(1) When the connection is wrong, for instance the VOLTAGE SENSING polarity is
reversed that means the
UUT’s “–” terminal is connected to the “+” of output terminal,
and UUT’s “+” terminal is connected to the “–” of output terminal.
(2) When the voltage drop of load wire is exceeding the full scale of output voltage for 4%,
for instance taking the example by 62150H-600S, the protection will occur when the load
wire voltage drop > 600 x 0.04=24V.
SENSE FAULT protection will occur when these two situations are encountered. The
output will turn off that is OUTPUT = OFF for protection. It is necessary to connect the
REMOTE SENSING wires correctly and reboot to remove the protection.
When SENSE FAULT occurs the main page will prompt a protection message as Figure
3-90 shows.

3.3.5.11 FANLOCK Protection
Fans are built-in inside the DC Power Supply to ventilate the heat generated by components.
If one of the fans is failing (not running), FANLOCK protection will occur and the output will
turn off that is OUTPUT = OFF for protection.
When FANLOCK occurs the main page will prompt a protection message as Figure 3-91
shows:
V = 6 0. 0 0 V I = 1 0. 0 0 _ A O F F
