9.14 Access to the electrical parts in the base
Access must be made when it is necessary to:
- replace the supply transformer.
- replace the zero board for the Y axis or its wiring.
- replace the commutation board for 1st/2nd speed for the cutting tool motor or its wiring.
- replace the cutting tool motor speed regulation board, change the setting or replace the wiring.
- replace the zero sensor for the Y axis.
- replace wiring.
To gain access to the base:
1) switch off the machine and disconnect the supply wire.
2) turn the machine onto its back.
3) loosen the six screws and remove the bottom plate (V3) (fig. 48).
WARNING: If it is necessary to operate in this area with the machine on (e.g. to regulate a sensor or
the 1st cutting tool rotation speed), take great care not to touch the parts of the ‘cutting
tool motor speed regulation board’ as these are connected electrically to the supply phase
(220 or 110 Volts).
