“ANALOGUE VARIABLES” CHART
Analogue variables
By selecting “Analogue variables” you can display the 4 magnitudes listed below:
a.
“
Temperature 1 (channel 1 of the VMUP) °C
”
b.
“
Temperature 2 (channel 2 of the VMUP) °C
”
Note : these inputs (channel 1 and 2) for temperature measurement can read data from
“Pt100” or “Pt1000” probes with 2 or 3 wires.
c.
“Pulse rate input (VMUP pulse input)”
Note : the pulse frequency input allows to measure a frequency signal for flow or speed
measurements.
d.
“ Analogue input (analogue input “
mV
” or “
mA
” of the VMUP) ”
Note
: the “mV” type analogue input is available on the module VMUP
2TIW
XSEM ….
The “mA” type input is available on the module VMUP
2TCW XSEM.
The box shown below allows to select the master to which the VMUP is connected:
This selection allows to set whether the displayed variables belong to the VMU-P directly
connected to the VMU-C EM or to one of the VMU-M EM connected by RS485 to the
VMU-C EM itself. Variables relevant to disconnected sensors are marked with an
asterisk and not shown by default.
