ELECTRICAL MULTIFUNCTION METER with LON communication

GENERALITY

These digital multimeters allow to monitor all the electrical parameters

present on a distribution line. The local display of 30 electrical

parameters is carried out by 4 display with red LED guaranteeing a

good and contemporary reading of more measures. A simple front

panel completes the intuitive selection of several electrical

parameters, with a great quantity of information. These instruments,

over of the instantaneous measures, display the maximum peak of the

main parameters (maximum peak and maximum demand).

These multimeters replace in a unique device, all the functions of

voltmeters, ammeters, energy meters, cosphimeters, wattmeters,

varmeters, frequency meters permitting a great economic saving, a

reduction of dimension and the wiring energy and a simplification in

the purchase and management of the instruments because this is a

model usable at all of need of local measure in the electrical panel,

machine, etc.

ELM-96BP-LON instruction manual IM447-U v0.67 pag. 3

For a correct use of the device, the wiring diagram contained in the present manual, must be respected.

The connections are the same for all models and are subdivided in five groups:

- auxiliary power supply:

On the instrument are available 4 terminals to connect the auxiliary power supply to the instrument:

Standard Vac version Optional Vac/cc version Optional Vac/cc version

Terminals Power Supply Terminals Power Supply Terminals Power Supply

1-2 0-110V = 100-125Vac 50-60Hz

1-3 0-230V = 220-240Vac 50-60Hz

1-4 0-400V = 380-415Vac 50-60Hz

1-3 20-60Vac

24-72Vdc 1-3 85-230Vac

90-250Vdc

It’s possible, for example, to take the auxiliary power supply between phase and neutral, in a 4 wires system, or

phase-phase in a 3 wires system, without neutral or from a VT in a medium voltage application.

- measure voltage inputs:

4 terminals are available for the connection to the 3 phase and neutral of the network of measure, the maximum

voltage phase to phase shouldn't be over 500 V rms.

In case of a 3 phase system without neutral, or non distributed neutral to leave terminal N free. In a single phase

connection the phase input 2 and 3 must be connected to neutral.

- measure current inputs:

6 terminals are available for the connection to 3 external amperometric transformers with secondary 5A, it’s possible

to use 2 TA on lines with 3 wires (insertion three phase Aron). The utilization of external TA is obligatory.

With the neutral current input option installed, the multimeter allows the measure of the neutral current, using a current

transformer /5A; the secondary must be connected to the In S1 and S2 terminals available on the rear of the

instrument (see the wiring diagram).

It’s possible, on request, to have the CT input with 1A secondary and the residual (differential) current input using a

specific toroidal current transformer.

- digital outputs:

there are available 2 digital outputs (ON/OFF).

The changeover switch free voltage outputs with common terminal are used to emit pulse proportional to energy and

alarms. It’s possible to use loads up to 230Vac/dc and 150 mA.

- communication LON output:

FTT 10A communication channel

REMARKS: It's a must to respect the phase sequence. The connections between current and voltage phase inputs must not be

inverted (for example, CT placed on phase L1 must correspond to the I1 input). So as it is not correct to invert S1 and S2 terminals,

since power factors and powers might not be reliable.

For fixing the flush mount version instrument to the panel, use the fixing devices supplied, by inserting them in the side groves of the

enclosure and tighten the screws.

For safety reasons, place an external fuse protection at the input voltages, and use adequate cables for the working voltages and

currents, with a cross sections from 0,5 to 2,5 mm2.

Programming of the transformation ratio of the external current transformers (SET CT)

The programming of the CT ratio, intended as the ratio between the primary and the secondary circuit (example: with

CT 1000/5 it must be set 200), has to be performed by using the front keys.

