10.Using a voltmeter, measure the voltage at the con-
tacts
E
:
• The voltage must be 23 V +/- 0.3 V.
- In the case of voltage deviations, reset the volta-
ge on the transformer in accordance with the spe-
cified values in the table.
• If there is no operating voltage:
- Check the proper positioning of the cables:
- Check the cables for breaks:
