Model PDC - 1E Volt/Hz
Modified Article AC Power Pack (Discharge)
Reason for
To facilitate SPD #430 and #431 adjustment.
Modification
The service manual describes tha t the data of SPD430 is "800" and SPD4 31 is "300 " (SP D43 0: Transfer belt
discharge voltage, SPD431: Separation corona voltage). However, th ese SPD’s were adjusted at the factory
to other parameters for stabilizing the outpu t voltag e of the powe r packs. So, to fix the parameter of these
SPD, the power packs have been modif ied .
Please refer to RTB-007 "Parameter setting for AC Powe r P ack (Discha rge )".
