13.7 EPROMs
The software for the control unit is held on two EPROMs.
The LPKF
ProtoMat C30 (C30/S)
must be partially dismantled if the
EPROMs need to be replaced.
Proceed as described under "Removing the electronics unit".
Use only an PLCC pliers to remove the EPROMs as otherwise the
mounting contacts might be damaged.
Support the board from below when inserting new EPROMs to avoid
bending the board. Take care that the orientation of the EPROMs is
correct.
13.8 Switching the device voltage,
electrical fuses
Danger! Make sure that the mains connector is removed before
working on the fuses or opening the device.
The primary and secondary voltages on the LPKF ProtoMat C30 (C30/S)
are fused. The mains (primary) fuses are in the control unit power
connection and can be accessed from the outside.
Caution! Make sure that
both
fuses are replaced when switching to
another line voltage. Both fuses must have the
same
rating.
fig. 37: Setting the voltage and
fuses
The secondary fuses are inside the control unit.
The control unit must be removed from the mechanism before replacing
the fuses. Proceed as described under "Removing the electronics unit".
