temperature as an upper limit is when the unit is in the Constant Temperature mode (See
Constant Temperature Operations section for details).
To change the control mode, press the Exit key. From the resulting screen, select the new constant
parameter using the function keys to the right of the display.
After selecting a control mode and setting the limit and timed run parameters if desired, press the Run
key to energize the power supply output. The power supply output will ramp up to the appropriate
setpoint, while not allowing any limit parameter to be exceeded. If any limit parameter should be
exceeded, then the power supply will crossover control modes, making the limit parameter the
new control setpoint. The run mode display shows the controlled parameter highlighted, and will
automatically change if a crossover has occurred.
To stop a run in progress, press the Run key, the Stop key, or the gray ON/OFF key. The display will
change to “STOP” signifying that the output is no longer energized. To pause a run in progress, press
the Pause key. The display will change to “PAUSE” signifying that the output is no longer energized,
and that the run can be resumed. Pressing Run or Pause resumes the run from the previous point
(i.e. for a timed run). Only a run that has been paused can be restarted. After Stopping a run, or
to change parameters of a (paused) run, you must cycle the control logic off and then back on by
pressing the gray ON/OFF key.
During a run, the display will show the actual values of voltage, current, power, and temperature. The
time value displays elapsed time for an untimed run, or time left for a timed run. The volt-hour value
displays the accumulated volt-hour value for the run.
Constant Voltage Operations
From the mode selection screen, select constant voltage operation by pressing the appropriate function
key located to the right of the display. To get to the selection screen from an operating screen, press
Exit, or cycle the control logic off and then back on by pressing the gray ON/OFF key and selecting
MANUAL. The EPS-3000P-II(V) will display the last saved setpoint for constant voltage mode. To
switch between volts/current/power and time/volt-hours/temperature, press function key F1. To change
a parameter, press the function key located to the right of the display, next to the parameter you wish
to change. The EPS-3000P-II(V) will allow a new value to be entered using the keypad numeric keys.
Press the function key labeled “Enter” to complete the new setting. Press Clear to erase previous
keystrokes. Press Exit to cancel entering a new value. The EPS-3000P-II(V) will not accept a voltage
setpoint outside of the allowed range. Press Clear to re-enter an appropriate value.
The limit parameters are normally set to the power supply maximum values. The EPS-3000P-II(V) will
not accept a limit parameter outside of the allowed range.
In addition, the EPS-3000P-II(V) will never exceed the maximum power output specification of 400W.
Constant Current Operations
From the mode selection screen, select constant current operation by pressing the appropriate function
key located to the right of the display. To get to the selection screen from an operating screen, press
Exit, or cycle the control logic off and then back on by pressing the gray ON/OFF key and selecting
MANUAL. The EPS-3000P-II(V) will display the last saved setpoint for constant current mode. To
switch between volts/current/power and time/volt-hours/temperature, press function key F1. To change
a parameter, press the function key located to the right of the display, next to the parameter you wish
to change. The EPS-3000P-II(V) will allow a new value to be entered using the keypad numeric keys.
Press the function key labeled “Enter” to complete the new setting. Press Clear to erase previous
keystrokes. Press Exit to cancel entering a new value. The EPS-3000P-II(V) will not accept a current
setpoint outside of the allowed range. Press Clear to re-enter an appropriate value.
The limit parameters are normally set to the power supply maximum values. The EPS-3000P-II(V) will
not accept a limit parameter outside of the allowed range.
In addition, the EPS-3000P-II(V) will never exceed the maximum power output specification of 400W.
