VMKThe meter can be configured on site for various parameters including Nominal Voltage, Current Full scale Setting, Current Shunt Settings, Demand Integration Time, etc.The front panel has three push buttons using which the user can scroll through different screens & configure the product. It also includes 12 LEDs which in conjunction with LED display, provides information in different units and gives the status.
1.Introduction
The Multifunction DC Energy Meter is a panel mounted 96 x 96 mm DIN Quadratic Digital Panel Meter, which measures important electrical parameters in DC Network and replaces the multiple analog panel meters. It measures electrical parameters like DC voltage, Current, Power, Energy (Import & Export), Demand & many more. The meter integrates accurate measurement technology with bright LED display (8 digit x 1).8 digit x 1seven segmentLED displayParameterLEDsMultiplierLEDsBi-color LED(Red & Green)/Status LEDDown keyUP keyEnter key4

2.Measurement Reading ScreensIn normal operation, the meter shows one of the measurement reading screens out of several screens. These screens may be scrolled through one at a time in incremental order by pressing the “UP key” or in decremental order by pressing the “DOWN key”.The Status LED serves many purposes. In measurement screens, it changes color according to load status i.e. healthy, alarm and overload conditions. Overload condition is defined as measured value > 126% of nominal value. Refer the following points to decode the information that the LED provides. These points are true for measured parameters i.e. voltage and current. The Status LED glows green in healthy condition and becomes red in overload condition. If a limit relay is assigned, the LED will glow red if alarm condition is true and will glow green if healthy condition is observed.For derived parameters (power, energy, ampere-hour and demand), following points are applicable. When the voltage and current both are healthy, the Status LED will glow green. If one of the parameters (voltage or current) is in overload condition, Status LED for all the derived parameter calculated from that value will also turn red. If a limit is assigned to the parameter, the Status LED will glow red in alarm condition and green in healthy condition.When more than one from the above conditions are applicable, the Status LED will follow "OR" logic for alarm condition and "AND" logic for healthy condition, i.e. it will glow red when even one of the alarm conditions is true and it will only glow green when all of the healthy conditions are true.36There are two multiplier LEDs marked K (kilo: 10) and M (mega: 10). Each will glow red according to the scaling required to the value on display.One or more from the parameter LEDs will glow red according to the parameter displayed on the screen.5

(As shown in screen 2)An example of the power screen is shown in the picture.The Status LED is glowing green which means it is in healthy condition. (As shown in screen 1)The Status LED is glowing red and a measured value is being displayed, which means one from the following conditions is present. (As shown in screen 2)1) There is a limit relay and alarm condition is present.2) Any one from voltage or current is in overload condition.StMKOldImpExpDmdWAVhrOldImpExpDmdWAhrOldImpExpDmdWAhrImport Energy ScreenStMKOldImpExpDmdWAVhrOldImpExpDmdWAhrOldImpExpDmdWAhrStMKOldImpExpDmdWAVhrOldImpExpDmdWAhrOldImpExpDmdWAhrImport Energy Overflow ScreenShown above screens are the import energy screens. The display of the meter can only accommodate 8 digits. So to display more than 8 digit energy, an overflow screen is added. When the energy reaches the energy digit reset count, it starts the count from 0 again. When this happens the corresponding overflow is increased by 1.StMKOldImpExpDmdWAVhrOldImpExpDmdWAhrOldImpExpDmdWAhr6

Number of cycles - The maximum value of the overflow is 2000. Thus the highest energy that the meter can show is 200099999999 Mwh.To obtain the value for current energy reading, the user need to multiply the overflow count by 10 raised to energy digit reset count and add the result in displayed energy reading.Example: In the screens shown above, assume that the energy digit reset count is 8 respectively. So the energy reading will be as following:8[(100 x 10) + 5030 ] = 10000005030 WhThe overflow value will start counting from 0 after reaching 2000.Note: - DC EM measures positive & negative Voltage, Current and it's derived parameters.
2.1 Timer Screen
There are two timers : tMr1 and tMr2. Each separate screens for the three parameters of each timer namely, number of cycles, on delay and off delay present in measurement screens are shown in above pictures. Each parameter screen toggles between its parameter name and its parameter value every 3 seconds. When timer is running, these values are shown in countdown mode. If number of cycles is set as 0, then the number of cycles will always increment from 0 up to 9999.Note : - 1. Long press UP key to start any timer. 2. Long press down key to stop any timer.Timer Unused : - Timer is not selected as a relay output. This screen shows the number of power supply interruptions that the meter has encountered. After 9999 this value will start it's count from 0. User can reset this count in the reset menu. This screen toggles between its parameter name & its parameter value every 3 sec.

This screen shows the total number of hours the auxiliary supply has stayed on. Even if the Auxiliary supply is interrupted count of on hour will be maintained in internal memory & displayed in theformat. For example if displayed “hhhhhh.mm” count is 105000.10 it indicates 105000 hours and 10 minutes. After 999999.59 On hours display will restart from zero. The user can reset this value in reset parameters menuAs shown above the parameter screen toggles between its parameter name & its parameter value every 3 seconds..
