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.

- Remove approximately 2 cm of the
cable sheathing (1) at the cable entry
of the housing (4).
- Open the cable shield in this area
and fold it back over the cable
sheathing (1).
- Insert the cable end in the cable entry
and fasten it with the clamp; make
sure that the shield is folded back
and in contact with the clamp and
the electronics housing.
