OPERATING MODE
PLS600 will operate in one of eight modes:
1.0.1
Local
In Local mode, the user controls PLS600 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 rotary
controls 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 rotary controls are disabled and the Output On/Off 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 rotary controls are disabled and the Output On/Off button is recognized only to
enter Setup or to activate/deactivate the output.
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 rotary controls are disabled and the Output On/Off 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.
