FUNCTIONS

■ MOVING AVERAGE OUTPUT

This unit samples input signals every H seconds and

outputs proportionally to an average of N numbers of

sampled data. When a new input is sampled after

another H seconds, it gives up the oldest sample and

calculates a new average including the latest sample

and outputs proportionally.

INPUT

H : sampling cycle

OUTPUT

(0.1 to 100.0 seconds adjustable)

N : number of samples to be calculated

(1 to 8 adjustable)

•Step Input with Dead-Time

■ DEAD-TIME COMPUTING

This unit does not respond to an input signal for a

presetdead-timeduration. Inaddition, withadjusting

a time constant T, it generates a ﬁrst order lag output

after the dead-time.

T : lead-time constant

(0.0 to 100.0 seconds adjustable)

•Step Input with Rate-of-Change Limit

■ RAMP BUFFER

This unit output does not change faster than a preset

maximum rate, positive CP and negative CN, no mat-

ter how fast its input changes.

INPUT

OUTPUT

CP: maximum rate of positive output change

(0.00 to 200.00%/second adjustable)

CN: maximum rate of negative output change

(0.00 to 200.00%/second adjustable)

•Example (N=5, U=1, L=1)

■ MEAN AVERAGE OUTPUT

This unit samples input signals every H seconds and,

excluding U numbers of largest samples and L num-

bers of smallest samples, outputs proportionally to an

average of the rest [N – (U + L)] of sampled data. When

the numberofsamplestobecalculatedequals0orless,

it outputs an error.
