The CHB-C-X can control up to 3 actuators for sorting out
good parts, incorrectly oriented parts and bad parts. Possible
actuators are e.g. shunts, reversing stations or air nozzles
which sort out the parts at certain positions on the
transporting device depending on the test result. The number
and assignment of the actuator positions may vary depending
on application. The assignment of the actuator positions can
be adapted with the CheckKon software.
Example of configura tion Transporting device with 2 blow-
out nozzles (see Fig. 1/1)
The compressed air valves of the blow-out positions must be
connected directly with the outputs for actuators 1 ... 2.
These outputs are set to +24 V DC if the parts test provides
the following result:
– incorrectly oriented or superfluous (good) part
– bad or foreign part
If the CHB-C-X recognizes an inspection part as good,
the signal actuator 3 will be set from the rest potential
0 V to +24 V DC and the good part will be output at the end of
the transporting device.
Output
Signal level
1)
(example of configuration)
Actuator 1 There is a +24 V DC signal when the inspection
part passes the ac tuator position for incorrectly
oriented or superfluous good part s.
Actuator 2 There is a +24 V DC signal when the inspection
part passes the ac tuator position for bad or
foreign parts.
Actuator 3 There is a +24 V DC signal when the inspection
part passes the ac tuator position for good parts
(here: the end of the transporting device).

The duration of the signal corresponds to th e time required for
the par t to reach the air jet nozzle.
