USING THE 8X60

In order to have a system that does not miss any circuit must be able to detect quadrature edges a

WATCHDOG CIRCUIT

A fault-detection circuit constantly monitors the encoder's active-low signal is generated.

Fault conditions detectable by this circuit include: -LED light source failure or aging -Defective photo-detectors

-Contamination of the code disc or other optical components -Localized code disc defects such as chips or cracks
