User Manual For - CONTROLLER/DATA RECORDER MultiCon CMC-99/141
–
Filter time
– defines minimal time that has to elapse from last input state change, if
this change wants to be noticed; Each input has the possibility to sets its own Filter
time, even if this input is part of another, different set of this parameter do not
disturbs their work,
7.9.5.3.
Isolated current inputs module
IS
modules are equipped in six isolated current inputs with different ground potentials,
see
Appendices 8.4. IS6 – Isolated current inputs module
Current inputs parameters are:
–
Name
– each built-in input already has a name given by the device and user cannot
change it, for description of
Name
–
Unit
– parameter which displays measurement unit -
mA
,
–
Mode
– defines measurement range,
–
Low limit
– defines measurement level bellow which in logical channel will be
displayed
Lo
state,
–
High limit
– defines measurement level above which in logical channel will be
displayed
Hi
state,
7.9.5.4.
Analogue flowmeter modules
FI
modules are equipped in two or four analogue flowmeters and same number of
current inputs, see
Appendices 8.5. FI2. FI4, FT2, FT4 – FLOWMETER MODULES
Analogue flowmeters are used to liquids, gases and bulk materials flow measurement, based
on measured sensor current and calculating total flow in selected channel. Each flow channel
is equipped in
IN[n]
input and common ground
GND
. All analogue channels are galvanically
separated from the device.
The user can, thanks to
Scaling
parameter in Logical channel, see chapter
, interpret measured current by the device at its discretion,
which allows to cooperate with any kind of analogue sensors.
Current inputs are used to current measurement in typical ranges (0÷20 mA; 4÷20mA) and to
facilitate their connection, they are grouped and they have common ground, but it is isolated
from the supply voltage and other modules.
Analogue flowmeter parameters are:
–
Name
– each built-in input already has a name given by the device and user cannot
change it, for description of
Name
–
Unit
– parameter which displays measurement unit -
mA
,
–
Base unit
– defines unit which is used by the totalizer (for example when flow
measurement unit is m
3
/s, the base unit is m
3
),
–
Mode
– defines current range of selected input (0÷20mA, 4÷20mA) and the time
base which is used during the measurement (pulses per second, pulser per minute,
pulser per hour),
–
Low limit
– value which determines measured current, bellow which in logical
channel will be displayed
Lo
state, but the actual flow value still will be used in total
flow calculation,
–
High limit
– value which determines measured current, above which in logical
channel will be displayed
Hi
state, but the actual flow value still will be used in total
flow calculation,
