Try to manoeuvre the function manually by pressing the point of a screwdriver into the end of the valve housing At the same time the corresponding switch on the control unit has to be operated to get electric power to the master valve If the function is working again after this the mote has been pushed out in the oil system and the machine can be operated normally again MASTER VALVE To get anything to work the master valve pos 7 fig 14 1 must have electric power If there is no power supply to this valve the oil goes straight back to the tank and nothing happens For tractors with closed centre hydraulic the closed centre valve pos 8 fig 14 1 always have electric power See also chapter 14 1 and 16 4 1 EMERGENCY STOP The emergency stop is constructed so that the electric circuit must be closed to be able to start the machine As soon as it s broken the machine will stop This is shown on the control units display by three points lighting up See chapter 7 10 When the emergency stop is activated there shall be measured 4 volts over the emergency stop switch Emergency stop see chapter 1 0 42 17 0 TROUBLE SHOOTING In this chapter we assume that the descriptions in chapter 16 0 are controlled and in order 17 1 MACHINE DOES NOT FUNCTION a b Even if the gauge shows enough pressure there is no reaction in the machine The reason could be that one or both of the quick cou

THE WRAPPING ARM IS ROTATING BUT THE ROLLERS ARE NOT Check first that the flow control valve for rollers is not closed Fig 9 1 THE CUTTER DOES NOT LEAVE THE FILM WHEN THE MACHINE IS TESTED WITHOUT LOAD The reason for this is that when the cutter is closed with maximum pressure it might be difficult to obtain sufficient pressure to open the piloted non return valve pos 9 fig 14 2 if the machine is empty i e wrapping arm and rollers unloaded This will not happen while wrapping with a bale on the machine If this should occur when testing without a bale it can be avoided by not having the cutter closed with full pressure Give a short push on control no 5 CUTTER up enough to release some of the pressure ONLY FOR AUTO WRAP 1504 EH a Power at only one of the rollers while wrapping The reason to this might be that the piloted non return valve pos 2 fig 15 1 does not close Replace it with a new one b Power at both rollers while loading the bale The piloted non return valve pos 2 fig 15 1 does not open Replace Emergency stop see chapter 1 0 44 HYDRAULIC CHART NORSE AUTO WRAP 1500 EH 1 OILFILTER Pami COUPLING 8 1 WRAPPING ARM MOTOR WRAPPING ARM SPEED Emergency stop see chapter 1 0 WIDTH CT IN OUT 45 HYDRAULIC CHART NO
