1.0 Bench iLSOperating Modes
1.0.1 Local
In Local mode, the user controls BENCH iLS via the front panel. While in Local mode the
user can achieve nearly full capability via the SCPI command interface, EXCEPT for setting
operational voltage and current setpoints and activating the output. The SCPI command to
deactivate the output will be executed. While in Local mode, the Analog Voltage and Analog
Current inputs are ignored.
1.0.2 Remote
In Remote mode, full capability is available over the SCPI command interface. The front
panel Voltage and Current control knobs are disabled and the Enable button is recognized
only to enter Setup or to deactivate the output. The Analog Voltage and Analog Current
inputs on the Interface board are ignored.
1.0.3 Remote with Lock
Remote with Lock mode is identical to Remote mode, except all front panel capability is
disabled. (That is, the Enable button cannot be used either to enter Setup or to deactivate
the output.) As in Remote mode, the Analog Voltage and Analog Current inputs on the
Interface board are ignored.
1.0.4 Analog Voltage Control
In Analog Voltage Control mode, the output voltage setpoint is provided by the Analog
Voltage input to the Interface board. (The current setpoint is set to the most recent Local
mode setpoint and cannot be changed.) Limited SCPI command capability is provided. The
front panel Voltage and Current control knobs are disabled and the Enable button is
recognized only to enter Setup or to activate/deactivate the output.
1.0.5 Analog Current Control
In Analog Current Control mode, the output current setpoint is provided by the Analog
Current input to the Interface board. (The voltage setpoint is set to the most recent Local
mode setpoint and cannot be changed.) Limited SCPI command capability is provided. The
front panel Voltage and Current control knobs are disabled and the Enable button is

1.0.6 Analog Dual Control
In Analog Dual Control mode, the output current setpoint is provided by the Analog Current
input to the Interface board and the output voltage setpoint is provided by the Analog
Voltage input to the Interface board. Limited SCPI command capability is provided. The
front panel Voltage and Current control knobs are disabled and the Enable button is
recognized only to enter Setup or to activate/deactivate the output. Note that in both OFF
and ON states, the screen displays the current mode in the upper right corner.
1.0.7 Parallel Mode
In parallel mode the analog output is activated and this output is proportional to the output
current of the power supply. When this output voltage is fed to one or more analog inputs of
other supplies and the analog inputs of those supplies are set for Analog Current Control
the supplies will share current equally.
1.0.8 Series Mode
In series mode the analog output is activated and this output is proportional to the output
voltage of the power supply. When this output voltage is fed to one or more analog inputs of
other supplies and the analog inputs of those supplies are set for Analog Voltage Control
the supplies will match output voltages.
1.0.9 Mode Transitions Commanded from Front Panel
You can enter all modes except Remote with Lock from the front panel.
•Press and hold the Enable button for 5 seconds to enter Setup. Release the Enable
button and the Control Source selection screen will appear.
•Press the Enable button again. The Select Control Source (Mode) screen will
appear, with the current mode displayed (for example, LOCAL).
•Turn either knob CW or CCW to select the desired mode and press Enable to
select it.
•From the Control Source selection screen, turn either knob CW to display the Exit
option. Press Enable again.
•The Save Config? screen is displayed, with the Yes option. If the newly selected

1.3 Remote With Lock Mode
Remote with Lock Mode is identical to Remote Mode, except you will have no control
available from the front panel (i.e., it is locked).
Remote with Lock Mode (which cannot be exited from the Front Panel) will not be stored in
non-volatile memory. An attempt to do so will replace it with Remote Mode (which can be
exited from the Front Panel).
1.4 Analog Voltage Control Mode
1.4.1 Voltage Setpoint
When the unit is in Analog Voltage Control Mode, the Analog Voltage channel supplies the
Voltage Setpoint.
Scaling:
You can select 3 volt, 5 volt, or 10 volt scaling for the analog voltage input. This is the value
which represents the maximum model-specific voltage. For example, if you have the 400V
2.5A model and have selected the 10V scaling, then 10 volts applied across the Analog
Voltage channel will result in a 400 volt setpoint. For the same scaling, 5 volts applied
across the Analog Voltage channel will result in a 200 volt setpoint.
If Analog Voltage Control Mode is entered via the front panel, you will be asked to select
which scaling you want. You may also select scaling with the SCPI command:
SYSTem:MODe:ASCale VOLT,<3|5|10>

