Manual Operation
NOTICE
1. The table below lists the typical value of AC FAULT for 62000P Series:
Less than (Vac)
More than (Vac)
Input Voltage
85.5
275
Table 3-7 AC FAULT Range
2. Once the AC FAULT is activated the output is turned off that is OUTPUT = OFF and
won’t be turned on that is OUTPUT = ON until the input voltage is within SPEC.
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 occur AC FAULT. See section 2.3.2 for
the spec of wire diameter.
3.3.5.7 SENSE FAULT Protection
The remote sense is located at the rear panel near to output terminal. See section 2.5.1 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.
When the connection is wrong for instance:
(1) VOLTAGE SENSING polarity is reversed that is the UUT’s “
－
” terminal is connected
to the “
＋
” of output terminal, and UUT’s “
＋
” terminal is connected to the “
－
” of
output terminal.
(2) One of the VOLTAGE SENSING wire polarity is connected reversely and the other is
disconnected (fallen or broken).
(3) One of the VOLTAGE SENSING wire polarity is connected correctly but the other one
is disconnected.
Wrong connections of the above three will occur SENSE FAULT protection. The output will
turn off that is OUTPUT = OFF for protection. It is necessary to connect the REMOTE
SENSING wires correctly and reset to remove the protection.
When SENSE FAULT occurs the main page will prompt a protection message as shown
below:
