Valve Cal
To ensure that the proper amount of product is being applied, the valve cal must be programmed for the type of
control valve(s) connected to the control system. The field computer uses the valve calibration number to
adjust the response time of the control valve motor to changes in the vehicle speed.
The following control valve calibration numbers are recommended for the valves listed:
Each digit in the calibration number corresponds to a specific function of the valve. The following functions
apply to the digits in the valve calibration number:
Valve Backlash Digit
This value controls the time of the first correction pulse after detecting a change in correction direction. The
values range from 1 to 9, where 1 is for a short pulse and 9 is for a long pulse.
Note:
The backlash digit is not used with a fast, fast close, PWM, PWM close or standard motor control
valve.
Valve Speed Digit
This value controls the response time of the control valve motor. If the valve speed setting is too fast, the valve
will over correct and the system can start to oscillate. The following valves have specific values:
•
Standard Control Valve: This valve has a range of values from 1 to 9, with 1 being slow and 9 being fast.
•
Fast and Fast Close Control Valve: These valves have a range of values from 0 to 9, with 0 for fast and 9 for
slow.
Note:
The speed digit is not used with a PWM or PWM close valve.
Brake Point Digit
The Brake Point digit sets the percent away from the target rate at which the control valve starts to turn at a
slower rate so that it does not overshoot the target rate. The values range from 0 to 9, where 0 is a 5% rate, 1
is a 10% rate and 9 is a 90% rate.
Dead Band Digit
The Dead Band digit is the allowable difference between the target rate and the actual application rate. The
values range from 1 to 9, where 1 equals 1% difference and 9 equals 9% of the difference.
