(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.

1.If the dishwasher is running and the table limit switch (TLS) is activated, the GREEN cycle light remains illuminated and the pumps and conveyor drive stop.

2.If the table limit switch (TLS) is deactivated within 5 minutes the dishwasher will resume the cycle where it left off; after 5 minutes the green light goes out and the START button must be pushed and a rack inserted into the machine.

3.Any dish racks left in the machine after 5 minutes have elapsed must be removed and processed again.

4.To restart the dishwasher, make sure the table limit switch (TLS) is clear, then push the GREEN START pushbutton and insert a rack into the load end of the machine. The green cycle light will illuminate; the pumps and conveyor motor will run.
