How to start and stop a sequence
1. The sequence can be started either by tapping or pushing the “On/Off” button, if the DC input is
currently switched off. The sequence then starts immediately with the parameters of the start sequence point.
In case START is used while the DC input is still switched off, the DC input will be switched on automatically.
2. The sequence can be stopped either by tapping or pushing the “On/Off” button. However, there
is a difference:
a) only stops the sequence run, the DC input remains ON with the static values in effect.
b) The “On/Off“ button stops the sequence run and switches the DC input off.
Any device alarm (overvoltage, overtemperature etc.) stops the sequence run automatically,
switches off the DC input and reports the alarm in the display.
In order to exit the sequence generator SEQ after stopping the run with touch area STOP”, the
DC input would have to be switched off rst.
3.8.3.2 Loading and saving of sequences
The device can store one sequence at a time. It is possible to quickly switch to another sequence by loading it from
an USB stick via USB port on the front side of the load module. It accepts USB sticks in FAT32 format and up to
32 GB of storage space. Sticks with USB 3.0 and/or higher storage capacity may work, but this is not guaranteed.
Limitations:
• Generally, all 100 sequence points of a sequence are saved or loaded at once
• The device can only list a max. of 5 sequence les. Those up to 5 les are not necessarily the rst 5 sequence
les in the folder when listed alphabetically. It is thus recommend not to have more than 5 sequence les at
once in this folder.
• If you intend to save the currently active sequence to USB stick and into a new le (-NEW FILE-, see below), it
is only possible if there are not already more than 4 other sequence les in the same folder
For the le name of sequence les there are following requirements:
• The le(s) must be stored inside a folder called HMI_FILES which has to be in the root of the USB driver
• The le name must always start with WAVE_ (not case-sensitive)
For the le format of sequence les there are following requirements:
• The le(s) must contain exactly 100 rows with 4 subsequent, semicolon separated values, i.e. 4 columns when
viewed in Excel or similar
• Values with decimal places can have comma or dot as decimal separator, but only one per value. Example: 1,0
or 1.0 are OK, but 10,000,000 or 10.000.000 is not accepted.
• All values in every row and column have to be within the specied range (see below)
• The columns in the table have to be in a dened order which must not be changed
Following value ranges are given for use in the sequence le with its 100 rows, related to the manual conguration
of the sequence generator (column headers named like in Excel):
Column Parameter Range
A Set value of voltage 0...100% U
B Set value of current 0...100% I
C Set value of power 0...100% P
D Time in milliseconds 1...36,000,000 (36 million ms = 10 h)
