Clamping System

4.3.1

Removing and Installing the Clamp

The clamp is mounted to the bottom of the equipment by means of 3 screws on its base. The cables attached to the connector in the illustration are responsible for controlling the clamp’s activation. During replacement, be aware that the chamfered surface on the base of the clamp faces the transformer. This guarantees the correct positioning of the clamp.

4.3.2

Operational Test of the Clamp Necessary equipment: • 1 x 20 ml disposable syringe, • 1 pressure gauge with a scale of up to 2 Bar, Opening and Closing. Carry out the “INITIAL TEST” procedures in accordance with item 3.4 in this manual.

Closing Effectiveness.

Setup a system as shown in the figure on the side.

Power the equipment on. Place the clamp on a section of the tube immediately after the pressure gauge. Start a new donation procedure. The clamp should close when the display shows “PUNCTURE AND ENTER”. When this happens exert pressure on the syringe until the pressure gauge gives a reading of 1 BAR (kgf/cm²). To check if the clamp is “sealing” the pipe completely insert the end of the pipe into a container with water, and at the moment that the syringe is pressed there must be no bubbles inside the container.

To eliminate the probability of a reading error from the scanner it is recommended that barcodes that have a checksum be used. The checksum is a digit on the barcode; this digit is a function of the value of the code. Thus there is a relationship between the value of the checksum and the barcode, and if there is a failure in the reading then the scanner will not transmit the value to the mixer, repeating the reading until there is a correct relationship. E.g. of barcodes that have a checksum: CODE 128, CODE ISBT 128, CODABAR.

The Memory Batteries on the Equipment To retain all of the collection data during the time that the HemoLight Plus remains disconnected from mains power and without its primary battery connected, it is necessary for internal memory batteries. The memory power supply unit on the HemoLight Plus is made up of 3 AA alkaline batteries of 1.5V each, set in a compartment on the bottom of the HemoLight Plus. It is recommended that the batteries be removed from the equipment under long periods of inactivity. Under these conditions the equipment must be reconfigured when it returns to normal usage.

When the memory batteries on the HemoLight Plus become weak the display on the equipment will display the following message:

MEMO BATTERY LOW These must then be changed immediately with the equipment still powered on so as to retain its data. I The batteries life expectancy may vary and is influenced by a number of factors, some of these are: Battery type (alkaline or common). Temperature. Length of time that the HemoLight Plus remains powered on. Whilst the HemoLight Plus remains powered on, either to mains or to the primary battery, the batteries will not be used, the batteries will only come into operation when the equipment is completely powered off. Therefore the longer that the HemoLight Plus remains powered on the longer the batteries will last. It is possible that after a long period of inactivity, when powered on, the HemoLight Plus will indicate that the batteries must be changed.

Primary Battery Circuit The HemoLight Plus is able to operate with power coming from a rechargeable lead-acid battery. When fully charged it is able to work under standalone for approximately 3 hours of effective collecting (approximately 15 complete procedures). The battery compartment is accessible from the side of the equipment. There is only one way to connect and it is impossible to invert the polarity. If a battery is connected to the equipment and the equipment itself is connected to a mains outlet with the ON / OFF switch in the “ON” position, then the battery will be charged. The charger on the HemoLight Plus takes around 10 hours to fully charge. The primary battery is connected in parallel to bridge rectifier BR1. Diodes D11, D87 and D8 prevent the battery supplying current to source or even to its charging circuit.

Charge the battery before using it for the first time and then immediately charge it again after use. Never fully discharge the battery. Remove it from the compartment whenever the equipment is to remain inactive for a long period of time. (The equipment on standby continues to consume battery power). Do not continue to use the equipment if it indicates that battery charge level is low. The HemoLight Plus functions will be compromised. The batteries have a limit to their charge/discharge cycles. If they do not fully recover their capacity, then their working life is at an end. In this instance it must be replaced with a new one. Recharge the battery only with the HemoLight Plus charger or charges specifically for this purpose. Do not try to disassemble the battery. The sulfuric acid may cause injury to the skin and other parts of the body. Do not incinerate. The discarded batteries must be recycled. Look for information with the local refuse collection services in your town to know how to proceed.

