Fan Error Codes
Below are common error codes that may display in the event of a system fault with descriptions and corrective actions. Contact Big
Ass Fans Customer Service at 1-877-BIG-FANS to resolve codes that cannot be cleared or for codes not listed below.
Error Code Description and Corrective Action
Fan Controller Overheating
Ensure that the ambient temperature range around the fan controller is not in excess of 50˚C or 122˚F. If ambient
temperatures are found to be acceptable, ensure that the controller enclosure heatsink fins are free of debris and
dirt buildup.
Low AC Input Voltage
Ensure that the incoming AC line voltage is within nominal limits. For fans that operate in a range of 200-250 VAC
3Φ, the fan controller will ride through a voltage sag down to 180 VAC (-10% nominal). For fans that operate in
a range of 400-480 VAC 3Φ, the fan controller will ride through a voltage sag down to 342 VAC (-10% nominal).
Please consult a qualified electrical contractor or electrical engineer regarding facility’s power distribution for a
solution that will fit the facility’s symptoms.
Overload, Overload 1, Overload 2
These three fault codes indicate that the motor has experienced load torque in excess of design limits. Check the
fan blades for obstruction and abnormal buildup of debris or dust. Listen for abnormal gear noise while the fan is
running. Contact Big Ass Fans Customer Service at 1-877-BIG-FANS for additional troubleshooting.
External Fault
This fault indicates that a customer-installed fault trigger has been activated on multi-function input terminal 3.
MFIT 3 is factory configured as an NPN input; pulling this input down to DC Common will initiate fan shutdown.
See “Basic ESFR Interfacing” on p. 40.
Ground Fault
A short circuit to ground has been detected in the motor circuit. Check the motor wiring at the motor junction box
and fan controller output terminals. This fault may also indicate a defective fan controller output transistor module.
Communication Error
Confirm that the fan controller was not preordered to interface with Modbus/RTU communications protocols.
This error will occur if fan controller addressing has been modified from factory defaults and interfaced with the
standard wall control unit. Verify wiring of the data cable between the fan with the standard wall control unit. Verify
wiring of the data cable between the fan controller and the wall control unit. See “Wiring Data Cable for Wall
Control” on p. 25.
Analog Signal Error
When using a remote 4-20 mA analog speed reference in External/Remote mode (ACI), this fault indicates that a
failure has occurred in the current loop. Verify proper wiring, supply voltage, and loop impedance.
Input Phase Loss
This fault indicates the loss of input voltage on L1, L2, or L3.
