6.8 Indicator elements and signal outputs

6.8.1

LED indicators and display

The lubrication unit LU 2 has three LED indicators. The indicators are placed around

the drive and visible from all sides. System status and errors are displayed via these

LED indicators. All three LED indicators have an identical function.

The system states and errors are also shown in the display.

outputs

In addition, the lubrication unit LU 2 has signal outputs

and

Err

These outputs can be evaluated by a connected controller to monitor the lubrication

unit. System state conditions and faults can be detected.

6.8.3

Cable break detection

The lubrication unit monitors the signal outputs

and

Err

for cable breaks.

If a cable break is detected by the signal outputs, the plug symbol disappears from

the display.
