LH 3000 OPERATING MANUAL INTRODUCTION Congratulation on your new LH 3000 monitor. This monitor is an advanced auxililary machine, which can be a great assistent for you for many years, presupposed correctly, encoded, used as maintained. In the development of the LH 3000 great importance was attached to the simplifying of the daily use. This has been made by “removing” all encoding keys and arranging all encoding values in a register under only one key, the “SYSTEM” key.
LH 3000 OPERATING MANUAL DESCRIPTION OF THE SYSTEM On the below drawing the LH 3000 system is illustrated. The standard kit has been made with full-drawn lines and extra equipment with broken lines.

Step application (reduction) Manometer pressure in bar Step application (increase) Print of stored data in the memory Field No.
LH 3000 OPERATING MANUAL OPERATION IN GENERAL All encoding values (basic data) for the calculations are divided in 14 values (1 – 14). Th encoding values will appear by pressing the “SYSTEM”-key after which the numerical keyboard will be lit and the values can be encoded. By repeated press on the “SYSTEM”-key the order of encoding values (1 – 14) can be leafed through. A “bip” will sound when a key is pressed during normal operation (not during encode) and the chosen function will be lit.
LH 3000 OPERATING MANUAL 01 WORKING WIDTH The working width is the width measures in cm represented by the implement. Thus 1500 has to be encoded for a 15 m sprayer. NB! If boom compensation has been fitted the individual section must be encoded under “04 section”. Exit the encoding as described above when completed and the new value will be stored automatically in the memory. Encode as follows: Press for about 3 seconds.
LH 3000 OPERATING MANUAL The effective wheel circumference is much dependent on tyre pressure, weigth, ground conditions, etc. Therefore it is recommended to check the wheel circumference frequently an write it on the supplied form for the various implements. Method 2: Use this method when the speed sensor has been fitted at cardan or similar. Here the monitor is used in normal operation (not incode mode). 1. Measure a distance of 100 m. 2. Drive the tractor to the “start” mark. 3.
LH 3000 OPERATING MANUAL 04 BOOM SECTION Is electronic for boom compensation fitted the LH 3000 can take account for shutting of one or several sections when calibrating area and chemical consumption. To enable the monitor these calculations the following must be encoded: A. Number of sections of the boom. B. The width of the individual sections. Use the following procedure: Choose ENCODE 04. The display changes between 04 to the left and another figure to the right. A: 1.
LH 3000 OPERATING MANUAL 05 CHOOSE OF SPEED SENSOR LH 3000 can operate with 3 individual speed sensors: 1. Sensor mounted on tractor wheel. 2. Sensor mounted on trailed implement (can only be connected via electronics for boom compensation). 3. Radar. Select sensor by encoding the corresponding number. NB! Check that wheel circumference corresponds to the selected wheel sensor. 06 ALARM LIMITS FOR APPLICATION RATES Here the maximum accepted deviation can be encoded. Encode the figure in per cent.
LH 3000 OPERATING MANUAL 08 ALARM LIMITS FOR RPM Here the maximum accepted deviation for RPM is encoded. Encoded in per cent. NB! This function is only active if a RPM sensor has been mounted and the wanted RPM has been encoded. (See the –key). The alarm will be given by 3 “bip” (repeated at fixed intervals) and at the same time the following will be displayed: ERR 6 = revolution figure too high ERR 7 = revolution figure too small IMPORTANT: Is no alarm wanted 0 must be encoded.
LH 3000 OPERATING MANUAL 12 METRIC/IMPERIAL LH 3000 can operate with 2 individual measuring units. Metric: Imperial: Speed in kilometres per hour (kmh). Speed in miles per hour (mph). (HA): The area is displayed in hectare (ha) (AC): The area is displayed in acres (ac) Flow volume in litres (l). Flow volume in litres (l). Is the metric system selected “HA” is displayed. Is the Imperial system selected “AC” will be displayed. Switch between the two systems by pressing the “MEMO”key.
