Operating the Power Supply Locally 3

To re-enable the output after it has shut down, you must disable the Shut-Off signal. In Auto-Restart mode, operation resumes automatically. In Safe-Start mode the Shut-Off function is latched. You must also press the OUT ON button or send an OUTPut:PROTection:CLEar command to resume operation.

The Shut-Off function can be used to shut down multiple power supplies in a daisy-chain fashion as explained later in this chapter. It can also be used to reset the OVP and OCP as previously described.

by the Shut Off function if the Shut-Off input is in the shut-off state. This is

 

because the unit has not detected an on-to-off signal transition.

Enable/Disable terminals are available on the J1 connector to enable

 

or disable the power supply output. This function is level-triggered.

 

Simply connect a switch or relay between J1 pins 1 and 14. This

 

function is activated by SW1 setup switch 9.

 

 

 

These pins disable the output when they are opened. When the

 

output is disabled, the PROT indicator on the front panel will blink.

 

To re-enable the output after it has shut down, you must short the

 

Enable + and Enable – terminals. In Auto-Restart mode, operation

 

resumes automatically. In Safe-Start mode the Enable/Disable

 

function is latched. You must also press the OUT ON button or send
