Note/Illustration Action
Remove the jumper between Pin 1 & 2 and place
one cable from the limit switch into pin 1 and the
other into pin 2. 3
Start the IRC5 controller. If the "Error 20209 - Ex-
ternal Contactor Open" is generated, check the
cable connection between A43:X22 and the limit
switch. Ensure that the limit switch is normally
closed. 4
If all the pairs of Pins in A43:X24
are used, then place the limit
switch 1 and limit switch 2 in series
to an existing chain. Repeat the above step for the limit switch at the
other end of the FlexTrack. 5
Note
The limit switch has 1 normally open contact and 1 normally closed contact. The
normally closed circuit should be connected to the A43:X24 terminal.
Tip
• If the limit switch is triggered by the carriage, it will not be possible to jog
the carriage away from the limit switch. In this case, release the brake and
manually push the carriage away from the sensor. Then update the revolution
counters before attempting to run the track when necessary.
• For more information, please see Product manual - IRC5 .
Option 2 - Wiring the limit switch into the safety PLC
Note
This option should be used for more complex systems where a safety PLC is
controlling the complete station and additional safety to guarantee that the
carriage does not go beyond the software limits set in the controller.
Operating Principle
When the limit switch is triggered, it will open a circuit that is constantly monitored
by the safety PLC. Additional logic should be programmed in the PLC react
appropriately, such as shutting off the power to the motors.
Tip
For details on how to connect to the safety PLC, please review the Product
specification - PLC robot controller .
