FIGURE 3-12. ADDING MULTIPLE STEPS (RAMPS) TO LIST
Execute the List. Steps may be added to a list using Add to List, Current Ramp or Voltage
Ramp buttons, however the total number of steps can not exceed 100. To execute the list, enter
the number of times the list is to be executed in the Loops box (1 to 65536; 0 is continuous
looping), set the output on (click the On/Off button if necessary) and click the Execute List but-
ton. While the list is running, the title of the Execute List button changes to Stop Execution.
After the completion of the specified number of LIST cycles, the output stabilizes at the condi-
tions in the last LIST step.
Stop the List. If the Stop Execution button is clicked to stop the list, the output stays on with
the voltage and current at the list values prior to the stop command, and the Stop Execution
button reverts to Execute List. If the Execute List button is clicked again, the list restarts from
the beginning. If the list is stopped by clicking the *RST button, the output turns off and Output
setpoints are reset to 0V, minimum current, except that if last setting recall (PAR. 3.2.10.3) is
enabled, the Setpoint values are from the last setting.
3.3.6.6.6 SETTING VIRTUAL MODEL [E-SERIES MODELS ONLY]
Refer to PAR. 3.2.9 for details about what Virtual Model means for KLP and how the virtual
model affects other parameters. Click VIRTUAL MODEL (Figure 3-7) to open the Virtual Model
dialog box (Figure 3-13). The current virtual model settings (gray) are displayed. To change the
settings enter the Unit Password (see PAR. 3.2.8) and press ENTER key on the computer key-
board. After the password is accepted, the Unit Password field is inaccessible (gray) and the
Maximum Voltage and Maximum Current fields can be changed. Enter the desired maximum
voltage or maximum current; the other field will be filled in automatically for a maximum of 1200
Watts, then press ENTER key; all fields are gray for a second or two while the power supply
accepts each entry. The Password field is reset after leaving the Virtual Model dialog box
Setting a new virtual model resets the setpoints to zero Volts and minimum Amperes and resets
the OVP and OCP values to 120% of virtual model maximum. A minimum programmed current
is required to ensure proper operation of the power supply under all load conditions. Pro-
grammed current is automatically set to be at least the minimum current (actual value depends
on model, see Table 1-2). If DIP switch position 3 is enabled (see Table 2-2 and PAR 3.2.10.3),
stored setpoints for voltage and current are cleared when the virtual model settings are saved.
