SPEED CONTROL STATION
Figure 14
The fan control station is provided in a 4.75 x
4.75 x 1.75 in. (120 x 120 x 45 mm) enclosure
suitable for mounting on a wall or column. The
face of the controller may be removed and
mounted flush in a standard double gang wall
box.
The control station uses low voltage (24 VDC)
control. A 7-conductor cable (24 AWG min/
0.5 mm diameter min, 0.2 mm
^2 min) connects
the control station to the variable-frequency
drive (VFD) enclosure. CAT5 is acceptable for
this run (500 ft [152 m] maximum length).
A power button is provided to turn the fan on
and off.
The turtle and rabbit buttons incrementally
decrease and increase fan speed.
Pressing the direction button causes the fan to
change direction.
A ring of LEDs in the FANS logo provides a
visual indication of fan speed (1 LED = slowest,
7 LEDs = fastest).
After turning the power on, or a direction
change, the LEDs flash to indicate direction.
Standing below the fan, looking up, the blades
should turn clockwise (forward) when the LEDs
flash in a clockwise pattern. If the rotation is
counterclockwise, disconnect power to the
control box and swap two of the three motor
wires (terminals U, V, W) to reverse fan
direction.
The VFD is factory-set to linearly increase fan
speed to satisfy the majority of applications.
By changing parameters in the drive, the speed
curve can be modified for specific applications.
