Note: Internally, the Speed Controller provides 240VAC 3 phase at 8kHz switching frequency to the motor.
Speed Dial Wiring Diagrams
Mounted Speed Dial
– (See Figure 4) Standard potentiometer
speed dial is mounted and wired at the factory.
For field replacement: Connect the Speed Control Potentiometer to
the motor control as follows:
a. Connect one end of 10K Potentiometer to P10-1 (24VDC).
b. Connect center (wiper) of Potentiometer to P10-2 (Analog
Input)
c. Connect other end of Potentiometer to P10-3 (DGND).
Remote Speed Dial**
– (See Figure 5 & 5A) Factory mounted
Molex receptacle allows a quick connection to remote potentiometer
speed dial. The potentiometer dial can be mounted up to 100 ft
from fan using additional wire by others.*** Speed B on box is not
used for single speed selection and will not have a dial.
Dual Speed Dial**
– (See Figure 5 & 5B) Factory mounted Molex
receptacle that allows a quick connection to Dual Potentiometer
Speed Dial. The supplied unmounted toggle switch will select the
Low (LO) or High (HI) speed on the speed controllers based on the
dial settings. Toggle switch and mounting plate fit in a standard
gang box and wired to Dual Potentiometer Speed Dial. The speed
dial can be mounted up to 100 ft from fan using additional wire by
others.***
Building Control 0-10VDC Wire Kit
– (See Figure 5 & 5C)
Factory mounted Molex receptacle that allows a quick connection
to supplied 2 wire connector (wires are 3” long).
**
Disconnects and Speed Dials are available as mounted on
certain fan models and will be wired to motor, for more information
see descriptions on submittals for these items weather they are
mounted, not mounted or not available
***
For extended wiring up to 100 Feet you will need (1) Receptacle
Molex 3 1396-R4 with 3 Pin Female Molex 02-09-1119 and (1) Plug
Molex 3 Pin 1396-P1 with Pin Male Molex 02-09-2118 not provided.
