The values of such a program table can now be entered to the RD3 program controller (chap. 8.2).
8.1.3 General advice for the 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 is again situated in 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 conserved even in case of power failure or after turning off the chamber.
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.
Inactivate 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 hitting button X/W for 5 sec. Here the set-points
are entered one after the other in all program sections of a selected program.
Two programs with up to 10 sections each or one program with up to 20 sections can be entered (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).
