Basic Function Features

Basic Function Features

Operation Command Route

4 Routes: 1. Keypad control; 2. Digital input terminal control; 3. Communication control; 4. Water inlet pressure control

Built-in Clock

Built-in RTC for LCD keypad series

PID Built-in PID

Advanced PID calculation, convenient to realize close-loop control

Host-auxiliary online system

Can be extended to dual RS 485 communication; A driver can be set as the host in the system to control the work of other auxiliary drivers by communication (up to 5 auxiliary drivers). The host sends PID feedback to the auxiliary drivers and detects the state of them in real time. If there is an error, it will automatically skip this auxiliary driver, you can set a backup host. The host can communicate with the upper machine at the same time without being affected; The auxiliary drivers can also communicate with other devices at the same time.

AVR Function

Can automatically keep the output voltage stable when grid voltage fluctuates; This function is invalid when gird voltage decreases as factory setting.

Stall Control

Automatically limit output current and voltage during running, to prevent frequent overcurrent and overvoltage trips

User Password Setting

A 4-digit password can be set, which is a non-zero number; after setting, exit the password setting interface, it will take effect after 1 minute

Parameter Lockup Function

Define whether the parameters are locked under running or stop state to prevent misoperation

Pump Control Functions

Automatic Energy Saving Running

Automatically lower output voltage at light load to achieve energy saving

Automatically Startup when Powered on

Optional: automatically startup when powered on, or startup delay

Antifreeze Function

Antifreeze operation selection, frequency, time, period

Water Leak Detection

Optimizing dormancy control by water leakage detection coefficient

Water Supply Protection

High Pressure Warning

Detect the feedback pressure and protect the pipe network

Low Pressure Warning

Detect the feedback pressure and protect the pipe network & pump

Dry Run Protection

There are a variety of dry run protection detection methods (including sensorless methods). When the driver detects that the water pressure of the pipe network is lower than the dry run pressure, the system automatically stops working, and after a set time, it automatically restarts a specified number of times, if water pressure recovers to normal, the system enters the normal working state, otherwise, the system automatically shuts down to prevent the pump from idling in the absence of water, and extend the service life of the pump to the greatest extent.
