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%

Dead-Band Digit

Allowable difference between target and actual

application rate, where rate correction is not

performed.

Range: 1 to 9

1 = 1%

9 = 9%

CALCULATING "VALVE CAL"

The initial Control Valve calibration number for VALVE CAL is 2123 for C-Sd

(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, you may desire to refine this number.
