SafePoint™ Fail-Safe Rotary Paddle
With a de-energizing motor like the KA model, and its own fail-safe features, the SafePoint™ Rotary Paddle is the greatest deal in level controls. The micro-processor based technology monitors the status of the electrical and mechanical operations, to determine the difference between material presence and a process failure.
When material is present, the shaft stops rotating. Inside the unit, the motor is still rotating the magnetic disks which engage a contact and shut the motor off. The external light will indicate the material presence on the outside of the tank. When material is removed, the tension spring restarts the motor, the indicator light switches, and the unit is returned to normal operation.
A failure would be recognized through the micro-processor by the lack of shaft rotation, with no contact made to shut the motor off. This will change the indicator light and send a signal from the fault switch to signify an error condition.
