EN/ISO 13850:2006. The XY2 CB switch must not be used if the system requires an angled installation of the release wire; this is possible with the XY2 CE. In this case, the sum of the angles by which the release wire is bent must not exceed 180°. Emergency stop pull cord switches XY2CE & XY2CB, Telemecanique. These emergency stop release wire switches are designed to reduce the risk of injury to individuals and damage to machines or production products. They can be activated by a person with a single movement when a normal emergency stop function is not available, and they also trigger if the release wire breaks. The switches feature forced opening contacts, with the activation of the switch occurring through forced operation. The switch latches in the triggered position (normally open safety contacts open). The normally closed contact is only for signaling purposes. Includes a reset button, which allows the safety contacts to be closed again. Restarting the machine must only be done by manually operating a control device within the machine's start circuit, which is located some distance from the release wire switch. The recommended distance between cable holders is 15 m. (For XY2-CB30, a distance of 20 m is recommended.) The XY2 CE1A296 comes with a signal light.
