Changing the fan speed
The LOC indicator must be illuminated to adjust fan speed, which can be performed when the fan is stopped or
running.
To change the fan speed,
press the UP and DOWN arrow buttons. The fan speed can
be adjusted regardless of what is visible on the LED display, with the exception of the
Memory Read/Write screen. When one of the direction keys is pressed, the current
display mode is forced to change to the Fan Freq. Command screen as shown below.
Note: To accelerate this process, press either the LEFT or RIGHT arrow button to select which digit is controlled by
the UP and DOWN buttons. The button cover must be removed (if used) in order to access the LEFT and RIGHT arrow
buttons.
To start the fan,
press the RUN button on the auxiliary controller. When the RUN button is pressed,
the STOP LED extinguishes and the RUN LED illuminates while the fan accelerates to the commanded
speed.
To stop the fan,
press the STOP/RESET button. The RUN LED will flash, indicating that the fan has
accepted the command, and the STOP LED will illuminate.
Proper fan rotation is initially set at the factory.
To reverse the rotation of the fan,
press the FWD/REV
button. The fan does not have to be stopped in order to perform this action. When pressed while the
fan is running, the FWD or REV LED will flash (current direction), indicating a pending change in fan
direction.
AUXILIARY CONTROLLER OPERATION
Upon initial power-up of the fan, the auxiliary controller appears as shown on the
right. The auxiliary controller is programmed to show the fan’s current running speed
in RPM on the LED display. The display also indicates if the fan is stopped (STOP), set
to run forward (FWD), or is set to respond to a remote control source (REM) such as an
Energy Management System or Building Automation System.
Other main LED display modes include Motor Current, Memory Status, Motor Command
Frequency, and Motor Actual Frequency. Useful indicators of fan status on the auxiliary
controller are RUN/STOP, JOG, FWD/REV direction, and External or Local Control.
To operate the fan from the auxiliary controller,
press the LOCAL/REM button to make
sure that the LOC indicator is illuminated. The RUN, STOP, and FWD/REV buttons are
functional only when the LOC indicator is illuminated.
Note: To access the LOCAL/REM
button on the controller, the controller's button cover must be removed (if used).
