ROPEX TCR Correction Setup:

TCR Correction

(example: RES-5011 + Ropex-Visual) … Note: Ropex-Visual authorize passwords (ref. documentation / ropex3)

The following procedure assumes that the AutoCAL Ambient Temperature Procedure is complete, and the TC is still installed.

  • Set controller Temp Range/Temp Coefficient rotary switch to (9) PC Configuration

  • Using Ropex-Visual, set controller PPM to 1000 (this is an initial starting value)

  • Via machine HMI, set heat-seal temperature to 120°C

  • Via machine HMI, set heat-seal time to 5 seconds

  • Via machine HMI, set cooling time to 0 seconds

  • Run one cycle … note maximum (TC) thermocouple value

  • Using Ropex TCR Calculation Tool, calculate new (TCR) Temperature Coefficient of Resistance value

  • Using Ropex-Visual, enter new controller PPM value (value from TCR-Cal-Tool)

  • Run verification cycle … HMI displayed temperature should = TC displayed temperature

Heat-Seal Band Verification

The above steps enable a technician to change a heat-seal band and verify the heat-seal band will deliver the same result as the previous band installed. It is critical a Protocol is developed, and the steps are followed closely, to ensure an accurate result.

  • When verifying double sided heat, the verification temperature should only be taken without film/material loaded in the machine. (The introduction of film would alter the TC reading. If the film is placed on the TC, this will act as an insulation layer and the TC values will be lower than those previously viewed. If the film is placed to the side of the TC, this can produce an air gap that will cause the TC to display a much higher temperature as the energy is not being uniformly transferred from the heat-seal band).


  • When the AutoCAL function is executed with equipment poised in a controlled, repeatable, and reproducible manner, the result is a datum/base point that will then allow for the controller TCR value to be set. The entered TCR value will then provide a repeatable and reproducible known heat-seal band temperature.

  • These steps enable a technician to change a heat-seal band and verify the heat-seal band is operating per the original (EOQ) Equipment Operation Qualification.

  • In addition to heat-seal band changes, the ability to quickly verify the equipment operation is critical when the Process Engineer is trying to resolve an issue.

  • Example: Is an issue due to a change to the equipment setup (different thickness of Cover-Strip over the heat-seal band), or a change of the product material (different film). The failure, or change, can be detected by verifying the EOQ TC temperature. If the original EOQ TC value is obtained (without material/film), the heat-seal band Cover-Strip and layup is correct, and it is likely a change in the product material (film gauge or material composition) that is causing the issue.
