  • Page 7 RDA 500-800 S INTRODUCTION Väderstad Rapid A 500-800 S is a high-capacity cultivation drill. The Rapid drills can be used under a large variety of conditions, from "direct drilling" to sowing straight after the plough. This versatility is made possible by the drill's coulter system design and its unique depth control system, amongst other features.

    RDA 500-800 S Adjusting sowing depth 3.7.1 Adjusting the master and slave system Figure 3.18 The sowing depth of the drill is controlled by three hydraulic rams connected in series in a so- called master and slave system. Before using the drill for the first time, the rams must be bled and their position zeroed in relation to each other thus: Raise the drill to its topmost position so that all hydraulic rams are fully extended.

  • Page 32: Adjusting Weight Transfer

    Instructions and settings Adjusting weight transfer Figure 3.19 Figure 3.20 The weight transfer system is usually preset to 30-50 bar. This pressure works well under most conditions and does not normally require adjustment.

    RDA 500-800 S Troubleshooting General information on troubleshooting Many of the functions of the drill are controlled by a series of electrical, hydraulic and mechanical components. A good way to exclude many of the sources of faults from the start is to first deter- mine whether the fault is electrical.
  • Page 90 Troubleshooting 6.1.3 Hydraulic electric valves Figure 6.1 Figure 6.2 An electric valve contains a coil that operates as an electromagnet when current is fed to the valve. Do as follows to check whether the valve receives current: The LED on the connector lights and the coil becomes warm after a few minutes. Also, the nut on the top of the valve becomes magnetic.
  • Page 91 RDA 500-800 S 6.1.4 Magnetic switch Figure 6.3 A reed switch is a switch (or a sensor) that reacts to a magnetic field. Inside the reed switch is a glass tube containing two metal reeds that attract to each other when subjected to a magnetic field from a magnet.

    Troubleshooting Troubleshooting chart The Control Station does not op- erate when the main switch is switched on! - See ”6.1.1 Electric fault” on page 89. The bout marker(s) cannot be unfolded! - Check according to ”6.1.1 Electric fault” on page 89. - Check according to ”6.1.2 Hydraulic fault”...
  • Page 93 RDA 500-800 S Unintentional very slow unfold- ing of retracted bout marker(s)! - Check that the indicator lamp of the bout marker is not lit on the Control Station. - Check that the electric valve (A) or (B) of the bout marker does not receive current.
  • Page 94 Troubleshooting The drill can be raised although the lift stop is engaged! - Check whether the magnetic valve (C) on the valve block receives current. See Hydraulic electric valves under ”6.1.3 Hydraulic electric valves” on page 90. - Check the low-lift switch as explained above. If the lift stop valve does not receive - See ”6.1.1 Electric fault”...
  • Page 95 RDA 500-800 S Leakage from the shaft seal on - Leakage from the shaft seal of the hydraulic motor the fan's hydraulic motor! may be caused by: - Damage caused during assembly. - Wear due to dirt. - Wear due to too high pressure in the drain line. - A damaged seal caused by very high pressure in the drain line.
  • Page 96 Troubleshooting The Control Station generates a seed box drive alarm! - Check whether the drive wheel has been lowered and In case of doubtful drive: drives against the ground. - Check the transmission between the drive wheel and the seed boxes. - Check the sensor operation.
  • Page 97 RDA 500-800 S The drill is sinking, i.e. it drills deeper than the set drilling depth! - Is the O-ring on the master ram's cut-off valve dam- aged or missing? See ”5.14 Changing the valve seals on the master ram” on page 84. - Does the stop bolt touch the bottom at the rod's upper end? In this case the spring has been compressed or is damaged.

  • Page 98: Alarm List

    Troubleshooting Alarm list 2 Low seed level, right-hand side. - Check the seed level of the seed hopper. If there is seed in the seed hopper: - The sensitivity of the sensor has been incorrectly set. 3 Low seed level, left-hand side. - See alarm no.
  • Page 99 RDA 500-800 S 18 Seed fan, low rpm. - Check that the hydraulic hoses have been correctly connected to the tractor. - Check whether the hydraulic oil flow from the tractor has been correctly set. - Check the alarm time limits that were programmed into the Control Station.
  • Page 100 Troubleshooting 25 Seed box clutch, right-hand side. - This alarm is generated when seed shut-off on the right side does not operate. - Check the cable, switch and connection of the mag- netic clutch in the right seed box. An LED on the seed box switch lights when the clutch receives current.
  • Page 101 RDA 500-800 S 41 Hydraulic motor, seed output. - Is the hydraulic oil flow sufficient? Does the seed out- put fan start? - Check whether the seed boxes can rotate by hand. - Check the cable, connector and connection of the sen- sor.
