	Operation
	Command Reference
Command	Description
DLY <seconds>	Sets a programmable time delay employed by the supply before reporting
	fault conditions. The power supply uses the time delay after receiving a new
	output voltage or current setting via VSET or ISET, or after receiving RST,
	TRG, or OUT ON commands. During the time delay, the power supply
	disables CV, CC, and FOLD conditions from generating faults, preventing
	possible nuisance foldback if the supply momentarily switches modes while
	changing an output setting.
	Range: 0 to 32 seconds, with 32ms resolution
	Initial value: 0.5 second
DLY?	Returns the setting of the programmable time delay before the supply
	reports fault conditions.
	Response: DLY <seconds>
ERR?	Returns the most recent remote programming error. When the power supply
	detects a programming error, it lights the ERR LED and sets the ERR bit in
	the accumulated status and fault registers. If the error bit has been masked
	using the MASK command, then the ERR bit in the registers will not set.
	Once an error is detected, the remaining portion of the command line is
	discarded. An error query clears the ERR bit in the accumulated status
	register. See “Error Codes” on page 51.
	Response: ERR <error number> Example: ERR 0 (if no error)
FAULT?	Returns the state of the fault register. A bit is set in the fault register when a
	fault arises for that condition. Lists the conditions which activate a fault bit.
	You can use the MASK command to disable bits from being set in the fault
	register.
	When a bit is set in the fault register it also asserts a signal on the J7-4 user
	signal line. You can tie the J7-4 fault line signal to the power supply's own
	External Shutdown user line, J7-1, so that the shutdown signal goes low
	(active) in the case of a user-defined fault.
	The FAULT? query clears bits in the supply's fault register and fault line.
	Response: FAULT <fault mask> where fault mask is the decimal equivalent
	of the total bit weights for the operating conditions as listed in the fault
	register. See “Accumulated Status, Status, and Fault Registers” on page
	49.
FOLD	Sets foldback mode for the supply. Foldback protection disables the power
<2/CC>, <1/CV>,	supply output when the output enters the fold condition. Reset with the RST
<0/OFF>	command.
	Example: Specify FOLD 1 or FOLD CV (Constant Voltage) when you want
	the supply to operate in Constant Current mode and have foldback
	protection disable the output if the supply switches to Constant Voltage
	mode.
	Initial value: FOLD 0/OFF
