ITX BOARD REPLACEMENT.
ITX POWER SUPPLY.
LARGE POWER SUPPLY.
The ITX mother board supplies the graphics to the touch screen display, to remove.-
1. Switch the mains power off.
2. Cut cable ties and unplug all the plugs.
3. Unscrew the four fixing screws attaching the board to the plate and remove from the
machine.
Note. the RAM should stay with the board.
Refitting is a reverse procedure to the above.
If using the existing USB stick the machine calibration will be as before but using a new
stick will lose the settings and will mean recalibrating the machine.
This supplies power to the main control PCB and the graphic interface ITX control board and is
located as above.
5 volts DC is used as the control circuit and 12volts DC is utilised for the Safety circuit.
Switch the mains power off.
Remove the four posi pan head screws securing the flanges and withdraw slowly.
Unplug all plugs from the PSU flying leads and remove the Mains connector.
Replacement is the reverse procedure.
There are two Small Stepper Driver Boards; which supply the drive motors with the correct
power.
These are located behind the Operator Side door.
Switch the mains power off and disconnect from the mains supply.
Cut any cable ties and unplug the green plugs and spade connectors.
Unscrew the fixings attaching the PCB to the panel.
Refitting is the reverse of above but care should be taken to ensure that the rotary switch and
the dip switches are correctly set for the correct PCB, see Wiring Diagram.
Attach spade terminals in the correct positions and refit.
These supply power to the machine and are located inside the OperatorSide Door. (see
section on covers for removal).
Switch the mains power off.
Remove all screws from the support flanges and slide out the power supply.
