Why is the tension unstable in both AUTO and MANUAL modes on my Montalvo Controller?

  Lauren KimAug 4, 2025
  Unstable tension in both AUTO and MANUAL modes on your Montalvo Controller can stem from mechanical or pneumatic issues. Mechanically, check for a bad roll, faulty bearings, bent shafts, worn gears, missing teeth, loose chains or belts, line speed variations, or brake, clutch, or drive problems. Pneumatically, look for fluctuating air input, air leaks, or water/oil in the air lines.

  If the tension is too low in both AUTO and MANUAL modes on your Montalvo Controller, first check the input air pressure and look for any air leaks. The I/P converter may also be defective. Additionally, inspect the terminal points of the regulator; if faulty, consider replacing the circuit board. Finally, the brake/clutch might be too small, not enough pads may be activated, the motor could be too small, or the drive current limit could be set too low.

How to troubleshoot tension and output when stable in MANUAL but unstable in AUTO mode on a Montalvo Controller?

  If your Montalvo Controller's tension and output are stable in MANUAL mode but unstable in AUTO mode, there might be a tuning issue. Check the regulator tuning. Also, examine the regulator's terminal points; if they are faulty, consider replacing the circuit board. If the signal voltage is okay, the I/P converter may need replacement.

Why does tension increase at small roll diameters in AUTO and MANUAL modes on my Montalvo Controller?
- J
  James MccartyAug 27, 2025
  If the tension increases at small roll diameters in both AUTO and MANUAL modes on your Montalvo Controller, it could be due to several factors. The bearings in the unwind might be defective, causing too much friction. The I/P converter could also be defective. Check the regulator's terminal points and replace the regulator if it's defective. Lastly, the brake may be too large, or too many pads could be activated.
