Program table corresponding to the diagram (with setting “Step”):
set-point
[ °C]
TEMP
[hh.mm]
You can now enter the values of such a program table to the RD3 program controller (chap. 8.2).
8.1.3 General notes on programming temperature transitions
When exceeding the tolerance limits set in the user level (chap. 10), the program is interrupted until the
actual temperature value returns to within the tolerance range. During this program interruption, the LED
(7d) flashes. Therefore, the duration of the program may be extended due to the programming of
tolerances
The programming is saved 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.
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, press down button X/W for 5 sec to access the program editor. 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, we recommend entering the values of the program course into a
table (template in chap. 8.3).
Example of program table (with default setting “Ramp”):
[ °C]
[hh.mm]
You can now enter the values of the program table to one of the program places of the RD3 program
controller.
