5.2 Operating modes
The MB1 2-channel program controller 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 the fluorescent tubes are turned on manually, radiation exposi-
tion 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 automatically turn off, and a message is displayed (chap.
9).
Program Mode (AUTO) An entered temperature and humidity program is run (chap. 10).
When the fluorescent tubes are turned on manually, light integration is
possible.
The MB1 program controller 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.
5.3 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 in the
same was as it had been set manually or automatically before power failure. Integration of the light values
continues with the dose values reached before power failure.
