6-4-8. DC Power Supply
The DC Power Supply receives 120 volts ac from the secondary of Power Transformer T1 when Circuit
Breaker CB1 and the Power Switch are closed. The power supply provides the following outputs to the
MCS Board, which distributes dc power to the remainder of the MCS.
•
+24 volts + 5 %
•
+12 volts + 5 %
•
-12 volts + 5 %
•
+5 volts (VCC) + 5 %
The Service Switch and interlocks on the front door, rear panel, and top hood can int12 volt and/or
+24 volt dc power to certain circuits, as shown on sheet 2 of the functional diagrams in Section 10.
6-4-9. MCS Print Sequence of Operation
The MCS is involved in six basic operations in the normal course of printing a sheet of film. These,
described in Figure 6-16, are the following:
•
Power up and self-test. (For details of the process, see Figures 7-1 through 7-7 in the
Troubleshooting section of this manual.)
•
Pick up film. (See Figure 6-17.)
•
Load the exposure platen (See Figure 6-18.)
•
Expose the film (See Figure 6-19.)
•
Unload the platen (See Figure 6-20.)
•
Process the film (See Figure 6-21.)
In addition to the basic printing operations, the folloiwng operations are flowcharted:
•
Front door close (See Figure 6-22.)
•
Front door open (See Figure 6-23.)
•
RF Tag Sequence at Cartridge Opening (See Figure 6-24.)
•
RF Tag Write and Calibration Count (See Figure 6-25.)
Note
Dotted lines between components on the flowcharts indicate that the function is a MicroComm
subsystem operation.
