15887 Autoloader ALE: Plate not grabbed by the table vacuum. Trendsetter_VLF This error is reported when the firmware doesn't detect the unload table vacuum buildup to greater than a certain threshold in a set amount of time. The threshold can be found in the nvs parameter table_vac_threshold (tvt) in the al section. The vacuum value read is corrected using one of the adc_offset values in the al section of nvs. In this case you want offset 0 (the first one), use "set al aoff 0". Lastly, the time allowed to buildup vacuum can also be found in nvs, this time in the altim section -> vac_generate_delay (vgt) is the name of the parameter. To check the current value, you can use the "table vac" command to display the info, you are looking for lines which look like: Unload Table Vacuum level = X (Under Threshold) Table vacuum threshold Y, offset Z "table vac on" and "table vac off" can be used to control the table vacuum; with these two and "table vac" you can test both the sensor setup and determine if the sensor is broken and need replacing.
