I have connected the RiteHeight wiring to my solenoids, but the booms will not move or will only move down. How can I fix this?
First, check your wiring using the Test: Valve Wiring screen. For example, when you press your sprayer’s left up switch, the display should show LUP.
If all functions show correct wiring, but Test: Try Valves cannot move the booms, you may have an open center or load sensing hydraulic system that uses a Master valve (also known as a dump valve, jam valve, or unload valve).
You need to connect the RiteHeight MASTER output in the junction box to the Master valve using the WA0226 Extra Solenoids cable and enable the MASTER output in the Machine Setup menu.
The Master valve is usually located at the very end of the hydraulic manifold and has a single solenoid that usually looks different from the other solenoids on the manifold. The Master valve is located under the tank on John Deere sprayers, on a small square manifold with two solenoids (the Master solenoid is the smaller solenoid of the two).
Where can I find the up and down valve solenoids on a pull-type sprayer?
Many pull-type sprayers do not have separate up and down solenoids for each cylinder. Instead, they have only one solenoid for each cylinder and use a Directional valve to control the direction of oil flow (into or out of the cylinder). In the Machine Setup menu, enable the DIR. VALVE. Use the WA0226 Extra Solenoids cable to connect the DIR output of the RiteHeight junction box to the Directional Valve on your sprayer. The Directional Valve is usually located at one end of the hydraulic manifold and usually looks different from the other solenoids.
The self-Cal does not move the booms at all or only moves them down. How do I fix it?
Use the Test: Try the Valves option to test whether the RiteHeight system can move each boom up and down.
If not, use Test: Valve Wiring to check if the connections to the solenoids are correct. For example, when you press your sprayer’s left up switch, the display should show LUP.
What do I do if the booms are hunting (constantly going up and down instead of settling down)?
If you experience this, please check the following:
– First, make sure you have run the Self-Cal procedure, as described in the manual. Ensure the oil is at full pressure and operating temperature, and the sensors are pointed at flat ground (a gravel yard is ideal). On a pull-type sprayer, make sure the tractor’s remote flow rate is the same during Self-Cal as when you are spraying.
– Make sure the Deadband is not set too small. A value of 6.0″ (15 cm) generally works well.
– Try changing the Motion Control settings to a slower setting. Start by adjusting the LEFT DOWN and RIGHT DOWN settings first.
– Check the Quick Raise Height setting and ensure it is not set too close to the target height.
– You can help stabilize boom control operation by minimizing the uncontrolled motion of the boom. Ensure that any shock absorbers are in good condition, and replace them if necessary. If the boom has an auto-levelling feature, adjust it for minimum action or consider locking it out completely.
– If your boom hydraulics are very fast, it may be necessary to install flow restrictors. This reduces the hydraulic flow rate, helping to achieve stable control. You can use one-way flow restrictors to reduce the downward speed of the boom hydraulics but maintain fast upward speed.
The booms are not lifting fast enough – how can I improve the speed?
If the RiteHeight system is not raising the booms fast enough to keep them from hitting the ground, try the following:
– Reducing the CONFIG Delay for Up setting will cause the RiteHeight system to lift the booms more quickly.
– Setting the CONFIG Quick Raise Height to 10 inches (25 cm) below the target height will cause the RiteHeight system to lift the boom immediately when it gets too close to the ground, skipping the usual Delay for Up time.
– Avoid setting the MOTION CONTROL settings for LEFT UP and RIGHT UP too slow. Usually, the default value of 3 works well.
– The RiteHeight system can only move the booms as fast as the hydraulics will go. For a pull-type sprayer, try increasing the tractor’s remote flow rate — but remember to repeat the Self-Cal procedure when you change the flow rate. On some sprayers, restrictor orifices are installed in the lines to the boom lift cylinders. Removing these orifices or replacing them with less restrictive orifices can speed up boom movement.
– If the booms move faster going down than up, consider installing one-way flow restrictors to reduce downward speed but maintain full upward speed.
What do I do if one or more of my sensor readings is showing –?
This indicates the sensor is working but is not getting a reading. This can happen if the boom is very high above the ground. If you are seeing — all the time for a sensor, check for dirt or debris on the sensor. Also, check the sensor cable to see if it has been pinched or damaged.
What do I do if one or more of my sensor readings is showing XX?
This indicates the sensor is not functioning. Check the sensor cable to see if it has been pinched or damaged. If you see no apparent problems, you can try swapping the sensor with another to see if it works there.
What does the error message “Comm. Error” mean?
This message indicates that the console (box with keypad and display) in the cab cannot communicate with the junction box (square box where the sensor and solenoid cables connect).
Check the WA1055 (or RH229) cable to see if it has been pinched or damaged.
Then check inside the junction box to ensure the WA1055 cable is wired correctly (wiring instructions are inside the junction box lid).
