at any time by pressing the desired command mode button on the HMI screen.
The DC Converter will immediately switch to the new Control Mode.
Example: the test is in Current Control Mode (CURRENT mode is highlighted) with
output readings of 300 VDC, +50 ADC and 15 kW. If the Voltage Mode button is
pressed, the DC Converter will change to Voltage Control Mode (Voltage Mode
is highlighted) and begin controlling at 300 Volts. The voltage setting can then be
adjusted as necessary.
During the test, modes can be changed between Voltage, Current, Power, and
Resistance as often as needed. Each time, the DC Converter will make the change
such that the same operating point is maintained.
4.9.1.4 CHANGING OPERATING LIMITS
The Operating Limits originally set can be changed while the test is running. This
is done with the same steps as they were initially set.
1. Press the UPPER LIMIT text box to input dialog box.
2. Enter the desired value and press ENTER.
3. Repeat for lower limits, if necessary.
Before changing Operating Limits, be sure to carefully
consider the potential impact on the load. It is best to
maintain an Operating Space that is as small as possible
to prevent unwanted or unsafe operation.
4.9.1.5 PAUSING A TEST
To pause a test while in local operation, either control current or power to zero or
enter Standby Mode (HMI STOP button) (see Figure 23). For brief pauses, it may
be more convenient to reduce current or power to zero (see Adjusting Setting
above). For longer pauses and/or for maximum safety choosing, Standby Mode is
recommended.
