What does 'Underspeed Fault (Blades Too Long)' mean for my MacroAir Technologies Fan, and how do I resolve it?
If your MacroAir Technologies Fan shows an 'Underspeed Fault (Blades Too Long)', verify the correct blades are installed, the correct number of blades are installed, and the correct blade setting is selected.
What does 'Blade Detect Failed' mean for my MacroAir Technologies Fan?
If your MacroAir Technologies Fan displays a 'Blade Detect Failed' error, verify the motor was not moving at the start of blade detection, verify the correct number of blades setting, and verify motor parameters.
What does 'Communication Buffer Full Warning' mean for my MacroAir Technologies Fan?
If your MacroAir Technologies Fan displays a 'Communication Buffer Full Warning', verify the MODBUS baud rate, MODBUS wiring, and check for noise on the comms line.
What does 'Fire Disconnect' mean on my MacroAir Technologies AirVolution 550 Fan, and how do I resolve it?
If your MacroAir Technologies Fan displays 'Fire Disconnect', verify the fire disconnect is not asserted, verify the wiring is open or short as required, and verify the correct value is loaded into the fire disconnect register. It could also be due to a firmware update with no setting (blank NVM location).
What does 'Keep-Alive Timeout' mean for my MacroAir Technologies Fan, and how do I fix it?
If your MacroAir Technologies Fan displays a 'Keep-Alive Timeout', verify the building automation settings, check the time setting on the controller, and inspect the wiring for intermittence. This could also be due to a MODBUS transaction on analog control for FW 8599, SFTC-2411-01 v1.1 and earlier.
What does 'Phase Current Following Error' mean for my MacroAir Technologies Fan?
If your MacroAir Technologies Fan displays a 'Phase Current Following Error', verify the blade setting, check if the fan hits an obstruction, and verify the motor parameters. Perform a power calibration.
Why is my MacroAir Technologies Fan displaying a 'Heatsink Temperature High Warning' and running slower?
If your MacroAir Technologies Fan displays a 'Heatsink Temperature High Warning' and runs slower, it could be due to the operating ambient temperature being exceeded, blade end caps having no or poor venting, or a gap between the blade root and cover being too big.
Why is my MacroAir Technologies Fan displaying a 'Motor Temperature High Warning' and running slower?
If your MacroAir Technologies Fan displays a 'Motor Temperature High Warning' and runs slower, it may be due to the operating ambient temperature being exceeded or the motor thermistor being out of specification and/or damaged.
What does it mean if my MacroAir Technologies AirVolution 550 displays a 'Phase Current A High Fault'?
If your MacroAir Technologies Fan displays a 'Phase Current A High Fault' accompanied by current not regulating, grunting or vibration sounds, or sudden shutdowns, verify the motor parameters. Perform a power calibration. Returning to the factory may be necessary if there is a damaged drive, motor short/bad wiring, or the drive is in danger of permanent damage.
What to do if my MacroAir Technologies AirVolution 550 Fan changes speed suddenly?
If your MacroAir Technologies Fan experiences a sudden change of speed, verify that there are no obstructions in the path of the fan blades. Also, verify the motor parameters and perform a power calibration. This issue could stem from startup oscillation.
