Acknowledging fault modes
Fault modes can be acknowledged by pressing the R (reset / set) button for a long time.
Acknowledging is only possible if the fault mode has been removed.
The fault mode can also be acknowledged by using off the device's voltage for sufficiently
long while the Error Memory setting is in OFF position.
