Fully Automatic Digital Display Water Level Controller with Motor Protection

USER MANUAL

Model No: IT189DWLC
Product: Fully Automatic Digital Water Level Controller with Sensor

 Product Overview

The IT189DWLC is a fully automatic water level controller designed to manage water pump operations based on the water levels in the overhead tank and underground sump. It ensures efficient water management with dry run protection, overload protection, and voltage fluctuation safeguards.

 Package Contents

• 1x Water Level Controller Unit

• 6x Stainless Steel/Carbon Sensors

• 1x User Manual

• Sensor Connecting Wire (Optional, as per model)

Features

• Suitable for single-phase motors (up to 2 HP)

• Works for both overhead & underground tanks

• Auto cut-off when tank is full

• Auto start when tank is low

• Dry run protection

• Overload protection

• Over/under voltage protection

• Digital display for live voltage and current

• Manual & automatic mode operation

• No need to press reset after errors (if timer is set)

Working Description

1. Sensors Configuration

• 6 sensors total

  • 3 for Overhead Tank → G1 (Low), B1 (High), R1 (Common)

  • 3 for Underground Tank → G (Dry Run), B (High), R (Common)

• The common sensors (R & R1) go at the bottom of their respective tanks.

• G/G1 = Low level sensor (Motor ON)

• B/B1 = High level sensor (Motor OFF)

• G Sensor in Sump = Dry run detection

Note: Distance between G and B in sump should not exceed 1 ft.

2. Wiring Instructions

• Power Input: 230V AC (Phase & Neutral) to the input terminals

• Power Output: Connect motor’s phase & neutral to output terminals

• Sensor Wiring: Use 1 mm 3-core cable, ensure sensors are mounted steadily (not floating)

➕ Only Overhead Tank?

If using only overhead tank:

• Short R, G, B sensors of the sump in the panel (link them using a wire)

• G and B LEDs will glow permanently, simulating full sump condition

 Controller Settings

     Auto Setting Mode

• Start motor in manual mode

• Press [SET] button for 3–5 seconds until "SET" appears

• Device auto-detects motor parameters (overload & dry run current)

     Manual Setting Mode

Recommended only if auto setting fails or incorrect

1. Turn off motor

2. Press [SET] once → OC appears

3. Use [UP] / [DOWN] to set OC

4. Press [START] → Next setting: UC

5. Repeat for UC, OV, UV, RST

6. After all settings, wait 3 seconds to auto-exit programming

 Technical Specifications

 Safety Instructions

• Ensure secure sensor mounting (no floating)

• Do not exceed motor capacity

• Use proper grounding and MCB for safety

• Ensure correct polarity while wiring
