Application

The heater burn-out detection system is intended to immediately detect a heating element fault and stop the production of items that do not comply with quality requirements. In response to market needs, we engineered a fully functional and stand-alone heater burn-out detection system for pallet marking machines (used to burn manufacturer and type information). As a result of an innovative approach, our product is easy to assemble and ensures that the cost of upgrading and designing the automation of new machines is minimized.

Easy to implement and operate, the heater burn-out detection system works with heaters of any rated output.

Our product can be applied in a wide range of industries where a heating element operation has to be controlled.

Advantages of the product

  • Very easy to assemble.
  • Little modification of the machine's electrical system is required.
  • Measuring the heaters' current does not involve adding extra contact devices into the heaters' current path, which could lead to an increased failure rate.
  • Overheating of heaters as a result of a burn-out of a heater with a sensor is eliminated.
  • Minimizing the number of thermoregulators, as only a single thermoregulator is required for a given group of heaters.

The kit consists of:

  • Current transformer — supporting six heaters in standard, used to measure current passing through the heaters.
  • Transformer controller — supervises the current transformers.
  • LED indicator — reports the current status of the heaters.
  • An audio signalling device.

 


Operating principle

Phase wires of the heaters need to be passed through the current transformers. The controller monitors currents passing through each heater. When a problem is detected, depending on its nature (the heater has burnt out or its contactor has stuck), the controller reports it via a LED indicator and an audio signalling device. The controller works off-line without modifications of the program in the machine's PLC.

Sorting optimization

Optimizing saw automation system for wood industry In order to maintain optimal times of processing an algorithm for sorting planks cut from maximum 5-metre-long raw material with the least possible amount of waste, an external module was used, based on a microcontroller which communicates with a PLC. The benefit of this solution is that the time needed to obtain a final plank cutting scheme was reduced to ca. 15 ms.
