Lifeline 3
Description
The Lifeline 3 is a cable (rope) operated emergency stop device
designed to meet the stringent requirements of EN 418 (Safety of
Machinery—Emergency Stop Equipment). The Lifeline 3 system
can be installed along or around awkward machinery such as
conveyors and provides a constant-access emergency-stop facility.
The Lifeline 3 is the only device of its kind to incorporate the
following features in one unit making it the most versatile cable
switch on the market.
1. The positive-mode mechanism ensures that the contacts are
immediately latched open on actuation and can only be reset by
the intentional action of turning the blue reset knob. The design
also protects against nuisance tripping and the effects of thermal
expansion.
2. The cable-status indicator makes the system easy to set up and
maintain for spans up to 30m (98ft).
3. Four sets of contacts are provided: 2 N.C. + 2 N.O., 3 N.C. +
1 N.O., or 4 N.C. contacts.
4. Sealed to IP67 with rugged construction using die-cast alloy and
stainless steel to withstand harsh conditions.
Features
• Switches up to 30m (98ft) span
• Universal mounting and operation
• Switch lockout on cable pulled and cable slack
• Cable-status indicator on switch lid
• Industry standard fixing centres to DIN/EN 50041
• Quick disconnect styles available.
