Tube Full Sensors, 1 Through 8 (Lead-In Sensors)
_______________________________________________________
This diagnostic tests port B3, located on PCB #5000-A89, PAL A69-6. Please refer to drawings #5000-
D66 and #6000-517 for sensor wiring details.
TO ENTER THIS CHECK:
Handler displays DIAGNOSTICS
Press the [1] key.
Handler displays SENSOR CHECK
Press the [3] key.
Handler displays FULL _ _ _ _ _ _ _ _ if all output tubes/lead in sensors are clear of devices. If numbers
are displayed, they indicate:
1 = Tube 1 Full Sensor
2 = Tube 2 Full Sensor
3 = Tube 3 Full Sensor
4 = Tube 4 Full Sensor
5 = Tube 5 Full Sensor
6 = Tube 6 Full Sensor
7 = Tube 7 Full Sensor
8 = Tube 8 Full Sensor
Pressing the [Clear] button will flash the terminal's displayed message to confirm the handler is still in this
specific diagnostic check.
Press the [Enter] button to EXIT this diagnostic check.
If you suspect that you have a bad sensor/LED pair, use the E XATRON LED checker part #3000-052 (small
blue plastic box.) This diagnostic tool is equipped with a transistor (blue/white wires) and an IR LED
(orange/green wires.)
Direct the transistor at any of the handler's IR LEDs. The LED on the checker should turn OFF. Direct the
checker's LED at any of the handler's transistors. The corresponding number should turn OFF on the
handler's display.
