Communication Troubleshooting
Generally:
1. Check the following:
• There is power at the unit
• The LCD shows the relevant data
• The device can be programmed using the handheld programmer
2. Verify that the wiring connections are correct.
Specifically:
If you try to set a SITRANS Probe LU parameter via remote communications, but the
parameter remains unchanged:
• Some parameters can only be changed when the device is not scanning. Try putting
the device in program mode using the operating mode function.
• Try setting the parameter from the keypad. (First make sure that the lock parameter
[P000] is set to the value stored in P069.)
• The communications control parameter P799 must be set to 1 to be able to write
parameters to SITRANS Probe LU.
