Connecting smart metering sensors to meters
TX PULSE sensors can be wired in three ways:
The TX PULSE and TX PULSE ATEX sensors are compatible with meters with pulse outputs in dry contact or open collector.
Pulse duration = 50ms minimum Pulse frequency = 10Hz maximum
Installing the optical read head on the meter
The pulse optical reader records 1 pulse every 5 flashes.
Calculation formula = (A x 5) x B x C x D
A = Number of pulses measured
B = Pulse weight Blue tariff: 0.1W/pulse. In this case, enter 0.1 for B value in the calculation below. Other tariffs: Shown on the meter’s interface (label or screen)
C = TC ratio (Current transformation) Blue tariff: 1
Yellow tariff: 20, 40 or 100 (shown on the meter’s interface)
D = TT ratio (Tension transformer)
Blue tariff: 1
Yellow tariff: 1 Green tariff: Shown on the meter’s interface.
The calculation formula above is a calculation of consumption in Watt-hour (Wh). To get a value in Kilowatt-hour (kWh), you just need to divide the value by 1,000
Viewfinder attachment
Locate the flashing diode on the meter and stick the viewfinder aiming the diode through the hole.
Locking the reader
Clip the reader into the viewfinder. Exert a uniform force over the entire surface of the sensor.
Fixation
Use the black screw to tighten the optical head to the viewfinder
Checking
Validate the correct positioning of the optical read head before powering the sensor
