AC FAULT
The AC FAULT protection will activate when the internal input voltage is not within the
model’s range, or when a certain input voltage is having an under voltage condition. The
output will turn off that is OUTPUT = OFF for protection.
When AC FAULT occurs the main page will prompt a protection message as Figure 3-89
shows:

Once the AC FAULT is activated, the output is turned off that is
OUTPUT = OFF. Power off the device and then power it on again
after the input voltage spec and connection are confirmed. If any
of the voltage specs or connection is incorrect, AC FAULT
protection will occur continuously.
3.
Be aware that the diameter of input wire cannot be too thin, or the
line loss generated may cause the input voltage out of SPEC and
AC FAULT may occur. See section 2.3.2 for the spec of wire
diameter.
3.3.5.10 SENSE FAULT Protection
The remote sense is located at the rear panel near to output terminal. See section 2.4.1 for
correct connection. When the connection is correct it can adjust the UUT’s voltage to be
consistent with the panel set voltage without affecting by the voltage drop of load wire.
