Electronic Fault Detection Capabilities of the HS35iQ Encoder

The electronic fault detection features of the HS35iQ encoder help simplify the troubleshooting process by providing a visual indication of an encoder error. The 4 events which can trip the electronic fault LED of the HS35iQ encoder include fatal encoder errors, low input voltage errors, fault monitoring errors, and the position sensor health warning. In addition to the LED, located on the housing of the encoder, a fault output signal is also sent from the encoder’s primary and diagnostic connector to whatever monitoring device you have the encoder wired to.
