Jouan B4i - Microprocessor + Power Pcb

B4i-M
2 - 9
ZONE 1 :
This zone includes the microprocessor, the EPROM containing the software and the non-volatile RAM
containing the program parameters. The set of components in this zone is at the potential of the
microprocessor : 5 VDC.
ZONE 2 :
This zone ensures the conformity of the signal type coming from the different detectors before their arrival
at the microcontroller via opto couplers.
It also monitors the lid lock control and refrigeration group commands.
The power supply for this zone is 12 VDC.
The different signals coming to this zone are :
- Bowl temperature.
- Signal coming from the imbalance sensor
- Tacho signal
- Lid position signal
- The motor overtemperature and the lid lock solenoid control.
2.4.2. MICROPROCESSOR + POWER PCB
On the microprocessor + power pcb, 3 distinct zones can be identified, whose functions are described
below. Each zone has its own independent power supply.