The charging circuit is built with a L200C (U17) regulator mounted so as to supply a controlled voltage and current to the battery when it is being charged. The regulator limits the maximum charging voltage to 14.5 Volts and limits the circulating current to 200mA. The switching between the battery and mains power is done automatically. In the absence of an external power source the supply of the circuits will be taken over by the battery. Whenever the equipment is being supplied by the battery, the yellow indicator LED 4 will light up. A comparator circuit is built with an operational amplifier (U16 port D). In the absence of an external power source the comparator’s output is set to zero volt, guaranteeing that the yellow LED lights up. LED LD1 on the indicators board is a bicolor LED which turns green when the battery is being charged and red when the battery is discharged. The comparator built with U15 monitors the current circulating through the charging circuit. If there is a current circulating, pin 6 of U15 will be high. Under this condition the bicolor LED will be green indicating that the battery is being charged. If the battery is removed or if the mains power is removed then the output of U15 (pin 6) will be low thus preventing LD1 turning green. The battery’s charging condition is digitally checked from an A/D converter. The input to the A/D converter (pin 39 U2) is connected to resistor R40. The voltage across R40 represents 1/3 of the battery’s voltage. Whenever the battery’s voltage is less than the critical (11.7 V) value the processor will notify the

operator that the battery must be changed, by presenting a message on the display. Pin 10 on U2 will go high causing LD1 to turn red. The current version of the CPU board is compatible with the previous display board version, but to be able to use it, it will be necessary to remove jumper JP4, and use the auxiliary display Board Cable (234985018). NOTE: The ON / OFF switch does not power the equipment off when there is a battery connected.

The disposed batteries must be recycled. Look for information from your local refuse collection services to see how to proceed

6.3.4

Standby Circuit With the intuition of increasing the standalone time of the HemoLight Plus, it will automatically enter the “Standby” mode after being idle* for 20 seconds. This process is controlled by the CPU that carries out the powering off process through a relay (K4) with reversible contacts and a double holding coil, the equipment’s general relay. This relay does not need to remain energized after switching. Each of its coils must be energized individually when necessary. When the SET coil receives a voltage pulse the relay closes a contact that will be opened again when the RESET coil receives a pulse. The CPU detects the absence of an external power source through the resistor bridge made up of R30, R41 and R36. When this happens and if the equipment is idle then the controlling software triggers a timer. If the trigger reaches the programmed time, then processor U2, Tiny Tiger, will signal the relay with a high from its pin 11 (Standby). This signal is transferred via operational amplifier U16 PIN 8, polarizing transistor Q4 activating the RESET coil on the relay. The HemoLight Plus is then powered off at this point. There are two possibilities for powering the equipment on again. The first, via reconnection to mains power, which will switch the general relay through transistor Q3. The second possibility is by pressing the RESET switch on the equipment, which will switch the general relay through transistor Q2.

*The HemoLight Plus is considered idle only when the display is alternating between date and time.

Micro-controlled CPU The HemoLight Plus is a micro-controlled homogenizer. Its operation is managed through software. All of the CPU’s integrated circuits use TTL technology. Power Supply = 5Vcc (U10). The CPU is made up of 4 different circuits: • • •

Keypad and Display Matrix Driving Peripherals Serial Interface

•

Analogue Inputs 6.3.5.1

Controlling the Keypad and Display Matrix Pins 1, 2, 3, 4, 5, 6, 7, 8, 20, 31, 32, and 33 of the Tiny Tiger micro-controller are used to control the display and keyboard matrix of the HemoLight Plus. Tiny Tiger Pin Outs 1 to 8 20 31 32 33 14 15 16

Buzzer

To make up the keypad matrix three integrated circuits are used: Demux TTL Decoder 74LS138 (U5), D Octal TTL Flip Flop 74LS373 (U1) and Octal TTL Transceiver 74LS245 (U7). Whenever a key is pressed a line is shorted out with a column of the keypad matrix generating a binary code interpreted by the Tiny Tiger data bus. The keypad sound is generated by pin 20 of the Tiny Tiger. This pin is always high (5Vcc) keeping transistor Q1 constantly saturated. When the keypad sound is enabled and a key is pressed then pin 20 goes low 0 Volt, causing the transistor to enter into the cut off region and activating the buzzer. The display’s contrast is adjusted by potentiometer R5. 6.3.5.2

