74 Operating Manual for XDC Series Power Supply

Shutdown vs Protection Alarm

If a protection setpoint is exceeded, the system does the following:

1. If S/D if tripped? Y has been selected, the unit shuts down.

If it is an OVP alarm, the unit shuts down.

2. If S/D if tripped? N has been selected, and it is not an OVP alarm, the

unit does not shut down but does create an alarm message.

3. If the unit is not shutting down, the system still sets the appropriate status bits in

the questionable status register, which can be queried remotely. See “Status

Registers” on page 142 for more information.

Set Up

Remote

Control

The power supply can be controlled locally with the front panel or remotely through

several different interfaces. The remote interfaces are discussed in Section 4,

“Remote Operation”, Appendix B. “SCPI Command Reference”, and Appendix D.

“GPIB”.

The factory default remote control setting is RS-232. It has a default configuration

of 9600 baud.

Toggl e

Local/Remote

The LCL/RMT key allows you to shift between local and remote control.

To shift from local to remote control:

In the case shown, the power supply has changed from local, front panel control to

remote control through its RS-232 port. The remote control options are RS-232,

Analog V and I, Analog V, Analog I, GPIB, and Linked. You can change the remote

control source through the REMOTE SELECT menu option. (See “Select Remote

Control Source” below.)

There are 2 exceptions to this function:

•If the power supply has Local Lockout (LLO) active, it will not let you shift from

remote to local control. Instead, the display will show LLO on, and the system

will remain in remote control.

•If the system is using GPIB, it will shift to remote control only when the Remote

enable line, REN = 1 and a command is sent from the remote controller.
