4.3.5 Actuators
Please 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 con
nected 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−P/..X to fault status E01 by
means of a pressure switch.
Time behaviour Note the following when evaluating the output signals Actua
tor..." by means of 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.
