3)
Hold RPM constant while unit is calibrating. This may take as much as two minutes.
(You may cancel the trim test at any time using the blast key.)
4)
Once the automatic trim calibration test is completed, the user is asked to “accept
calibration”. Select “Y” using the spinner control, and then press pass.
5)
The zero velocity trim is now set, select blast to save and return to the main menu.
Pre-Wet Pump Set up and Trimming
VERIFY THAT FLUID IS PRESENT IN TANKS B/4 BEGINNING OPERATION.
1)
Power the system down and up and enter the configuration menu as before. Then, using the
spinner button, select trim/cal and select pre-wet. The screen will now display the pre-wet
settings. Use anti-ice toggle to change settings.
a.
Prewet Present: default is yes;
b.
Sensor Present: choose NPN, PNP or No; Default is NPN;
c.
Minimum Trim: do not adjust yet;
d.
Maximum Trim: do not adjust yet;
e.
Pulses per Gallon: enter the pulses per gallon rating of your flow meter. Refer to
flow meter manufacturer to determine the signal pulses sent by the flow meter for
each gallon (or liter if set in metric mode).
1)
Micro Trak FM500 – flow meter used by Cirus Controls
a)
Gallons:
Pulses per gallon = Flow cal number / 2
b)
Liters: Pulses per gallon = Flow cal number / 7.58
2)
Raven brand flow meters are listed in pulses per 10 gallons.
a)
divide the flow meter rating by 10 and input that value.
Note: units of measure here must match units of measure in master set up. If you are
changing from English to Metric units, you must start at the first setup step and be
consistent or calibration errors will occur;
f.
Pump max. Gal/minute: enter the max output rating of your pre-wet pump.
g.
Prewet Units: choose between gallons/ton (default setting) and gallons/mile
2)
Press the s control until the minimum trim setting is selected.
3)
Press pass to enter trim calibration.
4)
Choose either automatic (requires flow meter) or manual (with or without flow meter)
calibration. The unit can automatically calibrate the trim settings using the sensor as
feedback. If you wish to manually trim the pre-wet pump (faster for more experienced users),
select manual trim.
Automatic Pre-Wet Pump Trimming and Calibration
If you selected auto trimming, the unit automatically selects the trim levels using the flow sensor.
1)
Step through the instructions using the pass button to begin trim calibration.
2)
Once initiating auto trimming, you have 10 seconds to raise the engine RPM.
