Before carrying out any operation on the machine, make sure it is in safety condition!
The wiring diagram for connecting the VDC utilities is shown below.
After making the electrical connections, simulate a work cycle.
This simulation must be done without the guard for checking the movements of the lever mechanisms
and the signals. This operation must be performed solely by suitably trained personnel authorized for
the use and maintenance of the VDC only after having read this Manual.
Check to make sure the limit switches on the cylinders are adjusted correctly. The limit switch must
send a signal the moment the cylinder is in the maxium extended and retracted position.
Check to make sure the openings of the flaps correspond to the respective power supplies of the
coils.
Check to make sure there are no air leaks in the various connections.
Check to make sure, when the flap is open, the cylinder is completely extended and that there is a
gap of at least 5mm between the lever and the stud bolt.
