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 50% rate.
When manually switching the fluorescent tubes, radiation exposition of
the samples and light integration are possible.
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). For the function Light Quantum Control, target dose values
of VIS and UVA can be entered. When they are reached, the fluores-
cent tubes are automatically turned off, and a message is displayed
(chap. 9).
Program Mode (AUTO)
An entered temperature and humidity program is run (chap. 10).
When manually switching the fluorescent tubes light integration is
possible.
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 soft-
ware APT-COM™ 3 DataControlSystem (option, chap. 17.1) specially developed by BINDER.

Performance after power failures
After the power returns, the unit continues operating in the operating mode actual before power failure. In
Manual Mode (HAND), the controller regulates temperature and humidity to the last entered set-points,
while in Program Mode (AUTO) it regulates temperature and humidity to their set-points actually reached
during program operation. The power failure is noted in the event list (chap. 6.2) No error message is
displayed indicating that a power failure has taken place. Exposition with radiation is continued as had
been set manually or automatically before power failure. Integration of the light values continues with the
dose values reached before power failure.
