Wall Controller Operation (cont.)
Understanding and clearing fan faults
To reset the fan controller,
press the STOP/RESET button (after the condition that induced the fault has been cleared).
External faults
EF or “External Fault” is displayed when the fan has stopped due to an alarm condition. EF also displays if the
user has interfaced the fan system with other equipment requiring fan shutdown, such as an ESFR system.
Internal faults
All other error codes are considered “Internal faults.” These codes are specific to problems associated with the
fan controller or motor. For example, the error code for “input power phase loss” is shown on the left. For a full
list of error codes and their meanings, see “Fan Error Codes” on page 47.
Programming and parameter changes
CAUTION: Under no circumstances should an operator attempt to alter the programming of the fan’s controller without
the assistance of an authorized Big Ass Fans installer, the Big Ass Fans Customer Service Department, or the Big Ass
Fans Engineering Department.
To access parameters and make changes to the behavior of the fan system,
press the PROG/DATA button. If
this button is pushed inadvertently, exit programming mode by pressing the MODE button twice to return to the normal
operational screen.
Note: To access the PROG/DATA button on the controller, the controller cover must be removed.
