24V Logic Power Supply Fault

What does UL mean?

This indicator, when off, shows that the 24V communications power feed-in for the logic section (ULogic) is either completely absent or its voltage level is too low. This critical condition prevents the Axioline F station from operating correctly.

• Absence of 24VDC communications power supply.
• 24VDC communications power supply voltage is below the operational threshold.

Click steps to track your progress.

1. 1

   Measure the 24VDC power supply voltage at the communications power feed-in terminals of the Axioline F station.

2. 2

   Verify the power supply unit providing the 24VDC for correct output voltage and current capacity.

3. 3

   Inspect the power cabling from the 24VDC supply to the Axioline F station for breaks or loose connections.
