Page 4: Introduction
PERATORS ITTING MANUAL INTRODUCTION Congratulations with your new LH 1200 sprayer monitor. During development of this monitor we have made a point of producing a durable product that is primarily developed to monitor chemical application. The monitor however, includes a number of other functions, which enable it to be used in connection with almost any other implement. -

Page 6: General Use
& F ENEREL USE PERATORS ITTING MANUAL GENERAL USE The LH 1200 is especially designed for use on a crop sprayer. The following primary functions can be selected directly from the keypad: Work time Forward speed Area counters (trip- and total) -
Page 7: Seed Drill
When Forward speed is selected and the area override sensor is activated an “r” is displayed on the left-hand side of the display. The LH 1200 is equipped with a system test program, which enables the user to test all connected sensors. For more information, see the ”SYSTEM TEST”... -

Page 18: Flowmeter Calibration (Flow Figure)
LH 1200 LH 1200 O & F NCODING THE PERATORS ITTING MANUAL FLOWMETER CALIBRATION (FLOW FIGURE) Function Flow figure: 1. If this is the first time that the monitor is being used with a sprayer, encode a "start" flow figure of 2000. -
Page 19: Volume Monitoring Calibration For Seed And Fertiliser
The calibration value is the volume per pulse from the sensor. Thus if you let the LH 1200 count the number of pulses during the normal drill/distributor calibration and thereafter divide the amount released (during calibration) by the number of pulses, a new calibration figure for the implement can be found. - Page 20 LH 1200 LH 1200 O & F NCODING THE PERATORS ITTING MANUAL Procedure 1. Prepare the implement for calibration. Do not turn the metering shaft after the monitor has been prepared for calibration. 2. Encode a flow figure of 9999: Press the keys in this order and the monitor is ready for counting pulses.

The form supplied with the LH 1200 can be stuck in the cabin so that the noted values can easily be found and re-entered if necessary. -
Page 22: Fitting The Speed Sensor
LH 1200 LH 1200 O & F ITTING PERATORS ITTING MANUAL FITTING THE SPEED SENSOR We recommend fitting the wheel sensor to the tractors right back wheel. See the following diagram. The distance between the magnets and the wheel sensor must not be greater than 5 mm. - Page 23 LH 1200 O & F LH 1200 PERATORS ITTING MANUAL ITTING The wheel sensor can be fitted to the cardinal shaft on 4-wheel drive machines. A ”bipolar” sensor must be used when fitting to the cardinal shaft. This sensor must be ordered separately as it is different than the supplied sensor (see the...

ERROR WARNING To ensure that data will not be lost, the LH 1200 has a built in error indication: If your LH 1200 displays this error warning, the supply voltage to the monitor is too low. Check therefore the power supply to the monitor (both + and -). - Page 27 LH 1200 O & F PERATORS ITTING MANUAL OTES NOTES LH A...
