Issue:

What can cause an Internal Error 10 on the ATS480 soft start?

Product Line:

ATS480

Environment:

INF10 fault

Cause:

n/a

Resolution:

Would suggest to power down the soft start and recheck all the internal connections.

This error is triggered if the external +24vdc supply voltage is higher than 30v, or lower than 19v.

This fault can also occur if the 24v output current is greater than 200ma.

Measure the +24v to com on the soft start.

Check the +24Vdc supply or the current requested by the load connected to the output +24

Recheck the wiring: Previous wiring of ATS48 (+24 and LO+) is at the same location (+24 and 0V) for ATS480.

Do not connect LO+ from ATS48 to 0V of the ATS480.
