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

Parameter    Description    Example

OC    Overload Current – Set 30–40% above motor current    If motor = 5A → Set OC ~ 7A
UC    Under Current (Dry Run) – Set 20–30% below motor current    If motor = 5A → Set UC ~ 3.5A
OV    Over Voltage Cut-Off    e.g., 280V
UV    Under Voltage Cut-Off    e.g., 170V
RST    Error Reset Time (in minutes)    e.g., 5 mins = Auto-reset after 5 mins

 Setting Procedure (Manual)

    Turn off motor

    Press [SET] once → OC appears

    Use [UP] / [DOWN] to set OC

    Press [START] → Next setting: UC

    Repeat for UC, OV, UV, RST

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