PERATORS MANUAL FOR THE LH 85 SPRAY CONTROLLER

INTRODUCTION

The LH 85 Spray Controller is not only a powerful spray rate controller, but also a command centre for the whole sprayer!

Whilst designing this unit we have tried hard to ensure that operation is as simple as possible, the ergonomically designed housing and the menu based operating system ensure that the unit will be a pleasure to use for many years.

A large amount of the system is built up around easily understood icons and instructions on the display in clear text make this operator's manual almost redundant, however we recommend that this manual be used as a reference for the many functions available.

Despite the fact that this manual is large and may, upon first impressions, seem to be too much to read, we ask you to study at least chapter 2 where the basic functions of the system are explained.

NTRODUCTION

Examples are used throughout this manual to ensure that finding a solution to any problems that might arise can be solved simply by changing the values in the examples with the values required for the task in hand.

Our experience tells us that it is a good idea to familiarise yourself with the system before the first day of use thus avoiding delays in getting the job done!

Please keep this operator's manual within easy reach and together with the LH 85.

REGULATION ACTION

The regulation action values are used to adjust the "speed" at which the system

adjusts the regulation valve.

The fast regulation action value brings the actual rate quickly towards the required

rate. As the actual rate gets closer to the required rate the precise regulation

action value takes over and controls the valve in smaller "steps".

The two different values used (fast & precise) are explained in the following:

FAST REGULATION VALUE

The fast regulation action value affects regulation when the actual rate is far from

the required rate.

If the system is too slow to find the correct rate then the values should be

increased.

If the system is too unstable then the values should be decreased.

Minimum regulation pressure:

Encode the pressure, in bar, that the sprayer may not go under.

The working pressure will not go lower than this encoded level even if a lower pressure is required by the regulation system (the controller).

Should the actual pressure on the sprayer be lower than this encoded value the regulating system will continue to increase the pressure until the minimum pressure level has been reached.

Maximum regulation pressure:

Encode the pressure, in bar, that the sprayer may not go over.

The working pressure will not go higher than this encoded level even if a higher pressure is required by the regulation system (the controller).

Should the actual pressure on the sprayer be higher than this encoded value the regulating system will continue to decrease the pressure until the maximum pressure level has been reached.

4.20 LH

AGRO

PERATORS MANUAL FOR THE LH 85 SPRAY CONTROLLER

Regulation valve time:

Encode the time, in seconds, that the regulation valve takes from fully closed to fully open (or fully open to fully closed).

This value should found by measuring the actual time the valve takes from fully closed to fully open (or the opposite) when the system is supplied with 12V.

Minimum voltage:

Encode the lowest voltage at which the regulation valve starts to move.

The controller uses variable voltage to control the valve; the closer the actual rate is to the target rate, the lower the voltage sent to the valve is. The minimum voltage must therefore be found when the valve is under pressure as this affects the force required to move the valve.

Regulation dead band:

Encode an acceptable regulation dead band in percent.

ETTINGS

Regulation will stop when the difference between the target rate and the actual rate is lower than the encoded dead band (percent of the target rate). This is to prevent the valve from oscillating when the actual rate is near the target rate.

Regulation backlash:

Encode the time in seconds it takes before the valve starts moving after a direction change.

Anticipation factor:

Encode the anticipation factor to ensure that the regulation valve is in a suitable position when switching the main valve on when, e.g. turning on the headland.

0 = OFF The reg. valve remains stationary at the position when the main

valve was switched off.

100 = FULL The reg. valve will move completely to the calculated position.

The number of boom sections open, the target rate, the average forward speed, the regulation valve time and the maximum reg. valve capacity are used to calculate a theoretical position of the regulation valve when the main valve is OFF, e.g. when turning on the headland.

The anticipation factor expresses how much of the time needed to reach the theoretical valve position will actually be used to drive the valve.

Example: The calculated position will take 1 second to reach; setting the

anticipation factor to 50% will result in the valve moving for ½ second instead of 1 second.

Default valve position:

Encode the required position of the regulation valve in percent of fully open.

When the main valve has been switched off for 10 minutes the reg. valve will move to this position.
