SPRAYER SYSTEMS
CHECKOUT
STAGE I : BASIC SPRAYER OPERATING SYSTEM
1. Fill tank with clean water.
2. Park the tractor and sprayer in an open area for testing.
3. Open Air Filter System Water Drain (petcock on bottom of air filter set).
4. Open Air Filter System Oil Drain (petcock on bottom of air filter set).
5. Leave petcocks open so no air pressure can build in the system.
6. Close manifold spray control valves.
7. Connect the tree see cables to control box. Be sure that the Right and
Left side cables are on their correct sides.
8. Start the sprayer engine and bring to operating speed.
9. Check water pressure from pump to insure proper supply to nozzles.
10. Turn on all switches on the control box so all the lights are on.
11. Open Left side manifold valve.
12. Observe Left side spray pattern.
13. If all Nozzles are not spraying properly clean and adjust.
14. Close Left side and open Right side manifold valve.
15. If all Nozzles are not spraying properly clean and adjust.
16. When sprayer operates properly in this mode begin STAGE II.
STAGE II : MANUAL ELECTRIC CONTROL SYSTEM
17. BE SURE BATTERY FULLY CHARGED AND ALTERNATOR MAINTAINS 12 VOLTS +.
18. BE SURE THE CONTROL BOX HAS A GOOD 12 VOLT SUPPLY AND GROUND!
19. THE SYSTEM WILL NOT WORK PROPERLY IF IT HAS LESS THAN 12 VOLTS!
20. Close Air Filter System Water Drain (petcock on bottom of air filter set).
21. Close Air Filter System Oil Drain (petcock on bottom of air filter set).
22. Turn OFF LEFT and RIGHT side MASTER switches (refer to "control box
operation" in the back of the manual.)
23. Bring engine to operating speed.
24. Run for Three minutes to build air pressure. (may take less time)
25. Open Left and Right manifold valves.
a) There should be no spray coming out of the manifold. If there is no spray
coming out of the nozzles proceed to step 26. If spray is coming out of the
nozzles check the air pressure. The air pressure should be approximately 100
PSI. The air pressure can be checked at the schreader valve on the top of
the air tank.
b) If air pressure is good remove an air line from a kingston valve to determine
if air is reaching the valve. Air should escape from the air line that you
removed.(if air escapes proceed to step E) If no air escapes be sure all the
control box switches are off. If the control box power is on repeat the above
process.
c) If air still does not escape check to be sure that the filters and air
line between the air tank and solenoid box are not plugged.
d) If the air line and filters are clear the solenoid needs to be repaired.
Repair the electric solenoid with a solenoid repair kit part # 733062. Once
repaired air should reach the kingston valve and stop the spray.
e) If all switches are off and you have good air pressure, and air escapes
from the air line removed from the top of the kingston valve then replace
the washer (buna disc) and the stem O-ring in the kingston valve. The stem
O-ring and buna disc can be replaced by removing the base portion of the valve
with a 7/8 inch wrench. Once the base is unscrewed pull the stem/plunger out
of the stuffing box and replace the O-ring and seat. Put the valve back together
and try again.
f) The valve should now hold the spray. If the material continues to spray
out the nozzle call for assistance. If the spray has stopped continue to step
26.
26. Turn ON Left Side Master Switch and Master Power Switch. All other switches
should be OFF. (Refer to Control Box Operation for descriptions of each Zone.)
27. Turn ON Zone 1 Left side switch. Zone 1 should spray.
28. Turn OFF Zone 1 and turn ON Zone 2. Zone 2 should spray.
29. Repeat this process until all zones are tested.
30. If any Zone is not spraying properly check for plugged nozzles. If the
nozzle is not plugged look to see if the valve stem moves as the switch is
operated. If Stem does not move check to see if the air pressure has been
released by removing the air line from the top of the kingston valve. If air
escapes then check to be sure that the light for that zone comes on when the
switch is turned to manual. If the light does not come on then you may have
a burned out light or bad switch. Repair or replace as necessary. If the light
works then you may have a broken wire between the control box and solenoid
box or a solenoid that needs to be rebuilt. Repair or rebuild as necessary.
