Keypad Err

Does your Basic 6 or Powerfoil 8 fan keypad have a red LCD display that flashes “Err” when the Run button is pressed or when you try to adjust the speed? A parameter may have been accidentally mis-set. Try these troubleshooting suggestions.

1. Press the Stop button first. Then locate and press the “M” button on the keypad to enter the parameter menu for the fan’s “brain,” called a variable frequency drive (VFD).
2. For “Err” on Run, use the arrow buttons to navigate to P100 on the display, press M to view that parameter’s current setting, and change that setting back to “02” to activate the remote keypad’s Run button as the “Start Control Source.” Press M to save the change, and then try the Run button again.
3. For “Err” when adjusting the speed, press the “M” button and use the arrow buttons to navigate to P101 on the display, press M to view its current setting, and change that setting back to “00” to activate the keypad’s up/down arrow buttons as the “Speed Control Source.” Press M to save the change, and then try starting the fan and adjusting its speed again.
4. If other parameters in the menu were also mis-set, fan performance could be negatively impacted. Contact Customer Support if the above steps do not resolve the issue.
