The values of such a program table can now be entered to the RD3 program controller (chap. 8.2).
8.1.3 General notes on programming of temperature transitions
If the tolerance limits set in the user level (chap. 10) are exceeded, the program is halted until the actual
temperature value returns to within the tolerance range. During this program interruption, the LED (3d)
flashes. Therefore, the duration of the program might be extended due to the programming of tolerances
Programming is saved even in case of a power failure or after turning off the chamber.
The cooling power decreases when the fan speed is reduced to 20% or below.
After program rundown the controller returns to Fixed value operation showing Normal Display and
equilibrates to the temperature value previously entered in fixed value entry mode.
Before starting the program, check the set-point value entered in Fixed value entry mode.
After program rundown temperature will equilibrate to this value.
Deactivate the week program timer (factory setting, setting in the user level, chap. 10) before
starting a program.
8.2 Set-point entry for program operation
From Normal Display the program editor is accessed by pressing button X/W for 5 sec. Then enter the
set-points one after the other in all program sections of a selected program.
You can enter two programs with up to 10 sections each or one program with up to 20 sections (setting in
the user level, chap. 10).
In order to avoid incorrect programming the values of the program course should be entered into a table
(template in chap. 8.3).
