Tech Support – FAQ

The Power supply option D2 has a range of 90-265 V AC or 100-370 V DC so 277 V AC is about 5% higher than the rated voltage. When used at this higher voltage and in prolonged period of time will have great effect on the power supply that may cause the meter to break down early. It is recommended to seek an alternative 120 V AC regular plug or use a control power transformer to step down the voltage from 480 V to 120 V.

At least one voltage input with a minimum 20 V AC must be connected in it to work. This is “bias” voltage and is necessary for the meter to work properly in CT measurement mode only.

Yes the meter can be used for any single phase application (2 wire or 3 wire). The manual already have an example of the wiring diagram for Dual phase (3 wire) and single phase (2 wire). Please see pages 4-9 to 4-10 for the diagram.

Electrical diagrams on our manual show Low side of the CTs tied up together and connected to ground using CT Shorting Block. The grounding of current transformers is important for safety.

No. You will need our CAB6490 IrDA dongle to do that. The dongle comes already with Windows 7 compatible driver and so driver installation is automatic. The important feature that makes it ‘Standard Modem Over Ir Link” is the most important feature for it to connect seamlessly to the meter using our Communicator EXT software.

Press the scroll down button to go to “W/VAR/PF” screen and then press the arrow right button once to lit the “MAX” LED on the left side. The phase A reading is your Max Demand Watts reading or Peak demand at 15 minute interval (default) settings.

The assumption for the Kh is correct. TV stands for “Test Voltage” or also the voltage input. the Kh unit is Wh/pulse and is expressed in secondary so you need to use the CT ratio and PT ratio to express it in primary. So for example, if the CT is 400/5 and has no PT (120/120) then the CT ratio is 80 and PT ratio is 1. So, the overall factor to be used to multiplied to the number of pulses counted by the PLC is:

Factor = Kh x CT ratio x PT ratio = 0.500017776x80x1 = 40.00

So,
Energy consumption (kWh)= [Factor x No. of Pulses received] / 1000

The default configuration works only with initial meter device profile. This means the PT numerator and denominator and CT num are not changed. Once the CT and PT ratios are changed then you will need to program each channels with high and low output based on primary values of the CT and PT. Programming will need our Communicator EXT 3.0 software and the means to communicate to the meter.

From the Shark 200 Modbus Register Map, the Primary Readings Block Format is Float (or reverse float for most software settings) but for some software that doesnt have the Float format, Integer reads can be used by using the formula,

Modbus = (1st Shark Modbus register x 65536) + (2nd Shark Modbus register + 65536)/65536

Remember that the resulting modbus is expressed in secondary values so to convert into Primary readings use CT ratio for current, PT ratio for voltage and CT and PT ratio for Power.

To reset the energy, write the following command on modbus:

01069CA3xxxx

Where:
01 – is the meter modbus address
06 – Modbus write function
9CA3 – Modbus register in Hex format
xxxx – is the meter password, if not configured, use “15B3” in hex format. This is the default modbus password

Download and save the files into the same folder as the IrDA files.

No. The webpage or webserver of the meter is read-only data.

The Shark 200 – INP100S doesn’t have gateway function thus it is not possible.

Shark meters are ideal for getting the energy readings for loads, generation and even mixed systems that generate part of the time and act like a load part of the time. A good example of the latter is a wind farm. When the wind is not blowing or the propeller is stopped, the wind generator will actually use energy to keep its transmission warm on cold days. Depending on how you have the meter configured and how you orient the CTs you will see energy accumulating in the RCD (Received) or DEL (Delivered) registers. For systems that have both, one value will show up as negative watt hours.

The NET register is the sum of the two values in the RCD and DEL windows. The TOT register is the absolute value of the RCD and DEL registers added together. So, at the end of the month for our wind farm we might see +WH in the RCD window representing the energy that was generated and sent to the grid. We would see – WH in the DEL window representing energy used by the wind generator. The NET would be the sum of the two and this would be the energy that the power company would need to pay the wind farm for. The TOT would be the sum of WH in the DEL and RCD registers representing the total energy in the period.
