6 . Set the output voltage for 32 V resp. 6 0 V . Close switch S; adjust load
for max. output current. Adj1ist P52 for a voltage T70e: T70c of
4 V on 32 V models
(at 220 V line)
5 V on 6 0 V models

Set the current limit to max. nominal output voltage as in 6 .
Decrease the output voltage to zero by decreasing load to zero ohms.
Note the voltage across T70 . Adjust P5 1 for a behaviour as shown above.
8 .
Set the outpu.t voltage at 2 0 resp. 30 V on 32 resp. 6 0 V models .
Vary the load from max. monimal to 0 ,
6
times max. nominal. The voltage
across T70 should not vary more than 0, 5V .
9 . S et the output voltage to 22 resp. 35 V on 32 resp. 60 V models. Set the
output current
to
max. nominal. Adjust P50 for min. (0, 5 V) influence on
the voltage across T70 by line voltage variation 200-240 V .
Reset the voltage across T 7 0 t o 4 V resp. 5 V, every time P50 is
changed.
