Page 3: Introduction
AUTO WRAP 1200 EH is designed to wrap bales of grass, hey or straw, with nominal diameter of 3½ - 5½ ft. (110-170cm), and weights up to 1760 lbs. (800kg). The machine is developed and has been improved since the beginning in 1986, and is now a very reliable and safe machine with high security built in.
Page 4: Safety Precautions
(See chapter 2.5). EMERGENCY STOP. Auto wrap 1200 EH is equipped with a so-called emergency stop on the wrapping arm. This device stops all functions momentarily, but is per definition not an emergency stop, because it does not shut down the inputs.
Page 5 Fig. 2-2 DANGEROUS AREAS. TELLEFSDAL A.S has given the safety to the operator the highest priority, but it is still impossible to secure oneself of every danger area on the machine. Therefore we will now go through some of the dangers that can occur when using the Auto Wrap balewrapper.
Page 6 Fig. 2-3 Fig. 2-4 SQUEEZE DANGER BETWEEN THE ROLLERS AND THE MAIN FRAME. During the wrapping process the bale rotates on two rollers. These two rollers rotate around the square pipe they are mounted on. Between the roller and the square pipe there is a squeeze danger for the fingers.
Page 7 Fig. 2-5 Fig. 2-6 2.6 LOCKING THE WRAPPING ARM. When the machine is not in use, make sure the locking bolt for the wrapping arm is mounted, and that the secure pin is fitted. If the bolt is not mounted, the wrapping arm and/or the machine could be damaged during transport.
Page 8: General Information On Balewrapping
GENERAL INFORMATION ON BALE WRAPPING. THE PRINCIPLE. The advantages of round bale ensilage are many, and include fewer feed units, a flexible harvesting system, large capacity and the possibility of selling feed units. In principle, the same fermentation processes occur whether the fodder is placed in a silo or pressed into bales and packed in plastic, i.e.
Page 9 STORAGE LOCATION. Care should be taken in finding a suitable location for the storage of bales. The storage location should preferably be prepared before the bales are laid out. An elevation close to well-drained roads is recommended. If the wrapped bales are simply placed on stubble there is a danger of the plastic being pierced.
Page 10: Setting Up / Mounting Of The Machine
THREE POINT LINKAGE. AUTO WRAP 1200 EH is intended for rear mounting to the three point linkage, category 2. With considering of transportation are not the three point brackets mounted on the machine when it leaves the factory.
Page 11 Fig. 4-2 ELECTRIC CONNECTION. The electric supply for the machine's remote control and electro-hydraulic components must come directly from the tractors' 12 volt battery. The electric wires from the battery must have an area measurement of min. 2,5 mm Connection to other contacts on the tractor can cause risk of misfunctions, and is not to recommend. To secure the electric system against short-circuits there is an 10A fuse on the plus-leader, near to the battery pole.
Page 12 Fig. 4-3 Fig. 4-4 4.6 HYDRAULIC CONNECTION. The hydraulic hoses between machine and tractor are equipped with 1/2" ISO male quick-couplers. Discharge the oil pressure before you connect the oil hoses. Use the tractors' hydraulic lever. To make sure that the balewrapper works properly, the tractors' oil pressure has to be at least 180 bar.
Page 13 Fig. 4-5 4.8 CHECK LIST. Before using the machine it is recommended to follow this check list: Make it a habit to discharge the oil-pressure before connection or disconnection of the hydraulic hoses. (By operating the hydraulic control lever inside the tractor). (Use the tractors hydraulic control lever).
Page 14 Fig. 5-1 5.0 EMERGENCY STOP*. 5.1 The machine is equipped with a safety guard on the wrapping arm, and its operation must be tested before work itself is started. The safety guard is designed to stop the wrapping arm injuring operators or objects either when 5.2 starting up or when wrapping bales.
Page 15: Mounting Of Plastic Film
Fig. 6-1 Fig. 6-2 6.0 MOUNTING OF PLASTIC FILM. 6.1 When the plastic roll shall be mounted, you have to hold the prestretcher-rollers aside, Hold the rollers aside and put on the holding hook. (See fig. 6-1). 6.2 Place a reel of film on to the prestretcher's holding axle and put on the springloaded lock. 6.3 Pull the film between the rollers on the prestretcher in the direction of the arrow.
Page 16 CONTROL BOX The Tellefsdal control system is developed with the intension of assisting the operator to maintain full control of wrapping machine. The system provides for detailed instruction and massages via the 40 character alpha-numeric display, enabling the operator to monitor the operation of the wrapmachine at any inststant.
Page 17 When in “SET” mode, this is used to exit the “SET” mode in order to reenter the operative mode. Allows for adding extra film layers to the bale both during the wrapping cycle and at cycle restart. During the cycle one push will cause the required number of film layers to increase by 1, two pushes 2 additional layers etc.
Page 18 FUNCTION DESCRIPTION PRESELECT The AUTO switch will initiate the AUTOMATIC cycle. It may also be used to cut the cycle Wrap cycle short. Example: The wrapping cycle is set to 30 film layers. The operator wishes to complete the cycle and offload the bale using only the automatic facilities of the system.
Page 19 At the operator level there is a number of menus which enables the operator to perform various tests and adjustments to the machine operation. Should adjustments of parameters which are not accessable to the operator be required, please contact the TELLEFSDAL dealer or TELLEFSDAL A/S.

