Manual Anti-Ice Pump Trimming and Max Flow Setting
If you selected manual trimming, you must manually raise the hydraulic level using the Anti-Ice
button, and either observe the pulse count returning from the flow sensor (if equipped) or visually
observe fluid being dispensed.
1)
Raise the hydraulic level until the Anti-Ice pump is barely pumping.
2)
Press pass to accept minimum trim level.
3)
Increase the hydraulic level until maximum Anti-Ice fluid flow is achieved.
4)
Press pass again to accept the maximum trim levels.
5)
Once the maximum trim level is accepted, the user is asked to “accept calibration”.
Select “Y” using the spinner control, and then press pass.
If the vehicle does not have a Anti-Ice flow meter, open loop trimming is used. In this case, enter
the maximum pump flow for the pump installed (gallons or liters /minute), and the
SpreadSmart
Rx
TM
unit will use this value to calculate the amount of Anti-Ice material dispensed. In an open
loop system, recording of amount of material dispensed by the system is based on a system that is
not “calibrated” and therefore is not a “certifiable” value.
Validation of Flow Meter Ratings using SpreadSmart Rx
Confirm your Calibration:
to validate that you are delivering the planned amount of
fluid from your liquid system regardless of which flow meter is in use:
a)
Plumb your liquid system to allow you to catch and measure an amount of fluid from
a single port (2-3 gallons or 8-12 liters). Add enough fluid to do the calibration;
b)
From the menu screen, select Test mode, enter the password;
c)
Ramp up the output on the liquid system in use until the pulses coming back are equal
to the flow cal number (such as 1500). Liquid will be flowing at this point:
d)
Collect fluid for exactly one minute. The volume of fluid collected is equal to the
volume flowing in one minute. Because the test mode allows you to see pulses
expressed in ppm (pulses per minute), the amount of fluid you collect will tell you if
your pulses per gallon (or liter) rating on the flow meter is correct for the spreader
control.
e)
If the test gives you more or less fluid than you expected (off by more than 3%),
adjust the pulses per gallon (liter) in the spreader setup to compensate for the
variation you experience.
f)
The variation is most likely due to the fact that different flow meters are calibrated
using different methods and different fluids, not because of any problem with the
flow meter or the spreader control.
g)
Flow meters supplied by Cirus Controls will have the correct pulses/gallon
conversion shown on the actual flow meter for use during the set up step.
