Voltage Dependent Assemblies - Xerox DocuColor 12/DCCS50 Service Manual

Overview
This chapter describes the control, distribution and processing of electrical power, the safety
interlock function, and the power saving function. The machine generates a several DC volt-
ages from its AC power input. Certain machine circuits are powered regardless of whether the
main power switch is off or on. There are four types of Standby Power:
• AC power which is present when the machine's main power switch is off
Power)
• DC power which is also present when the Main Power Switch is off
Power)
• AC power which is only present when the Main Power Switch is on
• DC power which also is present only when the Main Power Switch is on
Power)
This chapter also describes Electrical Interlocks.

Voltage Dependent Assemblies

Since this machine is used worldwide, the voltage of the Prime AC Power Input can vary. Sev-
eral machine assemblies have different part numbers depending on the voltage of the Prime
AC Power input. The Prime AC Power is:
• 115 VAC at 16 amperes in the digital copier configuration and 12 amperes in the printer
(Unswitched AC configuration for Xerox Corporation (XC) markets
• 220/230/240 VAC at 10 amperes for the Xerox Europe (XE) markets
(Unswitched DC
The modules which are changed depending on the Prime AC Power Input are:
(Switched AC Powerr) • The IDFE Low Voltage Power Supply (IDFE LVPS)
(Switched DC • The Image Output Terminal Low Voltage Power Supply (IOT LVPS)
• The Image Input Terminal/Image Processing System Low Voltage Power Supply (IIT/IPS
LVPS)
• The 18 VAC Transformer
• The Fuser Solid State Relay (SSR)
• The IDFE LVPS SSR
• The Oil Pump
• The External Heat Roll Lamp
• The Pressure Roll Lamp
• The Heat Roll Lamp
