TX Pulse
Connecting smart metering sensors to meters
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
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
Indicator light
Locate the flashing diode on the meter. It is on this diode that the optical reader will be positioned. The optical read head can only interpret LED flashes with a flashing duration of 3ms minimum and 100ms maximum.
Viewfinder attachment
Clean the meter around the flashing diode. Glue the viewfinder by aiming the diode through the hole (the viewfinder has adhesive)
Drive lock
Clip the reader into the viewfinder. Exert a uniform force over the entire surface of the sensor.
Checking
Once you power your transmitter, the red LED will light up periodically for 20 seconds, then the green LED will take over.
