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 o.
