Diagnostics and Troubleshooting
This chapter describes the diagnostic process to correct and clear fault
conditions on the 842E-CM encoder. Refer to MOTION-UM003 for more
information.
Interpreting Status
Indicators
The Mod LED shows the device status, the Net LED shows the status of
the CIP connection, and the XS LED
shows the status of the internal
measuring device in the 842E-CM encoder.
Five LED indicators provide status information on the back of the
encoder. The figure below shows their location; the following tables
describe their status.
Read the LEDs according to the following tables.
ATTENTION: Cease operation if the cause of the malfunction has not been
identified!
Stop the machine if you cannot clearly identify the error and/or if you cannot
safely eliminate the malfunction.
