Switching the module on in DC
Plug the DigiMod AMP AUX cable to the CN8 connector
and feed +18 V .
DC
Plug a second DC power supply to the mains connectors
FA01 and FA02.
Feed +30V .
DC
The current drawn by the module should not exceed:
3 mA ± 5% FA01/FA02.
31 mA ± 5% from CN8.
Check the diode's bridge by repeating the test
inverting the polarities on the +30Vdc feed.
As portrayed in (Fig. 13)
Checking the Vrails voltage in DC
Power the module on in DC
Leave the module on for at least 2 minutes.
Check the positive rail bus from CH2:
+20 V ± 5% FA8 to F3
DC
Check the negative rail bus from CH1:
–20 V ± 5% FA6 to F2
DC
As portrayed on (Fig. 14)
In case this values are out of range, proceed by opening
the module as portrayed on
the test as portrayed on (Fig. 15)
