entry, touch ENTER ACTION. The Keypad Window (Figure 2-4) will appear. Enter the

text (up to 30 characters) and touch OK to save the information. The date and time

of the entry will be logged automatically. The system stores the most recent 100

entries. To review the list of entries, use the scroll bar on the right screen.

To save the maintenance log to a USB device, place the USB device in the USB

connector located on the card cage inside the electronics cabinet. Touch the SAVE

TO DISK button. To save the fault log to a USB device, place the USB device in the

USB connector located on the card cage inside the electronics cabinet. Touch the

SAVE TO DISK button.

The number of Ejector Cycles by each valve is recorded. When a valve is replaced,

the count of that valve can be reset to zero. Select the number of the valve to be

reset using the scroll bar on the table, then touch the RESET EJECTOR CYCLES

button.

The operating hours for the lamps in the ScanMasterII are logged. When the lamps

are changed, the lamp hour display can be reset to zero by touching the RESET LAMP

HRS button.

2.12 PRINTED CIRCUIT CARD CAGE (See Figures 2-17 and 2-18)

The printed circuit card cage provides slots into which the printed circuit boards are

installed and connectors that provide power and signal connections.

The printed circuit boards must always be installed exactly as shown in Figure 2-17

for two-view machines, and Figure 2-18 for single-view machines.

Always turn the power off before removing or installing a printed circuit board.

2.13 TIMING PCB (See Figure 2-19)

2.13.1 INDICATORS

The Status LED on the front of the Timing PCB will illuminate green under normal

sorting conditions. If the Ejector Test switch (SW3) on the Ejector Interface PCB

(Figure 2-22) is ON, the LED will illuminate red.

2.13.2 TEST POINTS

Test point TP3, (Yellow) on the front edge of the Timing board allows monitoring the

Start Sync signal using an oscilloscope (used for trigger to synchronize

oscilloscope).

2.14 AMPLIFIER PCB (See Figure 2-20)

The Amplifier PCB amplifies and processes the signals from the optical sensor PCB.

There are two amplifier sections on each PCB.
