Foldback Protection

Foldback protection causes the supply to shut down if the selected
regulation mode is entered and the configured delay time expires. A delay
time may be specified as well. The only way to clear foldback is by
pressing the Rotary knob/Enter button for 3 seconds and executing the
Clear command.
Command:
[:]OUTPut[<channel>]:PROTection:CLEar

Setting the Foldback Mode

The following command will set the foldback mode. The mode selected
by the character mnemonic sent will indicate which mode will trigger the
foldback alarm to begin counting. For example, if the command is sent
with the CV mnemonic and the output is enabled with no load attached
(open circuit), the unit will operate in constant voltage mode and the
foldback counter will begin counting. If the CC mode was set and the
output was enabled with no load connected, the unit will operate in CV
mode and the foldback counter will not trigger.
To set the foldback mode, send the command:
Command:
[:]OUTPut[<channel>]:PROTection:FOLDback {?|CC|CV|NONE}
Where:
NONE indicates foldback protection is disabled.
CC indicates the supply will shut down due to constant current condition.
CV indicates the supply will shut down due to constant voltage.
The default value is NONE.
