2 GP-IB Status Indicators
These four LEDs indicate
the status of the power
supply on the GP-IB.
RMT (green) indicates that power supply is
under remote (GP-IB) control.
LSN (green) indicates that power supply is addressed to listen.
TLK (green) indicates that power supply is addressed to talk.
SRQ (green) indicates that power supply is requesting service from
controller.

3 Power Supply Status
Indicators (Primary)
These four LEDS
indicate the operating
state of the power supply.
One and only one LED
will be on at all times.
CV (green) indicates that the power supply is regulating its output
at a constant voltage.
CC (green) indicates that the power supply is regulating its output
at a constant current.
OVERRANGE (yellow) indicates that the power supply is
operating beyond its maximum output power specification and that
the output is not regulated.
DISABLED (yellow) indicates that the power supply output has
been turned off for one of these reasons:
a. command from controller
b. overvoltage protection
c. overtemperature protection
d. foldback protection
e. low or high ac input voltage
f. remote inhibit (INH)

4 Power Supply Status
Indicators (Secondary)
These four LEDs indicate
the state of protective
circuits within the power
supply.
OV (yellow) indicates that the overvoltage protection circuit has
disabled the output and is latched.
OT (yellow) indicates that the overtemperature protection circuit
has disabled the output.
FOLDBACK (yellow) indicates that the foldback protection circuit
has disabled the output and is latched.
ERROR (yellow) indicates that the power supply has detected a
programming error.
If user attempts to exceed soft limits locally (using RPG), ERROR
will light while RPG is being rotated and will remain on for
approximately 1 second after rotation stops.
For remote programming error, ERROR will turn off when error
query is received.
