March 18, 2014 in REFLOW SOLDERING
We have added a new feature to our PC program v1.2, user sequences.
This means that from now on you can create your own sequences of phases and save them in the hard-drive of your computer to run them later. This is handy if you want to do non standard soldering recipes or to use your controller as a temperature controller for anything different from a soldering controller.
Here it is our new sequence editor:
So in the combo box “Phase type” you can select the type of phase you want to add, you can select from:
- Time limited and temperature controlled PID:
This type of phase will start the % PID regulator so it will try to arrive as fast as possible the target temperature in the “Temperature” Textbox. Once reached the temperature will be maintained for the “Time” in seconds stated in the Textbox. The “Max Time” Texbox will define how much time in seconds we will try to arrive to the PID target temperature, if the temperature is not reached in this time the sequence will be stopped and an alarm will be issued.
- Time limited PWM:
This type of phase will trigger the fix % PWM rate in the “PWM rate” Texbox. This PWM will be maintained for the “Time” Texbox seconds. The sequence will be aborted and an alarm issued if we go over the “Max Temp” Texbox temperature.
- Temperature limited PWM:
This type of phase will trigger the fix % PWM rate in the “PWM rate” Texbox. This PWM will be maintained until the “Temperature” Texbox temperature is reached. The sequence will be aborted and an alarm issued if we go over the “Max Time” Texbox time in seconds before reaching the target temperature.
- Time limited Wait:
This will just stop all during the time in seconds in the “Time” Textbox .
This will restart the sequence automatically. Use this function with caution as it will run in loop the sequence until manually stopped. No parameters for this phase.
- Time limited PWM in Out 2 (WORKS ONLY IN CONTROLLERS WITH FIRMWARE OVER v.28):
This type of phase will trigger the fix % PWM rate in the “PWM rate” Texbox, but this time only in the Output 2 of the controller. This PWM will be maintained for the “Time” Texbox seconds.
You can add phase by phase using the “Add Phase” button, this phase will be added to your sequence. You can see a summary of your complete sequence in the “Sequence Summary” Texbox. You can also delete a phase in the sequence by typing the number of the phase in the Texbox next to the “Delete Phase” button and hitting the delete button.
Once you have defined your sequence you can save it with the “Save Sequence” button, it will be stored in a txt file and you can open it later using the “Open Sequence” button.
To Start a sequence just hit the “START SEQUENCE” button, the sequence will be executed and once finished it will be stopped automatically. If you want to stop it before the end you can use the “STOP SEQUENCE” button.
Another new feature of this version of the program is on the PWM tab. Now you can also start a constant PWM test in the second output of the controller. Just type the PWM rate in the CYCLE Textbox and hit Start in the PWM2 “Start” button. Unfortunately this feature will only work in controllers with firmwares over v.28.
Hope you like it.
