8. 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.
–
additional valve flow (valve 2): about 1 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 = ”6.0” - 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
relay R2 threshold = ”3.0” - we assume that, since beginning of start of additional
valve closing, it will flow about 0.3 L of water
“A rEL2”
=
“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
