- Page 4 IMED’s Pitch Angle Indicator (PAI) displays the propeller pitch angle in real time. The design is microcontroller based which makes it easy to configure and eliminates the need for any trim pots, etc. IMED’s PAI will work directly off most existing pitch feedback units, basically any potentiometer from 1kΩ...
- Page 5 No more fine tuning or offset adjustments. Simple setup process derives all required parameters. Intuitive adjustment of sensitivity. The standalone version has backlighting included for best night time visibility. Brightness is set automatically. Figure 1. IMED PAI User Interface...
- Page 6 As the pitch angle changes, the LED display updates according to the LED Operation angle. When the pitch angle is less than 0°, the red ‘Astern’ section of the PAI is active. When the pitch angle is 0°, only the Neutral LED is active.
- Page 7 For best performance, the potentiometer’s movement should have a Resolution large span from Astern to Feather i.e. having a 10 turn, 10 kΩ pot, which only does 1 full turn over the full span of the pitch will have less resolution than that of a single turn, 10 KΩ...

- Page 9 The PAI has three pushbuttons labelled P/A (Pitch at Astern), C/N (Pitch at Neutral) and S/F (Pitch at Feather). These buttons are used to setup the PAI. A specific setup procedure must be followed to setup the PAI for use. The Receipt LED is located at the back of the PAI on the bottom-left side of the pushbuttons.
- Page 10 I M E D P i t c h A n g l e I n d i c a t o r v 2 . 0 The first step of the setup procedure is to configure the board using the DIP switch 4 DIP switches.
- Page 11 For the PAI to operate, five points need to be programmed in order to calculate the required offset and gain for the scale. The angle indicator will also negate the signal automatically if required, based on these two inputs. The points are: Astern, Neutral, Point ‘A’, Ahead and Feather. Each point is illustrated in Figure 7.

- Page 13 Display current It is possible to display the current DIP switch configuration. To do so, press and hold the P/A and S/F button together. DIP switch setting Receipt LED ( The Receipt LED will start indicating the state of each of the 4 DIP switches by blinking green a number of times followed by red once for OFF or twice for ON.

- Page 15 If the PAI does not respond to pitch movement, confirm the wiring No response or only neutral LED matches the wiring diagram on Page 5. If the display only shows the neutral position and does not respond to pitch movement, check the Receipt LED D3 on the back of the PCB for other errors Receipt LED This means that the unit is currently configured to be a slave (using DIP...
