Analog Outputs Page Description
(continued)
Each Analog Output has 32 setpoint pairs (x,y values). In this example using four x,y
pairs, 2.362” and 1.0% are used for the setpoint of position 1. This means that the air
will be at 1% after 2.362”. If the air is making a transition from one level to another
over a length, the points in between the two setpoints are calculated. Using the previ-
ous example, position 1 is at 1% and position 2 is at 2%. The change of air will
occur over 0.787”, at the midway point (0.3935”) the output of the air will be at
1.5%.
To adjust the length and air pressure used for each setpoint:
1
Press the Length window. A pop-up keyboard appears.
2
Enter new length to the next position. Each length is relative to the previous
length.
3
Press “Enter”. The pop-up keyboard is removed.
4
Press the Percentage window. A pop-up keyboard appears.
5
Enter new amount of air pressure to be used (0-100%), and press “Enter”.
Use the “Up” and “Down” arrow buttons to move up and down the preset list.
Typically when using outputs to control air pressure, four setpoints should be used to
control the amount the profile tubing will expand and contract.
Each setpoint will be display on the graph at the top of the Analog Output Page.
Presets for Analog 1 will be displayed with a red line and presets for Analog 2 will
be displayed with a yellow line.
