Front-Panel Operation Overview

The following section describes an overview of the front-panel keys before operating your power supply.

•The power supply is shipped from the factory configured in the front-panel operation mode. At power-on, the power supply is automatically set to

operate in the front-panel operation mode. When in this mode, the front- panel keys can be used. When the power supply is in remote operation mode,

you can return to front-panel operation mode at any time by pressing the Store (Local) key if you did not previously send the front-panel lockout

Local

command. A change between front-panel and remote operation modes will not result in a change in the output parameters.

•The power supply has two output ranges. This feature allows more voltage at a lower current or more current at a lower voltage. The desired output range is selected from the front panel or over the remote interfaces. The 8V or 20V for the E3633A and 25V or 50V for the E3634A annunciator indicates the presently selected range.

•When you press DisplayLimit key (the Limit annunciator blinks), the display of the power supply goes to the limit mode and the present limit values will be

displayed. In this mode, you can also observe the change of the limit values when adjusting the knob. If you press the DisplayLimit key again or let the display time-out after several seconds, the power supply will return the display to the meter mode (the Limit annunciator turns off). In this mode, the actual output voltage and current will be displayed.

•The output of the power supply can be enabled or disabled from the front panel by pressing OutputOn/Off key. When the output is off, the OFF annunciator turns on and the output is disabled.

•The display provides the present operating status of the power supply with annunciators and also informs the user of error codes. For example, the power supply is operating in CV mode in the 8V/20A* or 25V/7A** range and controlled from the front panel, then the CV and 8V* or 25V** annunciators will turn on. If, however, the power supply is remotely controlled, the Rmt annunciator will also turn on, and when the power supply is being addressed over GPIB interface, the Adrs annunciator will turn on. See “Display Annunciators’ on page 5 for more information.
