Power Supply Settings

Local Lockout (LLO) Command

Use the Local Lockout command to disable the LOCAL button on the power supply front panel. With LLO in effect, you cannot return to local control by pressing the front panel LOCAL switch. You can still return to local mode by sending the Go to Local (GTL) command. However, to turn off LLO and return the power supply to local mode, send the REN OFF command. Only the REN OFF command will remove the LLO condition.

Example:

LLO

GTL

Return the power supply to local mode.

 

Local Lockout is still in effect

REN OFF

Turn off Local Lockout and return the

 

power supply to local mode
