RESET
How the outputs are reset depends on the "Reset response" parameter (see Chapter "Reset
response (Page 363)").
The following settings can be selected:
● Automatic reset (Memory = O / Mem = no)
The device is reset automatically as soon as a previously occurring error has been dealt
with.
● Manual RESET (Memory = I / Mem = yes)
To reset the devices with digital setting, it is necessary to press both arrow keys
simultaneously for more than 2.5 s after removal of the cause of error. If the cause of the
error has not been removed, a new error message appears immediately. Alternatively,
the devices can be reset by switching the rated control supply voltage on and off.
