CHAPTER 9: GEN250/251CARD LED INDICATORS
The GEN250/251card has six LED indicators for general troubleshooting. See Figure 9.1 for the location
of the LED’s.
1. The “Power” indicator informs the user that the GEN250/251card is getting power. If the Drive is
powered up, and this light is not illuminated, ensure the ribbon cable is properly connected.
2. The “Reset” indicator is illuminated as long as the power light is illuminated. If the GEN250/251card
appears to be having problems, and the reset LED is not illuminated, contact Horner APG’sTechnical
Support.
3. The “Transmit” indicator flashes when data is transmitted to a PC while reading the configuration from
the GEN250/251card with the software configuration tool.
4. The “Receive” indicator flashes when data is received while writing a configuration to the
GEN250/251using the software configuration tool.
5. The “GENA OK” indicator is illuminated unless there is a fault with the GENA board.
6. The “COMM OK” indicator illuminates when the GENA board is communicating with the GBC properly.
If the “COMM OK” LED is not illuminated after configuration, check the following:
a. Make sure the GEN250/251configuration Global Data and Directed data length matches the Summary
Global Data words, and the Directed Control Data words (In the software configuration tool).
b. Make sure the Cable is wired correctly between the GBC and the GEN250/251card.
c. Check the GBC configuration (LM90 Configuration package). The Global data length, and the
Directed control data length must match the input length and the output length respectively.
