► 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
