Carrier Tape Sensor and Controller
The Carrier Tape sensor detects when carrier tape is not inserted in the Car-
rier Tape Input Guide. When the Carrier Tape sensor is triggered, a red LED
is illuminated on the Carrier Tape Sensor Controller (3 in Figure 5-78).
Problem:
• Error message "Tape Out Unit" displays and the red LED on the Carrier
Tape Sensor Controller is illuminated.
Check this:
) Replace the carrier tape reel if it is empty.
) Adjust the Carrier Tape Sensor Controller if the reel still contains car-
rier tape. See below.
Adjusting the Carrier Tape Sensor Controller
1. Set switches—
Ensure that the switches are set as shown:
MODE = D.ON
ALM = OUT
TIMER = OFF
2. Fiber optic sensor—
2a) Adjust the open end of the fiber optic sensor cable so that the green
LED illuminates when the carrier tape is present.
2b) Adjust the open end of the fiber optic sensor cable so that the red LED
illuminates and a buzzer sounds when carrier tape is not present.
Pocket Empty Sensor
The Pocket Empty sensor verifies that a pocket is empty as the carrier tape
approaches the Tape Output PNP head location. The sensor shines a fiber
optic light through the small hole in the center of the pocket. If the fiber
optic light is blocked, for example by a device in a pocket, the sensor is trig-
gered. There is no controller that displays this condition.
Problem:
• Error message "Tape Out Unit" displays and no other sensor has trig-
gered an LED.
Check this:
) Adjust the Pocket Empty Sensor. Using an Allen wrench, loosen the
two cap screws that hold the sensor bracket. Move the bracket in the
Y-axis direction until the fiber optic light shines through the hole in the
center of the pocket. Tighten the screws.

Maintenance • (Optional) Automatic Tray Feeder

Automatic Tray
Feeder
The TF20 automatic tray feeder is designed to keep a tray from stopping too
abruptly when it reaches the end of the conveyor nearest the PS288 or the
end of the conveyor nearest the TF20. (Abrupt stops can cause devices to
move on the tray.) You may need to adjust the conveyor speed if trays are
stopping too abruptly.
Conveyor Speed Adjustments
Two sensors control the speed of the conveyor.
• The "Return to Stack" sensor is located near the end of the conveyor
closer to the TF20 stack. When the leading edge of the tray passes this
sensor, the conveyor shifts to slow speed operation.
• The “Place in PS288” sensor is located near the end of the conveyor
closer to the PS288. When the leading edge of a tray passes this sensor,
the conveyor shifts to slow speed operation.
When either sensor is triggered, the conveyor shifts to slow speed operation.
The speed of the conveyor is adjusted with the potentiometers shown in Fig-
ure 5-79.
Figure 5-79—Conveyor speed potentiometers
To adjust conveyor speed:
1. Press the Stop button on the TF20.
2. Adjust “Return to Stack” or “Place in PS288” potentiometer:
• To increase conveyor speed, turn potentiometer clockwise
• To decrease conveyor speed, turn potentiometer counterclockwise
3. Press the Reset button on the TF20.
