Dancer  Applications 

 
6.1  

Electrical Connections 

 
Figure 7 shows the connections that are required for the basic dancer system.  They are: 

115vac power input 
90 vdc output for clutch / brake 
DFP or DFP-2 dancer position sensor 
Install jumper between terminals 20 and 21. 

 

The clutch / brake output and the remote meter output are not isolated from the AC line and must not be 

referenced to ground.  The control inputs are isolated and may be ground referenced.

Sensor Setup 

 

The DFP or DFP-2 position sensor should be at the center of rotation when the dancer is halfway 

through its travel.  This is an approximate adjustment and is intended to center the sensor position to 

allow maximum rotation in both directions during operation. 

 

DFP 

 

Install the DFP sensor so that its keyway is pointing towards the top cover when the dancer is half way 

through its travel.  This is an approximate adjustment, and is intended to center the sensor position to 

allow maximum rotation in both directions during operation. 

 

DFP-2 

 

To find the electrical center point of pot rotation, use a digital multimeter type ohm meter to measure from 

the white wire (wiper), to the red or black wire.  Turn the potentiometer shaft until the meter reads 500 

ohm.  Install the DFP-2 sensor so that at the 500 ohm meter reading, the dancer is halfway through its 

travel.
