EXAMPLES OF PRESCALER PARAMETERS CALCULATION
Problem:
to measure length of the line with assumed precision.
Essential data
:
- number of pulses per revolution given by sensor
- circumference of measurement circle
- assumed measurement unit and resolution (mm, cm, dm, m).
Example 1
Data:
- circumference of measurement circle:
25
cm
- number of pulses:
100
pulses/revolution
- unit
cm,
resolution
1 cm
25 cm = 1 revolution = 100 pulses
Settings :
mul = “25”
div = “100”
oFFset = “0”
point = “0.”
Example 2
Data:
- circumference of measurement circle:
50
cm
- number of pulses:
100
pulses/revolution
- unit
dm
, resolution
0,1 dm
50 cm = 5 dm = 1 revolution = 100 pulses
Settings:
mul = “50”
div = “100”
oFFset = “0”
point = “0.0”
Example 3
– counter
SLIK-73
used in batcher function (see: Figure 6.2, 6.3)
Data:
–
flow meter:
100
pulses/ L
–
main valve flow (valve 1): about
10
L / sec.
–
measurement precision: up to
0,1
L.
–
valve is open while relay are closed
Settings:
mul = “1”
div = “10”
Point = “0.0”
relay R1 threshold = ”3.0”
- we assume that, since beginning of start of main valve
closing, it will flow about 3 L of water
“A rEL1”
=
“on”
-
access to threshold edition without password
“A oFFS”
=
“on”
-
access to offset edition without password
“Funct”
=
“A - B”
-
input
”B”
is used
programmable input
”C”
- non active if
”Pr inP”
=
”dirEct”
, or any if
”Pr inP”
is set to
other value setting
To change desired quantity of water parameter
“oFFsEt”
should be changed, so it is
displayed first in „quick view” mode.
Pouring starts after pressing of external button [
START pouring
] (Figure 6.3).