After the enter in the setup (message SETUP on Fdisplay) pressing the Ckey, the message seT will appear on the G

display and the message CT (Current transformer ratio) on the first Fdisplay; the transformation ratio value (set to 1

by the manufacturer) on the second and the third Fdisplay. Press Bor Ckeys to increase or decrease the value

respectively (the variation is performed unit by unit). In order to speed up the operation, keep the Bor Ckey pressed,

the variation will be performed by tens and hundreds. To increase or decrease the value by unit, it is necessary to

release and to press the button again. To confirm the set value, press the Abutton; in this way it is possible to enter

the next programming. If none key is pressed for 10 seconds, the instrument will automatically leave the programming

menu and the eventual setting SHALL NOT be stored.

- Programming of the transformation ratio of the external voltage transformers (SET VT)

After the precedent programming phase, on Fdisplay will appear the inscription Vt (voltage transformer) and the value

of the transformation rate of the external TV (set to 1 from the constructor), considered as the rate between primary

and secondary (example with TV 15/0.1 kV the value will be 150). In the same way at the programming of the CT rate

will be possible to set this value. If the external TV are not used the value to set will be 1. To confirm the value press

the Abutton.

If the instrument has not options the programming continues with the set of average time AVG T’ and after with the

password PASS, then it come back at the first page SETUP. The presence or the absence of the options, neutral

Programming of the transformation ratio of the current transformer for the neutral current input (CTN)

(version with neutral current input)

This setting is active only for the models with this option installed; the message SET will appear on Gdisplay; the

message CTN (Current transformer neutral ratio) and the set value on the Fdisplay. In the same way at the

programming of the CT rate will be possible to set this value (example with CT 1000/5the value will be 200).

Pressing the Akey, confirm and go away with the next setting.

Programming of the average time (seT AVG T’)

After the programming phase previously described, pressing another time the Akey, on the Fdisplay will appear the

message AVG T’ and the average time settable from 1 to 30 minutes.

To increase the value press the Bkey. To decrease it, press the Ckey. To confirm it press the Akey.

The average time is the time used to calculate the average parameters (avg) and the maximum demand (maxD).

Programming of the energy visualization type (seT EN)

This setting allows to define the energy visualization type.

With TOT PAR will have the visualization of the partial and total energy counters; With NORMAL there will be only the

visualization of total counters.

Programming insertion mode (3PH)

In aunbalance three phase system it’s necessary to set UN_BAL (unbalance) while in abalance system (only one CT

and only one VT) the correct set is BALANC (balance). For asingle phase insertion it’s necessary to set 1PH L1.

Programming wiring connection mode (MDE)

This setting allows to definite the wiring type connection. It’s possible to chose 3 wires or 4 wires. With the 4 wires

connection the neutral parameter are displayed and enabled to use for the digital outputs settings.

Programming of the synchronism type (SYN MDE)

In this setting for the synchronization type, it’s possible to choose L1 to use the external frequency (on L1 phase) or

50, 60 Hz to use the internal clock.

Programming of the weight of the active and reactive energypulse (seT PULSE) (only for vers. withdigital output)

After the above mentioned programming, by pressing the Akey again, the message PUlse will appear on the F

display and the value of the weight of one pulse settable on three phase values: 0,01 - 0,1 - 1- 10 kWh or kVArh (for

each emitted pulse the instrument will have counted 0,01 - 0,1 - 1 - 10 kWh o kVArh).

Press the Bkey to increase the value or Ckey to decrease the value and Ato confirm.

Programming of the duration pulse (SET TPL) (only for vers. with digital output)

The message TPLwill appear together the value of the duration pulse expressed in mS. It’s possible to select the

value from 100 mS to 500 mS, with 100 ms steps by using Bkey (to increase the value) and C(to decrease the

value). Confirm the value pressing the Akey.

This setting is used by all digital outputs.

Programming of the Password (SET PAS)

The instrument is supplied without password. When a password (from 0002 to 9999) is set, using the B(to increase),

C(to decrease) and A(to confirm) keys, only who know this value can to enter in the setup. The password, in fact, is

required all the time that someone try to enter in the setup (pressing the Aand Bkey at the same time). If the

password is wrong, the message PASS ERR will appear on Fdisplay and the instrument go back to the measures

visualization. To input the password, when required by the instrument, at the enter of the setup, use the A, Band C

keys as the same way done previously.

