The factory settings of the PCU card are normally set according to the customer requirements at the
time of order. However, we strongly recommend that input power, signal input selection and DIP switches
are to be verified prior to the actuator start up.
Settings the PCU functions are shown in paragraph 4.9.4 and 4.9.5.
