Please make sure the
PTO & MONITOR OFF
Locate the 2 lights on the individual blue wing sensors.
Green light = 24vdc power to Sensor
Amber lights = signal being sent to comp.
(Sensor light will not show green on the monitor.)

1. Look at the sensor, check to make sure the
   amber light is on. If it is, the corresponding wing
   light on the Zapper monitor should be Green.
   If the sensors amber light is on and no green light
   on monitor check wires/pins.

2. If the sensors amber light is not on with wings
   down in field position check the sensor
   placement. Moving sensor closer to the center of
   the boom increases sensitivity, moving it closer
   to wing hinge point decreases sensitivity.
   (Sensor light will not go red on monitor)
3. Make sure the wing cylinder stops are down
   (field mode) contacting the cylinder rams.
4. Raise the booms until they contact the cylinder
   stops. Lock valve to keep wings up while working
   on the boom.

5. Check to make sure both wing Sensor amber
   lights are OFF. If either amber light is on, check
   for hoses etc… that are in close proximity to the
   sensor. Move them away from the Sensor and see
   if the amber light goes off when they are moved.
   If nothing is close to the sensor try unplugging it
   and check the monitor for red/green lights.

6. If the amber light is off the corresponding wing
   light on the Zapper monitor should be Red. If the
   amber light is off but the monitor shows green
   check wiring or Sensor.

7. A spare speed sensor can be plugged into the
   wing port on the harness for testing purposes. If
   the sensor lights are on the corresponding
   monitor light should be green.
