Flow rate may be too low to register a reading, or
foreign material may be lodged in the flowmeter.
When assembling flowmeter into housing, align
flowmeter pin to hole in the housing.
TOTAL LIQUID USED IS INACCURATE:
This may result from an incorrect FLOW CAL
value. The default FLOW CAL number is 919.0.
This number should be fine tuned as described
in the 'Fine Tuning Flowmeter Set-up section, see
page 66. Other causes may be a flow rate too
low to register, or foreign material lodged in the
flowmeter.
6553.5 MESSAGE DISPLAYED IN THE RATE
MODE:
If this message appears when you are in motion
with the sprayer ON, it indicates that speed sensor
impulses have been lost.
CONSOLE IS ERRATIC IN OPERATION:
If you have a two-way radio, it may be mounted
too close to the console. Keep all Spray Pro
cables away from the radio, its antenna and
power cable.
DISPLAYED MEASUREMENTS DO NOT MAKE
SENSE:
The console may be in the incorrect
measurement mode (US, metric or Turf).
DISPLAY READS OFL:
DISTANCE, TOTAL AREA, SUB AREA, TOTAL
VOLUME and SUB VOLUME will read "OFL"
when they have exceeded their maximum count.
Reset to zero to resume counting. All counters
will read "OFL" if total WIDTH calibration is greater
than 65535.

TROUBLESHOOTING
All Spray Pro
consoles are tested prior to
packaging, so unless there has been damage in
shipment you can be confident that everything
will be operational when you receive it.
However, if you do encounter a problem that
appears to be related to equipment failure,
PLEASE DO NOT OPEN THE MONITOR. Your
system is protected by a warranty and TORO will
correct any defect.
CONSOLE APPEARS DEAD:
Using a test light, check for 12 volts at the power
source. Also check for damaged power cable.
(Monitor requires 12 volts for proper operation).
SPEED IS ALWAYS ZERO OR ERRATIC:
Check for properly established SPEED CAL. The
default SPEED CAL number is .91. Check cable
for breaks or incomplete connection.
For more suggestions on solutions to speed
problems, see 'Checking Individual Components'
section on page 77.
AREA COUNT IS INACCURATE:
Sprayer WIDTH or SPEED CAL was measured
incorrectly or programmed incorrectly. Go back
through the original procedures, make changes,
and test for area count again. Verify accuracy
with formula:
Acres = Distance in feet X Width in feet/43560
DISTANCE COUNT IS INACCURATE:
SPEED CAL was incorrectly measured or
entered. The default calibration is .91, review
calibration, readjust and test.
NO READOUT OF APP. RATE OR TOTAL
VOLUME:
Check to see that the sprayer pump and
equipment are operating properly. If liquid is
moving through the flowmeter, check that the
flowmeter diagnostic light is flashing. For details,
see 'Maintenance, Flowmeter' section, page 73.
Check to see that the FLOW CAL number is
correct. Also check cable for breaks or
incomplete connection.
Check to see that active Boom sections are
registering on the Monitor. When the Master ON/
OFF Switch is ON and one or more section valves
are turned ON, small numerals "1," "2," and/or "3"
should appear in the display area. If not, check
wiring for breaks or incomplete connection.
If the flowmeter has not been used for a long
period of time, the rotor may be sticky. Flushing
the system out with water should make the rotor
spin freely.
TEST SPEED:
Test speed is a built-in ground speed simulator
that is used in performing troubleshooting
checks. When a typical operating speed is
entered, Spray Pro
will respond as if you were
actually driving that speed. It allows you to
simulate your spraying application with plain
water, while remaining stationary, to make certain
that all of the equipment is operating properly.
To enter a test speed, apply the Parking Brake,
place the monitor in TEST SPEED position, enter
calibration, and use the
+
and
-
buttons to
enter the desired speed. The Master ON/OFF
Foot Switch can be turned ON to begin spraying.
APPLICATION RATE can be selected as normally.
Test speed is automatically overridden when real
motion is detected by the speed sensor. Test
speed will not accumulate Distance or Area
measurements.
