7Output Control Keys (These twelve keys are output dependent).

Description

OUTPUT SELECT - Selects one of the output channels for local control or display. This key allows the channels to be selected in forward (∉) or reverse (Ð) sequence.

VSET - Displays the selected output’s present voltage setting. The setting can be changed using the numeric entry keys.

ISET - Displays the selected output’s present current setting. The setting can be changed using the numeric entry keys.

OUTPUT ON/OFF - Toggles the selected output on and off. When off, "DISABLED" appears on the display.

OVSET - Displays the selected output’s overvoltage trip point. The setting can be changed using the numeric entry keys.

OVRST - Resets the selected output’s overvoltage crowbar (the cause of the overvoltage must be removed before reset is successful).

OCP - Toggles the selected output’s overcurrent protection circuit on and off.

OCRST - Resets the selected output’s overcurrent condition and returns the output to its previous settings (the cause of the overcurrent must be removed before reset is successful).

channel. The setting can be changed using the numeric

 

entry keys.

 

UNMASK - Displays the present setting of the mask

63, 83

register for the specified channel. The setting can be

 

changed using the numeric entry keys.

 

FAULT - Displays the contents of the fault register for the specified channel. A bit gets set in the fault register when the corresponding bit is set in both the status and mask registers. Pressing the FAULT key also clears the fault register.
