The threshold values are defined as follows:
Threshold value “switch off suction” (air-saving function)
1
The vacuum generator is switched off simultaneously with the setting of the output Out A. The preset
value is -700 mbar.
Threshold value “switch on suction”
2
The threshold value
2
should always be above the switching point of channel B
3
“vacuum sensing”.
The space between
2
and
3
should be at least 50 mbar.

Requirements for product use
Warning
Manipulation of signal statuses may cause serious personal injury, depending on the
functioning of the machine/system.
Note that if the switching characteristics of the switching outputs are modified in
the EDIT mode, the new status will be effective immediately.
Activate the password protection (security code) in order to prevent unintentional
modification by unauthorised third parties (
è
Chapter 6.3 “Edit mode”).
Note
The vacuum is measured as relative pressure. The displayed pressure value is the actual
pressure difference from ambient pressure. The attainable, displayed pressure value
may be lower than the value indicated in the technical data, depending on the current
absolute ambient pressure/air pressure.
Compare the limit values in these operating instructions with those of your application
(e.g. operating media, pressures, forces, torques, temperatures, loads, speeds, operating
voltages, flow rates).
Take into consideration the ambient conditions at the location of use.
All applicable national and international regulations must be complied with.
Remove all transport packing, such as protective wax, foils (polyamide), caps (polyethylene), card
board boxes (except for the sealing elements of the pneumatic connections).
The material used in the packaging has been specifically chosen for its recyclability (exception: oil
paper = residual waste).
Use the product in its original state. Unauthorised modification is not permitted.
