MSI
Motion Sensing Interlock
User Manual - Original Language Version
The MSI is designed to control access to rotating machinery that
has a run-down time. The MSI relies on the detection of motion
via two sensors. Only when both sensors detect zero movement
can the key be released. The MSI has been designed to provide
the highest level of safety when installed as part of an access
control system for dangerous machinery.
Operation
MSI-FSB-F-3-110A
The Castell MSI motion sensing interlocks are typically used for machine isolation in applications in order to protect the
hazardous area from access while power is on.

1. While the power is on and a motor is running, the key is trapped in the MSI motor sensing interlock. A red LED
is illuminated.
2. Turn the key to OFF position to switch the power off. A movement sensor in the MSI unit gives a signal to
the solenoid once zero movement has been detected. This will illuminate a green LED. The key can now be
released by pushing the green button. This key can be taken to unlock the access lock on the motor unit.
3. The motor stands still and power is off until the key is replaced in the MSI motor sensing unit.
