Section 4 THEORY OF OPERATION This section describes the Plum A+3 theory of operation. The theory of operation details the general description, electronic subsystem overview, printed wiring assemblies, remote mounted peripherals, and mechanical overview of the infusion system. 4.
PAGE 28
SECTION 4 THEORY OF OPERATION 4.2 ELECTRONIC SUBSYSTEM OVERVIEW This section describes the function and electronic circuitry of the following three main subsystems in the infusion system: CPU subsystem, power supply subsystem, and mechanism subsystem (see Figure 4-1).  Note: An asterisk (*) denotes an active low or negative true logic signal.
PAGE 29
4.2 ELECTRONIC SUBSYSTEM OVERVIEW 4.2.1 CPU SUBSYSTEM The CPU subsystem contains the main microcontroller that is responsible for controlling the display/keyboard interface, external communications interfaces, barcode reader (BCR) interface, and system management.
PAGE 30
SECTION 4 THEORY OF OPERATION 4.2.1.3 PROGRAMMABLE READ-ONLY MEMORY The CPU subsystem has two 512 K x 8 bit programmable read-only memory (PROM) memory devices that provide a total of 1024 KB. The PROM space is expandable up to 2 MB. The PROM memory devices operate off the 3.3 VDC supply. The CPU chip-select 0 pin (CS0*), is connected to the PROM chip-enable (CE*) pin (signal CSROM*). This special chip-select signal can support bootstrap operation after reset.
PAGE 31
4.2 ELECTRONIC SUBSYSTEM OVERVIEW 4.2.1.7 LCD BACKLIGHT CONTROL The LCD panel is backlit by a cold cathode fluorescent tube (CCFT) lamp. The CCFT lamp requires 300 Vrms to operate; a current controlled DC-to-AC voltage inverter circuit is used to deliver a current regulated sine wave to the lamp. A switching regulator regulates the CCFT current by monitoring feedback pin 3, and varies its output duty cycle to drive a DC/AC inverter.
PAGE 32
SECTION 4 THEORY OF OPERATION 4.2.1.10 VOLTAGE MONITOR WATCHDOG TIMER It is important to protect the system during power transitions, and the CPU is reset after the VCC power supply is applied. The microprocessor supervisory circuit generates an automatic reset output during power up, power down, or brownout conditions. When the VCC falls below the reset threshold voltage of 2.

PAGE 34
SECTION 4 THEORY OF OPERATION 4.2.1.12 DIGITAL-TO-ANALOG CONVERTER The dual 8 bit digital-to-analog converter (DAC) generates two analog signals to control the phase A and phase B motor coil currents. The interface between the DAC device and the CPU is the 8 bit data bus that is connected to DATA15:8. All the control signals for this DAC are generated by FPGA logic devices. Buffer amplifier/ground compensation circuits condition the DAC outputs. 4.2.1.
PAGE 35
4.2 ELECTRONIC SUBSYSTEM OVERVIEW 4.2.1.17 NURSE CALL INTERFACE A nurse call relay switch on the peripheral interface PWA indicates alarm conditions to a remote operator. A memory-mapped output signal (NURSE) activates the relay during alarm conditions. The relay has both normally-open and normally-closed contacts. A jumper on the peripheral interface board selects the contact type. The factory setting is normally-open. 4.2.1.18 AUDIBLE INDICATORS There are two audible indicators on the CPU subsystem.
PAGE 36
SECTION 4 THEORY OF OPERATION 4.2.1.20 DATAPORT INTERFACE The CPU communicates with an external computer by way of a DataPort interface. The DataPort interface provides for remote monitoring of up to four infusers using a host computer with a modified RS-232-D serial interface. Infusers are either connected directly to the host or in a daisy chain configuration using junction boxes that provide a 5 bit hard ID via DIP switches on the junction box.

