Please note
If there is a failure in the power supply to the Checkbox or
to the actuators whilst the transport device is running, this
can lead to the following:
– Parts may pass the actuator positions without being
checked.
– The actuators cannot sort out checked parts.
Ascertain the measures which are necessary on your ma-
chine/system to prevent incorrectly orientated parts or
bad parts from reaching the subsequent machine/system
during such malfunctioning.
Checkbox PLC:
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
E 01 by means of a pressure switch.
The Checkbox can control up to 3 actuators for sorting out
good parts, incorrectly orientated parts and bad parts. Poss-
ible actuators are e.g. separating filters, reversing stations or
blow-down nozzles which sort out the parts at certain posi-
tions on the transport device depending on the result of the
test. The number and assignment of the actuator positions
can vary depending on the application. The assignment of the
actuator positions can be adapted with the CheckKon soft-
ware.
