1.0 REPAIR INSTRUCTIONS

1.1 GENERAL CLEANING

Remove the machine shell and clean carefully

with compressed air.

1.2 MACHINE: VISUAL INSPECTION

1. Check the general conditions of the electronic

circuit ref. 1, particularly the varistor (fig. 1) if

it presents bursting marks.

• the state of the levelling condensers (fig.

2): check if there are swellings or breaks

on the container

• la presenza di crepe o rotture sulle salda-

ture dei trasformatori T1 e T4

• the presence of cracks or breaks on the

welds of the transformers T1 and T4

• check for the presence of burned tracks or

electric discharge marks on the printed cir-

cuit. In case of faults replace always the

electronic circuit ref. 1

2. Check, on all the harnesses, the insulation of

the cables and the state at the connection

points.

1.3 CHECK OF THE MAIN COMPONENTS

WITH TESTER (OHMMETER) ON THE

CIRCUIT REF. 1

1. Check for the presence of short circuits on the

rectifier bridge and the correct value of the

power resistance (fig. 3)

2. Mosfet of the primary circuit and diodes of

recycle: test points 1-2, 1-2, 2-3 of compo-

nents A and B; points 1-2 of components C

and D (fig. 4).

3. Diodes of the secondary circuit: check points

1-K of components E-F (fig. 5)

• If there are short circuits or faults during

these tests, replace the electronic circuit.

1.4 CHECK OF GENERATOR OPERATION

WITH OSCILLOSCOPE AND VOLTMETER

1. Connect a regulated power supply between

TP1 ( + 15 Vdc) and TP2 (GND), short-circuit

between TP1 and point A (fig. 6); set the

oscilloscope on a time base of 5 uS and a

range of 0.5 V/Div with probe x10 and verify:

• the presence between points: 3 (GND) - 1

(probe) (fig. 4) of the waveform shown in fig.

7: if the waveform differs from the one in the

figure or there is no wave form, the electro-

nic circuit is broken.

2. Disconnect the feeder and remove the short

circuit, set the oscilloscope with a range of

1V/Div and connect the probe X100 between

points M (GND) and P (Probe) (fig. 8); con-

nect the machine to the power supply, switch

it on:

• the motor fan starts up, and after approx. 2

seconds a wave will appear as in fig. 9.

• check with a voltmeter that the output vol-

tage is approx. 60Vdc (see test specifica-

tion point 2).

• If the wave form does not appear or the

output voltage is not correct, replace the

electronic circuit ref. 1

3. If there is not a correct current regulation

replace the circuit ref. 36; if the fault appears

again, replace the circuit ref. 1

Carry out the final test after the repair.

2.0 FINAL TEST

1. Carry out the safety test according to our ope-

rative instruction N. SLL12, before proceeding

act as follows:

• insert a insulating thickness to avoid dischar-

ges or short circuits between the electronic

boards (ref. 3) and their supporting turrets.
