7.1 Protection Function
The APS-1102A is equipped with a protection function that monitors the internal status and displays an
error or warning when it detects the following types of abnormalities.
If the beep sound has been set to on, a beep will accompany the displayed error or warning. (A beep
sounds whenever a protection function-related error occurs, regardless of the beep sound setting.)

When output overvoltage or output overcurrent is detected, output will be set to off and the error
message will be displayed.

warning message will be displayed. If it is an error that occurred, all operations will become disabled
except for the power shutdown operation.

message will be displayed. If it is an error that occurred, all operations will become disabled except for
the power shutdown operation.
