Grab Wire Safety Rope Switches
Designed to be mounted on machines and sections of conveyors which cannot be protected by guards.In contrast to traditional mushroom head type emergency stop buttons, Grab Wire Safety Rope Switches can initiate the emergency command from any point along the installed rope length and provide robust Emergency Stop Rope Pull protection for exposed conveyors or machines. In combination with a dual channel safety monitoring relay IDEM's Guardian Line Series Grab Wire Safety Rope Switch System can be used as emergency stop devices monitored for up to Category 4 to EN 954-1 or PLe ISO 13849-1.All conform to ISO 13850 and IEC 60947-5-5 and they have a positive mechanical linkage between the switch contacts and the wire rope. The switches have wire breakage monitoring.On pulling the rope, anywhere along the length, the safety contacts are positively opened and the auxiliary contacts are closed. The swtiches are mechanically latched and can then only be returned to the operational condition by pressing the blue reset button as required by ISO 13950.An optional 2 colour LED indicator is available to enable switch status to be viewed from a distance.

IdeSafe Bus System: 2 Wire Safety Communications
IDESAFE BUS SYSTEM: 2 WIRE SAFETY COMMUNICATIONS FOR USE WITH ROPE SWITCHES COVERING LONG LENGTHS (UP TO 5KM).
The IdeSafe Bus System allows the IDEM GLH Safety Rope Switches to be connected in series to protect long conveyor lengths up to 5Km whilst maintaining diagnostics and safety integrity.
Each switch contains an address programmable module to give individual diagnostics of the switch status and is readable at the control cabinet.
Open circuits are detected.
The whole system is connected in series by a simple 2 wire connection system from switch to switch making wiring easy and simple to install.
Safety integrity is maintained throughout via positively opened switch contacts connecting to the transmission bus to maintain PLe to ISO13849-1, SIL3 to EN62061 and Category 4 to EN954-1.
Communications capabilities - the system can be interfaced to most Text Displays, Touchscreens, PLCs and PCs via the gateways for Modbus and Profibus.
Up to 63 switches will connect to one IdeSafe Bus.
High flexibility allows the easy expansion of the system step-by-step by the installation of additional safety input modules.
Basic elements required are Master Module, Safety Receiver and Rope Switches with Input Modules.

GLS-AR: Grab Wire Auto Reset Trip Switch
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.
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. The switch cannot be used in safety applications, it is only to be used for indication.
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.
