5.2 Operating modes
The 2-channel program controller MB1 operates in 3 modes:
Idle Mode The controller is not functional, i.e., there is no heating or refrigeration
and no humidification or dehumidification. The fan turns at a 50% rate.
Manual Mode
(Fixed value operation)
(HAND)
The controller operates as a fixed-point control, i.e., set-points for
temperature and humidity can be defined, which are then maintained
(chap. 8).
Program Mode (AUTO)
An entered temperature and humidity program is run (chap. 9).
The program controller MB1 permits programming temperature and humidity cycles.
The controller offers 25 program memory positions with 100 program sections each. The total number of
program sections of all programs is limited to 500.
Programming can be done directly through the keypad of the controller or graphically through the software
APT-COM™ 3 DataControlSystem (option, chap. 15.1) 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 tempera-
ture and humidity to the last entered set-points, while in Program Mode (AUTO) it regulates temperature
and humidity to their set-points that were reached during the program operation. The power failure is not-
ed 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 (3) to position I. The pilot lamp shows the unit is ready for operation.
Observe a delay time of about 30s between turning Off and On again. Otherwise an initializa-
tion 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 temperature and
humidity to the last entered set-points, and in Program Mode (AUTO) it regulates temperature and humidi-
ty to their set-points reached during the previous program operation.
