Troubleshooting
SOLUTION
PROBABLE CAUSE
PROBLEM
Rapid tooth wear
'
Material defective
.
The materials may present
altered zones either on the
surface, such as oxides or
sand, or in section, such as
under--cooled inclusions.
These zones, which are
much harder than the blade,
cause the teeth to break: dis-
card or clean these materials.
Broken blade
'
Head speed too high
.
Reduce head speed.
'
Teeth in contact with material
before starting the cut
.
Always check the position of
the blade before starting a
new job.
'
Insufficient coolant
.
Check the coolant level and
clean piping and nozzles.
'
Vibrations
.
Workpiece vibrates in the
vice: check that the slide is
regulated correctly; check the
clamping pressure and if nec-
essary increase.
Troubleshooting (control console diagnostics)
This section deals with problems which may occur during machine operation. The
MEP 24 controller allows you to test all the machine electrical and electronic
devices by checking the status of the input and output signals on the IUD/IUV
card.
Displaying the diagnostics menu
"
Power up the machine as per the instructions in Chapter 5;
"
press F6 to access machine diagnostics;
"
press RESET to enable the digital outputs.
Should access to the diagnostics menu prove impossible, then press F3 imme-
diately after powering up the machine;
The diagram below shows the inputs and outputs, both digital and analog, of the
machine:
