The indicator is designed to work with current transformers with primary current Ip from 5 ├Ě 6000A and secondary current 5A. The maximum measured current is determined by the value of the primary current Ip current transformer used. You can set the index value of the gear used transformers, allowing you to identify the actual value taken by the electricity system.
A special electronic system under the influence of current flow and applied voltage in each phase generates pulses in proportion to the electricity consumed in this phase. Phase energy consumption is indicated by flashing the corresponding LED (L1, L2, L3). The sum of the three phases of pulses indicated by a flashing LED is converted to energy taken in the entire three-phase system, and its value is determined by the segment LCD display.
Stored in the memory index values transformer primary current Ip possible to apply. Choosing the right value compatible with the values of external transformers automatically sets the correct ratio, which is calculated according to the actual value of the collected energy. The LCD displays the actual value of the energy consumed in the format depending on the selected gear.
Pulse output SO
The indicator has a pulse output SO+ SO-. This allows you to connect a pulse meter-reading (SO) pulses generated by the counter. For proper operation of the indicator is not required to connect additional devices. Constant pulse counter is 12000pulses/kWh for maximum input current meter, or the secondary current transformer (5A). When using a dedicated transformer the number of pulses per 1 kWh is calculated from the formula (12000 ├Ś 5) / Ip, where:
Ip - primary current transformer used.
for a transformer of 5 / 5A (Ip = 5): (12000 ├Ś 5) / 5 = 12000pulses / kWh
for CT 100 / 5A (Ip = 100): (12000 ├Ś 5) / 100 = 600pulses / kWh
Transmission programmable using the button located under the lower casing meter terminals.
For safety reasons, the data logging function can make the gear set only once.
CT Current values Ip inscribed in memory device:
5, 25, 40, 50, 60, 75, 80, 100, 120, 150, 200, 250, 300, 400, 500, 600, 800, 1000, 1200, 1500, 1600, 2000, 2500, 3000, 4000, 5000, 6000.
Another pressing the programming button jumps to the next value.
After switching to the desired value in order to confirm the selected value to hold the key >30s.