2.0 Enable/Disable BENCH iLS Remote Sense
You can enable or disable the BENCH iLS Remote Sense capability and set the lead
resistance with the following SCPI commands.
RSENSE Enable/disable Remote Sense
RSENSE? Return Remote Sense state
RSENSE:RESistance Set the remote sense resistance
RSENSE:RESistance? Return the remote sense resistance
2.1 Calculate the Lead Resistance
In addition, you 181,”Resistance too large” can command BENCH iLS to calculate the lead
resistance by executing the following sequence:
1) Short leads which connect to the load at the load.
2) Execute the command to enable Remote Sense
RSENse ON
3) Execute the command to calculate lead resistance.
RSENse:RESistance:CALCulate <current> Initiates calculation
The <current> value is the current, in amperes, at which the lead resistance is to
be calculated and will normally be toward the high end of your application.
If the specified current is greater than the maximum allowed for the BENCH iLS
model you are using, you will trigger the error: -222,”Data out of range”.
4) Execute the command to query the remote sense calculation state.
RSENse:RESistance:CALCulate?
If the calculation is still taking place, BENCH iLS will report: CALCULATING
When the calculation is complete, BENCH iLS will report: COMPLETE
If the calculated resistance is too large for practical application of remote sensing,
BENCH iLS will return the error: 181,”Resistance too large”.
SECTION 2 REMOTE SENSE CONFIGURATION

You can calibrate BENCH iLS over the SCPI command interface. To do so you must execute
a series of steps while opening and shorting the output. These steps may be performed via
the front panel or via SCPI commands. A calibrated high-accuracy digital multimeter (DMM)
and a high accuracy shunt is required to perform calibration.
The sequence of commands is listed below. The sequence must be run to completion. If it is
aborted early either by cycling power or exiting Calibration Mode, you must restart the
command sequence from the beginning.
3.0 Calibration Sequence
1) Remove any load from the output terminals and apply the DMM leads to the
output terminals. Set the output voltage to a low value (recommend 10% of the
rated output voltage) and enable the output. Record the low voltage setpoint.
2) Use the DMM to record the actual output voltage of the supply. Record the low
voltage measured.
3) Set the output voltage to a high value (recommend 90% of the rated output
voltage). Record the high voltage setpoint.
4) Use the DMM to record the actual output voltage of the supply. Record the high
voltage measured.
5) Command BENCH iLS to perform the voltage calibration based on the recorded
values:
CALibration:CALCulate:VOLTage <low voltage setpoint>,<low voltage
measured>,<high voltage setpoint>,<high voltage measured>
All voltages must be in Volts.
6) Disable the output. Let it bleed down to near 0V. Connect the shunt to the output
terminals and apply the DMM leads to the shunt terminals. Set the output current
to a low value (recommend 10% of the rated output current) and enable the
output. Record the low current setpoint.
7) Use the DMM to record the actual output current of the supply. This may involve
dividing a measured voltage by the known shunt resistance. Record the low
current measured.
8) Set the output current to a high value (recommend 90% of the rated output
current). Record the high current setpoint.
9) Use the DMM to record the actual output current of the supply. Record the high
current measured. This may involve dividing a measured voltage by the known
shunt resistance.

BENCH iLS recognizes a number of miscellaneous SCPI commands.
5.0 *CLS
*CLS clears the Event registers of the Questionable Status, Operation Status, Temperature
Status, and Hardware Status Register structures, in addition to the Error/Event Queue.
5.1 *IDN?
*IDN? returns the identification string for this unit. The string will contain, separated by
commas: 1) the company name, Artesyn Power; 2) the model; 3) the serial numbers of the
main and interface boards; and 4) the software revision number for the main and interface
board processors. For example, a 100V 10A model may, in response to *IDN?, return:
“Artesyn Power,Bench 100-10 iLS,031418032001,1.00.0051/1.00.1361”
5.2 *RST
*RST executes a soft reset of the system. The output is deactivated, all error Conditions are
cleared (however, error Events are not), and the unit is returned to its Output Off state. The
operating mode is not changed.
5.3 SYSTem:PROMpt <ON|OFF>
If you are interacting directly with BENCH iLS and would like to have a prompt,
SYSTem:PROMpt enables (ON) or disables (OFF) the SCPI prompt. The prompt is OFF by
default. The prompt is a newline (0x0A) character.
