Characteristics
LS (LED sensor)
• The LED sensor scans LED impulses on the meter, which indicates consumption by fl ashing.
• The LED sensor is particularly suitable for power meters that support LED pulse sensing (the LED on the meter is marked "imp").
• The sensor's scanner is affi xed with glue above the LED diode of the meter signaling indication of consumption.
• The sensor is connected to the internal terminal of the RFTM-1 converter.
MS (Magnetic sensor)
• The magnetic sensor scans movement of the numeral, upon which a permanent magnet is placed.
• The MS sensor is particularly suitable for gas meters that support magnetic sensing.
• The sensing sensor is glued over the last number of the face dial measured.
• The sensor is connected to the internal terminal of the RFTM-1 converter.
WS (magnetic sensor water meter)
• A magnetic sensor that detects the pulse that is created by each rotation of the magnet placed on the unit dial meter.
• The WS sensor is especially suitable for water meters that support magnetic sensing.
• The sensing sensor is glued over the circular unit face of the gauge (the scanning dial is diff erent from the other indicators, e.g. the white arrow wheel).
• The sensor is connected to the internal terminal of the RFTM-1 converter.
Output S0
• The meter generates a certain number of impulses (typically between 250 and 10000 imp / kWh), with S0 output being switched to the pulse of these pulses. The same
is true for water meters or gas meters.
• S0 output is a controlled switch that switches to the pulse rhythm bound to the current consumption.
• It is necessary to distinguish the terminals S0+ and S0-, see wiring.
• Pulse output can be made in the form of terminals or output cable (water meter, gas meter).
Positioning the Sensing Sensor on the Meter
Position of the
switching circuit
Clean the sensor surface (depending on the sensor type) and attach the sensor. On the RFTM-1 blinks red LED when the pulse is detected.
Attach the sensor to the scanning position. The cable must be loose. Check the scanning accuracy.
The sensor does not eff ect meter consumption, nor does it interfere with the reading measurements the meter makes.
Notice:
Electricity meters, water meters and gas meters are the property of energy suppliers. Without their knowledge and permission, you are not allowed to interfere with the internal
connections (seals, supply lines, etc.).
