Corrective Action:
- Ensure VFD is receiving power. (Check receptacle with multimeter where VFD is plugged in) Check power at each fan that is showing fault. If fans are on one controller, while checking power, ensure that there are not duplicate IP addresses.
If duplicate IP address are found, there are two options to reprogram.
-VFDs must be sent back to factory for reprograming.
-Customer can reprogram drive in field. (Call Hunter Industrial Tech support for reprograming)
Once power and IP addresses are confirmed, move to step two.
- Ensure Cat5 cables are plugged in and secure at both ends. Use Cat5 tester to ensure the cables can communicate. Ensure that the cables are no more than 300 feet without using a repeater. Once it is confirmed there is no issues with the communication cables, call Hunter Industrial Tech support 629-216-4214).
