Compresse d Air Supply Accessories (Optional)
Depending on the accessories purchased, the connections for the compressed air supply are also
located at this point. Either as a simple connection nipple or with one or two compressed air control
valves with pressure monitor etc.
Pressure monitor
For critical applications, we use pressure monitors to monitor the applied compressed air.
This is the case, for example with tool changing systems, where otherwise without compressed air
the changing process could not be carried out and then a crash could occur.
If the pressure is not reached, the software interrupts the process and issues an error message.
