COMMUNICATION ISSUES WITH CANNODE OR PROSTOP-E
VALVES.
Pentair-Hypro SprayIt app can be used as a diagnostic tool for
verifiying communication with the cannode(s) and actuation
of ProStop-E valves. The SprayIt app can also be used for
checking indivdual spray nozzle patternation or for flow
testing.
LOCAL SPEED IS ALWAYS ZERO OR ERRATIC
• Check for properly calibrated Speed Cal.
• Review GPS speed sensor installation. Check cabling for
breaks or incomplete connections.
AREA COUNT IS INACCURATE
Implement width or Speed Cal was measured or programmed
incorrectly. Go back through the original procedures, make
changes, and test for acre (hectare) count again. Make sure no
width is entered for unused boom sections. Verify accuracy
with formula:
Acres = Distance x Width in feet/43560 Hectares = Distance x
Width in meters/10,000.
NO READOUT OF GALLONS (LITERS), OR GALLONS (LITERS)
PER MINUTE
Check that the sprayer pump and equipment are operating
properly. If liquid is moving through the line, check the flow
sensor to be sure it is screwed all the way into the flowmeter.
Verify that the Flowmeter type and pulses per gallon value
has been entered correctly. Also check cable for breaks or
incomplete connection. If the flowmeter is new or has not
been used for a long period of time, the turbine may be sticky.
Flushing the system out with water should make the turbine
spin freely. Flow rate may be too low to register a reading, or
foreign material may be lodged in the flowmeter.
TOTAL LIQUID USED IS INACCURATE
This may result from an incorrectly entered flowmeter Unit
type and value. Check the number stamped on the flowmeter
tag, and be sure this is entered correctly. If the meter has
been used for some time, wear may have changed the
calibration value. See Fine Tune Meter on page 26.
Check the mounting position of the flowmeter. With lower flow
rates, the meter should be mounted vertically. Also check to
that the flow sensor is screwed all the way into the flowmeter.
Other causes may be inaccurate sprayer tank markings, a
flow rate too low to register, or foreign material lodged in the
flowmeter.
CONSOLE IS ERRATIC IN OPERATION
Check the CONTROL SPEED calibration number in Channel
Setup/Control. If the RATE tends to overshoot or oscillate, the
CONTROL SPEED setting may be too high for the control valve
being used; reduce the CONTROL SPEED setting by 1 (range is
-12 to +3).
DISPLAYED MEASUREMENTS DO NOT MAKE SENSE
The console may be in the incorrect measurement mode
(English or metric).
SYSTEM OPERATION (CONTROL) IS SLUGGISH IN AUTOMATIC
MODE
Check the CONTROL SPEED setting in Channel Setup/
Control. If using a slow valve (4 seconds or more, close to
open) increase the CONTROL SPEED setting.
ELECTRICAL INTERFERENCE
Erratic operation of the system may be the result of electrical
interference from ignition wires or inductive loads (electrical
clutch, fan, solenoid, etc.). Always try to route wires as far
away from suspect areas as possible. If problems occur, you
may need to relocate the console and/or wiring harness, or
install a noise suppressor. Do not use unapproved homemade
wiring harness, which are not shielded or made to factory
specifications.
POWER
Check power source with an electrical meter or test light.
If there is no power, trace cable toward battery looking for
breaks. Also check any fuses or circuit breakers that supply
power to the console.
