For FAST VALVE (C-F, C-FC, or C-P):
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
C-P 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%
6. CALCULATING "VALVE CAL"
The initial Control Valve calibration number for VALVE CAL is 2123 for C-Sd (standard valve), 743
for C-F (fast valve) and C-FC (fast close valve) or 43 for C-P (PWM 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:
