| Model 3380-C Two-Hand Machine Control Anti-Tiedown Monitor |
| Series Description: Nolatrons anti-tiedown controls are used in conjunction with two start switches to help protect machinery operators. The 3380 series helps to comply with OSHA, which requires a machine operator to have both hands on the start switches in order to start a machine cycle. This minimizes the possibility of the operator starting the machine while one hand is in the work area. Both start switches must be activated within a fixed time interval to energize the output. This prevents an operator from tying down one of the switches while continuing to operate the machine. The 3380 uses redundant positive guided output contacts which are cross-checked before every machine cycle. A single component failure will cause the control to shut down in a safe mode. |
| Series Operation: MOMENTARY OUTPUT: In order for a machine cycle to begin, both start switches must be pressed within .5 sec. (this time is internally adjustable). The output will remain energized as long as the start switches are depressed. The optional Reset switch can be opened to end the machine cycle regardless of whether the start switches are depressed. In some applications the Reset switch is used as a means to provide a single stroke of the machine. Both start switches must be released before another machine cycle can be started. If either start switch is tied down, the cycle cannot be repeated. MAINTAINED OUTPUT: In order for a machine cycle to begin, both start switches must be pressed within .5 sec. (this time is internally adjustable). The output will remain energized as long as the start switches are depressed. Closing the optional Hold switch will allow the load to remain energized after the start switches are released. The Hold switch must not be closed until the pinch point is passed. The Hold switch should stay closed for the rest of the machine cycle. The Reset switch can be opened to end the machine cycle regardless of whether the Hold switch is closed or the start switches are depressed. Both start switches must be released before another machine cycle can be started. If either start switch is tied down, the cycle cannot be repeated. |
