Mode selection
Timed charging

Add timed charging: If you choose on, you can set the start time and charging duration. If you choose off, you can only set the time to stop charging. After the setting is successful, it is not recommended to cancel the timing within one minute before the time point set for the timing. Due to the delay of cloud processing, it may fail to cancel. If this extreme situation occurs, it is recommended to check the charging status on the main page to confirm that the Charging station is closed. If the timing cancellation fails, the Charging station. suntree-SWJ3E-7-Electric-Vehicle-Charger-

Setting of TUYA APP

DLB function

Optional function, which is a power management function, can selfadjust the output current so that the total household electricity load does not exceed the total household current. CT is installed on the tiring line of the household main incoming line (or for three-phase power, each live wire needs to be installed with a CT), and the current output is detected in real time to adjust the output current of the charger in real time.
The total current of HOME incoming line can be set through the APP, and the path is “TUYA -APP home page – Setup – Card Binding – Command input”. Enter “HOME value” in the command input field and confirm to complete the setting of the upper limit of the total current of HOME incoming line, and the input value is the upper limit. suntree-SWJ3E-7-Electric-Vehicle-Charger-
fig-41

Note:

If the current values of three firing lines detected by three-phase power are not equal, the product will self-calculate the minimum output current, and the three output lines will be executed according to this minimum output current.
When the DLB is not installed, the charger will output with the maximum allowable current, which is fixed and will not be adjusted automatically unless adjusted by external control.
DLB Function:
The current value of the home + the current value of the charger exceeds 2A of the total current of the home line, and the current value set by the charger is greater than the actual current value of the charger. In this case, DLB is adjusted. For example, set the total current of the HOME incoming line “HOME 32A” (the charger actually takes the maximum current value of -5A as the maximum input value of the HOME, so as to prevent load balancing failure and reserve 5A). Therefore the total current of the HOME incoming line is 32A- 5A=27 A;
The default charging current of the charger is 32A, and there is BA load in the family. At this time, the theoretical current value is: 32A+8A=40A, which exceeds the total allowable value of the family (27 A) 13A, and the current of the charger will decreases by 13A to 19A. When the condition current of DLB changes for more than 2A and lasts for more.

RFID Function
The charger has a card swiping board inside, through the external card swiping to implement the device starting and stopping vehicle charging. (Enter the 16-digit card number in the APP card binding page, and bound the RF card).

Troubleshooting

Fault Codes and Solutions

Failure	Solution
Leakage self-test	Check whether the leakage transformer is connected normally

After the leakage transformer is connected normally, power on again, check the fault status
Emergency stop| Check if the emergency stop button is pressed

Check whether the emergency stop is connected to the corresponding position

Check if the emergency stop is connected to the normally closed contact

Leakage| Check whether the leakage current transformer is connected normally

Check whether the leakage transformer model is the same

Check whether the leakage transformer wiring harness is normal or not 4,Leakage fault during charging needs to be powered off to restore

CP abnormal| Check if the gunwire is connected

Check if CP is recovered after pulling the gun 3,Check ifthere is a loop between CP and PE

Over-current| Check therated power of the EV charger

Check the resistance of load terminal

Overcurrent fault will be clear after pulling out the gun

Over-voltage| Check whether the input voltage is normal

Use a multimeter to check whether the input L-N voltage is normal (three-phase EV charger need to detect Ll \L2\L3 respectively)

overvoltage will be clear after the voltage is restored

Undervoltage| Check if the input voltage is normal

Use a multimeter to check whether the input L-N voltage is normal (three-phase EV charger need to detect L1\L2\L3 respectively)

under voltage will be clear after the voltage is restored

Adhesion| After the power is off, use a multimeter to check whether the input L and output Lare short-circuited or not; check whether the input N and output N are short-circuited or not (three-phase piles need to detect Ll \L2\L3 respectively)

If there is no short circuit, turn on the power again after pulling out the gun, and check whether the adhesion fault is eliminated. If it is not eliminated, it is recommended to perform the third step

If there is a short circuit or the fault is not eliminated, remove the gun wire LN, power on again, and check whether the fault is cleared.

If the fault is still not cleared, please send the control board to supplier for analysis

Before charging,the adhesion fault needs to be powered on again to

clear the fault

Ungrounded| Check whether the input terminal is connected to PE normally

Use a multimeter to check whether the input L-PE and N-PE voltages are normal (three-phase EV Charger needs to be tested for Ll \l2\l3 respectively)

Ungrounded fault during charging ,Pull the gun to clear the fault

---|---
Card reader abnormal| Check if the card reader is connected properly

Check if the status light on the card reader is on

Replace the card reader and power on again

During Charging, The card reader must be offtine and needs to pull out the gun to clear the fault

EEP self-test failed| Check whether components are damaged or missing
