7. If you have a three phase configuration and are in the three phase mode, use the PHASE
key to select all three phases. (øABC will be displayed in the top right corner of the screen.)
8. The START ø may be left at RANDOM as we are not interested in starting at a specific
phase angle. If a number is already present in this field, use the BACKSPACE (<-) key to
clear it.
9. Move the cursor to the GO TO VOLT field and enter 160.0
10. Move the cursor to the DUR SCALE field and set this field to TIME. We will be entering
delays in time rather than cycles since this example was stated in ms.
11. Move the cursor to the DURATION field and enter 0.033 seconds. Be sure not to enter 33
as this field is specified in seconds, not milliseconds. The highest time resolution available
for list transients is 1 ms or 0.001 s.
12. Move to the END VOLT field and enter 0.0. We want the voltage to return to 0 Volt after the
first burst.
13. Move the cursor to the END DELAY field and enter 0.067 for a interval delay of 67 ms.
Notice that we effectively combined steps 0 and 1 from Figure 3-46 into a single list event.
14. If you have an CSW Series AC source, move down to the FUNCTION field and use the
knob to select SINE. The knob will allow you to scroll through all available wave shapes in
the active WAVE GROUP. If you have an i Series AC Source, this field will not be visible.
15. Move the cursor to the REPEAT field and enter 0. This means this event will be executed
once and not repeated. Do not confuse this event level repeat capability with the entire list
level repeat field which we will use later.
16. Move the cursor down to the EVENT # field and enter a number from 1 through 99. The
transient list will be executed in order of event number. Leaving a gap between event
numbers allows you to insert events at different places later in the sequence. Deleting
events is always possible regardless of the event number. For the purpose of this exercise,
we will start with EVENT # 5. Enter 5 and press the ENTER key. This brings you back to the
TRANSIENTS menu.
17. Repeat steps 6 through 16 two more times using 120 V, 83 ms and 80 V, 150 ms as values
for EVENT # 10 and EVENT #15.
18. Once you have programmed these three events, move the cursor in the TRANSIENTS
menu to the START/VIEW SEQUENCE field and press the ENTER key. This will get you to
the START/VIEW TRANSIENT SEQUENCE menu from which you can run transient
programs. This screen shows all available events in the transient list on the right hand side.
If more than five events are programmed, you can scroll through the list using the UP and
DOWN arrow keys. To edit an existing event, move the cursor to the relevant event number
and press the ENTER key.
19. Move the cursor to the REPEAT #0 field and enter 1. This will cause the transient program
to repeat once and thus run two times total. Do not confuse this global list level repeat
capability with the list event level repeat field we skipped in step 15.
20. Make sure the output relay is closed using the OUTPUT ON/OFF key. If you start a transient
program with the relay open, an error message will appear.
