STEP
Making the Connections
Now, extend the cable leads to the Flow meter or Pressure Sensor, and Wheel
Sensor or Radar Sensor to the furthest component. Select the appropriate lead
and connect to this component. Run the cable to the other component, taking
care to safely secure the cable along the route. Refer to the diagram on page 10.
Repeat this procedure with the cable leads to the Pressure Regulating Valve
and the Boom Control Valves. Refer to the chart below when attaching the boom
section wires.T-tap connectors must be attached to the +12vDc and ground
wires to connect them to the boom control valves (when using ball valves), which
should be evenly distributed across the two.
If both the flow meter and pressure transducer are not used simultaneously, there
will be one extra connection on the cable. Simply tie this part of the cable back as
it will not be used.
When all connections have been made, connect the large plug into the side of
the Control Console.
You are now ready to begin the programming
of the TeeJet Model 844 Sprayer Control.
Valves requiring DPDT switches are not compatible with the 844.
Note: The 844 is designed to handle a maximum of 4 amps per boom section.
