Example for signal input / output
(conventional analogue / binary control)
Premises to switch the actuator into automatic mode (AUT):
- digital inputs D1, D2, and D3 may not be activated via the configuration software (standard config-
uration 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.