The menu is cyclic. After the last setting, the instrument go back to the first page of Setup (SETUP). It’s always

PROGRAMMING OF THE DIGITAL OUTPUT (SET DO1 SET DO2)

The DO1 and DO2 digital outputs have three modality of functioning: PULSE, alarm (ALR) and REMOTE command.

The DO1 modality setting is independent from DO2. For example it’s possible to set DO1 on PULSE (pulse emission)

and DO2 on alarm mode (ALR).

In the menu SET DO1 and SET DO2 it’s possible to program the function of all digital outputs. In these menus are

available the following modality: PULSE, ALR and REMOTE.

In PULSE mode the digital output DO1 will emit pulses proportional to the active energy counted while the digital

output DO2 will emit pulses proportional to the reactive energy counted. The proportionality will depend from the

PULSE set in the SETUP and the duration of the impulse is set in the TPL voice of the SETUP.

The ALR modality is divided in two parts: ALR SYS 3PH and ALR SYS 123. With ALR SYS 3PH the digital output will

function as alarm verifying that the three phase value doesn’t exceed the threshold set (ALR HI and ALR LO). With

ALR SYS 123 the digital output will function as alarm verifying that the maximum value of the single phases doesn’t

exceed the maximum threshold set (ALR HI) and that the minimum value of the single phases doesn’t come down the

minimum threshold set (ALR LO). The activation of the alarm output will come after some seconds of delay set(ALR

DL).

In REMOTE mode, the LON variable define the status of the output.

led on the Dbar. Press Akey to confirm the set.

SET THE HIGH AND THE LOW THRESHOLDS

On Fdisplay will appear the message ALR Hi with the high threshold value; confirming with the Akey on the same

display will appear the message ALR LO with low threshold value. The B(to increase) and C(to decrease) keys are

used to set the high and the low thresholds values. The range depends by the parameter and it is linked to the CT and

VT ratios. Pressing Akey to confirm.

The threshold set is linked with CT and VT ratios, for this reason it’s necessary to make this operation after the

programming of the CT and VT. The end scale value must be confirmed when CT and VT ratios are modified.

The low threshold will be lower than high threshold. If the high threshold is set as OFF the low threshold will have the

range of the high threshold.

SET THE DELAY TO THE DIGITAL OUTPUT ACTIVATION

Now it’s possible to set the delay that will pass between the alarm condition set and the activation of digital output. On

Fdisplay will appear ALR DLY and the value expressed in seconds (range 1÷900). The modification of the value is

done in the same way of the threshold set. With the confirmation (Akey) the set is complete.

MEASURES VISUALIZATION

The instrument is divided in two distinct section:

the first is composed by three displays (F), by Aand Bkeys and by

LED bar D; the second (in the low part) is composed by Gdisplay,

by Ckey and by LED bar E.

The two sections are to consider as two different instruments in a

only one box, in fact it’s possible to act in a zone without to modify

the visualization in the other (peak value and energy counters

visualization excluded).

Visualization section 1

The three measures of phases (on L1, L2 and L3), of the parameter

indicated from the led Don, appears on Fdisplay. For the measure of the phase to phase voltages (V L-L), the three

measures are V L1-L2, V L2-L3, V L3-L1.

It’s necessary to press the Bbutton to select the parameter that can be displayed and indicated from DLED.

Press Abutton to see on Fdisplay the three phase value (the average of the single phase of voltage, current, power

factor and the sum of single phase for the power) of the parameter selected,: the led inside the Akey is on.

To press another time the same key the visualization come back at the phase values.

The unit of measurement can be expressed in kilo or Mega, in the this case the relative LED is on.

A sign – on the first digit indicates the visualization of the capacitive power factor (example the reading -.95 indicates

a power factor of 0.95 capacitive)

Note: If in the Setup the single phase mode (1PH L1) is set, all the measures appear on the L1 display.

