Chapter

Fault Indication & Control Status

Chapter Objectives

This chapter covers the ALEC operation status. There are three status

LEDs on the front panel of the ALEC. These LEDs provide

“at-a-glance” monitoring of the system. The three LEDs monitor

different aspects of the ALEC/AxisLink system. The LEDs are labeled:

AL, CPU OK, and Encoder OK. The following LEDs and status

conditions are covered in this chapter.

• AL LED

• CPU OK

• Encoder LED

• Fault Conditions

AL LED

The AL LED indicates the current state of AxisLink.

Fault states are separated into three basic categories:

• AxisLink Fault

• AxisLink Failing

• No Fault

Faults can be attributed to:

• improper installation

• improper ALEC 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 ALEC can help you achieve

this goal.

The ALEC provides bicolor LED fault indication. The color and pattern

of these LEDs provide “at-a-glance” indication of the status of the

ALEC.

Although the ALEC is equipped with a Reset button, it is not a

recommended form of fault resolution. As the ALEC can be a

component of a larger configuration, pressing the Reset button can
