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.
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.
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)
