15621 Autoloader ALE: no plate on unload X-axis or low vac, can't continue Platesetter_VLF The machine was expecting a plate on the unload x-axis table but it did not detect one. To verify that there is a plate on the unload table, the system polls the vacuum sensor until either vacuum reads higher than threshold or a timer expires. If the vacuum is less than the set threshold then, the system will issue this error. Verify that the NVS parameter vac_threshold_x for the threshold is set to the appropriate value Verify that the suction cups are place at the right location to grab a plate Verify that the suction cups are in good condition There may be a problem with the air pressure system ..\..\ShowAllErrors.htmFirmware 0 Error Index ..\..\ShowAllCommands.htmFirmware 0 Command Index ..\..\ShowAllNVS.htmFirmware 0 NVS Index Updated: Wed Jul 16 19:33:16 2008 PST
