Operational Modes - Description
Accessing the “Mode” Screens
The primary choice screen is called the “mode” screen. From this screen, the operator can access
all normal operating modes, all testing modes, all help screens, all system setup screens and all
material change screens. The mode screen appears as the second screen (after the logo/copyright
screen) after powering the system up. The mode screen can be accessed from other screens by:
1)
During normal operation, by pressing the “AUX (MENU)” button.
2)
During normal operation, by “powering down” the
SpreadSmart Rx
TM
, followed by
“power up”.
3)
During setup and configuration, by pushing “blast” until you have returned to the
mode screen.
Automatic Mode – Ground speed oriented
Automatic mode is the normal operating mode of
SpreadSmart Rx
TM
. In automatic mode, the
SpreadSmart Rx
TM
tracks ground speed and then adjusts output rates based on that speed so the
amount of pounds per lane mile of material dispensed is consistent regardless of speed. To enter
automatic mode, turn unit on and select Automatic from the menu or allow the system to default
into Automatic mode after ten seconds. To dispense material in this mode, the truck must be
moving.
In automatic mode, the granular amount dispensed is displayed in pounds per lane mile or
pounds per mile. Pressing the auger +/- button once will show the set amount, pressing it again
will change the set amount. After three seconds, the measured rate will be displayed again.
The spinner control is shown in number of lanes wide. If the pre-wet on/off button is set to on,
the pre-wet pump is turned on and dispensed rate is shown in gallons per ton. The bar graph on
the right side of the screen shows the liquid tank level.
Alarms
In automatic mode, the sensors are used to determine how much material is being dispensed.
Without these inputs, the
SpreadSmart Rx
TM
can’t accurately measure the amount being
dispensed. The
SpreadSmart Rx
TM
system uses the auger sensor to measure granular material
dispensed, the pre-wet (and/or) the anti-ice flow meter to measure liquid dispensed.
Auger Sensor Fail
:
If the system detects an auger sensor failure, it indicates either a
stopped auger or a bad sensor signal. The system will beep and display “auger sensor fail” in a
flashing sequence on the screen. Simply pressing the auger +/- button will silence the alarm, and
the unit will drop into “open loop auger” mode and continue running. This allows the operator to
verify his operation and (if only the sensor has failed), he may continue to distribute granular
material until repairs can be made.
Pre-Wet Flow Meter Fail
:
If the system detects a pre-wet flow meter failure, it
indicates that either the sensor failed or the pump can no longer function safely, because the tank
is empty. To prevent burning the pump up,
SpreadSmart Rx
TM
automatically shuts the pump off
and raises an alarm. To silence the alarm, simply press the pre-wet (–) button or shut off the pre-
wet alarm. If the system has been set up to allow flow sensor alarm overrides (see Dry Run in set
up), you must press and hold pass then press the pre-wet (+) button, at which point the system
functions in open loop pre-wet mode.
Anti-Ice Flow Meter Fail
:
If the system detects an Anti-Ice flow meter failure, it
indicates that either the sensor failed or the pump is no longer functioning safely, because the
tank is empty. To prevent burning the pump up,
SpreadSmart Rx
TM
automatically shuts the
