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%
4. 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.
See definitions below:
For FAST VALVE (C-F or C-FC):
For STANDARD VALVE (C-Sd):
