3.3. Manual activation
Directly controlled by the PLC, the solenoid valves actuate the pneumatic cylinders.
The pneumatic cylinders can be activated manually by pressing a key (
B ). This manoeuvre may prove to
be useful during tests or maintenance.
When the key
(B) is released, the pneumatic cylinder returns to its rest position (except for pneumatic
cylinders activated by 2 solenoid valves).

3.4. Pressure control unit
To guarantee an optimal work of the bar feed system, the service
pressure must be at least 5 bars (75 Psi). The pressure control unit
serves to confirm that this pressure is present and adequate.
The pressure control unit is directly integrated into the air unit.
Setting procedure for the pressure control unit:
•
Remove the transparent panel from the pressure gauge
•
Using a screwdriver, turn the setting screw
•
Refit the transparent panel on the pressure gauge.
