The TubeFlow is activated when the BW 685 S is switched on; this is indicated by a green control LED on the TubeFlow.  The control LED appears yellow for approx. 1 second after switching on, in order to check the malfunction detection.  After the test of the malfunction detection, the control LED switches to green, indicating normal operation.  In the event of a malfunction, the control LED appears yellow. 3.2 ALARMS The BW 685 / BW 685 S triggers temperature alarms and information signals: The low temperature information signal is activated when the temperature of the heat exchanger drops below 36.5 °C. The audible low temperature information signal is not active during the first 60 seconds after switch-on. In the event of a low temperature information signal, i.e. temperatures < 36.5°C, the 36.5 °C LEDs flash and the device emits an information signal every 15 seconds. The low temperature information signal is automatically cancelled after reaching 36.5 °C. The high temperature alarm is activated when the temperature of the heat exchanger rises above 42 °C. In this case, visual (flashing) and audible (continuous sound) alarm signals are emitted and the heating is switched off. The device can only be restarted and the alarm disengaged once the device has been disconnected from the power supply. Attention: The temperature alarm can also be triggered by external factors, e.g. exposure to sunlight. To reset the alarm, the mains plug must be pulled out. All alarms are alarms of “Low priority” according to EN 60601-1-8. The alarm system does not have to be verified. The alarm limits cannot be adjusted. The risk management process has found that a shutdown of the alarms is not meaningful, because it is desirable that the error (e. g. high temperature) is detected. Resetting of the alarm is only possible through disconnection of the device from mains. The operator station is in front of the device.

6 PERIODIC INSPECTIONS The periodic technical safety inspections (according to the local standards in force - e.g. EN 62353) on the BW 685 / BW 685 S and the optional tube warmer TubeFlow must be carried out at least every 12 months, by persons authorized to carry out such inspections based on their training, knowledge and practical experience. The results of the periodic inspection must be documented, along with the date, the inspecting agency and the device number. During the measurements, the heating devices may not be exposed to sunlight, draughts or other conditions which could affect the measurement. Important: If a malfunction is discovered during the periodic inspection, suitable warning signs should be attached to the device to ensure that it is not used before the required service and repair work has been carried out. CHECKING THE WARM-UP PERIOD (BW 685 / BW 685 S) This is the time taken by the BW 685 / BW 685 S to heat up to 38.5 °C from room temperature. If this time is much more than one minute, there is a malfunction. CHECKING THE CONTROL TEMPERATURE (BW 685 / BW 685 S) The control temperature is checked on the groove bed of the heat exchanger. The sensor of a suitable contact thermometer (tolerance ± 0.15 °C) is attached here, e.g. with a piece of infusion tube. The examination is carried out at a setting of 38.5 °C. The measured value is read once it has stabilized. The difference must not exceed ± 0.5 °C. If there is a difference of greater than ± 0.5 °C from the control temperature, there is a malfunction.

16

BW 685 / BW 685 S / TubeFlow

CHECKING THE LOW TEMPERATURE INFORMATION SIGNAL (BW 685 / BW 685 S) Preheat the device to 38.5 °C, then disconnect the mains plug. Hold down the button and reconnect the mains power plug. After the beep, release the button. Press the button. The device is now in an operating mode in which all alarms and signals are active but the heating is switched off. The BW 685 / BW 685 S now slowly cools down. When the temperature drops below the 36.5 °C threshold, the low temperature information signal should trigger. For reasons of safety, there is a short beep every second in this operating mode, and the STANDBY indicator (Fig. 1/4) flashes. If the low temperature information signal is not triggered, there is a malfunction. CHECKING THE HIGH TEMPERATURE ALARM (BW 685 / BW 685 S) Preheat the device to 41 °C and wait for the temperature to stabilize, then disconnect the mains plug. Hold down the button and reconnect the mains power plug. After the beep, release the button. Press the button. The device now slowly heats up to a target temperature of 42.5 °C. Observe the temperature display carefully. The high temperature alarm should be triggered at a temperature of 42 °C. For reasons of safety, there is a short beep every second in this operating mode, and the STANDBY indicator (Fig. 1/4) flashes. If the high temperature alarm is not triggered, there is a malfunction. VISUAL CHECK OF GENERAL CONDITION (BW 685 / BW 685 S) The device should be checked for mechanical damage (general condition) and for the completeness of the stickers, particularly the device label on the reverse. If there is mechanical damage to the device which could cause risk of injury or impair its functionality, this constitutes a malfunction. ELECTRICAL SAFETY (BW 685 / BW 685 S) All relevant electrical safety data should be checked, particularly the earth conductor resistance and leakage current. If a measured value is outside of the specified tolerance, there is a malfunction.

