatic
ports).
The packing is intended for recycling (except for: oiled paper = general waste).
· Use the product in its original state. Unauthorised modification is not permitted.

Installation
The product can be fitted in any position. Mount the vacuum generator and con
nect its tubing in such a way that no condensation from the compressed air lines
can gather in the device.

· Connect appropriate tubing to the QS push−in connectors (−QS, −QO, −PL, −PO).
We recommend that tubing of type PUN−6 be used.
· When selecting the tubing for tubing connection on a vacuum generator with
threaded ports (−GN, −GO), be mindful of the minimum internal diameter for
tubing stated in Fig.12.
