exceeds the maximum surge load capability mentioned in section 3.5.5.
Over temperature
The Load has an over temperature protection circuit, which will turn off the load if
internal temperature exceeds the safe limit. The over temperature status register bit is
set when the OT condition occurs, and will remain set till it is reset. Load will appear
as below when over temperature protection occurs.
Reverse Voltage
The Load can conduct a reverse current when the polarity of UUT connection is not
correct. The maximum safe reverse current is same as the Load rated current. If the
UUT reverse current is over the Load rated current, the Load may be damaged. If a
reverse voltage condition is detected, you must turn off the power to UUT immediately
and correct the connection. The reverse voltage status register bit is set when the RV
condition occurs, and will remain set till it is reset. The Load will appear as below
when reverse voltage alarm occurs.
FAN FAIL
The Load has a fan fail protection circuit, which will turn off the load if any of the four
fans is out of order. The fan fail status register bit is set when the condition occurs, and
will remain set till it is reset. The Load will appear as below when fan fail protection
occurs.
All of the protections or alarms will latch when they are tripped. When any protection or
alarm occurs, the load will turn off the input, and beep till you remove the condition and reset
the protection by pressing
CAUTION
To protect the Electronic Load from possible damage, the input voltage must not exceed the
maximum input voltage rating specification. In addition, the Load + terminal potential must
be more than the − terminal potential.
