9.4 Adjusting the Position of magnetic switch
DANGER
1.G0002
Mortal danger from electric shock
Exposed power contacts - High Voltage
Every time the arm of the loader has to go to pedestal, the position of the furnace platform is
checked. It is done by means of the magnetic switch, situated on the pneumatic cylinder, which
actuates the furnace platform.
If the error 7 occurs when loader is in automatic operation (but the furnace platform is really at
the lower position) or there is an error, signalised by continuous short beeps, in single step-
operation after the horizontal Laser
check (see chapter “Single step operation”), then the
position of the magnetic switch has to be adjusted.
Adjustment procedure:
1.
Remove the panel, marked red on the lower picture to get access to magnetic switch.
2.
Toggle the loader control board to single-
step operation (see chapter “9.1 Single step
operation”).
3.
Advance to the step c) of the sequence.
4.
Ensure that the furnace is open and the furnace platform is in the lower position. Ensure
that there is nothing under the furnace platform, preventing it from going to the lower
position. If it is the case and the position of the magnetic switch is wrong, it will be
signalised by continuous beeping
5.
Loose the lock-nut (4) of the screw (5) on the clamp (3), holding the magnetic switch (2)
on the pneumatic cylinder (1); then loose the screw (5).
6.
Move magnetic switch (2) upwards or downwards, until the beeping stops, mark the
position of the magnetic switch on the cylinder at one of its edges.
7.
Continue moving the magnetic switch (2) in the same direction, until the beeping comes
again. Mark the position on the cylinder (1) at the same edge of the magnetic switch (2),
as before. Now the “active zone” on the cylinder is confined by the two markings.
8.
Place the mag
netic switch (2) in the middle of the “active zone”.
9.
Fix the magnetic switch (2), by driving the screw (5) on the clamp (3), and then fix the
lock-nut (4).
