Press Shift and Trigger. This switches to the toggled level. Each time a trigger is
sent, the input switches to the alternate level.
NOTE: The difference between programming a toggled level (C:TLEV) and a triggered level (C:TRIG),
is that a toggled level allows you to switch back and forth between the main (or immediate)
level and the toggled level. A triggered level, on the other hand, becomes the main level once it
is triggered. Subsequent triggers have no effect on the input level.
4 - Programming Lists
Lists are the most flexible means of generating complex input sequences. The following figure shows a current
input sequence generated from a list. The input current shown represents three different current pulses (8 A for 2
seconds, 6 A for 5 seconds, and 4 A for 7 seconds) separated by 3-second, 0-ampere intervals.
The list specifies the pulses as three current points (point 0, 2, and 4), each with its corresponding dwell point.
The intervals are three zero-current points (point 1, 3, and 5) of equal intervals. The count parameter causes the
list to execute twice when started by a single trigger.
NOTE: From the Recall Menu, execute the *RST command to reset the load module. This is necessary
because any previously programmed functions remain in effect until cleared.