Driving the Peripherals The following are considered as peripherals, oscillating base circuit, clamp and alarms. Pin 14 when high (5Vcc) starts the tray movement. Pin 15 when high opens the clamp, and analogically, the same pin when low closes the clamp. Pins 16 and 17 when high respectively enable the red LED alarm and buzzer. The red LED and buzzer are connected to the logical inverter 74LS04 (U4) output ports. This configuration allows for a

slightly higher current level than which is supplied by the microcontroller’s pin. The Oscillating Tray and Clamp circuits will be detailed later 6.3.5.3

RS232 Serial Interface The HemoLight Plus has two serial ports. One of them is used by the Scanner to obtain the data from reading a barcode. The other is used to exchange data with a PC (RS485) when the HemoData NET network module is installed.

Tiny Tiger Pin Outs 23 24 26 27 28

Function RS485 TX RS485 RX Scanner TX Scanner LX RS485 Control Pin

The scanner communicates with the HemoLight Plus at a transmission rate of 2400 Baud. Pins 26 and 27 of the Tiny Tiger are connected to a DC-DC converter Max232 (U3). This configuration allows for data with different logic levels other than 5Vcc to be read without the serial port being damaged. (A direct connection to a PC is possible). Pins 23, 24 and 28 of the Tiny Tiger module are connected to a RS485 Transceiver 75176 (U6). The output of the 75176 is made up of a differential pair. In configurations of this type it is possible to build a network where all of the equipment that is powered on is identified. Pin 28 of the Tiny Tiger defines the communications direction: High (5Vcc) – HemoLight Plus transmitting Low (0Vcc) – HemoLight Plus receiving data For it to work on the network it is necessary to implement a HemoData NET module. The HemoData NET module is made up of a PC (MASTER) and up to 32 HemoLight Plus (SLAVES) all of them connected to the same differential pair (network). When the network is inactive all of the HemoLight Plus will be in a listening condition. (Pin 28 low). Once the PC sends a piece of information, the addressed HemoLight Plus enters into a transmission condition (Pin 28 high). The network protocol is controlled via software. The initial information is sent as 9 Bits and always comes from the PC. Connector RJ11 – 2 active routes – RS485 Interface Transmission rate 38400 Baud 6.3.5.4

I2C Serial Interface The HemoLight Plus records the data on the Smart Card Memory through the socket located on the CPU board. Communications between the two is done through the I2C protocol, in which the HemoLight Plus is the master and the Smart Card Memory is the slave. Pin 18 of the Tiny Tiger is the SDA data pin and pin 13 is the SCL clock.

For a piece of data to be recorded it will be necessary for the master to send a start signal, after this signal has been sent the address will follow, and if the data is recorded or read, the data will follow in sequence. Whenever a piece of data is recorded or read the slave confirms the operation, and then a new operation may be carried out. So that the data is valid it will be necessary for the SCL signal to be high. Pin 19 of the Tiny Tiger, when low will delete the data from the Smart Memory Card Memory. 6.3.5.5

Analogue Inputs The HemoLight Plus uses three analogue inputs to obtain external data. Analogue channel 0 is pin 37 of the Tiny Tiger. It is a 12 bit A/D converter used to obtain the amplified signal from the load cell. The voltage value across this pin will be proportional to the weight placed over the load cell. Please consult item 6.3.6 for information on this circuit. Analogue channel 1 is pin 40 of the Tiny Tiger (U1). It is also a 12 bit analogue converter used to obtain the voltage on the batteries of the HemoLight Plus. This signal is used to check the charge condition of the memory batteries. This circuit is assembled in the following manner: The voltage signal for the batteries goes through a voltage (buffer) made up of a LM324 (U18). This configuration affords impedance matching thus preventing that the memory’s batteries discharge across the A/D converter when the equipment is powered off. The input of the third logic channel is pin 39 of the Tiny Tiger (U1). This channel monitors the primary battery voltage, please consult item 6.3.3.

6.3.6

The Scale Circuit The Scale’s Circuit is made up of the load cell, amplification circuit, and A/D pre-converter filter. The load cell is of the “single point” type, 350 Ω for up to 5Kg. To increase its sensitivity this capacity is reduced by the by the amplifier circuit to 1kg. The entire scale circuit is supplied with 9Vcc (U21). The amplifier circuit is an instrumentation amplifier built up of 3 op. amps OP07 (U23, U25, U26). The converter 7660 (U24) generates a signal of - 9 V so that is able V andto- obtain 9 V). a symmetrical power supply for amplification (+ 9 The amplifier’s gain is changed through potentiometer R53. This potentiometer is used to calibrate the scale and is accessible to the equipment user. After amplification the signal passes through a high pass filter. This filter is made up of an Op Amp LM324 (U18) a capacitor (C38) and a resistor (R52). At the input to the filter there is a 5V6 Zener diode. It is used to limit the output of the amplification stage to this value.

