The ZS80 is designed to provide continuous emergency stop control along exposed areas of machinery and conveyors which present hazards tom operator/ maintenance personnel. Unlike E-Stop pushbuttons, emergency cable-pull systems can be actuated at any point along the "trip wire". The unit features a double-break contact blocks offering a choice of two positive-opening NC contacts and two NO contacts, three positive-opening NC contacts and one NO contact, or four positive- opening NC contacts which change state when the cable is pulled or goes slack. Thus the switch can be actuated if an operator falls into, is pulled into, or leans on the trip wire. In addition the unit features an integrated E-Stop pushbutton, a position indicator for easier installation, a lever-actuated reset, three cable entries, and an optional signaling lamp.. The unit is capable of spanning lengths of up to 75 meters. Its rugged, metal housing and watertight design (IP 67) make them ideal in hostile environments. The units meet EN 418, IEC/EN 60947-5-1, and IEC/EN 60947-5-5, with UL and CSA pending.
