High Current Electric Pre-Wet Systems
The pre-wet channel on
SpreadSmart Rx
TM
is rated for a maximum
current capacity of 6 amps. If you
are using an electric pre-wet pump that is rated for higher source current levels, contact Cirus Controls for
the Electric Pre-Wet Driver current management module.
Single or Two-Tier Anti-Ice System
The
SpreadSmart Rx
TM
anti-ice system offers automatic integration of two tier dispensing of
anti-ice liquids. By choosing the boom and its nozzles with specific flow rates in mind, the
system offers a wide range of material delivery capability. The anti-ice system automatically
recognizes when the controller asks for output rates that require the output of the
Low Flow Tier 1 boom alone, the High Flow Tier 2 boom alone or the combination of Tiers 1 &
2 (note: Tier 1 is set up with the lowest output nozzles and tier 2 with the highest output nozzles).
Nozzles are chosen so as not to overlap output rates between booms. AI Power Module allows the
SS Rx to switch power to the high current lines for the boom valves.
Details for Single Tier Anti-Ice System
SpreadSmart Rx
TM
will also operate an anti-ice system with a single row of dispensing booms
(one, two or three for left, right and center dispensing). To configure the
SpreadSmart Rx
TM
for
a system with a single tier, answer “yes” to single tier relay as described below and verify that the
boom valves are wired to the tier 1 output signals.
Boom Rating Maximum
Flow Rate Range
Max Gallons/Lane Mile @ 60mph
Tier 1- Low Volume
0 - 8 GPM
8 GPLM ( = 8 GPM)
Tier 2- High Volume
8 - 48 GPM
48 GPLM ( = 48GPM)
Tier 1 + Tier 2 (total)
48-56 GPM
56 GPLM ( = 56GPM)
Note: the gallons per lane mile output at which the system switches between tiers is dependent
upon the boom rating of each tier.
