Programming can be done directly through the keypad of the controller or graphically through the soft-
ware APT-COM™ 3 DataControlSystem (option, chap. 11.1) specially developed by BINDER.
5.3 Performance after power failures
After the power returns, the unit continues to function in the original operating mode it was in previously
before an actual power failure had occurred. In Manual Mode (HAND), the controller regulates the tem-
perature 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 unit
Set the main power switch (2) to position I. The pilot lamp shows the unit 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 unit by pressing any button. When turned on, the unit functions in the operat-
ing mode entered before turning off. In Manual Mode (HAND), the controller regulates the temperature to
the last entered set-point, and in Program Mode (AUTO) it regulates the temperature to the set-points
reached during previous program operation.

mum speed).
If the unit is fully loaded, the specified heating up and cooling down times may vary according
to the load.
