4.2.2.6. Input Setup / Input A & B

Input Setup for input channels A & B are specific to each input, however the

actual constants available and the mechanics for configuration are the same.

4.2.2.6.1. Normalization

Normalization is a mathematical Variable Range Constant used to convert

the input frequency into a number that is useful to the user. For instance,

the output of a sensor connected to a wheel driving a conveyor belt is in

frequency, however, feet per minute may be more appropriate. For

example:

Assuming a 0.5 ft diameter wheel and a frequency of 10 cycles/sec;

Feet/minute=(cycles/sec) x (60 sec/minute) x (πD/cycle)

=(10 cycles/sec) x (60sec/minute) x (π x 0.5/cycle)

=(10 cycles/sec) x (94.3)

= 942.5 feet per minute

Therefore the calculated rate is

942.5 ft/min and the normalization factor

(in this instance) to convert cycles /sec to feet/minute =

94.3

alization is entered as a positive or negative number. When using a

to the input frequency first,

Norm

TACHTROL display enter the number as an exponent (see section 4.1.1.1).

Simply type the desired number and polarity when using TACHLINK.

Normalization is mathematically applied

then Equation is applied to the result.
