4. R PNP OUTPUTS The opto interrupters require an external power supply to operate the LED lamps The sensor signals are powered through an additional two wires the red excitation and black ground wires ESD Circuit Protection and Cautions e Do not apply greater than 30 Volts to the outputs at any time e We suggest that you not mount the sensor until the proper grounding is available When you mount the sensor protect the signal wires and connect the ground first After connecting to ground attach the signal wires from the sensor e There are internal reverse protection diodes on each output If the outputs are pulled below ground the diodes will clamp the output to ground e Do not apply constant reverse voltages to the outputs The internal diodes are intended only to protect the sensor outputs from transient reverse voltages for example the inductive turn off spike caused by driving reed relay coils directly from the yaw vane s outputs S3682 FG3579manual doc 1 Rev 1 12 28 2004 Interpreting Output Signals 2 Channels The diagrams and table below indicate when each of the two outputs is active 1 or inactive 0 for each relative direction the nose is pointing For example if the vane nose is pointing 35 degrees relative to the base the V90 output green wire will become active VANE NOSE 0 NUT HOLE END OF BASE BOLT AXIS WN v90 ACTIVE 270 sf 90 a ACTIVE SLOT BOLT HEAD VANE SHOWN E