31. Turn OFF Left Side Master Switch.
32. Turn ON Right Side Master Switch.
33. Turn ON Right Side Zone 1,2,3,4, and 5 switches as you did for the left
hand side. Each Zone should spray as the switches are turned on.
34. If any Zone is not spraying properly refer to step 30. Repair, replace
or rebuild as necessary.
35. Stop engine and walk around sprayer listening for any air leaks. Repair
as necessary.
36. Air may be supplied directly to the air tank to from a shop air supply
to check for leaks. Use the schreader valve on the top of the air tank to
apply air to the system.
STAGE III : TREE SEE SYSTEM
37. BE SURE THE BATTERY IS FULLY CHARGED AND THE ALTERNATOR IS MAINTAINING
12 VOLTS +.
38. Make certain all wheel bearings are adjusted and lugs are tight.
39. Insure gap between bolts and proximity switch is 1/8" to 3/16".
40. Listen to be certain every tree see is making clicking sound.
41. If not, check the voltage in control box; the voltage should be 12 to
14.5 volts. If the voltage is good in the control box check the voltage between
socket #1 & #3 at the tree see plug. The voltage between socket #1 &
#3 should be the same as in the control box. If the voltage is not at least
12 volts then there is a short in the harness that needs to be repaired. If
the voltage is 12 volts then replace the transducer and try again with the
sensor. If replacing the transducer does not correct the problem then send
the tree-see unit in for repair.
42. Using Tree See Tester for not-moving System Test. (Refer to "Instructions
For Using The tree-see Tester")
43. Testing individual tree-sees with tree-see tester. (Refer to "Instructions
For Using The tree-see Tester")
a) Checks
i) Observe the switch settings on the 6-dip and 8-dip switches.
ii) Be sure both wires are attached to the transducer (gold disc).
iii) Clean the transducer if dirty with brake clean (use as little cleaner
as possible and clean only when sensor is not working properly).
iv) Replace transducer if torn, broken or damaged in any way.
v) Re-test tree-see, if the unit is working put back on the machine.
vi) If the tree-see is not working replace or run that zone on manual and
send the sensor in for repair.
vii) *NOTE* WHEN YOU CHANGE SENSORS ON THE MACHINE BE SURE THE 6 AND 8 DIP
SWITCHES ARE SET THE SAME AS THE TREE-SEE UNIT YOU TOOK OFF OF THE MACHINE.
viii) Re-connect all sensors and harness connections and test by moving the
machine past objects. The green lights on the control box should light up
depending on the height and shape of the objects you pass to indicate that
a zone should be spraying.
ix) If the lights do not come on when the machine is moved past an object
check to be sure that the harnesses are connected "left to left"
and "right to right" on both the control box and solenoid box. If
the harnesses are connected correctly and the system operates properly skip
to 43. x) if not read below.
a) Open the control box and connect a volt meter between the ground wire (bare
copper wire or black wire) and the green jumper wire on the left/right master
switch. Check the Voltage.(12 volt DC range.) The voltage should read either
over 8 volts or less than 1.6 volts. Then move the machine very slowly forward
or spin the tire very slowly. You should see a voltage change of 8 volts or
more. If there is no change then you either have a broken wire between the
proximity switch and the control box or the proximity switch is bad. Repair
or replace as necessary.
b) If it is necessary to replace the proximity switch be sure that the light
on the side or end of the proximity switch lights up as each pickup passes
the face of the sensor. It should flash 16 times per revolution of the hub.
x) Re-check the system to see if the lights are coming on as the sensors are
passing an object. If they do not, call for a technician to come and check
out the machine.
STAGE IV : OPERATE SPRAYER IN GROVE WITH WATER
44. Check to see if all lights turning on properly.
45. Observe spray turning on and off.
a) The spray should turn on a few inches before tree.
b) The spray should turn off a few inches after tree.
c) The spray should turn off between trees more than three (3) feet apart
unless leadspray and overspray are set too long.
d) Check distance ranging for young trees.
46. Set Tree See tube angles to match Zone spray patterns.
47. Make note of anything not working properly.
STAGE V : IF ANYTHING NOT WORKING PROPERLY
48. Call Roper Growers at 407/656-3233. Report your sprayer condition and
what you have done so far to fix the problem.
