VOLTAGE DIVIDER SETTINGS

The secondary voltage divider is set in the factory at a value

of 1:50.

Inside the machine there is a dip-switch (SW1) that can be used

to set 4 other secondary voltage values:

1:20 1:21 1:30 1:40

To access the dip-switch (SW1) proceed as follows (Fig. O):

1) Disconnect the power supply from the system by turning

the line switch on the back panel to the O position. Discon-

nect the machine’s power supply cable from the main pow-

er supply socket in the wall.

2) Remove the machine’s metal bottom plate to access the

machine’s secondary board.

3) Set the dip-switch (SW1) to one of the configurations avail-

able.

4) Reassemble the machine, following the points above in re-

verse order.