4.2 ELECTRONIC SUBSYSTEM OVERVIEW 4.2.2 POWER SUPPLY SUBSYSTEM The power supply subsystem provides DC power to system circuits and interface software controlled power and battery management.
PAGE 40
SECTION 4 THEORY OF OPERATION 4.2.2.1.3 Current Limit Loop The current limit loop is activated when the primary current, sensed by R71, exceeds 3 A. Resistor R70 and capacitor C46 filter the voltage across R71 and feed it back to the current sense input (1.5 VDC threshold) of U12. The duty cycle of U12 is reduced until the excessive load is removed. 4.2.2.2 MAIN REGULATOR FAULT DETECTION If the switching regulator’s main loop fails, the secondary voltage limit loop takes over.
PAGE 41
4.2 ELECTRONIC SUBSYSTEM OVERVIEW The infuser is activated when the [ON/OFF] key is pressed or the AC line is plugged in. The [ON/OFF] key activates the STRTUP signal, triggering a three second one-shot circuit that will temporarily turn the system power on. This three second one-shot period allows the CPU enough time to power up, initialize, and turn on the PWRHLD signal. The CPU monitors the STRTUP signal, via interrupt, to signal a user request for turning off the infuser.
PAGE 42
SECTION 4 THEORY OF OPERATION 4.2.2.8 BATTERY CHARGER The software battery management algorithm controls the battery charger. The charging scheme is a current limit/two stage voltage limit charger. The charge current is limited to 1.3 A and the voltage is limited to either 6.9 VDC or 7.5 VDC. The source of the charge current is power MOSFET transistor Q7 operating in the linear mode.
PAGE 43
4.2 ELECTRONIC SUBSYSTEM OVERVIEW 4.2.3.1.1 Stepper Motors Each motor is named by its function, as follows: - Plunger motor for driving the plunger screw - I/O valve motor for moving the input-output valve pins - L/S valve motor for moving the line select valve pins A and B All three motors are four phase stepper types. One electrical revolution is accomplished after four motor steps (phases) are completed. The step-angle (the number of steps per shaft revolution) resolutions are 3.
PAGE 44
SECTION 4 THEORY OF OPERATION 4.2.3.2 MOTOR POSITION SENSORS Motor position is estimated by counting the motor steps, relative to a position reference. Optical switches and flags serve as position references that are used to find the motor home positions and to verify proper motion. Flag positions are anticipated by software.
PAGE 45
4.2 ELECTRONIC SUBSYSTEM OVERVIEW 4.2.3.4 AIR SENSORS The mechanism subsystem includes two air sensors, used to detect air passage into (proximal) or out of (distal) the cassette. Both sensors are piezoelectric crystal transmitter receiver pairs. Liquid between the transmitter and receiver will conduct the ultrasonic signal, while air will not (see Figure 4-5). XTL TX VSO VCO/PLL CPU Figure 4-5. G_RX G_TX OUTPUT AMP A/D XTL RX PEAK DETECTOR Air Sensor Block Diagram 4.2.3.4.
PAGE 46
SECTION 4 THEORY OF OPERATION 4.2.3.4.2 Receiver Circuitry When the cassette’s test port is filled with fluid, the transmitted signal will be coupled to an identical piezoelectric crystal, where it is amplified and detected by the receiver circuitry. The receiver circuitry consists of an amplifier, a peak detector, and an adjustable gain buffer stage. There is a separate, symmetrical receiver circuit for each channel (proximal and distal).

PRESSURE SIGNAL OUTPUT (TO CPU) Pressure Sensor Excitation and Amplifier Block Diagram 4.2.3.5.1 Bridge Excitation Supply The bridge excitation voltage is 3.75 VDC, and is derived from the 2.5 VDC reference signal (V2_5), gained 1.5 times by an amplifier.
PAGE 48
SECTION 4 THEORY OF OPERATION 4.2.3.6 PRESSURE SENSOR CALIBRATION Pressure sensors are calibrated for offset and gain during mechanism calibration. A trimming potentiometer is used to adjust the initial, zero pressure offset. The proximal and distal pressure sensors have independent offset adjustments. The final system gain (cassette pressure to corrected amplifier output) is adjusted in software.

4.4 REMOTE MOUNTED PERIPHERALS 4.4 REMOTE MOUNTED PERIPHERALS Remote mounted peripherals include the LCD, sealed lead acid battery, and barcode reader (BCR) wand. 4.4.1 LCD The infuser uses a graphic LCD module with a CCFT. The CCFT provides a backlight source for the LCD. The LCD requires a nominal -16 VDC supply for contrast control that is controlled by the CPU.
PAGE 54
SECTION 4 THEORY OF OPERATION 4.5.1 CASSETTE The cassette (see Figure 4-7 and Figure 4-8) operates on a fluid displacement principle to volumetrically deliver fluid. See the system operating manual for a description of the major cassette functions. The pumping cycle begins when the outlet valve is opened and the inlet valve is closed. The plunger extends to deflect the cassette diaphragm and expel fluid.