SETTING UP THE SYSTEM: All functions are preadjusted from the TELLEFSDAL factory and commonly the only adjustment which the operator needs to make, is the programmed number of film layers required. TYPICAL OPERATOR PROGRAMMATION. ( Standard for all machine models.) 1: Required number of film layers.

Page 22: Speed Setting Of The Wrapping Arm
Fig. 8-1 8.0 SPEED-SETTING OF THE WRAPPING ARM. 8.1 Start the tractor and let it run at approx. 1000 revolutions per minute. Lift the machine clear of the ground. The oil flow to the machine is adjusted by two control valves on the machines' "shoulders". 8.2 The control valve on the "shoulder"...
Page 23: Adjusting The Overlap
Fig. 9-1 Fig. 9-2 ADJUSTING THE OVERLAP. WRAPPING ARM SPEED. Load a bale on to the machine. To be able to adjust correct overlap, you have to leave the tractor cab while wrapping. Check that the wrapping arm has a speed of approx. 22 revolutions per minute. If not, adjust this by turning the control valve for wrapping arm speed.
Page 24: Operation Instruction
10.0 OPERATION INSTRUCTION. We shall now go through a complete wrapping process, from loading to storage place, and explain the practical use of Auto Wrap 1200 EH. 10.1 LOADING. Pick a bale to wrap. Increase the opening between the rollers as much as possible. Lower the machine almost to the ground.
Page 25 10.8 If it later is required to change the number of revolutions stored in the memory, push the ZERO- button(3) for some seconds and the previously registered numbers are erased. This is confirmed by two lighting points in the display. 10.9 STORAGE PLACE.
Page 26: Periodic Maintenance
Fig. 12-1 12.0 PERIODIC MAINTENANCE. 12.1 BEARINGS. All ball-bearings are packed with grease, and do not need any more maintenance. 12.2 PRESTRETCHER. If the machine is in daily use, the guiding sleeves at the prestretcher should be oiled once a week or when needed.
Page 27 12.5 OIL LEVEL INSPECTION. The oil level must be checked monthly. If necessary, add oil of the same type. 12.6 OIL FILTER. The oil filter must be changed once a year. 12.7 HYDRAULIC CYLINDERS. Make sure that all hydraulic cylinders are closed when storing the machine. 12.8 QUICK COUPLERS.
Page 28: Electric Circut
Fig. 13-1 13.0 ELECTRIC CIRCUT. 13.1 COUPLEFORM. The electric system consists of a remote control unit with supply line, control cable, (14-lead), with plug in both ends, and distributing lines to the different magnet valves and switches on the machine. (See fig.
Page 29: Description Of Hydraulics
Fig. 14-1 14.0 DESCRIPTION OF HYDRAULICS. AUTO WRAP 1200 EH is driven from the hydraulic system of the tractor. The hydraulics of the machine can easily be changed from "Open Centre" to "Closed Centre" hydraulic system. 14.1 "OPEN CENTRE" HYDRAULIC.
Page 30 105 bar, and the valve's mission is to prevent that it by an accident can come high pressure into the return side of the wrapping arm motor. AUTO WRAP 1200 EH NUMERICAL ORDER OF THE MAGNET VALVES The numbers of the magnet valves are identical with the corresponding numbers on the electric leaders.
Page 31 Fig. 14-4 Fig. 14-5 14.5 In order to get a soft conversion between START and STOP of the wrapping arm, the speed is divided in two steps. (This happens automatically). At ½ speed the magnet valve, (pos. 5, fig. 14-2), opens for oil to the wrapping arm, but it goes through a nozzle that limits the oil amount.
Page 32 Fig. 14-6 14.8 The valve block on fig. 14-6 has three valves: Pressure limit valve, (S5), which protects the left roller motor against too large difference of pressure between oil inlet and outlet. Magnet valve, (44), which is activated when rollers out are operated. Non-return valve which prevents oil from flowing to the wrapping arm motor when rollers width is operated.
Page 33: Check Points Before Trouble Shooting
15.0 CHECK POINTS BEFORE TROUBLE SHOOTING. In this chapter we have some general check points that have to be examined first if something is wrong with the machine. In chapter 17.0 we have a more detailed trouble shooting. There are three basic assumptions that have to be fulfilled if the machine shall function properly: The oil pressure from tractor should be 180 bar.
Page 34: Procedure Of Trouble Shooting
Fig. 16-1 BEWARE OF MOVING PARTS WHEN TESTING THE MACHINE. 16.0 PROCEDURE OF TROUBLE SHOOTING. 16.1 MAGNET VALVES. When you shall check if the magnet valves gets electric power, you do this in the following way: Unscrew the nut that holds the solenoid. The solenoid is easy to move without electric power.
Page 35: Trouble Shooting
17.0 TROUBLE SHOOTING. 17.1 THE MACHINE DOES NOT FUNCTION. 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-couplers does not open for the oil. Change quick couplers.
Page 36 17.5 THE ROLLERS WIDTH DOES NOT WORK. Does the magnet valve enough electric power? With many power consumers at the same time, the voltage can fall so much that all functions, or only the width-function does not work. Check the master valve. (Pos. 7, fig. 14-1). If it gets enough electric power and closes the oil flow, the failure has to be found in the magnet valve for rollers width.