49. Repair as directed or request service.

THE 6 AND 8 DIP/SLIDE SWITCHES IN A TREE-SEE
There are two bars of switches in a tree-see unit, one with six small rocker
or slide switches and one with eight rocker or slide switches.
The 6-dip bar is used to set up the delay needed for the distance between
the tree-see units and the spray nozzles. The variables in setting of the
6-dip switch are the length of the sprayer and pulse length.
The 8-dip bar is used to control the amount of lead and over spray that is
needed. This is determined by the owner/operator of the sprayer.
*********** THE 6 DIP SWITCH ***********
When a sprayer is first equipped with Tree-See the 6-dip setting is done. But there are a few cases where this might need to be changed. The first is if the length of the sprayer changes, this is not a common occurrence. It is possible that pulse length can change. Changing the tire size on a sprayer with a proximity switch will change the pulse length and the 6-Dip will need to be reset.
--------------How to Find the pulse length---------------
For a proximity switch equipped sprayer it is necessary to know two things.
First is how many bolts or holes pass in front of the proximity switch in
one revolution of the tire.
The proximity switch is activated by these lugs or holes. Newer units have
a disc mounted on the inside of the hub with 16 holes instead of bolts.
The second is the rolling circumference
of the tire i.e. (how far the sprayer travels in one revolution of the tire).
This is measured by putting a mark on the tire and one on the ground. Roll
the wheel one revolution and put a new mark on the ground after one revolution.
Do this at least two times to check the accuracy of the measurement. Standard
sprayer tires normally roll out between 10 and 13 ft.
Take the rolling circumference in inches and divide that by the number of
bolts or hole in the proximity ring and this will give you the pulse length.
Example a tire rolls out at 10 ft. 11 in. and the disc has 16 bolts. {(10
ft. x 12 in. = 120 inches) (120 in. + 11 in. = 131) (131 in./16 bolts = 8.19
in. pulse length)}.
********* To Reset 6 Dip Switch *********
Measure the distance between the center
of the tree-see tube and the nozzles in the back of the sprayer. For a self-powered
sprayer the distance will be around 156 in. for the
left side and 9 in. more for the right. For a p.t.o. sprayer the distance
is approximately 130 in. for the left side.
Now divide the number of inches from the tree-see tube to the nozzles by the
pulse length.
Example: (156 inches from the center of the tree see tube to the nozzles, with a pulse length of 8.19 in.) 156 / 8.19 = 19.04.
Round your answer to the closest number
in this case the number would be 19. Then subtract 6 from that number and
that is the number of pulses that will need to be programmed into the tree-see
sensor. This is to be done on the 6 dip switch in the tree
see sensor. Each of the numbers on the 6 dip switch refer to a certain number
of pulses this chart will show you how many pulses each switch represents.
19 - 6 = 13
The dip switch is unusual in the way it
counts it is a Binary switch.
Switch Number 1 2 3 4 5 6
Number of Counts 1 2 4 8 16 32
Example: COUNT of "13" X X
X
In this case you would turn on switch numbers 1 , 3 and 4 represented by 1
+ 4 + 8 = 13. To turn on a switch the switch must be rocked or pushed towards
the number on the switch.
This process sets up the delay from where the tree see sensors are at the
front of the machine to where the spray nozzles are in the rear. ONCE THIS
IS SET IT DOES NOT NEED TO BE CHANGED UNLESS THE TIRE SIZE CHANGES !
************************ IMPORTANT ************************
ALWAYS RUN CORRECT AIR PRESSURE IN THE TIRES!!!!
Low air pressure changes the rolling circumference of the tire. Do not let
wheel bearings get loose since a wobbling wheel can damage the proximity switch.
Always replace the same length lug studs after you change a tire. A short
lug will not be read by the proximity switch. A longer lug will damage the
proximity switch. DO NOT USE STAINLESS STEEL BOLTS
***********************************************************
The second set of dip switches has 8 switches. These are used to set the lead
spray and over spray. You will notice that each has a number just like the
6 dip switch. On the 8 dip the number 5 switch must be in the on or closed
position (towards the number) or the tree see sensor will not operate properly.
