Digital controller: how to programm it?

Click For Summary

Discussion Overview

The discussion revolves around programming a Honeywell-Mellen UDC 3200 digital controller to achieve a specific heating rate for a process reaching 1000°C. Participants are exploring the settings and parameters that influence the heating ramp rate.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant shares their current programming settings and expresses concern about the heating rate being too fast.
  • Another participant suggests that the issue may not be related to programming but rather to the constraints of the heating element itself.
  • A third participant inquires whether the controller has a variable for ramp rate, indicating that such a feature could be relevant to the problem at hand.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on whether the problem lies in the programming of the controller or the characteristics of the heating element. Multiple viewpoints are presented regarding the source of the issue.

Contextual Notes

There is uncertainty regarding the specific parameters and settings available on the UDC 3200 controller, as well as the influence of the heating element's constraints on the heating rate.

Hi!

I have to use a Honeywell-Mellen controller UDC 3200.
To heat up to 1000°C with 5°/C min.
I was programming as follwing:
SRAMP
Time:250
EU/HR: 8500
GAIN: 60.0

but is is still fast heating ?
Have you any idea how to do it?

Thank you in advance!

Read the datasheet?

Your question doesn't look like programming problem.
It looks more like you are asking about heating element constraints.
 
I am asking how to set the programm because I have the problem that is too fast heating.
I do not know what is wrong.
 
1000C, eh? Hot dog! On our ovens, the ramp rate is set with the RATE variable. Does your machine have something similar?
