Technological Innovation Means Saving

Electric Measurements

The new and economical SMART Pił
analyzer futher broadens the
consolidated family of MACH 30 (three- phase
and SMART panel board-type analyzing instruments. It
is the pr0duct of strategy aimed at
consolidating the brand's presence in the
field of measuring instruments through a
line of highly technological products and
systems that meet Company's traditional
needs to economize and optimize electricity
consumption.
The SMART Pił panel board-type
analyzers have been designed and
manufactured to be used in low and medium voltage
electricity distribution panel boards. The SMART Pił
measures and
computes the main electric quantities
specified in the table on page 36. The
computing values of average powers may be
set for times ranging from 1 to 60 minutes .
The precision is about 0,25% 25 quantities
may be viewed in a series of pages on a
liquid crystal display on front. Finally an
extremely important plus is that an RS-485
serial port is available in each SMART Pił so that measurements can be sent to a data
recording system as described in the "ENERGY
MANAGEMENTS " section.

Load Control Pulse
Outputs
|
|
Lo SMART Pił, nella versione 2p , ha due
rele di uscita che possono essere
configurati dall'utente in tre diverse
modalita come di seguito riportato
The 2p version of SMART Pił has two output
relays that can be configured in three
different modes as follows
|
"Load control" mode
The SMART Pił analyzer incorporates a
"LOAD CUTOUT" function for controlling
power peaks in order to avoid costly surcharges.
A
sophisticated predictive algorithm monitors
the power consumption trend. Whenever it is
dermined that the maximum allowed value may
be exceeded, an output relay is activated
and load is cut out.
As result, before the
power peak arises , non-priority loads can
be cut out or the user warned.
"Alarm Threshold" mode
The SMART Pił analyzer incorporates an
"ALARM THRESHOLD" function for
keepeng the maximum values of the main
electric parameters under control.
If a
parameter exceeds a programmed value, a
relay to which the threshold has been
assigned is activated.
This function enables the user to control peak values of
voltage, current etc.
"Pulse Emission mode"
The SMART Pił analyzer incorporates a
"PULSE EMISSION" function for
transferring data on the consumption of
Active Power (kW) and Reactive Power (k VAr)
to a PLC.

Why The Load Cutout Function?
|
|
SMART Pił represents a technological
innovation because besides being a highly
precise measuring instrument it can signal
when loads exceed a set level and disconnect
users that have been identified in advance
by the Company in order to avoid excessive
consumption and reduce the power demands
make of the electric company. Let's not for-
get the power is paid not only on the basis
of a fixed charge but also according to
demand , which means high costs per KW,
The diagram illustrates the concept clearly,
When the instrument detects the the power
limit is about to be exceeded, it signals
the necessity of disconnecting loads with an
internal relay, which in turn activates the
controls for immediately cutting out the
selected load. As soon as the demand has
been brought down to normal levels, the load
can be normally reconnected. Cooling units,
compresors
and machines that are less important for
production Remember that savings does not
means less work, but rather using resources
efficiently so as to minimize energy costs
and thereby gain a competitive edge.

The New Approach To Production
AIMS At
Maximizing Competitiveness
|
|
To achieve this result it
is not enough to buy energy at the most
convenient price or shut down equipment.
Today, being competitive means controlling consumption and organizing production taking
into account all the parameters that may
impact the cost of the final product.
Businesses and workers have to learn how to
organize their production cycles and examine
every possible and feasible solution.
Those who formulate work plans must make
it clear that turning on equipment a minute
too soon or minute too late may result it
unacceptable cost, Costs. Costs that a
Company must pay. But without an instrument
it is impossible to detect excess loads;
SMART Piu cna monitor and intervene to
optimize energy consumption. SMART Piu is
the right answer to the problem.

Measurement Pages
|
|
Only 4 pages in which to
view three-phase parameters. Furthermore,
the voltages, currents and power factor are
available for each line, as well as the
average and max. average power. Active and
reactive energy are stored in a non-volatile
memory.
The active and reactive energies of
the tree-phase system or, if selected, of
the individual phases, always appear at the
bottom of the display.
|
|
|
|
Other configuration and setting pages are
available together with a guided menu for
easy configuration.
|
|
|
High Resolution Display And Backlit
Display
|
|
80x30 MM, 160 segments, TN technology. Two
measurements parameters displayed at the
same time. Active and reactive energy metes
always displayed.
Immediate access to the menu.
It is also possible to scroll pages up
and down in the SETUP menu for an easier configuration.

|
Special Functions
|
|

|
"Password" Function
The configuration of the SMART Pił,
including the energy meters - is
protected by a safely password. |
|

|
"Partial Energy Meter"
Function
You can rely on a partial energy
meter to measure consumption in preset
periods of time. Resetting the partial
meter will have no effect on the
overall measurements. |
|

|
"Simplified
Configuration" Function
Configuring the SMART Pił is easy:
codes for the three phase, single-phase
and balanced three-phase
configurations are already entered in
the setup menu. |
|

|
"Firmware Update"
Function
The FW version is indicated in a
specific configuration page. In the SMART Pił, the FW is stored in a
"Flash" memory and can be
edited in case of need, directly in
field. |
|
