Status Flags

Status Flags

The power supply has 5 status flags to indicate the operating state. The S/D LED on the front panel, and 4 LEDs visible from the top of the unit. The flags, listed in order from front to rear, are OTP, OVP, SNS-PROT and AC-FAIL.

OTP	Over-temperature protection indicates a supply shutdown due to
	over-temperature triggering the OTP circuitry. The unit has an
	auto-restart feature when the supply’s temperature is within the correct
	temperature range again.
OVP	Over-voltage protection indicates shutdown due to output voltage
	exceeding the threshold preset using the OVP trimpot on the front
	panel.
SNS-PROT	Sense line protection indicates a shutdown due to a voltage drop on the
	load lines exceeding 5 V per line (3 V per line for 7.5 V model) in remote
	sense mode. This condition may also occur if the unit is operated
	without the J207 default sense line connector.
AC-FAIL	AC fail indicates a mains V ac input out of the supply’s specified range
	(i.e. below 85 V ac or over 264 V ac).

In the event of one of the flags being tripped, the flag is raised along with S/D flag on the front panel. An S/D flag with none of the other 4 flags indicates remote shutdown (J210,1and 2).
