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.
I
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.

AGITATION SWITCH (POS.B2)
This switch is used to switch the tank agitation on and off (if tank agitation is fitted).
FILL FUNCTION SWITCH (POS. B3)
At present this switch has no function.
AUTOMATIC/MANUAL FUNCTION SWITCHES (POS. B4 & B5)
The AUTO/MAN switch is used to change between automatic and manual spray
rate control.
When this switch is in the "MAN" position (up) the spray rate can be controlled
thus:
• The spray rate is increased by holding the RATE INCREASE/DECREASE
switch up.
• The spray rate is decreased by holding the RATE INCREASE/DECREASE
switch down.
When this switch is in the "AUTO" position (down) the spray rate is controlled
automatically by the computer.
MAIN ON/OFF SWITCH (POS. B6)
The main on/off switch is used to switch the main boom on & off.
• When the switch is in the up position the sprayer is on.
• When the switch is in the down position the sprayer is off.
The individual boom sections are typically switched on and off with the switches
D1 to D9 depending on the LH 85 spray controller model.
SWITCHES C1 TO C9
