Xantrex Technology GPIB-M-XPD, GPIB-M-XHR, GPIB-M-XT, GPIB-M-XFR3, GPIB-M-HPD Protection SHUTdown

Status Registers

Overview

SHUTdown The Shutdown sub-register indicates the cause of the power supply shutdown. More Sub-Registerthan one bit may be active, and multiple actions will be required to enable the output.

The protection shutdown sub-register indicates which protection mechanisms have caused the power supply to shutdown.

	9	512	FOLDback		Foldback protection has tripped
	10	1024	Output Fail		The power supply is shutdown by a
					hardware circuit that monitors the output

and compares it to the setpoint. Shutdown could indicate a bridge failure. A temporary condition may be caused by transients.

Remote This identifies which remote interface is controlling the unit. Only one bit is active CONtrol at a time with the exception of analog control, where voltage or current alone, or both

Sub-Registermay be under remote control. Current share mode is considered to be under local control, even though the user cannot adjust the voltage setting from the front panel.
