Example for signal input / output
(conventional analogue / binary control)
Procede as follows to switch the actuator into automatic mode (AUT):
- activate digital inputs D1, D2, and D3 using the configuration software (standard configuration with
default factory settings).
- activate the AUT mode using the configuration software (standard configuration with default factory
settings).

Behind a step controller
(binary control without an analogue setpoint)
Contrac actuators feature smooth and continous operation even if the elctronic unit receives binary
commands from a step controller. Use the configuration software for the appropriate settings. The elec-
tronic unit will then integrate the step commands and internally generate an analogue setpoint signal.
