Monitoring
For monitoring the pneumatic supply of the actuators, input
I/19 “Ext-Fault” is provided on the plug PLC. In the event of a
fault, this input will switch the Checkbox PLC to fault status
E01 by means of a pressure switch.
Time reaction
Note the following when evaluating the output signals “Actua-
tor...” by means of a higher-order controller:
If the test parts are passed through at a high rate, some parts
may be returned although previously tested parts have not
yet been blown down at the delivery position. This delay ar-
ises due to the (long) distance between the actuator posi-
tions.
Further information on connecting the actuators can be found
in chapter 3.2.
