Check Sensors Procedure (S26-S30, S50)
1. Do GP 6.3. 1
SENSORS Procedure
. Check to make sure all sensors
show “0” on the LCD when uncovered and “1” when covered.
If any sensor shows “1” when uncovered, clean that sensor. Also
check if there is any obstruction in the sensor window.
All sensors show “0” when uncovered and “1” when covered
Yes
- Return to the RTP that directed you here.
No - Go to Step 2
2. Make sure the sensor wire is connected securely at the Sensor Board
and at the Main Control Board (PL 5.27). Do REP 1.5 to remove the
Rear Cover to gain access to the connector at the Control Board.
Refer to Section 7 Wiring and GP 6.22 for details on the Sensor
Cable and termination location.
All the connections are made securely
Yes
- Go to Step 3
No - Make the connection and return to normal operation.
3. Light from sensor components can be viewed with a cell phone
camera, if the sensor is working you will be able to see a bright light.
Alternately a small mirror can be used. Use this procedure to check
that each sensor is emitting a beam of light during operation.
CAUTION: Sensor emits High Intensity narrow angle Infrared
beam (940nm). It is invisible to naked eye, avoid looking directly
at the sensor when the machine is powered ON. See Section 0,
page ix for other languages.
There is no light from any of the sensors on the Sensor Board
Yes - Go to Step 5
There is no light from one or some of the sensors on the Sensor Board
Yes - Go to Step 4
There is a bright light from all the sensors
Yes - Go to Step 6
4. Visually inspect the Cable from the sensor board all the way to the
Control Board (PL 5.27). If the Cable is damaged, replace the Cable.
See Section 7 and GP 6.22 for cable part numbers and locations.
Sensor cable looks okay
Yes - Go to Step 5
No - Go to Step 6
5. Replace the Sensor Board. Refer to REP 3.4 to replace the S26-S30
Sensor Board, and refer to REP 3.5 to replace the S50 Sensor Board.
This clears the fault
Yes - Resume normal operation
No - Go to Step 5
6. Do GP 6.3. 5 FIRMWARE UPGRADE Procedure to Re-flash the
firmware for the eWire.
This clears the fault
Yes
- Resume normal operation
No - Go to Step 7
7. Do REP 11.1 or 11.2 to replace the Main Control Board (PL 5.27).
This clears the fault
Yes
- Resume normal operation
No - Escalate to second level
