Controlling the Output State

The following commands control the power module output state:

Command

OUTP ON

OUTP OFF

OUTP1,NOR

OUTP 0,NOR

OUTP: REL 1

OUTP:REL 0 OUTP:REL:POL NORM OUTP:REL:POL REV

Table 4-1. Power Module Output Commands

Function

Enables the output. Disables the output.

(If an optional output relay is installed, the command is executed in a sequence that prevents "hot switching".)

Enables the output without affecting the output relay. Disables the output without affecting the output relay. Closes the (optional) output relay contacts.

Opens the (optional) output relay contacts.

Makes the (optional) output relay polarity the same as the module output.

Makes the (optional) output relay polarity opposite to the module output. The output is disabled while the relay polarity is being reversed.)

Controlling Protection Functions

The following commands control the power module protection circuits.

Command

CURR:PROT:STAT ON

CURR: PROT: STAT OFF VOLT:PROT <value>

OUTP:PROT:CLE

OUTP:PROT:DEL .05

Table 4-2. Power Module Protection Commands

Function

Turns on the OCP (overcurrent protection), which disables the output if the output current exceeds the programmed current.

Turns off the current protection.

Programs the OVP (overvoltage protection) level. The protection circuit will trip if the output voltage exceeds the OVP level.

Clears any active protection conditions (panel Prot annunciator goes off). Before the command can comply, you must remove the condition that caused the protection circuit to trip.

Specifies a delay (in seconds) between the time a protection condition is detected and the actual activation of the protection circuit. (Does not apply to OVP.)

Controlling Fixed-Mode Output

The following commands control the power module fixed-mode voltage and current output.

 

Table 4-3. Power Module Fixed-Mode Output Commands

Command

 

Function

CURR:MODE FIX

CURR <value> CURR:TRIG <value> MEAS:CURR?

VOLT:MODE FIX

VOLT <value> VOLT: TRIG <value> MEAS:VOLT? VOLT:SENS?

Sets the current mode to fixed (as opposed to list). FIX is the factory default power on state.

Programs the immediate output current level (in amperes).

Programs the triggered output current level (in amperes). See "Trigger Commands". Returns the present value of the output current.

Sets the voltage mode to fixed (as opposed to list). FIX is the factory default power on state.

Programs the immediate output voltage level (in amperes).

Programs the triggered output voltage level (in amperes). See "Trigger Commands". Returns the present value of the output voltage.

Returns the position of the output connector sense switch (INT is local; EXT is remote).
