Example For Signal Input / Output; Connecting The Cable Shield - ABB EBN853 Instruction

9.3

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).

(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.
