Advanced setup LEDs integrated into the Dynapar H Series encoders make installation and troubleshooting easier than with competitive devices, it's claimed. A series of three dual-color, red-green LEDs indicates critical functions during installation and setup. When initially wired, the LEDs will flash green-off or green-red (depending upon output configuration) to indicate normal operation. Most encoders have no way to inform users if they are wired correctly or even if they have power. These encoders will precisely identify power problems and specific wiring errors. Indicator LEDs are available on all H Series encoders.
