Table 4-1 Error Codes 4.5 TROUBLESHOOTING (PROBLEM ISOLATION) This section has been divided into two major areas; clinical and technical. Clinical problems can generally be resolved by the user. Technical problems may require resolution by a qualified technical service person. The error code table below indicates Technical problems with an asterisk (*). Error codes are displayed on the front panel LED’s of the Accutorr Plus. TYPE CODE DESCRIPTION REASON NIBP 8810 Retry - Unable to Motion artifact, cycle time-out, weak pulsations or no pulsations. Measure A triple beep tone is generated. 8811 Retry - Pump Higher Insufficient cuff pressure. A triple beep tone is generated. 8812 Stop - Cuff Excessive cuff pressure detected by the software. A triple beep Overpressure tone is generated. 8813 Stop - Unable to 4 successive measurement attempts failed. A triple beep tone is Measure generated. TEMP 8830 Check Probe Tissue contact may have been lost. (PTM) 8831 Replace Probe Defective probe or connection. 8832 Battery Low The 9V battery needs replacement. SpO2 8850 No Sensor No sensor connected. 8851 Sensor Off Sensor not on patient. (Datascope and Masimo SpO2 only) 8852 Interference Interference on signal. (Datascope and Masimo SpO2 only) 8853 Pulse Search Unit cannot find signal. (Nellcor SpO2 Module will report “Pulse Search” -8853- when the sensor is not on the patient.) 8854 Weak Pulse Weak pulse detected. (Datascope and Masimo SpO2 only) 8855 No Pulse No pulse detected. (Datascope SpO2 only) 8856 Check Sensor Sensor problem. (Datascope and Masimo SpO2 only) 8857 PR250 Pulse rate is greater than 250 bpm. (Datascope SpO2 only) SYSTEM 984* NIBP Hardware Failure NIBP A/D failure detected. 985* NIBP Overpressure Circuit not Programmed The overpressure circuit is not set to the current patient size. 986* NIBP Overpressure Circuit not Tracking The two pressure transducers are not tracking each other. 987* Stop - Hardware Excessive cuff pressure detected by hardware over-pressure Overpressure sensor. A triple beep tone is generated. 988* TEMP Bad Calibration Thermometer needs calibration. 990* TEMP Illegal Mode Thermometer switch is set wrong. 991* TEMP Module Failed Thermometer internal failure. 995* SpO2 Uncalibrated SpO2 fails calibration check. 996* SpO2 Failure SpO2 failed self-test. 4-4 Revised 02/15/00 Accutorr Plus Service Manual Chapter 4 - Repair Information
4.5.1 Isolating the Problem, System Level 1. Determine if the problem is in the main NIBP unit or one of the add on accessories. 2. If the problem is in the accessory, replace the 9 Volt battery in the temperature module, and check the recorder unit for correct paper, correct installation and paper jams. 3. If the problem is in the main NIBP and/or SpO2 section, rule out these simple problems first: If AC power is available, then the green LED adjacent to the front panel On/Off keys should be illuminated. If not, connect the power cord to live power outlet. If green LED fails to illuminate, there is a probable power supply malfunction. Check the battery operation LED. Steady ON indicates battery operation. A flashing LED indicates a near depleted battery. If the green LED is NOT On, then the battery or power supply/charger may be suspect. Confirm correct operating parameters selection, i.e., correct patient size selection, (Adult, Neonate, Ped.) and NIBP cuffs to match. In units with SpO2, verify that a sensor is connected to the unit and it is of the proper type/size. Verify the proper battery charge profile is selected for the installed battery. 4.5.2 Isolating the Problem within the Main Unit Problems within the main NIBP and/or SpO2 unit are categorized broadly into power supply problems and NIBP and/or SpO2 detection and display. For a monitor that will not even turn on, proceed to Power Supply and Battery Tests, otherwise skip to Diagnostics Test and beyond. 1. Power Supply and Battery test: The main power supply output voltages should be verified under normal instrument loads. Voltages are shown on the System Block diagram, which is located in chapter 2 of this manual. Below are the tolerances for the voltages shown: 5V = 4.9 - 5.1 12.5V = 12 - 13 15V = 14.5 - 15.5 2. Perform Diagnostics Test 01 through 12 . Repair or replace circuits or components that fail to pass the Diagnostic Test. 3. Trend circuits test: Obtain a minimum of five NIBP measurements and simultaneous SpO2 and Temperature readings if the Accutorr has those options. Confirm Trend storage function as explained in sections 1.3.6, To View and Deleted Stored Data (Trend Mode) and 1.3.12, Recorder.
