Remote/Local Operation

Release 3.1 29

Local Mode

Operation

In local mode operation, you set the voltage and current output levels and the OVP

trip level with controls located on the front panel. Refer to the operating manual for

a description of the functions available at the front panel.

While in local mode operation, you can change power supply control to remote

mode by ensuring that REN is ON, then sending any software command and OUT

ON to restore the output. Return to local mode by pressing the front panel LOCAL

button, unless Local Lockout is in effect. If LLO is in effect, use the GTL command

to send the power supply into local mode, or use the REN OFF command to turn

off LLO and return the power supply to local mode.

Example:

Remote

Enable (REN)

Command

You can use the Remote Enable command to toggle between local mode and

remote mode. The default setting at startup is REN ON. With the remote enable

command set at REN ON, you can return the power supply to remote mode

whenever you send any command from the computer. Any time that you change

from local to remote mode during a session, the output is programmed to turn off,

since the remote mode settings may be different from the local mode settings. Send

the OUT ON command to restore the output.

You can turn off Remote Enable and move power supply control to the front panel

by sending the REN OFF command. If the Local Lockout condition is in effect,

sending the REN OFF command will turn off the LLO condition before sending

the unit into local mode.

To check whether the power supply is remote enabled, use the REN? query

command.

Example:

Press the LOCAL button Set unit to local mode

Id? Put the unit into remote mode

(Use any command to do this.)

Press the LOCAL button Return to local mode.

REN ON Enable the power supply to be sent into

remote mode

VSET 10;ISET 2 Put the unit into remote operation mode

(Use any command to do this.)
