3.6.5 Actuators
Note
This chapter contains supplementary information on con-
trolling the actuators via the PLC interface. Note also the
instructions and information in Chapter 3.2.
Internal circuitry The inputs actuators 1 ... 3 at the PLC connection are
connected internally with the ACTUATORS connection.

Monitoring Input I/19 on the PLC plug is intended for monitoring the
pneumatic supply to the actuators. In the event of a fault this
input will switch the CHB-C-X to fault status E 01 by means of
a pressure switch.
Runtime performance Observe the following when evaluating the output signals
“Actuator...” through a higher-order controller:
With a high pulse rate of the test parts, parts can be returned
although other parts which have already been tested are not
yet delivered. This delay arises due to the (long) distance
between the actuator positions.
