The other signals of the analogous inputs (port 0) of D402 are given in the Overall Circuit
Diagram. At the pins of ports 1 to 4, which are not described, there apply signals the parameter of
which are changed during the program running time; in general they are pulse-shaped.
5.3. Power supply (A100)
At the A100 subassembly only the output voltages are checked in the stand by and power modes.
In case of a negative result check and, if required, replace the mains fuse element of this
subassembly. If this does not eliminate the trouble replace the subassembly.
WARNING:
There are several accessible components on mains potential!
ATTENTION:
The earthing conductor is screwed on and, thus, the contact is not
necessarily ensured!
5.4. Output circuit (A300)
With this subassembly, take particular care for correct soldered connections and tightened screw
connections, otherwise, due to the heavy RF currents partial thermal overloading can occur.
5.5. Harmonic filter (A500)
Take particular care for correct soldered connections. In case of voltage arcovers or burning
replace the subassembly by an intact, adjusted one. In any case, do not replace components of this
subassembly because this would negatively affect the adjustment which can only be performed by
the manufacturer.
