3.8.3 Manual operation
3.8.3.1 Accessing and conguring the sequence generator
Viathetouchscreenthesequencegenerator(SEQ)canbecalledup,congured
andcontrolled.Selectionandcongurationareonlypossiblewhentheinputis
switched off.
► How to access the SEQ
1. Make sure the DC input of the load module is switched off.
2. Tap the touch area on the main screen and in the menu tap on
and then .
3. TherstscreenoftheSEQwillalwaysbethesequencepointselection,as
shown in the example to the right.
► How to congure a sequence point
1. Ifthereisoneorseveralsequencepointstocongure,selecttherstonein
the screen “Seq. point select” by using the rotary knob and start editing it
by tapping on touch area “Edit”. The edit screen for the selected sequence
point will be loaded (see example to the right).
2. Adjust the values for U, I and P, as well as the time, with the rotary knob
as usual. Direct input is not available here. Selecting a different value is by
tappingonit.ThetimevaluedeneshowlongthesettingsforU,IandP
are valid when processing the particular sequence point.
3. Onceyouarnishedwithsettingapoint,youmaychosetosavethechangesandreturntotheselectse-
quence point screen by tapping “SAVE” or if you are going to edit subsequent points (next or previous), use
the two touch areas “Prev.seq” and “Next seq.”.
Following adjustment ranges apply for the parameters of all sequence points:
Parameter Adjustment range Description
U 0...U
Nom
Voltage set value of the sequence point over the given time
I 0...I
Nom
Current set value of the sequence point over the given time
P 0...P
Nom
Power set value of the sequence point over the given time
Time 0,3 s ... 36000 s Period of the sequence point in seconds
The adjustment limits (“Limits”) do not apply here. The time of all sequence points sums up to the total run time
of one sequence cycle. With this, a minimum time of 300 ms (1 sequence) and a maximum time of 1000 h (100
sequences.
► How to congure the sequence
1. In the screen “Seq. point select” (see above) tap on touch area “NEXT”.
This will open screen “Sequence control” (see example to the right).
2. Select the block of sequence points to process for the next run by setting
therst(Start seq.) and last (End seq.) point.
3. Also set the number of Seq. cycles(1-999orinnite).
4. Conrmyoursettingswithtoucharea“NEXT” or abort with “ESC”.
Withtappingon“NEXT”,thedevicewillnallyloadthesequence,switchtotheactualsequencegeneratorscreen
SEQ.Thesequenceruncannowbestarted.
If any of the sequence points in the block has not explicitly been set while conguring the points,
it will either have default values (U = 0, I = 0, P = 320 W, t = 0.3 s) or the ones which have been
set the last time.
