2 ELECTRONIC BOARD
2.1. MOTOR POWER SUPPLY AND CONTROL BOARD
2.1.1. Functional description
In order to simplify wiring the motor power supply control board concentrates 6 functional modules,
which may be described separately:
q power supply module,
q motor control module,
q
analog output module,
q
disengage and anti-siphon opto switch module,
q microswitch input module,
q optional nurse call and RS232 interface module.
2.1.1.1. Power supply module
The power supply module consists of a cut-out power unit. It supplies all electronic components and
charges a 1,1 Ah / 1,2 Ah backup battery from a mains voltage input or a 12/15 volt DC power source. It
generates the + 5V and Vbat voltage required by the electronic components. Finally it comprises an
ON/OFF switch controlling the various power supplies.
2.1.1.1.1. Mains power supply
The mains power supply generates a DC voltage ranging from 10 and 16 volts for a maximum current of
1,2 A.
