The Power Unit generates the supply voltages.
Function
The Power Unit is switched on by the ON/OFF switch on the front panel. The
supply voltages of +15, – 15 and +5 volts are generated by a transformer
on the input mains supply of 115V/230V. Each of the voltage supplies has
its own fuse on the lower printed circuit board of the front module as shown
in the diagram below.
Front Module
If one of the LEDs on the front panel does not light up (F2, F3 or F4) or the
equipment does not function (F1 or F5), check the fuses. (Always follow the
ESD instructions are presented at the beginning of this handbook when
changing fuses.)
