7.2.2.7
DIGITAL INPUT ACTIVE LEVEL
The digital control inputs may be either Active Low or Active High. The software is factory configured for Active
Low inputs. See Section 5.2 and Figure 4.
7.2.2.8
INITIAL SCREEN
The first screen after power-up is the "Operator Loop" screen. This parameter allows the initial power-up screen to
be changed to either the "Position" screen, Section 7.2.1.1 or the "Output Level" screen, Section 7.2.1.3.
7.2.2.9
NUMERIC UPDATE RATE
This parameter controls the filtering for the numeric actual position and the actual output displays. Default values
work well in most applications.
7.2.2.10
BAR GRAPH UPDATE RATE
This parameter controls the filtering for the bar graph actual position and the actual output displays. Default values
work well in most applications.
7.2.2.11
SCREEN CONTRAST
This screen allows adjustment of the screen contrast. See Section 10.1, General Problems, when screen shows no
characters.

DANCER INPUT SETUP (REQUIRED)
7.3.1
Setup DFP or DFP-2
7.3.1.1
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.
7.3.1.2
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.
7.3.1.3
Check DFP or DFP-2 voltage
Verify the dancer voltage between Term. 38 and Term. 39 matches the voltage change with dancer movement as
shown in Figure 12. If the dancer voltage is opposite that shown in the figure, simply swap the wires on Term. 39
and Term. 26. This will reverse the dancer voltage change.
7.4
DANCER CALIBRATION (REQUIRED)
Navigate to the
Cal Dancer
menu
.
Press the
arrow and the screen should show:
This screen allows the selection for calibrating either the Dancer Input or the Position Setpoint input. The input
from the dancer position sensor and from the position setpoint should both be calibrated. Both are calibrated in the
same way. Press either the
or
key to begin a calibration.
