Troubleshooting the BIN SENSORS
Figure 4–1
Checking the BIN SENSORS
[1] Using the PORTABLE COMPUTER, go to the
specific test mode, “Sorter Sensor Test”. The
status of the BIN SENSORS will be displayed.
With no film in the SENSOR area, “No Film
Detected” should be displayed.
[2] Place a piece of film in the SENSOR area. “Film
Detected” should be displayed.
Note
• A malfunction may be caused by a malfunctioning
SENSOR, 100 BOARD, 500 BOARD, or loose or
faulty CONNECTORS. See the Circuit Diagrams
in Section 6 for the CONNECTOR numbers
involved.
• If a BIN SENSOR is disconnected, the “Sorter
Sensor Test” on the PORTABLE COMPUTER
will indicate “Film Detected” for that SENSOR.
If a malfunction occurs, proceed as follows:
[3] Interchange the BIN SENSOR with a known
good SENSOR to see if the BIN SENSOR is
causing the malfunction. For example, assume
that BIN SENSOR No. 3 is malfunctioning:
(a) De-energize the PROCESSOR.
(b) Disconnect CONNECTOR P/J115 for BIN
SENSOR No. 3 from the 100 BOARD.
(c) Disconnect the adjacent CONNECTOR
P/J116 (for BIN SENSOR No. 4) from the
100 BOARD, and connect it to P115 on the
100 BOARD. Energize the PROCESSOR.
BIN SENSOR No. 3 should indicate “No
Film Detected” on the PORTABLE
COMPUTER.
(d) Place a piece of film in the SENSOR area for
BIN No. 4. BIN SENSOR No. 3 should
indicate “Film Detected” on the
PORTABLE COMPUTER.
(e) If the interchanged BIN SENSOR works
correctly, replace the malfunctioning BIN
SENSOR disconnected in Step (b).
Note
The BIN SENSOR in the extreme right MODULE is not used. Therefore, you may swap this MODULE with any
other MAIN MODULE to temporarily repair a SORTER that has a malfunctioning SENSOR.
[4] Check the SENSOR Enable Signal. Check for a pulsed 5 V signal (ON for 80
µ
seconds, OFF for
100 mseconds) at P/J508 PIN 14 on the 500 BOARD.
