G1 Control

Product catalog summary

Program Overview:
This document outlines a sample program for controlling temperature and humidity over a series of steps. The program is designed to be executed in a controlled environment chamber and involves setting initial conditions, executing loops, and utilizing wait functions.

Specifications:

Timebase: The program operates on an hourly timebase.
Initial Conditions: Start at 20°C and 60% relative humidity.
Program Number: Save as Prog.No. 12.

Procedures:

Initial Setup: Define start values at 20°C and 60% r.H.
Temperature and Humidity Changes: Gradually change temperature and humidity according to specified durations and values.
Loop Execution: Repeat specified steps three times between defined start (SA) and end (SE) loop markers.
Wait Function: Activate wait function for temperature with a tolerance of ±1 Kelvin.

Key Steps:

Remain at 20°C for 1 hour.
Increase temperature to 80°C over 2 hours and maintain for 2 hours.
Switch off humidity regulation when temperature drops below +10°C.
Decrease temperature to -40°C over 1 hour and maintain for 2 hours.
Return to 20°C over 1 hour and switch on humidity regulation.

Recommendations:

Always set a starting value to avoid using previous set values.
Consider using CID-Software for easier program generation.

Programming Instructions:

Enter Edit-Mode to modify the program.
Set start values for temperature and humidity.
Define loop parameters and inactive lines for program control.
Save the program after completing all steps.

Comments:

The program should be edited without switching off the chamber.
Ensure the existing program is erased before saving a new one under the same program number.

Catalog excerpts

Comments: - The timebase of the programme is hours. This is because in the example only programmesteps with whole hours are used. - Always set a starting value for the programme (first line with time t=0). In other case the controller starts the programme with the last used setvalues - We suggest to create the testcycles via CID-Software, because programme generation with CID is very easy. The programme should be saved as Prog.No. 12. It’s not neccessary to switch off the chamber to edit a new programme +/- Temp if there is a programme saved under Prog.No 12, the number of used Lines of this...
