Any one of the lights "U1, U2, U3" and the three lights "UN" and "V" are on at the same time, indicating the corresponding phase voltage
The "HZ" light lights up to indicate the frequency. If no voltage is connected, the default is 50Hz.
The "COS" light on indicates the power factor.
The "KW" light on indicates active power.
The "KW" light flashes to indicate active charging, and the unit is kilowatt-hours.
3. Self-diagnostic fault identification
When the "T" light on the control panel lights up, it means there is a self- diagnosis fault. Press the OK key to display the fault code.
If the fault is cleared, press the return key to clear the self- diagnostic fault“T" light and return to normal status; if there are multiple diagnostic faults, press the▲and▼keys to cycle through the fault codes. The fault code is as follows:
As shown on the controller panel, the controller has the following various states during operation;
1. Setting status: The "Setting" light is always on, and the setting values of various protection characteristics can be viewed or modified.
2. Query status: The "Query" light is always on, and historical fault information can be viewed.
3. Test status: The "test" light is always on, and the trip test can be performed.
4. Fault status: The "fault" light is always on, indicating the fault type, and the fault current and time are displayed in a loop.
5. Alarm status: "Alarm" light flashes, indicating that it is in the process of fault delay.
6. Storage status: The "storage" light flashes once, indicating that a data change has occurred.
7. Self-diagnosis status: "T" light is on, indicating that the controller has a self- diagnosis fault.
8. Communication status: Only H type has it. The "Tx, TR" lights flash, indicating that there is data transmission.
Operating the function,▲,▼, OK, return, and other keys on the controller panel can realize setting, query, and test functions. Press the function key to cycle through three states: setting, query, and test; pressthe▲and▼keys to select function items or increase or decrease parameter values; press the OK key to enter the function state or store the changed data; press the return key to return to the previous page. Level 1 operation. The various protection characteristic setting settings should ensure I.>I.>lg. and it is recommended that lLc1> ILc2. The operation steps are as follows:
Step 1: Press the function key until the "Settings" light flashes, and press the OK key again. At this time, the "Settings" light still flashes, and a certain protection category The light is on, indicating that it has entered the setting value setting state.
Step 2: Pressthe▲and▼keys to cycle through the original setting data of various setting values. If you want to modify a certain setting value, press the OK key,At this time, the "Set" light is always on. Use the▲and▼keys to adjust until the required value is reached. Press the OK key. The "Save" light will light up once, indicating that the modification has been saved.changed data. Press the return key to exit the modification of the setting value.
Step 3: Repeat step 2 until all setting values are modified. Press the return key to exit the setting function.
When modifying the setting values of various protection characteristics, please refer to the following two tables:
