4. Maintenance Alert
The Maintenance Alert provides a countdown timer
displayed in tenths of seconds which is used to monitor
the condition of the “Disposable Sleeve” and works only
when running in
VARIABLE
or
CONTINUOUS
mode with
“ RPM OK ” input active. The timer does not countdown
when in OFF . When the time expires, the sprayer is shut
down (spray head and chemical pump are stopped).
A warning is given 1 minute prior to shutdown and after
this point the Snooze feature may be activated.
The Maintenance Alert toggle has two positions:
TIME
REMAINING and SNOOZE .
TIME REMAINING
allows the operator to check or reset
the remaining time. (Time remaining values are stored
on power down.) Holding the
TIME REMAINING toggle
will show the time remaining on the Application Rate
display window. (If Snooze has been activated, a “-“
sign is displayed before the time remaining to indicate
that the spray head is running on borrowed time.)
With the SPRAY toggle switch in OFF * , holding the
TIME REMAINING toggle and then also pressing the
RESET key for 1 second will reset the Maintenance Alert
timer to its preset value. (See Special Calibration: Main-
tenance
ALERT time).
TIME REMAINING displays “ OFF ” if the feature is
disabled. (Special Calibration: Maint. ALERT
Time = “OFF”).
Alarm Indicators: notify the operator on the Sleeve
condition.
No-Alarm (normal operation) Maintenance Alert
Timer > 1 minute:
• None
Alarm-Notify (1 min. warning) Maintenance Alert
Timer < 1 minute:
• Audible Alarm beeps 3 times, then stops.
• Red LED flashes.
• “ ALERT ” message shown on Application Rate
display window, alternates with normal display
values/messages.
Alarm-Active (Sprayer Shut Down) Maintenance Alert
Timer = 0 (Expired):
• Audible Alarm sounds for 3 seconds, then
turns off.
• Red LED flashes.
• Alternation messages “CHECK” and SLEEV”
are shown on Application Rate display window
until Maintenance Alert Timer is reset.
SNOOZE toggle position is used to display the current
“Snooze Count” value or to activate the Snooze feature
which temporarily allows continued operation. “Snooze
Count” values are stored on power down so the Smart-
Flow II will remember how many Snoozes have already
been used.
Selecting the SNOOZE toggle shows the current
Snooze-Count on the Application Rate display
window as long as the toggle switch is held. If the
current Snooze value has reached the MaxSnooze Count
(see Special Calibration Max Snoo2 Count), then Snooze
can no longer be activated and the Snooze Count does
not increment. Resetting the Maintenance Alert Timer
clears the Snooze Count to 0.
NOTE: As a safety mechanism, the Spray
switch is required to be in the OFF position
(not VAR or CONT), because resetting the
Maintenance Alert timer automatically
re-starts the sprayer.
