LED DS3 will blink green occasionally to confirm communication with the control
computer.
For details on background adjustment, see Section 2.6.
2.20 MONITOR CONTROL PCB (See Figure 2-25)
The Monitor Control PCB monitors the power supplies, lamp ballasts, ejector
circuits, feeder status, remote run status, air pressure switch, position of the front
viewer (DOOR OPEN), and hopper level sensors. The status of these signals is
displayed on the STATUS SCREEN. LED’s on the Monitor Control PCB also provide
their status.
During the power-up sequence, the control circuitry turns on the lamps, ejectors,
and feeders. If an item is not turned on, its corresponding LED will not be
illuminated. As power is supplied to each item, its corresponding LED will
illuminate green if it is normal. If an item has a fault, its corresponding LED will
illuminate red.
The LED for LOW PRESSURE will not normally be illuminated. If the air pressure is
low, the LED will illuminate red. The feeders will stop, and the FEEDER LED's will
not be illuminated.
The DOOR OPEN LED will not normally be illuminated. If the front half of the viewer
is pivoted open, the LED will illuminate red. The feeders will stop and the FEEDER
LED's will not be illuminated, and the wiper will not operate either automatically or
manually.
If an ejector has a fault, the EJECTOR LED corresponding to that ejector illuminates
red, and the feeder for that particular channel will stop.
The feeders are numbered as follows:
No. 1 FEEDER for channels 1 - 30
No. 2 FEEDER for channels 31 - 60
No. 3 FEEDER for channels 61 - 80
LED DS19 will blink green occasionally to confirm communication with the control
computer.
2.21 CPU INTERFACE MODULE (See Figure 2-26)
The control computer, memory modules and interface connections are located on
this PCB assembly. The connectors are shown in Figure 2-26. Connector J1 is used
when connecting a standard PC keyboard to the system.
The Battery Backed RAM is located on this module. The battery life is normally
several years, but it eventually may have to be replaced. If it is necessary to change
the battery, the history files in the RAM must be copied to a USB device before the
battery is removed, and copied back to the RAM after the battery is replaced. Check
with your service representative or call the factory for specific instructions.
NOTE: If the flash disk is removed, refer to Figure 3.1 for orientation of flash
disk when reinstalling.
