If the PxtRX is not supplied by the DC circuit (DC link) or storage unit, it is possible to
apply an auxiliary voltage of 24 V between pin 1 and pin 2 in the form of an external
power supply. This makes it possible, for example, to parameterise the device inde-
pendently of the supply DC circuit (DC link) or storage unit.
Typical applications:
• Ready-for-operation status
• Warning status
