  • Page 14: Hydraulic Flow Adjustment

    INITIAL START UP Oil flow adjustment for the booms For adequate operation, it is necessary to adjust the hydraulic flow of the tractor. The hydraulic distributor (hydraulic block) oil flow must be adjusted to 5 gpm. To do this, complete the following steps: IMPORTANT ! The oil distributor feeding the hydraulic block must be adjustable. If this is not the case, check with the tractor manufacturer that the flow is between 4 and 6 gpm and do not complete the following steps. 1. Take the 5 gpm hydraulic velocity fuse with BLACK anti-dust caps and connect it between the #2 distributor of the tractor and the boom function’s hydraulic block (figure 21). It is recommended to use the #2 distributor to feed the hydraulic block.

  • Page 15: Hydraulic System Purge

    INITIAL START UP 6. Continue to increase very slowly the flow until the pressure drops suddenly to 0 psi and the error message “hydraulic pressure too low” appears (figure 23). In addition to the message, there will be an alarm that will sound. (Do not increase the hydraulic flow from now on). The flow has now reached 5 gpm. On the majority of tractors, the triggering of the circuit Hydraulic pressure too low. Check velocity fuse will happen when the indicated pressure is at about 180 psi. hydraulic outlet. 7. If the flow is disturbed during operation or if there is a change in tractor, follow these steps again. 8. Remove the velocity fuse installed in step 1. Figure 23 Additional notes on hydraulic oil supply: - Hydraulic oil flow must be controlled by the tractor. Installation of an external valve to control the flow would result in overheating of hydraulic oil. - Use of hydraulic oil other than the one recommended by the tractor manufacturer could cause overheating of hydraulic oil. - A worn distributor or worn outlet coupler would create more restriction to the passage of oil, causing a higher return pressure and producing more heat. - A dirty hydraulic oil filter causes overheating of the oil. - When manufactured, the sprayer’s hydraulic manifold has been adjusted for open circuit tractors. That setting work as well with closed circuit tractors as with open circuit ones. Do not modify manifold adjustments before contacting the manufacturer. Hydraulic system purge Before using the system for the first time, you must make sure that there is no air in the hydraulic circuit. The following procedure explains how to purge the system. Purge the system before using your sprayer for the first time, at the beginning of each spraying season and also after maintenance or repair works have been performed on the sprayer hydraulic system.

  • Page 41: Example Of Trouble Shooting

    TROUBLE SHOOTING Example of trouble shooting For this example, we will suppose that the problem is that the centre part of the boom refuses to move. All other cylinders are moving normally. The problem could be caused by the console buttons, by the control board, by a valve cable, by a valve coil, by a valve or by a cylinder. Instead of replacing all parts that could be defective until it works, you will try to find exactly which part is defective, and then replace the right part. 1- First, test the console buttons. From the main screen, go into Configuration, then into Diagnostics and then into Buttons. Press CENTER buttons, up and down. If corresponding squares do not light, buttons are defective, have the console repaired. If squares light, buttons are working properly, go to the next step. 2- We will now have to go behind the sprayer. Unscrew a little the 2 knobs of the console holder and slide the console out of its holder. Disconnect the console plug and go behind the sprayer, near the control box. Disconnect the cable from outlet #1 (first one from the left) and plug in its place the console plug. You will now be able to control the system from behind the sprayer. Do not forget to plug back the cable that was in outlet #1 when you bring back the console inside the tractor cab. 3- Open the control box. In the upper left corner, LED5 is already lit, proving that the system is powered. More on the right, LED18 is flashing, proving that the console is communicating with the control box. 4- Refer to Function tables in the previous Outputs section. According to the tables, when raising the center, LED17 and LED20 should light, and when lowering, LED17, LED15 and LED20 should light. 5- As Dump valve LED17 and Directional valve LED15 are used for many other functions that are working normally, we already know that those valves are working normally. But function for Center valve LED20 could be defective. 6- Push CENTER UP button and check if LED17 and LED20 light on. Push also CENTER DOWN button and check for LED17, LED15 and LED20. If one of the LED does not light when it should, the control board is defective. Have the control box repaired. If the LED light like they should, the control box is correct, we now know that the problem is at the outlet of the control box. 7- Because the Dump valve and the Directional valve are used in other functions that run normally, we know that those valves are working correctly. But Center valve has to be checked. 8- Referring to drawings in the manual, Center valve is identified and is the valve #C4. Manually activate Center valve LED20 according to instructions of previous Outputs section or ask somebody to press and maintain the CENTER UP or CENTER DOWN button.
