For FAST VALVE (C-F or C-FC):
For STANDARD VALVE (C-Sd):
Valve Backlash Digit Controls the time of the first correction pulse after a change in
correction direction is detected.
(INC to DEC -or- DEC to INC).
Range: 1 to 9 1-Short Pulse
9-Long Pulse
Valve Speed Digit Controls response time of Control Valve motor.
CAUTION: Running the Control Valve too fast will cause the
system to oscillate.
C-Sd Valve Control Range: 1 to 9 1-Slow
9-Fast
C-F or C-FC Valve Control Range: 0 to 9 0-Fast
9-Slow
Brake Point Digit Sets the percent away from target rate at which the Control Valve
motor begins turning at a slower rate, so as not to overshoot the
desired rate.
Range: 0 to 9 0 = 5%
1 = 10%
9 = 90%
6) Recheck the new SPEED CAL derived in Step 5 by repeating Steps 2 thru 5.
3. CALCULATING CARRIER "METER CAL"
When calculating METER CAL for a carrier (typically METER 1 CAL is used as a carrier), refer
to the Flow Meter calibration number which is stamped on the label attached to the Flow Meter.
This number is to be used for gallon per area applications. To convert original METER CAL from
gallons to desired units of measure (oz, lbs, or liters per area) see "METER CAL CONVER-
SIONS". Write down this calibration number for future reference when programming the
Console.
NOTE:Reference "PRODUCT INJECTION INSTALLATION AND SET-UP" For information
regarding setting the METER CAL for injection or auxiliary.
4. CALCULATING "VALVE 1 AND VALVE 2 CAL"
The initial Control Valve calibration number for VALVE 1 CAL and VALVE 2 CAL is 2123 for C-Sd
(injection module/standard valve), or 743 for C-F (fast valve) and C-FC (fast close valve). The
VALVE CAL number is used to control response time of the Motor Control to the change in vehicle
speed. After operating the system, this number may be refined.
