Again place the weight piece onto the tray and check if the adjustment was effective. If the net value on the display’s readout is greater than 2g than the real value. Keypad with Display to adjust the HemoLight Plus in case the option is taken to calibrate the equipment whilst it is open (Part number 070187003). When the value on the display converges to the standard weight value (with a variation of ± 2 g). check the system’s behavior with the weight piece placed at the 4 corners of the tray. checking the readout at the center and at all 4 corners. place a calibrated weight piece of 500g on the center of the tray. For this position on the scale the variation may not exceed 3 g. Repeat this step as many times as is necessary to obtain the ideal response. Wait for the zero process to finish. Power the equipment ON. Press the SCALE key. The calibration routine may be carried out with the equipment opened or closed. then the calibration potentiometer must be adjusted until the correct value is achieved. Replace the standard weight piece with one of 1000 g. When the display shows 0 g. If the option is taken to carry out the process with the equipment open. Remove the weight piece from the tray and press ENTER then wait for the display to show DATE and TIME. Wait for the zero process to finish. then it will be necessary to use the auxiliary display and the equipment must be checked after it is installed in its housing.

Length of time that the HemoLight Plus remains powered on. the batteries will not be used. some of these are: Battery type (alkaline or common). set in a compartment on the bottom of the HemoLight Plus. I The batteries life expectancy may vary and is influenced by a number of factors. 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. Fresenius Kabi HemoLight Plus QL-38/08 04/2011 Page 34 of 77 . Therefore the longer that the HemoLight Plus remains powered on the longer the batteries will last. the batteries will only come into operation when the equipment is completely powered off.8 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. either to mains or to the primary battery.

The change of batteries must be done with the HemoLight Plus powered on. Do not insert anything else into the battery compartment other than the batteries. Three new batteries.8. Carefully insert the batteries as described in this manual. If its power is supplied via the primary battery. if the equipment is not powered on then the memory’s data and its configuration are lost. Even if they have been purchased in this condition do not use it. After the opening animation is displayed press the SCALE key. • • A Phillips screw driver. either with mains power or primary battery. When changing batteries always use new batteries of the same brand. The discarded batteries must be recycled. With a Phillips screwdriver remove the screws and open the battery compartment. neither drag or lift the equipment using the tray. the spring in the holder is where the negative terminal of the battery is placed. if its power is supplied by the primary battery. Close the battery compartment using the Phillips screws.

Connector RJ11 – 2 active routes – RS485 Interface Transmission rate 38400 Baud 6.3 RS232 Serial Interface The HemoLight Plus has two serial ports.5. Once the PC sends a piece of information. 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. Fresenius Kabi HemoLight Plus QL-38/08 04/2011 Page 49 of 77 . The output of the 75176 is made up of a differential pair. One of them is used by the Scanner to obtain the data from reading a barcode. 5. This signal is used to check the charge condition of the memory batteries. 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 load cell is of the “single point” type. 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).

It is used to limit the output of the amplification stage to this value. After amplification the signal passes through a high pass filter. Whenever a piece of data is recorded or read the slave confirms the operation. This potentiometer is used to calibrate the scale and is accessible to the equipment user.9 V). The voltage value across this pin will be proportional to the weight placed over the load cell.3. 6.9 V so that is able to obtain a symmetrical power supply for amplification (+ 9 V and . It is a 12 bit A/D converter used to obtain the amplified signal from the load cell. The entire scale circuit is supplied with 9Vcc (U21). and A/D pre-converter filter. The converter 7660 (U24) generates a signal of . Analogue channel 1 is pin 40 of the Tiny Tiger (U1). This channel monitors the primary battery voltage. The amplifier circuit is an instrumentation amplifier built up of 3 op.3. To increase its sensitivity this capacity is reduced by the by the amplifier circuit to 1kg. when low will delete the data from the Smart Memory Card Memory. 6. The input of the third logic channel is pin 39 of the Tiny Tiger (U1).3. and if the data is recorded or read. please consult item 6.Chapter 6: Electrical Diagrams and Circuit Description of the HemoLight Plus For a piece of data to be recorded it will be necessary for the master to send a start signal. Please consult item 6. The amplifier’s gain is changed through potentiometer R53. At the input to the filter there is a 5V6 Zener diode.5 Analogue Inputs The HemoLight Plus uses three analogue inputs to obtain external data.3. amps OP07 (U23.6 The Scale Circuit The Scale’s Circuit is made up of the load cell. the data will follow in sequence. It is also a 12 bit analogue converter used to obtain the voltage on the batteries of the HemoLight Plus. So that the data is valid it will be necessary for the SCL signal to be high.3. after this signal has been sent the address will follow.6 for information on this circuit. The motor will make the closing movement when pin 15 on the Tiny Tiger is at 0V. When the clamp reaches its maximum opening. Whenever one of them is activated a 0V signal is transmitted to one of the “AND” gates.8 The Clamp Circuit The clamp circuit basically constitutes of a 9Vcc motor and 3 logic ports. 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. Fresenius Kabi HemoLight Plus QL-38/08 04/2011 Page 51 of 77 . the optocoupler U21 will cause relay K2 to close thus placing the motor into operation.Chapter 6: Electrical Diagrams and Circuit Description of the HemoLight Plus 6.3.3. the 9Vcc voltage across the motor is inverted causing the motor to take up both rotation directions. The optocoupler is used to isolate logical circuits (control) of the motor circuit. that for each condition.7 The Oscillating Tray Circuit The tray movement is carried out by a 9Vcc motor. This signal undergoes an inversion at the “NOR” 74LS04 (U4) gate causing the same effect as previously mentioned on the gate. with two of them being “AND” 74LS08 gates and one "NOR” 74LS04. Whenever instructed by the Tiny Tiger. The operating logic is as follows: The clamp has two end of travel switches. 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. thus starting the clamp opening movement. 6.
