Error 23 DAR Tach Fault-This occurs when the dictated velocity from the CPU exceeds a speed clamp setting. When this fault occurs, the car speed will be further clamped to the speed set by the fault pot on the DAR card.

Possible problems: + Improper DAR adjustment (SL1-SL4, GL, AU pots)

+ Defective terminal slowdown input signal (SUn/SDn)

+ DAR tach fault sensitivity adjustment (F pot)
