HOW TO ENTER THE SETTINGS
| Set prefix | Setting description |
| C1 | Pressure calibration setting, the minimum value is 0, the maximum value is 2.0, and the default initial value is 1.0. Correct the current displayed pressure value |
| C2 | The minimum value of water shortage pressure threshold is 0, the maximum value is 1.0, and the default initial value is 0.5. When the water pressure is ower than this value for a long time (the time is set by the water shortage time), the water shortage faulf is reported. |
| C3 | The minimum value of water shortage time is 1, the maximum value is 5, the default initial value is 3, and the unit is minute |
| C4 | Start the pressure proportional setting, the minimum value is 50, the maximum yalue is 90, and the default initial value is 70.When the actual water pressure is lower than(set pressure" starting pressure ratio), the water pump starts automatically |
| C5 | Detect the setting of the high temperature alarm switch of water temperature. 0 is off 1is an |
| C6 | Set the high temperature alarm threshold of water temperature. The minimum value is 25, the maximum value is 80, and the default initial value is 70.When the water temperature is higher than this temperature threshold, the alarm of high water temperature is reported. |
| C7 | Detect the setting of low temperature alarm switch of water temperature.0 is oft.1 is on |
| C8 | Adjust the upper limit of set pressure, maximum 8.0 |
| C9 | Automatic pressure drop detection switch to prevent the water outlet from slowly closing without shutdown due to pressure fluctuation, The default is on, 0 is off, and 1 is on. |
| CA | The smaller the pressure difference is, the less obvious the pressure drop is. However, it may lead to the slow closing of the water outlet without shutdown, and vice versa. The default value is 10, the minimum value is 5. and the maximum value is 20 |
| Cb | The module temperature threshold value is used to adjust the upper limit of power according to the module temperature. The setting range is 0,65~80.0 means to turn off this function. The default value is 65 |
| CC | The main switch of water flow switch, with a range of 0~1, where 0 means closed, 1 means open, and the default is 1. |
| F1~F4 | The motor parameters are not adjustable by the user. |
TROUBLESHOOTING
| Fault display Show code | Fault detection method | Cause of failure |
Troubleshooting |
E01 Voltage too low |
Measure the incoming ine woltage of the frequengy converter |
The incoming line voltage of frequency converter is lower than 140V |
1.Add a voltage regulator to the power supply 2. When the power sugply voltage ecovers to above 150W the fault will be cleared automatically and the water pump will work normally; A regulated power supply is provided for the spedial feed pump; |
| E02 Vollage too high |
Measure the incoming line voltage of the frequency converter |
The incoming line voltage of freguency converter is higher than 260V |
1.Add a voltage regulator to the power supply 2.When the power supply voltage recovers to below 260V the fault will be deaned automaticaly and the water pumo wi work normally; A regulated power supply s provided for the special feed pump: |
E03 Sensor fault |
1.Plug and unplug the sensor signal wire to observe whether the alarm is eliminated; 2.Observe the pressure change of the water ump during emergengy startup operation |
Poor contact between sensor and signal wire |
Turn off the power and plug the signal cable again |
| Abnormal sensor | Replace the sensor | ||
| E04 The controller temperature is too nigh |
Check whether the temperature af the controller heat sink is greater than 90 |
1.The controller temperature is too high 2. The installation position of water pump is not ventilated; Poor contac ot radiator: |
1.Wait for natural cooling 2. Install the water pump at the ventilated place to dissipate heat Check the radiator contact; |
| E08 Motor start failed |
This fault still occurs many times after the fault s cleared automaticaily |
1.The motor cannot be started because the impeller is stuck 2. Startup failed |
1.Take out the water injection component and observe whether there are foreign matters in the pump 2.Contact after-sales service |
| E09 Speed feedback tailed |
This fault still occurs many times after the fault is cleared automaticaily | 1. The impeller is stuck causing the motor to rotate slowly 2. Speed feedback failed |
1. Take out the water injection component and observe whether there are foreign matters in the pump 2.Contact after-sales service |
| E12 High water temperature alarm |
Check whether the water temperature is greater than the set threshold (70 *by default) |
The water temperature is greater than the set threshola |
1.Wait for natural cooling of water temperature; 2.Increase the high temperature threshold of water temperature; Close the high temperature alarm of water emperature |
| Leakage LED Light comes on |
1.With the tap tumed on,The leakage LED lamp | does not tum oft automatically 2. With the tap turned on,The leakage LED light goes out automatically. |
1.The water flow switch is loose or damaged 2.Water pipe leaks |
.Check whether the water flow switch screws are loose,Plug and pull the water flow switch wire Or enter Set CC to close the main switch of water flow switch 2.Contact relevant personnel for handling |
| E21 | On screen display | The panel receives data abnormally | After sales treatment |
| E22 | On screen display | The panel cannot receive data |
Plug and unplug the wire of panel and backplane |
| E11 | On screen display | The backplane canno receive data | Plug and unplug the wire of panel and backplane |
FUNCTION DESCRIPTION
| Function | Remarks |
Water shortag protection |
When there is no water entering the pump or the water pressure is continuously lower than 0.5 (the default value), after running for 3 minutes (the default value), the "water shortage" fault display will appear, and the 'water shortage" light will flash. When the water comes from the pipeline or the water pressure is higher than 0.5 (the default value), press the fault elimination reset start/stop button, and the water pump can work normally again |
| High water temperature protection |
When the water temperature in the water pump is higher than 70°(the default value) for three minutes, a high water temperature alarm will appear. At this time, the "water shortage" light flashes, and the digital tube displays E12 fault. When the water temperature is lower than 65*(ie.5°less than the original 70°), the water pump will automatically resume normal operation. |
Anti Freezing |
When the water temperature in the water pump is lower than 3°and the motor is not working, in order to prevent the water from freezing, the antifreeze protection will be started, and the motor will run at a fixed speed for 5 minutes (if the user uses water at this time, the antifreeze protection will automatically exit). At this time, the "water shortage' light flashes. |
