Switching output is relay output, can achieve the remote-control and alarm output.
The switch input adapts the method of on-off signal input and powered by outer power supply.
It can be gotten by meter when there is a change of on or off via a switching input module. The
parameter of switching input can not only get and show the state of local switching information
but also achieve the communication via RS485, which called “remote information” function.
Note: (17-18) are active energy pulse, (60,61,62,69) are NTC temperature measurement port,

7 Function description
7.1 Measurement
The meter can measure all electrical parameters such as voltage, current, active power,
reactive power, apparent power, power factor, frequency, 31st harmonic and total harmonic. The
value format of voltage, current, frequency and power are listed as below.
Example: U = 220.1V，f = 49.98Hz, I = 1.99A，P = 0.439kW

7
7.2 Calculating
The meter can calculate the current active energy, forward active energy, reversing active
energy, forward reactive energy and reversing reactive energy.
7.3 Timing
The meter has 2 time lists, and can be divided into 4 time zones per year. Each time list can
be divided into 8 time periods and 4 tariff (F1、F2、F3、F4). The main purpose of multi-tariff is
promote the energy efficiency and economic benefits.
7.4 Demand
There are some definitions on demand:
Demand
The average power in the demand cycle.
Maximum demand
The maximum value of demand in a period of time.
Slip time
A recurrence method to measure the demand from any time point
during a period shorter than the demand period. The demand
measured by this means is called sliding demand. The recurrence
time is sliding window time.
Demand cycle
The time period between two same average value of demand.
The default demand cycle is 15 minutes, slip time is 1 minute.
The meter can measure 4 kinds of maximum demand: forward active, reversing active,
inductance performance reactive, capacitance performance reactive maximum demand and the
occur time.
7.5 History data statistics
The meter can record last 48 months or last 90 days history energy in each tariff.
7.6 Switching input and output
The switch input adapts the method of on-off signal input and powered by outer power supply.
It can be gotten by meter when there is a change of on or off via a switching input module. The
parameter of switching input can not only get and show the state of local switching information
but also achieve the communication via RS485, which called “remote information” function.
7.7 Temperature measurement
The meter support three path of outlay NTC temperature measurement, the range of
temperature is -40℃~99℃.

8.2 Display menu
The meter will show the forward active energy after powering. The customers can change the
information showing by pressing the keys. The menu description is listed as below:
Voltage on A, B, C phase, Current on A, B, C phase, Frequency, Date, Time,
Address, Version, Test on display
Total active/reactive/apparent power and on A, B, C phase, Total power factor and
on A, B, C phase, Forward/reversing active/reactive maximum demand
Total forward/reserving active/reactive energy, forward/reserving active/reactive
spike/peak/flat/valley energy, forward active energy on A, B, C phase.
Note:
1 All the display menus above are in the model of ADL3000-EF three phases four lines with
multi-tariff rate function and can be changed by the keys.
2 There will not be power or power factor on each phase and will only show total power and
power factor (Active, reactive, apparent) under the three phase three lines.
3 There will not be date, time, maximum demand and energy by time without the function of
multi-tariff rate.
Current forward active energy 12.34kWh
Current reversing active energy 12.34kWh

Current forward reactive energy 12.34kWh
Current forward active spike energy 12.34kWh
Current total power is 1.234kW
Current forward active demand is 1.234kW
Voltage on A phase is 123.4V
Current on A phase is 12.34A
Temperature on T1 is 25.5 cent degree
Temperature on T2 is 25.5 cent degree

10
Temperature on T3 is 25.5 cent degree
Note: There are parts of the display function, and other menus are familiar with the example above.
The customers can understand the meaning refer to the above examples.
8.3 Key Menu
Press at any main menu and get in “PASS” interface, and then press show
“0000”, and enter the code. If you enter a wrong code, it will show “fail” and back to main menu;
and if you enter a right code, you can set the parameter. After setting the parameter and
press , it will show “save” and save the change by pressing in “yes” interface and
quit without save by pressing in “no” interface.

9 Communication description
The meter adapts MODBUS-RTU protocol, and the baud rate can be chosen from 1200bps、
2400 bps、4800 bps、9600bps and 19200 bps. The parity is None.
The meter needs shielded twisted pair conductors to connect. Customers should consider the
whole network’s parameters such like communication wire’s length, the direction, communication
transformer and network cover range, etc.
Note:
Wiring should follow the wiring requirements;
Connect all the meter in the RS485 net work even some do not need to communication, which is
benefit for error checking and testing;
Use two color wires in connecting wires and all the A port use the same color.
No longer than 1200 meters of RS485 bus line.
