Simex SIMPACT SPI-94, User Manual

Page: 32 / 52

User manual for flow meter with pulse input SPI-94
controlled due to total flow counter result. It can be set to one of two values :
“lit.” - Litres
“m 3” - cubical meters
Parameters ” t PrEc ” and ” t unit ” are available only if total flow counter is used to
control active current output (
“vALUE”
= ”
tot
”). When current flow rate is used to
control it, the unit and precision of
”OUt LO”
and
”OUt HI”
parameters are
defined by parameters “F unit” , “Ftunit” and “F PrEc” of menu ”Flouu” .
” Lo r ”, ” Hi r ” - this parameters define the output current range (maximum range 0 to 24 mA).
If calculated output value I
out
exceeds defined range then current output
generates the current equal to upper or lower border of the defined range. The
parameters define the percentage extension of nominal current range 4-20 mA
(with 0,1% resolution).
Parameter “
Lo r
” defines lower border of the range due to formula:
I
min
= 4 mA - 4 mA × “
Lo r
” %.
This parameter can be set from 0 to 99.9%.
Parameter “Hi r” defines lower border of the range due to formula:
I
max
= 20 mA + 20 mA × “ Hi r ” %.
This parameter can be set from 0 to 19.9%.
In example on page 38 of the DISPLAY VALUES CALCULATION paragraph
the procedure of the current outputs determining is presented in details.
“
AL
” - this parameter determines the behaviour of current output if any critical situation
occurs. The parameter can be set to one of the values:
“noCHAn” - current will not change,
“22.1” - current will be set to 22.1 mA,
“3.4”
- current will be set to 3.4 mA,
“0.0” - current will be set to 0 mA.
When the critical situation goes, the current will be set to value calculated due to
formulas given above.
If parameter “OUtmod” is set to “on” , “oFF” , “0-20” or “4-20” , the “critical situation”
means that
permissible measurement range
is exceeded.
If parameter “OUtmod” is set to “modbuS” , the “critical situation” means
communication delay (when no data is received) longer than “mbtimE” parameter (see
description:
“rS-485” menu
).
7.3.9. ”briGHt” parameter
This parameter allows user to set bright of the LED display, bright can be set to
conventional values from 1 to 8.
