GLS-AR: Grab Wire Rope Pull Auto Reset Trip Safety Switch

Approvals

ROPE PULL OPERATED. AUTO-RESET STOP SWITCH.

Grab Wire Auto-Reset Stop Rope Switches are mounted on machines and sections of plant conveyors to initiate a momentary control signal command from any point along the installed rope length.

Designed and manufactured in the United Kingdom the GLS-AR is offered with either a die-cast painted yellow or stainless steel 316 housing and is extremely robust for virtually all applications.

Pulling the rope causes instant tripping of the control circuit contacts.

Ideal for normal stop circuits where manual resetting of the switch is not required. This switch is not an emergency stop, it is a “trip” switch with automatic reset.

The switches have a positive mechanical linkage between the switch contacts and wire rope as per IEC60947-5-1. The switches are brought into the operational condition by pre-tensioning the rope by use of a tensioner device which clamps the rope and then hooks to the switch eyebolts. Correct tension can be observed by viewing the tension indicator on the switch housing. Once tensioned the switch contact blocks are set to the operational condition, i.e. Signal contacts Closed – Auxiliary contacts Open.

All of the switches have wire breakage monitoring. On pulling or breakage (tension loss) of the rope, the normally closed Signal contacts are Opened and the Auxiliary contacts are Closed. The switches will be returned to the operational condition as soon as the rope returns to the set position.
