6.4.2
Automatic reverse (only when the machine is set for intermittent
working)
Fit the jumper J3 (as well as J1).
This is used to provide an automatic reverse at the end of a working time to free the blades from any
material which may remain trapped in excessive quantity in the lower part of the chamber.
6.4.3
Reverse test
Fit the jumper J2 or short-circuit the pins with a screwdriver: the machine will reverse its revolving
direction.
This is used to check the P.C. board operation.
6.4.4
Automatic machine starting and stopping by remote operation
(Only if the shredder is connected to other machines).
Operating on terminal 6 of the P.C. board, through a clean contact which closes to ground terminal 3
or 4, it is possible to start or stop the machine.
This control is used when the machine is connected and operates in line with other machines that must
give their permissive signal.
There are two possible solutions:
1.
Terminal 6 becomes operative only after the operator has started the machine through selector
switch. J4-J5 closed – J6 opened. From this moment on, the machine works when terminal 6 is
closed with terminal 3 or 4 and stops when it is opened. Fit jumpers J4 and J5 and leave jumper J6
open.
2.
Terminal 6 is continuously operating and the machine can be started even without the operator's
intervention. In this case, the installer must take the necessary precautions to avoid whatever
hazardous situation.
•
Fit jumper J6 and leave J4 and J5 open.
•
From this moment on, the machine works when terminal 6 is closed with terminal 3 or 4 and
stops when it is opened.
