Displays at the transfer position

3-14
The number and arrangement of the delivery positions can
vary depending on the Checkbox version. The following dia-
gram refers to the standard configuration set at the factory.
Standard transfer positions of the Identbox/Countbox on a
conveyor unit with 2 reject positions
The compressed air valves of the reject positions are con-
nected directly to the outputs actuators 1...2. These outputs
are set at + 24 V DC if the parts test delivers the following
result:
– incorrectly orientated or superfluous (good) part
– bad or foreign part.
If the Checkbox recognizes a test part as a good part,
pin O/30 (actuator 3) will be set from rest potential 0 V to
+ 24 V DC.
Signal level: Actuators 1...3
Connection "Controller" of the Identbox/Countbox
Actuator 1 The + 24 V DC signal is present when the
test part passes the reject nozzle for incor-
rectly orientated or superfluous good
parts. The duration of the signal corre-
sponds to the time the part requires to
pass the nozzle.
Actuator 2 The + 24 V DC signal is present when the
test part passes the reject nozzle for bad
or foreign parts. The duration of the signal
corresponds to the time the part requires
to pass the nozzle.
Actuator 3 The + 24 V DC signal is present when the
good part passes the end of the system
edge (guide rail of the conveyor unit).
