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.
