| Model 4480 Two-Hand Machine Control Anti-Tiedown Monitor |
| Series Description: Nolatrons Model 4480 Switch Monitor provides two-hand control for presses, welders, molders, and various production machines. The 4480 also helps to comply with OSHA, which requires an operator to have both hands on start switches in order to begin a machine cycle. This minimizes the possibility of an operator having a hand in the work area when a machine cycle is started. If one or both switches are tied-down, the control will not allow a new machine cycle to begin. |
| Series Operation: As each start switch is closed, it will be delayed for .075 seconds* before an internal relay is energized. If both start switches are closed within a time of .5 seconds**, the output contact will close and the load will energize. The output contact will remain closed until one or both start switches are opened. Both switches must be released before another cycle is initiated. MAINTAINED OUTPUT An optional Hold switch can be wired into the circuit fo the 4480 (see wiring diagram) to provide a maintained output. When the two start switches are activated and the Hold switch is closed, the load will remain energized even after the start switches are released. The Hold switch must not close until after the pinch-point is passed, and should remain closed for the rest of the machine cycle. Opening the Hold switch will de-energize the output. If the optional Reset switch is opened at any point during the machine cycle, the output will de-energize and the control will reset. Both start switches must be opened and the Reset switch must be closed before another machine cycle can be initiated. |
