17. AUTOMATIC CLAMPING SYSTEM
Fig. 15
Check the following in the event of a malfunction of the PL automatic clamping system:
- Check the workshop compressed air system, which must deliver a constant pressure of at least 7 bar (100psi);
- check for and, if necessary, clear any debris in the CPL filter at the rear of the machine;
- check that the solenoid valve cable is connected correctly to the main board (R, Fig.3);
- check that the two solenoids of the solenoid valve function correctly;
- check for air leaks in the pneumatic air circuit of the PL unit.
After replacing the solenoid valve, the 0.5-12 Bar distributor (A, Fig.15) or the VBU 1/8 driven valve (B, Fig.15), reconnect the lines correctly as
shown in figures 16 and 17.
The machine can be equipped with one of the two DISTRIBUTORS shown in figure 17.
