(Optional) Table Limit Switch

A recommended option for any rack conveyor dishwasher is a table limit switch. The limit switch is installed at the end of the clean-end table and is designed to stop the conveyor and pumps in the event that dish racks back up on the clean-end table. This feature prevents possible damage to the conveyor due to jamming. The operation of the table limit switch is described below.
