Stop Alarm
When the system encounters an overload, short-circuit, over-temperature, over-current,
or power/power-factor beyond the preset limit, the unit will shut down. Output power
will turn off, and an alarm will sound. The FAIL LED (on the FREQUENCY display)
will flash and the PROTECT LED (on the FREQUENCY display) will light (indicates
over-load, short-circuit or over-temperature). Pressing the RESET button (on the
MULTIMETER display) once will disable the alarm, pressing it again will reset the
error message and return the unit to standby status.
NOTE: Please determine the cause (source) of any alarm and correct the
problem — before pressing TEST — to start the output again.
Lock Button
Pressing the LOCK/LOCAL button (on the MULTIMETER display) will light the
LOCK LED (on the CURRENT display) and disable the other controls, except the
METER button (on the MULTIMETER display). Pressing the LOCK/LOCAL button
again unlocks the front panel. This procedure is used to avoid accidental adjustments
to the system.
