7. MAIN FEATURES
7.1 Consumption indication
On the front panel, there are five LED’s. 1. Line 1 2. Line 2 3. Line 3 4. Reverse Current 5. Active Energy Pulse Light.
7.2 Reading the meter
6+1 LCD display is used for recording energy reading and the system cannot be reset to zero. Each digit is based on 10 units
and each unit is in kWh.
When switched on, the meter will run through all the current default settings. Each screen will display for 1 second.
Rs485, PC software or a hand-held unit can also be used to read the power consumption

7.3 Pulse output
Smart din rail energy meter is equipped with a pulse output which is fully separated from the inside circuit
.
That generates pulses in proportion to the measured energy. They are test pulse output (pins 23&24).
Usually, the test pulse output is used as testing accuracy or reading purpose in close quarters.
, passive transistor output requiring an external voltage source for
THE TEST PULSE OUTPUT IS A POLARITY DEPENDANT
correct operation.
For this external voltage source, the voltage (Ui) should be 5-27V DC, and the maximum input current (Imax) should
be 27mA DC.
To connect the impulse output, connect 5-27V DC to connector 25 (anode), and the signal wire (S) to connector 24 (cathode).
The meter pulses is indicated on the front panel.+
7.5 Communication port
Smart meter has equipped communication port, we can program the meter’s
operation data or reading via these 2 ports (Pin26 pin27).
There are two options for the communication com, Rs485 or M-Bus
