If the power supply does not turn on

To troubleshoot a power-on failure:
1. Verify that the AC power cord is firmly plugged into the power connector on the rear-panel of the
Series 2230G.
2. Make sure that the AC power source you plugged the power supply into is energized, and then
turn the Series 2230G on.
3. Make sure the voltage selector switch is set according to the local voltage (110 VAC or 220 VAC).
Change the voltage setting if it is incorrect.
4. Verify that the correct power-line fuse is installed and functioning. If the fuse is damaged, replace
it with a fuse appropriate for your model of power supply (see the following table).

Self-test procedure

The Series 2230G runs a self-test automatically when it is turned on.
When the Series 2230G is turned on, the display shows the software version number (for example,
BOIS Ver. 1.XX). After approximately one second, the system starts the self-test and the display
shows Initializing....
If the self-test finishes with no errors, the display shows the set voltage value of all three channels on
the first line and the set current value of all three channels on the second line, in the format shown
below.
0.000V
SV0.000A SV0.000A SV0.000A
