SpreadSmart System Troubleshooting Guide
Complaint
Cause (s)
Correction (s)
Set Up Issues
Power Isn’t On
a) Master Power Off;
b) Fuse is blown;
c) Bad Power or Ground connection;
a) Turn on truck;
b) Replace Fuse (s)
c) Verify power/ground connections.
SpreadSmart Rx cuts out or acts
strange;
Low power supply voltage from truck
battery/alternator;
Minimum truck voltage must be >
12.0 volts;
No speedometer signal appears
during test mode.
a) Speedometer cable failure;
b) Signal offset needs adjustment
(VRM speedometer only);
a) Repair/replace speedometer cable;
b) Adjust trim pot for VRM signal;
Auger or Spinner Doesn’t Move
a) PTO not engaged;
b) Hydraulics not functioning;
c) Electrical connection failure;
d) Spreader power off;
a) Engage PTO;
b) Verify Hydraulics: actuate plow or
hoist; manually operate using manual
over-ride on valve;
c) Check LED at coil connection and
at Valve junction box; Repair cable;
d) Check wiring connections;
Auger/Spinner move, but output rates
not indicated
a) Auger sensor failure;
b) Sensor flashes, but signal not
displayed in Test mode;
a) Check sensor wiring and sensor;
b) Check sensor signal cable; verify
that spreader setup shows “sensor
present”;
Operating Modes
Cause (s)
Correction (s)
Automatic mode is unavailable
(Automatic)
a) Installed systems are not set up and
trimmed properly;
b) System(s) not installed in truck,
but enabled in controller setup & not
trimmed (anti-ice not installed)
a) Follow Set Up and Trim
procedure;
b) Follow set up procedure and turn
off any systems not installed in truck;
Pre-Wet or Anti-Ice will not display
when panel button is turned on;
Pre-Wet or Anti-Ice not “enabled”
during system set up;
Follow Set Up and Trim procedure to
enable functions;
Settings on display are shown in %
(not in lbs/mile);
a) Automatic mode: System is not
set up and trimmed properly;
b) Manual mode is selected;
a) Follow Set Up and Trim
procedure:
b) Select Automatic mode;
Flow Rate won’t calibrate
a)Flow meter inaccurate (meter,
sensor or cable);
b) Units conversion error
a) Use test mode to compare pulses to
volume of liquid flowing. Replace
meter or sensor if needed;
b) SS Rx must be set in the desired
units (English or metric) before any
setup occurs. Re-start complete setup
procedure with units set correctly;
Spinner Runs Continuously
Spinner set not to stop with truck;
Follow Spinner set up procedure;
Unable to maintain steady application
at set rate (low speed);
a) Auger is not trimmed properly for
low speed operation;
b) Advanced settings need
adjustment (sticky valves);
a) Re-trim hydraulic system to
improve low speed performance;
b) Adjust parameters – qualified
technician only;
SS Rx display goes blank and
functions stop (on a system that was
working normally before the event);
Probable shorted or open circuit
externally – most often with a sensor,
but may be a damaged cable
connection.
a) Disconnect Hyd Out, Sensor In &
Anti-ice Booms. If SS Rx display
comes back, one of them has a
open/short;
b) Re-connect cables one at a time to
determine damaged component;
c) Replace damaged component;
Multiple Tier Anti-Ice System does
not switch tiers at desired speed;
Anti-Ice Tiers not configured to
switch at desired speed (or output
amount);
Follow anti-ice set up procedure to
set the parameters for tier 1 and tier 2
operations.
