3S-31-PA Pump Control Panel, Highly Flexible, Multi-Function Configurable

3S-31-PA 3 phase simplex pump intelligent control panel - High Flexibility

The panel can be flexibly configured according to different pump types and application requirements, with optional functions and adjustable operating parameters.

Featuring multiple expansion options and a modular structure, the 3 phase simplex pump intelligent control panel allows pump manufacturers to configure on demand, enabling quick adaptation to different pump types and markets.

1. Optional Start-up Modes: DOL, star-delta, soft start, automatic auto-transformer.

2. Optional Pump Power Control Range: 0.37-500kW

Phase type selectable: Can be configured as either single-phase or three-phase controller. Set via parameter P001: 3P = Three Phase, 1P = Single Phase。

3. Configurable Rated Voltage: Single-phase AC110-250V, three-phase AC220-415V

4. Optional Rated Current Setting Modes

U03 Manual Setting: Input the pump's rated current directly.

Self-learning Setting: Start the pump via the panel to run for 20 seconds. The 3 phase simplex pump intelligent control panel will automatically record the average value of three-phase current and save it to U03. When learning is successful, the LCD displays "YES"; if the recorded value is lower than 0.5A, it displays "FAIL", and re-learning is allowed.

5. Optional Modular Expansion for the 3 phase simplex pump intelligent control panel:

Remote Control: RS485, IoT, WiFi

Timed Control: Cyclic Timing, 24-hour Timer

Signal Device: Reserved multiple sets of terminals for easy access

6. Optional Application Modes: Configure for water supply or drainage control according to different scenarios. Set the application mode via parameter U01 on the 3 phase simplex pump intelligent control panel:

1 = Water Supply + Electrode Signal

2 = Water Supply + Float Switch Signal

3 = Water Supply + 2-wire Pressure Switch

4 = Water Supply + 3-wire Electric Contact Pressure Gauge

5 = Water Supply + 2-wire 4-20mA Pressure Sensor

6 = Water Supply + 2-wire 4-20mA Liquid Level Sensor

7 = Water Supply + 3-wire 0-5V Remote Pressure Gauge

8 = Drainage + Electrode Signal

9 = Drainage + Float Switch Signal

10 = Drainage + 2-wire 4-20mA Liquid Level Sensor

11 = Cyclic Timed Start/Stop

7. Optional Control Modes: Manual, Automatic, Timed, Remote Control

1. Enable/Disable Protection Functions: Rust Prevention, Overload, Underload, Overvoltage, Undervoltage, Locked Rotor, Blockage, Signal Loss, Phase Loss (must be disabled for single-phase controllers), Three-phase Unbalance (must be disabled for single-phase controllers)

2. Adjustable Protection Parameters:

Rust Prevention Cycle: 1-999 hours

Automatic Operation Duration of Rust Prevention Pump: 1-999 seconds
