The ALr CLr message will be displayed on the front panel for a few
seconds.
2. Repeat the alarm clearing until you have cleared all alarms.
Clearing a Flash Failure Alarm
The Flash Failure alarm is the only exception for clearing alarms. Flash
failure can only be cleared by a reset (see “Resetting the Power Supply”
on page 3–38) or by power cycling the unit.
To clear a triggered alarm, use one of the following methods:
• Turn the power supply Off and then On.
• Press and hold the Rotary knob/Enter button for 3 seconds.
• Press the reset key combination (Flash Fail ONLY). See “Resetting
the Power Supply” on page 3–38.
The SCPI command (s) for these instructions are:
[:]OUTPut[<channel>]:PROTection:CLEar
Important:
When an alarm is cleared by using this method, only the current
highest precedence alarm is cleared. If another alarm has occurred, then this
alarm will now become the highest precedence alarm and will begin blinking on
the display.
