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.
Standard Valve Control
Range:1 to 9
1-Slow
9-Fast
Fast, Fast Close Valve Control
Range:0 to 9
0-Fast
9-Slow
PWM, PWM Close Valve Control
Range:0 to 9
0-Slow
9-Fast
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%
4.
CALCULATING "VALVE CAL"
The initial recommended Control Valve calibration number for VALVE CAL is 2123 for Standard
Valve, 743 for Fast Close Valve, 743 for Fast Valve, 43 for PWM Valve or 43 forPWM Close Valve.
The VALVE CAL number is used to control response time of the control valve motor to the change
in vehicle speed. After operating the system, this number may be refined. See definitions below:
For FAST VALVE
For PWM VALVE
For STANDARD VALVE: or FAST CLOSE VALVE: or PWM CLOSE VALVE:
