Rope Switch Lifeline 4 EX Guardmaster

The Lifeline 4 rope/push button operated emergency stop device, has
been designed to meet the stringent requirements for emergency stop
equipment, EN418. The Lifeline 4 system can be installed along or
around awkward machinery such as conveyors, roller machinery and
provides a constant access emergency stop facility. The Lifeline 4 features a cam-action mechanism which ensures that the contacts are immediately latched open on actuation and can only be reset by intentional turning of the blue reset knob. This also protects against nuisance tripping due to thermal expansion, machine vibration or rope bounce. The Lifeline 4 is suitable for spans of up to 75 metre in length
and can reduce the number of emergency stops along exposed
machines. The unit provides 2 N/C safety contacts and 1 N/O auxiliary
contact actuated by wire deflection or a mushroom head emergency stop
button giving total E-stop access even at the extreme ends of the span. A robust construction in heavy duty die-cast alloy, sealed to IP66, with a stainless steel actuator shaft to withstand harsh conditions. The EX Lifeline 4 incorporates a sealed flameproof contact block and is suitable for Zone 1 & Zone 2 environments. Available pre-wired with 1 N/C & 1 N/O contact, it offers the same safety features and operating
principles as the standard version.
