Troubleshooting Signal Errors
While building the FB diagram, or during operation, there may be occasions when the signal
from the transmitter of a FB is displayed yellow. This may reflect that the FB has encountered
an error or some other anomaly has occurred. From the user perspective, an evaluation of the
cause should be done to ensure that unexpected operation does not occur. Suggested steps to
evaluate the cause of a yellow link are listed below:
To evaluate the cause of a yellow signal:
1. Trace the yellow signal back to the source
(first occurrence of a yellow link) FB.
2. Place the mouse over the signal which
will display the error.
3. In this particular example, the error is identified as an Open sensor.
4. Click on the selected FB and view the Help window.
5. Search ("Ctrl-F") the help file for the word "Open".
6. Once found, evaluate, make note or correct the cause of the problem.
If further assistance is needed review the associated product User's Guides or contact the
Watlow Technical Support team (1-800-492-8569 or 1-507-494-5656).
