5.2.3.1 Auto-Cleaning

Texas Instruments proprietary Auto Cleaning Mode is composed of five bursts, enumerated bursts (19, 8, 9, 13, 14). Auto-Cleaning mode utilizes Texas Instruments' mass detection algorithm to invoke the cleaning algorithm. The settings for enumerated bursts (8, 9, 13, 14) are the same as those used in Water Mode. The burst parameters for enumerated burst (19) must be set according to Section 4.3.3 and Table 5-2. This burst must not be directly updated by the user in the GUI. Rather, the burst is auto-updated by setting up and running the calibration mode. The Temp burst (23) can also be added to the Auto Cleaning Mode integrate auto de-icing capabilities. An example de-icing sequence is (19, 23, 16 or 17, 8, 9, 13, 14). If mass is detected on the lens by burst 19 and burst 23 determines the LCS temperature is below the threshold, USER_Params_Deice_TempThreshold_C_Q21, the heating burst (16 or 17) is executed and followed by the remaining water bursts (8, 9, 13, 14). If mass is detected on the LCS by burst 19 and burst 23 determines the LCS temperature is above the threshold, USER_Params_Deice_TempThreshold_C_Q21, the next burst, typically a heating burst, is skipped and the remaining water bursts execute. If burst 19 determines there is no mass on the lens, then all following bursts do not execute.

Note: Auto Cleaning Mode can be run continuously by checking Continuous Auto Mode check box located in the Mass Detect Parameters section. Requires device to be in Active mode (PWR_CTL = 0x00) and initialized.
