The device has a digital input, TRIP/RESET (Figure 20), to do an external trip or reset.
If this input is activated, the relay is tripped. See “5.2 - TRIP DISPLAY SCREENS”.

The TRIP/RESET digital input works like a status input, meaning if the device is in idle and a voltage
is applied to the digital input, the R1 trip relay trips. The device remains tripped while the digital input
remains activated, Figure 21.
