1. Motion Sensing Interlock GP User Manual Original Language Version Castell The BEMF Motor sensing Interlock is designed to control access to rotating machinery The BEMF unit relies on the measurement of the electromotive force generated by the windings of an electric motor Only when the motor has stopped will the BEMF drop to zero and allow the release of a Castell key The unit is used for connection to AC and DC motors including DC braking systems The BEMF has been designed to provide the highest level of safety when installed as part of an access control system for dangerous machinery BEMF FSB F 3 110A Operation The Castell BEMF switch disconnector is typically used for machine isolation in applications in order to protect the hazardous area from access while power is on BEMF Switch Disconnesctor O Power is on key is trapped Red 2 Turn the key to OFF position At zero 3 Key is released power is off and LED is illuminated movement detection a signal is sent the motor stands still to the BEMF to energise the solenoid A green LED is illuminated Release the key by pushing the green button 1 While the power is on and a motor is running the key is trapped in the BEMF motor sensing interlock A red LED is illuminated 2 Turn the key to OFF position to switch the power off A movement detector gives a signal to the BEMF unit once zero movement has been detected2.
