If open sense leads or capacitive loads outside the allowable range
cause the output to oscillate, the oscillation protection function
detects the oscillation and latches the output off. The condition is
annunciated on the front panel by the OSC status annunciator.
Front Panel:
Select Protect\OSC.
Check the OSC box and press
Select.
If an over-voltage, over-current, over-temperature, power-fail
condition, power-limit condition, protection condition, or inhibit
signal occurs, the power system turns off the affected output channel.
The appropriate operating status indicator on the front panel will be
on. To clear the protection function and restore normal operation,
first remove that condition that caused the protection fault. Then,
clear the protection function as follows:
Front Panel:
Select Protect\Clear.
Select the Clear button.
