ANTI-LOCK-IN DEVICE ADAPTED FOR SLIDING DOORS
Castell has developed a new version of its Entry Safe key interlock. Designed to control access to hazardous areas, the latest incarnation of the device can now be fitted to sliding, as well as hinged, doors.
Entry Safe is normally used on machine guarding where existing tongue switches isolate machinery before access to hazardous areas can be gained. The prevailing risk associated with tongue switches is that the operator may disappear from view after passing through the open guard. Inadvertently, a second operator could then lock in the first, thereby putting him at risk of injury when the machine is restarted.
Entry Safe addresses this danger by ensuring that the operator is safe at all times and has complete control over the restarting of machine. It works by latching the door in a locked position. When the door is partially opened, Entry Safe unlocks and releases a key into the operator’s hand. This key is retained by the operator while they are inside the hazardous area, and during this time the interlock prevents the guard door being closed.
Aside from tongue switches, Entry Safe can be used in conjunction with hinge, magnet, coded or reed switches, and even non-contact switches.
Adding a lock-out multi-clasp to the interlock enables multiple personnel (e.g. mechanical, electrical and CNC engineers) to carry out safe and simultaneous machine maintenance.
