We’ve recently installed a Telemecanique XY2-CH Emergency Stop Grab Wire (Trip Wire) Switch System. This was used as part of a larger PLC Control System that we designed, supplied and installed for a customer who works within the automotive parts industry. The PLC Control System is responsible for controlling the conveyor line which transfers the automotive parts through 3 x Robot Spray Paint Booths and ensures they are spray painted the correct colour as required. Multiple part types are possible and the operators load and unload these automotive parts in a designated area of the conveyor line. Following a safety review it was deemed that these load and unload areas of the conveyor system required additional Emergency Stop protection and it was decided that a Grab Wire or Trip Wire Switch System would be up to the task.
The components we used in the Grab Wire Safety System included the following items:
Telemecanique XY2CH13270 Grab Wire Booted Push Button by Schneider Electric
Telemecanique XY2CZ702 End Spring for XY2-CE by Schneider Electric
Telemecanique XY2CZ301 10m Cable for XY2-CH by Schneider Electric
The XY2CH13270 was electrically connected to the Emercency Stop Safety Circuit which was located within our Main Controls Panel and included:
Pilz PNOZ S3 Safety Relays x 2
Pilz PNOZ S11 Safety Relay x 2
