(2) The voltage drop across the load wire exceeds the full scale output voltage by 4%,
protection will occur when the load wire voltage drop > 600 x 0.04=24V (using the
62150H-600S as an example).
SENSE FAULT protection will turn OFF the output if either of these two situations occurs.
Connect the REMOTE SENSING wires correctly or increase the load wire size and reboot to
remove the fault.
If a SENSE FAULT occurs, the MAIN PAGE menu will display a protection message as
shown in Figure 3-90 shows.

3.3.5.11 FANLOCK Protection
Fans are installed inside the DC Power Supply to ventilate the heat generated by components.
If one of the fans fails, FANLOCK protection will occur and the output will turn OFF.
If a FANLOCK occurs the MAIN PAGE menu will display a protection message as shown in
Figure 3-91.
