Explanation
Indicates the default output current limit setting.
Sets the current limit to .5 amperes. The CC
annunciator is on, indicating that the unit is in
current limit mode and the light bulbs are dimmer
because the output voltage has dropped in its
attempt to limit output current.
You have enabled the overcurrent protection
circuit. The circuit then tripped because of the
output short. The CC annunciator turns off and
the OCP and Prot annuciators come on. The
output current is near zero.
The output is off and the Dis annunciator turns on.
circuit. The Prot annunciator turns off.
The next time the unit turns on it will be restored
to the *RST or factory default state
