Repair instructions
In the event of a function error, check the following:
•Check that the fuse on the back side of the machine beside the power connections strip is whole.
•Check that the voltage supplies to the electronic circuit card are OK. Measure the voltage supply on board connector X83 between the following inputs:
-X83:1 - 3 approx. 7 V~
-X83:4 - 5 approx. 15 V~
-X83:6 - 7 approx. 13 V~
•Check the three glass pipe fuses on the circuit board (see illustration on the preceding page). Fuse rating 1 A/250 V.
If the above points are checked and the function error remains, replace the entire circuit board.
