  • Page 14 2.1.1.2.1.3 Booster module BOOST = 0 The motor is powered via VBAT voltage. BOOST = 1 Booster function activated, the motor is powered at 12 Volts. L2 reactor, D18 diode, C15 capacitor and T8 transistor assembly allows a voltage of 12 V +/- 2 volts to be obtained from VBAT.
  • Page 15 2.1.1.3. Analog output module The analog output module is built around a 10 bit, 5 channel analog/digital converter (MC 145053 U17) with an SPI bus. The following SPI CLK, SI, SO, CSADC bus signals are available on connector J2: In addition the component generates an end of conversion signal (EOC). The CDANA signal, which is active when set to 1, controls the transistor T14 IRFD 9120 which digitally drives VREF.
  • Page 16 2.1.1.3.3. Driving bloc position sensor The absolute position of the driving bloc is obtained by a potentiometric sensor driven by a movement of the driving bloc. The transfer function of the sensor can be characterised by calibration in two known positions. The sensor is powered by a pulsated voltage.
  • Page 17 J8 is the ribbon cable linking the occlusion, disengagement and position sensors located on the syringe pump driver. The CDOPT2 and SOPT2 signals are emitted by the CPU board and available on J2 connector. The opto diode is powered by pulsated voltage in order to save energy. 2.1.1.5.

  • Page 23 2.2.1.2.2. Watch-dog The WATCHDOG circuit comprises the following elements: U10, U11, C12, D2, D1, R4, C11. When powered up the capacitor C12 is charged by the U10 circuit, via diode D1. The charge is maintained at a threshold of over 1.5 V during operation. The software writes, every 1 ms.This writing generates a 5V/1µs impulse on the U7.10 output, which re- charges the capacitor C12 via a high pass peak detector circuit made up C8, D3, D2.
  • Page 24 2.2.1.4. SPI bus EEPROM The SPI bus is synchronous series communication bus using various peripheral circuits. The SPI bus is driven by the 80C32 ports. The Injectomat 2000 Anästhesie syringe pump has 2 peripheral devices on the SPI bus: The EEPROM 2 Ko 24C16 U12 located on the CPU board. The MC 145053 analog/digital converter located on the motor board.