By turning on switches 4-1 in additions to the number 5 switch you can cause the tree see sensor to turn on the spray earlier. By turning on switches 6-8 you can cause the spray to stay on longer past the tree. To do this you must turn on the switch closest to the number 5 first in a descending or ascending order. Each additional switch you turn on will add the length of your pulse that you calculated earlier. Example: With the number 5 switch set the sensor will come on at the starting edge of the tree and turn off at the end of the tree. If you turn on the number 4 switch with the number 5 the tree see will turn on 8.19 inches before the starting edge of the tree and turn off at the end of the tree. If you turn on the number 4, 5, and 6, switches the tree see will turn on 8.19 inches before the tree and stay on 8.19 inches after the tree. You can repeat this process to obtain 33 inches before the tree and 24 inches after the tree.
You must be sure that ALL of the bolts or lug nuts are in the wheel and they pass within 1/4 of an inch of the proximity switch. If any of the bolts are missing the tree see sensors will turn on and off at the wrong places. If the proximity switch is farther than 1/4 of an inch from the bolts or lug nuts the switch will not detect them and the system will not operate properly.
If you have any questions or problems
give us a call and we will solve them over the phone if possible or come and
repair the problem.

INSTRUCTIONS FOR USING THE TREE-SEE TESTER
The tree-see tester can be used in two different ways. The first is as an individual tree-see tester. The second is as a pulse generator which simulates the pulse that would be generated if the sprayer was moving.
TESTING AN INDIVIDUAL TREE-SEE
The first step for this operation is to attach the power leads from the tree-see tester to a ground and a B+ (12V Positive) source. The black clip should be attached to a ground and the red clip to a 12V positive.
At this point you are ready to use the tree-see tester. To test a tree-see simply connect the tree-see unit to the black plug on the end of the tester. The tree-see should start to click and if the unit is pointed at a target the green light on the side of the tester should light up. The range of a tree-see unit is 1 inch to 21 feet. If the green light turns on when you point the sensor at a target you know that the sensor is detecting a target and creating an output ground. Point the sensor away from the target to an open area with no possible targets and the green light should go out on the tester. If the light turns on with a target and off without a target then the sensor is operating properly.
If the sensor is not operating properly check the power supply to the tester first. Second check the wires to the transducer (gold disk on front of the sensor unit) and make sure both are attached securely. If the sensor still does not operate properly change the transducer and re test the unit. If after re testing the unit does not work return it to Roper Growers for repair. If the tree-see works correctly with the tester then the problem is most likely in the wiring harness on the sprayer.
USING THE TESTER AS A PULSE SIGNAL GENERATOR
In normal operation a tree-see equipped sprayer turns off automatically five (5) seconds after the sprayer has come to a stop. To simulate the moving sprayer you can use the tree-see tester as a pulse signal generator.
On machines manufactured after 11-10-91 you can connect the tester directly to the receptacle on the side of the control box just above the latch. Connecting the tester to this receptacle will cover all the connections listed below. If you have the receptacle on the side of the control box skip to "NOW THAT YOUR CONNECTED"
If your machine does not have the receptacle on the side of the box please follow the directions on the next page.
*** SPECIAL NOTE *** BE SURE TO PUT THE PLUG BACK IN PLACE ON THE RECEPTACLE AFTER YOU ARE FINISHED WITH THE TESTER.
NOW THAT YOUR CONNECTED
First open the control box mounted on
the tractor, this is the easiest place to make the necessary connections.
Take the special green lead which is supplied with the tester and insert the
pin into the number 7 position (small number are printed on the face of the
black connector end of the tester). Now connect the alligator clip to the
green jumper wire on the Master Left & Master Right switch. Turn on the
main power switch and the Left and Right Master switches. The green zone lights
will come on if the individual tree-see units have a target. If the lights
do not come on when the sensors have a target refer to the
** SPECIAL NOTE ** below.
** SPECIAL NOTE ** It is possible that
the proximity switch is grounding out the output from the tester. To eliminate
this possibility disconnect either the Left or Right harnesses connection
from the Solenoid box.