LH 3000 OPERATING MANUAL FUNCTION KEYS RPM By pressing this key RPM will be displayed (sensor must be mounted). WARNING: Is control of RPM wanted the wanted RPM figure must be encoded here as follows: 1. Press 2. Encode the wanted RPM. 3. Press NB! for app. 3 seconds, until figure keys are lit. again. The maximum deviation to be encoded during encoding (“SYSTEM”-key) point 08. The warning function is only active when the implement operates. TIMER The timer shows consumed working time.
LH 3000 OPERATING MANUAL METRES Travelled distance in metres since last zero setting. Maximum display 99999 metres after which the counter restarts from zero. The meter counters is zeroed by pressing the key simultaneously by the key. REMAINING AREA Remaining area to work. The function presupposes encoding of area before start. To be done as follows: EXAMPLE: The field is 10.40 ha. 1. Press 2. Encode 1040 on the keyboard. 3. Press for 3 seconds until the figure keys are lit. .
LH 3000 OPERATING MANUAL TRIP COUNTER: Press . Then press until “STO” is displayed followed by 3 quick warning tones. The counter is zeroed. TOTAL COUNTER: Press and then keep the simultaneously for app. 3 seconds. The counter is zeroed. keys pressed Note: Zeroing of deleting of trip counter will cause zeroing of TIME and CONSOMPTION FROM TANK at the same time. AREA PER HOUR Area worked per hour (working efficiency). LITRES PER MINUTE Control of flow in the flow meter measures in litres per minute.
LH 3000 OPERATING MANUAL CONSUMPTION FROM TANK Two litre counters record the consumption from the tank. Both can be read from this key. TRIP LITRE CONSUMPTION FROM TANK: Press displayed. and the trip consumption from the tank since last zero setting is TOTAL LITRE CONSUMPTION FROM TANK: Keep the key pressed and the total consumption from the tank since last zero setting will be displayed. The litre consumption (trip and total) can be stored for later print of job cards. See “JOBNO” and “MEMO”.
LH 3000 OPERATING MANUAL APPLICATION By pressing this key the actual application in litres per hectare is displayed. WARNING: To control the application rate the wanted rate is encoded here as follows: 1. Press for app. 3 seconds until the figure keys are lit. 2. Encode the wanted application. 3. Press again. NOTE: The maximum deviation is encoded during the encode (“SYSTEM”-key) point 07. The warning function is only active when the implement works.
LH 3000 OPERATING MANUAL JOBNO The job number is used for numbering the job in question. Therefore the use of “JOBNO” is only of interest when print of job cards is required. EXAMPLE OF OPERATING THE KEY: Registration of the job number 1234567: 1. Press 2. Encode 1 2 3 4 5 6 7. As the display is only 5-figured it will change between 1 2 and 3 4 5 6 7 in the next picture. 3. Press . Numerical keyboard disappears and the above job number has been registered.
LH 3000 OPERATING MANUAL CLEAR The “clear” key is used for deleting any encoding and works almost like the c-key of a pocket calculator. Used for deleting encode of faulty figures. Besides the key is used for zeroing of total counters (flow + area). EXAMPLE: Zeroing of “area”: 1. Press 2. The area counter is now zeroed. NB! and simultaneously until the display is blank. The “CLEAR” key and the “MEMO” key are also used together for deleting the memory.
LH 3000 OPERATING MANUAL TEST OF SENSORS Encode a working width of 6666 as follows: for app. 3 seconds until the display changes between 01 and the Press encoded working width and the numerical keyboard is lit. Encode 6666. Press and the display shows "TEST" (flashes). The individual sensors can now be tested. SPEED SENSOR Press To the left in the display the sensor selected in "ENCODE" will be shown.
LH 3000 OPERATING MANUAL PRESSURE SENSOR Press "t" appears to the left in the display and "ON/OFF" changes to the right when the pressure sensor is activated. MOTOR CONTROL By pressing respectivly. or the regulation valve should go up or down "+" = up "-" = down IMPLEMENT SENSOR The control lamp on the monitor shows if the implement sensor works. NB! Choose the right imple ment sensor in ENCODE point 13.
