Mult-K Grafic Multifunction and Consumption Energy Meter

Knowing the Product

Installing the Product

Accomodate the meter on the panel cutout and fasten it using the side locks Ⓓ. Panel’s cutout dimensions must be 92x92mm

Power Supply Connection

Power Supply signal must be applied to the Ⓔ terminal block. Cabling must be connected in accordance to the power supply option present in the meter.

Selectable AC Voltage (220 or 120 Vac)

ATTENTION
Pay extreme attention to the type of auxiliary power supply of your meter.
Incorrect cabling connection or applying a voltage signal above the specified limits can damage it severely.

Voltage Input Connections

Connect phases and neutral references to the Ⓕ terminal block, using the order described below:

Measurement Range: 20 to 500Vac Ph-Ph 11,54 to 288,67 Vac Ph-N

Current Input Connections

Connect phase references to the Ⓖ terminal block, using the order described below:

Measurement Range: 20mA to 5Aac (Continuous Overload: up to 7.5Aac)

Accessing Operation Modes

Mult-K Grafic’s Man-Machine Interface is composed of an LCD display and three navigations keys – F1, F2 and F3. The navigation keys can assume diverse functions, which are always presented in the lower navigation bar. To access the intended function/command, the user must press the related key. The lower navigation bar will fade after ten seconds of no interaction with the analyzer.
Instantaneous Measurements: Initial and main mode of the analyzer, which allows access to other modes and the checking of V, A, W, VAr, VA, PF, Hz and THD values. In this mode, use the << and >> keys to navigate through the measurement parameters.
Energy Measurements: checking of kWh+, kWh-, kVArh+ and kVArh values. To access it, with the analyzer in the main mode, press any key. Then, press repeatedly the MODO key until the ENERGIA message appears on the ENERGIA right side. After that, press key.
Configurations : configuration of constants for PT and CT, connection diagrams, integration time (demand), communication, power quality parameters, and reset commands (energies, demands and voltage measurement campaigns). To access it, with the analyzer in the main mode, press any key.

Configurations mode

The following commands will be available when Configurations mode is accessed:
EDITAR: Editing of the currently selected parameter.
PROX. : Navigates through the pages of the configurations mode.
ALTERA : Confirms the changing of the highlighted parameter.
VOLTAR : Sends the analyzer back to the prior screen.
DEC : Decrements the active digit.
INC : Increments the active digit.
> >  Navigates through the available options of a selected menu.
SAIR :Returns to the main mode, leaving the configurations mode.
Below, menu descriptions and default settings of Mult-K Grafic:

Example: PT — 440/220V, PT ratio = 0002.00
Current Transformer Ratio
Example: CT –1000/5A, CT ratio = 0200.00| 0001.00
0001.00
2| KE
TI.| KE (Pulse constant)
Constant that determines the pulse rate of the related output, in Wh. This parameter needs to be configured only when the analyzer has this feature and its value must be always a TP x TC.

FAQ – Frequently Asked Questions

a. The Mult-K Grafic doesn’t turn on
Check if the connection to the terminal block Ⓔ was made as stated in step ❸ and also if the voltage magnitude applied is within the working range for meter´s power supply.
b. Measurement values seem incorrect
Check if voltage and current connections are corresponding to each other, i.e., each meter’s channel with the same reference indication – Example: (Va, Ia – Ia) – must receive signals from the same phase, as stated in steps ❹ and ❺. Also check if the polarity of CTs is correct (Correct Installing, Primary side: (LINE) P1 – P2 (LOAD)| Secondary side, S1 connected to Ix S2 connected to Ix).
