Programming can be done directly through the keypad of the controller or graphically through the APT-
COM™ 4 Multi Management Software (option, chap. 11.1) specially developed by BINDER.
5.3 Performance after power failures
After the power returns, the chamber continues to function in the original operating mode it was in previ-
ously before an actual power failure had occurred. In Manual Mode (HAND), the controller regulates the
temperature to the last entered set-points, while in Program Mode (AUTO) it regulates the temperature to
its set-point that was reached during the program operation. The power failure is noted in the event list
(chap. 6.2) however, no error message is displayed indicating that a power failure has taken place.
5.4 Turning on the chamber
Set the main power switch (2) to position I. The pilot lamp shows the chamber is ready for operation.
Observe a delay time of approx. 30s between turning Off and On again. Otherwise an initiali-
zation problem may occur (display showing e.g. “–1999”).
Note that the chamber is in stand-by mode when the main power switch is in position I and the controller
display is dark. Turn on the chamber by pressing any button. When turned on, the chamber functions in
the operating mode entered before turning off. In Manual Mode (HAND), the controller regulates the tem-
perature to the last entered set-point, and in Program Mode (AUTO) it regulates the temperature to the
set-points reached during previous program operation.

Heating up time
Average heating up time approx. 5 °C/min (the air flap closed and the fan set to maximum speed).
Cooling down time
Average cooling down time approx. 0.2 °C/min to 1.5 °C/min (the air flap open and the fan set to maxi-
mum speed).
If the chamber is fully loaded, the specified heating up and cooling down times may vary ac-
cording to the load.
