When the Prot annunciator comes on, press to see which protection circuit caused the
power supply to shut down. Response can be OC (overcurrent), OT (overtemperature), or OV
overvoltage). If no protection circuit has tripped, the display will show dashes (-- -- -- --)
Press this key to reset the protection circuit. If the condition that caused the circuit to trip has been
removed, the Prot annunciator will go off.
Press to enable or disable the power supply OCP trip circuit. This key toggles between the to states .
