Fault Indication & Control Status
Chapter Objectives This chapter covers the AEC operation status. Fault states are
separated into four basic categories:
•
Transducer
•
Encoder
•
Internal
•
No Fault
Faults can be attributed to:
•
Improper installation
•
Improper AEC switch configuration
•
Faulty hardware (i.e. broken cable)
•
Improper application
It is the responsibility of the user to make sure that the application is
safe. Understanding the capabilities of the AEC can help you achieve
this goal.
The AEC provides bicolor LED fault indication for each axis. The color
and pattern of these LEDs provide “at-a-glance” indication of the
status of each axis.
Although the AEC is equipped with a Reset button, it is not a
recommended form of fault resolution. If the non-offending axis is
running fine, pressing the reset button could result in a hazardous
situation.
ATTENTION
!
Pressing the Reset Button or Powering Off the AEC
results in both axes being reset. This can cause problems
if one axis is running in a no-fault condition and either of
these procedures is followed to correct a fault on the
other axis.
