Steps to Troubleshoot a Film Break Error on the 1400-V

If a Film Break error appears on the RDS controller of your 1400-V machine, follow the steps below to determine whether the film break sensors (Inputs 2 and 4) are working correctly and whether the RDS controller is receiving their signals.

 

Step 1: Manually Rotate the Rollers

Turn the aluminium dispenser rollers by hand to simulate film movement. This should activate (pulse) the film break sensors.

 

Watch Roller Rotation Demo

This video demonstrates how to correctly rotate the rollers to engage the film sensors.

 

Step 2: Observe Input Indicators on the RDS Controller

While rotating the rollers, check the RDS controller screen for input activity:

  • Look specifically at Inputs 2 and 4, which correspond to the film break sensors.

  • As the rollers turn, you should see Input 2 and/or Input 4 light up (on/off) to indicate signal detection.

 

Watch Input Signals on RDS Controller

This shows Input 2 responding to sensor activation as the rollers are turned.

If either Input 2 or Input 4 do not appear on the RDS screen then the signal is not believe received by the controller and a continuity test should be carried out.

Start by ensuring that there is a good connection from the sensor to the harness. You will find this below the tower at the point where the wrap arms meet. There is an access hole here. See image below. 


 

Step 3: Verify Sensor Function

If either Input 2 or Input 4 lights up during roller rotation:

  • Check for dirt or damage on the sensors themselves.

  • Inspect the wiring to ensure a secure connection to the controller.

  • If no issues are found visually, the sensor may need to be tested or replaced.

Step 4: Review General Input Testing (Optional)
