Operating Manual for GPIB for XT/HPD Series Power Supply

Command

Description

OUT <1/ON>,<0/OFF>

Enables or disables the supply’s voltage/current output. The supply will
continue to accept new commands while the output is disabled but these
will not be implemented until OUT ON or OUT 1 is received. OUT ON is the
default setting. When you start the supply in remote mode, the output is
enabled.
OUT OFF (or OUT 0) also sets the isolation signal on the rear panel J7
connector, line 3. You can use the to trip external relays to isolate the power
supply from the load.
Initial value: OUT ON (or OUT 1) for output enabled

OUT?

Returns the present enabled/disabled status of the supply’s output
voltage/current.
Response: OUT 1 output enabled or

OUT 0 output disabled

OVCAL

Causes the master controller to perform automatic calibration of the
supply’s over voltage protection circuitry. Set CMODE ON before using this
command. Ensure jumper J217 on the GPIB Interface PCB is connected for
remote operation.

OVSET

Sets the supply’s over voltage protection trip point in volts (default) or in
millivolts. If the trip point is exceeded, or if the trip point value is lower than
the present output voltage setting, the supply will ignore the command, turn
on the ERR LED, and set the ERR bit in the accumulated status register.
Reset with the RST command.
Range: 0 to 110% of model maximum output voltage (VMAX)
Initial value: 110% of model VMAX

OVSET?

Returns the supply’s present over voltage protection limit.
Response: OVSET

ROM?

Returns the version number of the master and slave EPROMs located on
the interface PCB.
Response: ROM M: S:

RST

Resets the supply to present voltage and current settings if the output is
disabled by over voltage or foldback protection. Output values may be
changed via VSET, ISET, and OVSET while the unit is disabled, but those
values will not take effect until RST is applied.
