460 kHz, with a maximum power as indicated in Section 3.7. The AtriCure ASU is designed to operate with the AtriCure Handpiece. The ASU and Handpiece are designed for use without a neutral electrode. The Footswitch is the input device used to activate RF energy delivery. -
Page 9: Power On Self-Test
SERVICE MANUAL Power on Self-Test The ASU goes through a Power On Self Test (POST) every time the power switch is turned on. The POST is software driven; it is a comprehensive test of the generators components. If an Error is generated during this test, the ASU goes into FAULT Mode. This Mode is entered upon detection of any unrecoverable error condition during any Mode of operation. - Page 10 SERVICE MANUAL Configuration Register Error • Code P08 is generated if a configuration register error is detected. MCU COP Error • Code P09 is generated if the COP watchdog timer expires. Switch Stuck Test • Code P10 is generated if the Footswitch is depressed during the POST. Real Time Clock Test •...
