Command | Description |
LLO | isables the front panel LOCAL switch. When LLO is in effect you can only |
| return to local mode using the GTL command. You can remove the local lockout |
| with the REN command. See also “Remote/Local Operation” on page |
MASK | isables the supply's previously unmasked operating conditions from setting bits |
<mne ics> | in the fault and status registers. See “Accumulated Status, Status, and Fault |
| R gisters” on page |
| and may be sent in any order. |
| Mnemonics: CV, CC, OV, OT, SD, FOLD, ERR, PON, REM, ACF, OPF, SNSP |
| Note: UNMASK NONE = MASK ALL (Initial value) |
| MASK NONE = UNMASK ALL |
OUT <1/ON>, <0/ Enables or disables the supply’s voltage/current output. The supply will continue to
OFF> | 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 user lines |
| connector, li e 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? | Asks for 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 J65 on the |
| operation. |
|
|
OVSET | Sets the supply’s over voltage protection trip point in volts (default) or in |
<voltage> | 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? | Asks for the supply’s present over voltage protection limit. |
| Response: OVSET <voltage> |
