● Pr. 79 "Operation mode selection" must be set to "4" (external/PU combined operation mode 2).
● Turn the AU signal on.
● Use the RUN key to give a start command.
NOTE For the analog current input (0/4 to 20mA) to become effective for setpoint default setting, the AU
signal on the AU terminal must be activated. This is done, for example, by means of a bridge as
shown in Fig. 5-19.
