Description

Nolatron 3380 Two Hand Machine Control, Anti-Tiedown Timer Simple Type: Anti-Tiedown Timer Nolatron's 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.
