  • Page 10 The ICC units are equipped with a system for error detection, error indication and error memory. Every error is labelled with an error number (ERROR No.). The ICC 50, ICC 80 and ICC BIPOLAR units store the last 20 ERROR numbers. Test program 2 indicates the stored ERROR numbers. The most recent error is in Memory location 1.
  • Page 11 Test programs ICC 50, ICC 80, ICC BIPOLAR Range: 1…99 seconds. This value must be stored in memory by pressing the CUT effect key for about 3 seconds. Refer to Test program 1. It is possible to exit the test program without saving a new value to memory by briefly pressing the CUT effect key.
  • Page 12 Test programs ICC 50, ICC 80, ICC BIPOLAR By pressing the CUT effect button, the voltage is decreased to 50 volts. By pressing the CUT effect key again, the test program is exited. Test program 12 Adjustment of the phase control for the HF generator This adjustment is made as the generator idles, but with the monopolar patient lines connected.
  • Page 13 Test programs ICC 50, ICC 80, ICC BIPOLAR At the NE socket a resistance of 260 ohms is connected via a standard NE cable. Then the reference value for the NE monitoring is automatically adjusted by the unit, which is indicated by the appearance of an unbroken line (»—«) in the COAG display and the illumination of both the red and the green NE LEDs.
  • Page 14 Test programs ICC 50, ICC 80, ICC BIPOLAR Verification of the modulation timer and the modulation monitor (»t.t.«) At the test program start, the timer is initialized and switched on. Activation using the CUT footswitch turns on the generator (with the output relay open) and the feedback is measured. In the COAG display, the measurement value for the feedback is indicated.

    CHAPTER 2 ERROR list...
  • Page 19 Troubleshooting for ICC family equipment The ICC equipment family is equipped with an error detection system which records the last 20 (ICC 50, ICC 80, ICC BIPOLAR) errors in an ERROR list and saves them in memory. This error memory can be called up via Test program no.
  • Page 20 ERROR nos. 1–13 Error no. Explanation and remedy Activation time limit reached. If the activation time limit has been set too short, extend this by using Test program no. 3. During monopolar activation, the NE monitor produces an impermissible value. Check whether the NE is correctly applied and connected to the unit.
  • Page 21 ERROR nos. 14–25 Error Explanation and remedy Incorrect dosage during CUT: Voltage 20% too high. Equipment error: Tech. Service. Incorrect dosage during FORCED: 20% too high. Equipment error: Tech. Service. Incorrect dosage during SOFT or BIPOLAR: Voltage 20% too high. Equipment error: Tech.

    CHAPTER 3 Adjustment and testing instructions...
  • Page 27 The following instructions for adjustment of HF surgical units ICC 50, ICC 80 and ICC BIPOLAR allow the service technician to perform all adjustment work. This adjustment work must only be performed by the manufacturer or by third parties expressly authorized to do this by the manufacturer in consideration of the particular safety requirements for electromedical equipment.
  • Page 28 ICC 50, ICC 80, ICC BIPOLAR An essential component of the ICC 50, ICC 80 and ICC BIPOLAR unit is the microcontroller (68HC11A1), which directly influences almost all functions of equipment and unifies a large number of functions through its capabilities.
  • Page 29 Adjustment and testing instructions ICC 50, ICC 80, ICC BIPOLAR Basic initialization Attach the shorting bridge to J7. Switch the unit on. At the same time, basic initialization is automatically performed insofar as this has not already occurred with the respective microcontroller.
  • Page 30 Adjustment and testing instructions ICC 50, ICC 80, ICC BIPOLAR Setup of the phase control for the HF generator Connect the monopolar patient lines with no load. This is important for a precise setup! Connect the oscilloscope and probe at MP4 to MP5. Probe 100:1 recommended.
  • Page 31 Adjustment and testing instructions ICC 50, ICC 80, ICC BIPOLAR Calibration of the HF power output Connect the monopolar patient lines to the HF power meter (APM 600). Activate Test program 13 (only possible in Special Test Mode, see above).