17

BW 685 / BW 685 S / TubeFlow

VISUAL CHECK OF GENERAL CONDITION (TubeFlow) The TubeFlow to be examined must first be subject to a visual check. The device should be checked for mechanical damage (general condition) and for the completeness of the device label. Furthermore, the device must not display any contamination or corrosion which could impair safety, particularly in the area of the plug connector. If there is mechanical damage to the device which could cause risk of injury or impair its functionality, this constitutes a malfunction. CHECKING THE CONTROL TEMPERATURE (TubeFlow) The temperature check must be performed at an ambient temperature of 22 °C ± 1 °C. During the measurement, the heating device must not be exposed to sunlight, draughts or other conditions which could affect the measurement. The TubeFlow heating device must be attached in its intended position according to these operating instructions. The head of the TubeFlow is inserted into the fixing clamp. The end of the TubeFlow is inserted into the groove on the fixing clamp. A suitable digital thermometer, as well as a temperature sensor with a diameter of 5 mm, is required for the temperature measurement. Insert the temperature sensor into the heating profile at the end of the TubeFlow, centrally with respect to the position of the bulge (see Fig. 4). At least 20 cm of the sensor line must be inserted into the heating profile. Switch the BW 685 S on and check whether the malfunction detection is checked. Wait for 45 minutes. After this time, the TubeFlow has reached its preset temperature of 39 °C and is evenly heated throughout. Now connect the temperature sensor to the digital thermometer. The measured temperature value is now entered into the inspection protocol. The measured temperature must be 39 °C ± 1.5 °C. Temperature sensor

OVERTEMPERATURE CONTROL (TubeFlow) An independent temperature sensor is installed in the TubeFlow warmer. The electronic system continuously monitors the sensor. The heating is permanently switched off if a certain predefined temperature is exceeded. In order to examine this overtemperature activation, a calibrated circulation thermostat which can be set to temperatures between 39 °C and 45 °C is required. Switch the circulation thermostat on. Set a temperature of 40 °C on the circulation thermostat. Insert the end of the heating profile of the TubeFlow into the water bath of the circulation thermostat, further than the additional insulation. Start up the TubeFlow. Wait until a temperature of 40 °C has been reached in the circulation thermostat. Increase the temperature on the circulation thermostat in steps of 0.5 °C, and wait until the set temperature has been reached in the circulation thermostat. The overtemperature function should be triggered at 42 °C ± 1.5 °C. As soon as the trigger temperature has been reached, the LED on the control unit lights up yellow. The temperature set on the circulation thermostat when the overtemperature alarm was triggered corresponds to the trigger temperature of the overtemperature protection of the TubeFlow. If the temperature value is outside of the tolerance range, the TubeFlow must be returned to the manufacturer for recalibration. 7 MANUFACTURER LIABILITY The manufacturer and the supplier of the device reject any liability if:  the device is not used in accordance with the directions for use.  the user is not sufficiently informed about the functioning of the device corresponding with the directions for use and the safety instructions  repairs are not performed exclusively by the manufacturer or by persons and service centers expressly authorized by the manufacturer  the device is used in places in which the electrical installations do not comply with the applicable national standards, or if the power supply during the period of use of the device is not guaranteed  original spare parts are not used or the maintenance interval is not adhered to.
