Testing the Boom Tiers using No Speedometer Mode
No Speedometer mode can be used to test the flow rates of each boom and of each tier in a
stationary truck.
SpreadSmart Rx
TM
automatically determines which boom tier runs based upon
the rating of the booms (in GPM), the calibration settings in the system, on the speed the truck
runs and on the flow rate (in GPL-M) selected by the operator. No Speedo Mode can be used to
simulate truck speed in a non-moving truck to allow you to verify that each boom tier turns on
and off at the planned flow rate.
To make the determination, verify the flow ratings of your boom tiers and using the chart
above to select several combinations of flow rates and speeds which are just above or just below
the rates where the flow ratings of the tiers overlap. For example in a truck with tiers rated at a
maximum of 8GPM for the low flow tier and 48 GPM for the high flow, we suggest you select
speed and flow rate combinations that allow you to test for flows at 7, 9, 47 & 49 GPM (one
gallon above and below the max rating of each tier).
To use “No Speedo” mode to simulate the speed / flow rate combinations for above:
1)
Menu button on, automatic on, all boom buttons off. Pass to select “No Speedo”;
2)
Display should show the current flow rate in GPL-M, should show that none of the
boom buttons are highlighted (in off position), should show the default liquid
material selected, and at the bottom of the screen should show 0 mph.
3)
Select “pass”, screen will respond with the word <pass> in brackets. Use the anti-
ice toggle to increase the mph to the desired speed. Hit “pass” again to begin the
simulated movement. <pass> will disappear from the screen.
4)
Use the anti-ice toggle to increase or decrease the rate of liquid delivery (in GPL-M).
Verify that there is liquid in the anti-ice tank and that dispensed liquid will not cause
problems.
5)
Open one or more boom valves by turning on the corresponding boom button.
6)
Continue the test at each of the planned combinations of speed and flow rate settings
to determine if correct boom tier operates as planned.
7)
Turn off boom buttons to complete the test and return system to auto mode by turning
menu button off and automatic button on.
Test Mode – No ground speed interaction
The technician, when verifying hydraulic valve outputs and sensor inputs, normally uses this
mode. All output rates are displayed in percent of full scale and sensor inputs are displayed in
pulses per minute. With the pre-wet button on, the pre-wet output level and pre-wet sensor are
displayed; with the pre-wet sensor off, the speedometer sensor signal is displayed.
Test mode may be used as an operating mode when a “no ground speed interaction” mode is
desired (aka: completely manual operation). Material output is not related to truck motion or
speed and is controlled only by the settings for the auger/conveyor, spinner, pre-wet, and anti-ice.
Unload Mode – Granular or Anti-Ice
This mode is used for unloading the truck and computer simulates motion to allow the over-ride
of the safety feature that prevents material from pumping unless the truck is moving and boom
switches are on. Note: verify proper valve settings for system before operating unload mode.
All three media (if they are enabled) are displayed on the Unload Mode Screen, however, no
dispensing can occur unless the on/off button is “on” and the % output is raised above “0%”.
Material can be unloaded individually or simultaneously if you choose. Note: Pre-Wet Material
is normally not unloaded using the SpreadSmart Rx controller. Most systems are plumbed with a
manual unload valve/spigot.
