Electrical connections
Connections required for the basic follower arm system:
115 VAC power input
90 VDC output for clutch/brake
DFP or DFP-2 roll diameter sensor
10kΩ tension potentiometer
The clutch/brake output and the remote meter output are not
isolated from the AC line and must not be ground referenced.
The control inputs are isolated and may be ground referenced.
See Figure 4.
Sensor setup
The DFP or DFP-2 position sensor should be at the center of
rotation when the follower arm 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. (See Figure 4.)