6.3.7

The Oscillating Tray Circuit The tray movement is carried out by a 9Vcc motor. Whenever instructed by the Tiny Tiger, the optocoupler U21 will cause relay K2 to close thus placing the motor into operation. The optocoupler is used to isolate logical circuits (control) of the motor circuit.

6.3.8

The Clamp Circuit The clamp circuit basically constitutes of a 9Vcc motor and 3 logic ports, with two of them being “AND” 74LS08 gates and one "NOR” 74LS04. The operating logic is as follows: The clamp has two end of travel switches. Whenever one of them is activated a 0V signal is transmitted to one of the “AND” gates. A high signal from pin 15 (Clamp) from the Tiny Tiger causes pin 3 of the 74LS08 (U19) to go high causing the optocoupler U20 to close the relay, thus starting the clamp opening movement. When the clamp reaches its maximum opening, then the end of travel switch will be activated causing the logic of the “AND” gate to return to 0V at the output and interrupting the motor’s operation in this direction. The motor will make the closing movement when pin 15 on the Tiny Tiger is at 0V. This signal undergoes an inversion at the “NOR” 74LS04 (U4) gate causing the same effect as previously mentioned on the gate. Note that on the circuit, that for each condition, the 9Vcc voltage across the motor is inverted causing the motor to take up both rotation directions.

Memory Card Reader Circuit It may be used as a converter to use the HemoLight Plus in a network or as a Memory Smart Card reader, transferring the data from the card to the PC. The Memory Card Reader has a RS 485 to RS 232 converter and a RS 485 to I2C converter. For the data on a card to reach the PC it must first be read using the I2C protocol. The data is read using a PIC 16F628 (U6) microprocessor, through pins 8 (SCL) clock signal and pin 9 (SDA) data. Pin 8 on the PIC is connected to pin 3 of the Smart Card Memory socket and pin 9 on the PIC is connected to pin 6 of the socket. The PIC is connected to a RS 485 Transceiver 751769 (U5), pin 7 on the PIC is connected to pin 1 of the 75176 and pin 6 of the PIC is connected to pin 4 of the 75176. And so they are connected in parallel to the RS 485 network. The conversion from RS485 to RS232 takes place through Transceiver 751769 (U4), which is connected to a DC-DC Max232(U3) converter, pin 1 of the 75176 (RX) is connected to pin 11 of the MAX232 and pin 4 of the 75176 (TX) is connected to pin 9 of the MAX232. The converters are bidirectional.

HemoLight Transport Case The transport case was designed to protect the equipment from eventual shocks during transport. But, it is important to consider that even transported in this manner the HemoLight Plus is still a piece of equipment with very sensitive measuring devices, which are subject to damage if poorly handled. The mixer must also be handled with the appropriate care even when housed in the transport case. Drops and knocks must be avoided. The transport case was designed to transport the HemoLight Plus and its accessories (scanner and battery), do not transport any foreign object inside the case. If the Smart Card Memory is being used, do not close the case with the card inserted in the HemoLight Plus.

The transport case does not need preventive maintenance. To clean it, use a soft cloth dampened with 70% alcohol.

•

To open the case the four catches on the sides must be unlocked.

•

•

The lower bed of the case has niches to hold the Scanner, battery and cables. A movable locking piece guarantees that the accessories remain in their place even if there is sudden rough movement. The bed is supported on a “shock absorber”, which absorbs part of the vertical impacts.

The case’s cover has an internal backing, when closed this backing holds the HemoLight Plus to the lower bed, preventing the mixer from shifting position during its transportation.

•

The transport case may also be used as a collection table. To do this the cover must be placed with the opening facing upwards and the lower bed must then be placed on top of the cover.

The HemoLight Plus when placed in the transport case will sit between the four corner pieces on the lower bed. The front part of the HemoLight Plus must face the scanner’s “head”.
