General function description

Multi-tariffs function

The multi-tariffs function refers to the function that the meter realizes time-sharing measurement of electric quantity. The power meter divides the 24 hours of a day into several time periods, and then specifies the rate number for each time period. Then the power meter accumulates the amount of electricity in time division according to the pre-divided time period, and stores it to the position of the rate number corresponding to each time period, so as to realize the function of time-division measurement of electricity.

The meter used the method of the tariff number correlation to the starting time point to realize the tariff segment division. The power meter support up to 8 starting time points and up to 4 tariff segments (T1, T2, T3 and T4).

Figure 3-1: The starting time points of the tariff segment.

As shown in Figure 3-1, 06:10 designated as the start time of tariff 1 (T1), 12:00 designated as the start time of tariff 2 (T2), 18:00 designated as the start time of tariff 3 (T3), 21:00 designated as the start time of tariff 4 (T4), so tariff 1 time range is 06:10 to 12:00, tariff 2 time range is 12:00 to 18:00, tariff 3 time range is 18:00 to 21:00, tariff 4 time range is 21:00 to tomorrow 06:10.

Note: The tariff parameters can be set by communication commands (Please refer to the relevant communication protocol document for the register address).

Definition of monthly freeze and daily freeze

The JX2121-WI meter provides the statistical function of monthly and daily electricity consumption.
For the time point of monthly freezing and daily freezing, free setting operation can be realized through Tuya APP. The meter can monitor the current time in real time, when the time reaches the set monthly freezing date, the meter will automatically freeze the monthly electricity consumption; when the time reaches the set daily freezing time, the meter will automatically freeze the daily freezing time.The definition of the freezing rule is detailed below:

Monthly freeze rules

The monthly freezing is set by the value of the date. When the time reaches 00:00 of the set date,the meter will freeze the current electricity quantity used and save it as the electricity consumption of the previous month.Ruling definition of month freezing date: the month frozen date is set before 15 days (including 15 days), when the frozen energy is divided into the electricity consumption of the previous month, and the date of the month freezing is set after 15 days, when the month frozen acts, the frozen energy is divided into the electricity consumption of the current month.

Example 2:
The date of monthly freeze is set to 27, assuming the current time is 20:00 on July 26, then when the time reaches 00:00 on July 27, the meter will perform the freezing operation of monthly electricity consumption, dividing the frozen electricity consumption for July (00:00 on June 27 to 00:00 July 27).

Daily freeze rules

The daily freezing is set by the value of the time point. When the time reaches the set time point, the meter will freeze the current electricity quantity used and save it as the electricity consumption of the previous day.

Example 1:
The time of daily freezing is set to 3, assuming the current time is 02:00 on July 5, then when the time reaches 03:00 on July 5, the meter will perform the freezing operation of daily electricity consumption, dividing the frozen electricity consumption on July 4 (03:00 on July 4 to 03:00 on July 5).

Example 2:
The time of daily freezing is set to 20, assuming the current time is 02:00 on July 5, then when the time reaches 20:00 on July 5, the meter will perform the freezing operation of daily electricity consumption, dividing the frozen electricity consumption on July 4 (20:00 on July 4 to 20:00 on July 5).
In accordance with the above freezing rules:
If you inquiry the electricity consumption on July 5 at the period between on 20:00 on July 4 to 19:59 on July 5, the meter will show 0. Because the meter has not reached the daily freezing time point, so the accumulated electricity consumption at this time is still the electricity consumption on July 4.
Inquiry the meter electricity consumption on July 5 at the period between on 20:00 July 5 to 19:59 July 6, then the current accumulated electricity consumption value is displayed.

How to setting the month freeze date and day freeze time
Open the Tuya APP, to find the meter to be set up, click to enter the meter interface , click the setting button in the bottom right corner of the screen to enter the setup interface, click “Frozen Set” on the setting interface, select the month freezing date and day freezing time to be set, click the “confirm” button to set up.

Note:

1. The default month freezing date of the meter is 1th and the day freezing time is 00:00.
2. After reset the freeze date and time, the meter automatically reset data on monthly and daily consumption and then re accumulates.

Alarm

JX2121-WI series products can support the alarm function, which is associated with the inbuiltrelay of the meter. According to the real-time measurement data of the monitored object and the set alarm threshold, if the measured data exceeds the set threshold value, the instrument will automatically disconnect the relay and perform alarm prompt. The alarm function is to compare the measured data of the monitored object with the alarm threshold value every second, to judge whether the alarm threshold value is exceeded, and if it is, the alarm action will be triggered.

Alarm parameter description

1. Alarm monitoring object: the measurement parameters associated with the alarm. The meter compares the data of the measurement parameters every second to determine whether the alarm threshold is exceeded, so as to decide whether to trigger the alarm. The alarm monitoring object supports six measurement parameters. The specific alarm object is shown in Table 7-1 below.
2. Alarm threshold: When the measured data of the monitored object is greater than this threshold, an alarm event will be triggered.
3. Automatic reconnect time of relay: When the alarm event occurs, after the relay is disconnected, the meter will start timing processing, and when the timing time is equal to the set automatic reconnect time, the meter will automatically reconnect the relay.

Note: If the automatic reconnect time for relay is 0, it means that the meter will not automatically reconnect after the alarm occurs, and it needs to be reconnect manually

Table 7-1: Alarm monitoring object

Alarm parameter setting process

Step1: Binding the alarm monitoring object.
Step2: Setting alarm threshold value.
Step3: Setting the automatic reconnect time of relay.

Note: In order to prevent the alarm action triggered by mistake in the process of setting alarm parameters, when entering the alarm parameter setting state, the meter will automatically suspend the alarm monitoring function, and when exiting the alarm parameter setting screen, the meter will  utomatically start the alarm monitoring function to prevent the alarm triggered by mistake.

Alarm action process

After the alarm monitoring object is associated, the meter compares the measured data and alarm threshold value of the monitored object every second, if the measured data is greater than the alarm threshold value, the alarm event will be triggered and executed immediately the following alarm action.

Alarm action of meter:

1. Disconnect the meter inbuilt-relay.
2. The LCD will display the alarm icon:
3. Generates an SOE event and records it to memory

Note:

1. If the alarm monitoring function of two channels is enabled at the same time, the meter will perform the alarm action when an alarm occurs in either alarm channel.
2. when the meter alarm action, if the automatic reconnect function is enabled, when the automatic reconnect time arrives, the relay will automatically reconnect, without manual intervention. If the automatic reconnect time is set to 0, the relay needs to be reconnect manually.
   The operation mode of manually closing relay supports key operation and remote communication operation.