Visualization section 2

At the same way of the section 1, press the Cbutton to select the parameter that can be displayed and indicated from

ELED. The voltage values are of the three phase system, the frequency is of the L1 channel.

Visualization energy and hours counters

With the Ckey it’s possible to visualize on Fdisplay the active, reactive and apparent energy counters. One segment

of the right digit of the Gdisplay, in correspondence of the kWh and KVArh on the front panel, turn on, to indicate the

visualization of the active and reactive energy counters. The led VA and the segment of the right digit of the Gdisplay,

in correspondence of …h on the front panel, turn on, to indicate the visualization of the apparent energy counter. To

complete the visualization the led kover the Fdisplay could be on.

This is the visualization if NORMAL is the set in EN voice of the setup. Instead if the setting is TOT PAR on the F

display will be visualized alternatively the partial and the total active, reactive and apparent energy counters; the first

digit of the Gdisplay indicates the type of the counter: Pfor the partial (the user could be reset it) and Tfor the total

(it’s no possible to reset it).

The right digit of Gdisplay, in correspondence of the …h, turn on, when the visualization of hours counters is active.

The reading of the counters use the 9 digits (maximum reading 99999999.9) of the Fdisplay: the measure is

displayed in the way that the L1 display will indicate the first 3 digits, the display L2 the seconds 3 digits and the L3

display the last 3.

For example if: L1=000, L2=028, L3=53.2 the reading is 2853.2 kWh.

ELM-96BP-LON instruction manual IM447-U v0.67 pag. 12

VISUALIZATION PEAK AND AVERAGE VALUES

Pressing at the same time the Aand Bkeys, on Fdisplay will appear the

average and maximum stored value, that are selected using the Bkey while

a luminous segment on the Gdisplay indicates the type of the maximum

and/or average value.

AVG: the average values are calculated on a average time set. The

calculation is at fixed window and it’s sinchronized when the instrument turn

on.

The stored maximum values are the two types:

MAX: the instantaneous maximum values store the maximum value

achieved by the parameter of measure for at least one second.

MAX AVG: the average maximum values (maximum demand) store the

maximum value achieved in the average time as set in the setup menu;

The integration for the calculating of the average values is synchronized all the time that the instrument turn on.

Press Aand Bkeys another time to come back to the measures visualization. The instrument will come back to the

measure visualization automatically if for 10 seconds no one button is pressed.

The average value, the maximum value and the maximum average value selectable with Bkey are the following:

The refresh time of the display is lower of a second and it depends by the time of calculating of the measure and concerning the

methodology of measure used in the way to allow a comfortable reading of value also in presence of fast variation of the measure

parameter.

If the multimeters are used on single phase lines, the measures are referred at the phase L3. The other data displayed and relative

to the three-phase system must not considered.

If the measure indicated by the instrument are not reliable or absurd it’s necessary to verify the connection of the measure inputs of

currents and voltages because must be respected the sequence of the phase, the corresponding of the currents and voltages of the

same phase (the L1 voltage phase and the TA located on L1 phase must be connected on the L1 input) and the sense of the

current (the S1 terminals of the TA must be connected at the S1 terminals of the instrument).

In some application where the secondary is connected to other instruments apart from the ELM multimeter, some problems could

happen concerning the typology of the amperometric inputs.

If there are some problem call the assistance service.

The nvo_IO_State is a 16 bit variable. The bit have the following meaning:

•Bit 0 DO1 state

•Bit 1 DO2 state

•Bit 2 Input state

Service Led: If the “decommission” instrument will be connected to a LON network, the Service Led must have a regular blink (the time with Led ON it’s similar to the time with

Led OFF). After the “commission” operation, during the normal functioning, the Led must remain OFF. If the Led works in a different way, the instrument could have some

problem. In this case it’s better to send the instrument to the Service Center.

Service Push-Button: It’s used to “commission” the instrument. “Commission” mean to give a logic address in the LON network in the way to allow the communication with other
