3-Phase Digital Motor Starter + Fully Automatic Water Level Controller (Model No: IT192DWLC)

3-Phase Digital Motor Starter + Water Level Controller

Model: Imagine Technologies 
Model No: IT192DWLC

Power Input: 415V AC, 3-Phase, 50Hz
Control Type: Direct On Line (DOL) Starter with Auto/Manual Water Level Control

1. Product Overview

This device is a fully automatic 3-phase digital motor starter combined with a water level controller. It is designed for submersible or monoblock pumps and provides automatic tank level monitoring, pump control, and motor protection.
Features:

    Automatic ON/OFF operation based on tank water level.

    Manual/Auto selection mode.

    LED voltage and current display.

    Dry run protection.

    Single phasing, low/high voltage, and overload protection.

    Motor ON/OFF push buttons.

    Buzzer alert for fault conditions.

    Supports 5-sensor water level detection.

2. Front Panel Description

Label    Description
Display    Shows Voltage (V) and Current (A)
AUTO / MANUAL Toggle    Toggle between automatic and manual control modes
STOP/RESET    Used to stop the motor manually or reset the device
START    Used to manually start the motor

3. Terminal Details

Input (From Mains)

    R, Y, B – 3-phase power supply input (415V AC)

Output (To Motor)

    A, B, C – Connected to the motor winding terminals

Sensor Input

    B1 – Tank High Level Sensor

    G1 – Tank Low Level Sensor

    R/R1 – Ground Sensor (Need place in bottom )

    G – Dry Run Sensor (Sump Empty)

    B – Sump Full Sensor

4. Sensor Wiring Guide

Connect 5 float or SS rod sensors as follows:
Wire    Sensor Position
B1    Overhead Tank Full Level (Motor OFF)
G1    Overhead Tank Low Level (Motor ON)
R    Reference Voltage Sensor (Ground Sensor)
G    Sump Tank Bottom Sensor (Dry Run)
B    Sump Tank High Sensor (Motor Start Permission)



5. Operating Instructions

Automatic Mode:

    Toggle switch to AUTO.

    Motor turns ON when overhead tank reaches low level (G1) and sump has sufficient water (G present, B not triggered).

    Motor turns OFF when tank is full (B1 activated).

    If G is active (dry run), the system stops motor and retries after delay.

Manual Mode:

    Toggle switch to MANUAL.

    Press START button to run the motor.

    Press STOP/RESET to stop motor anytime.

    Dry run, voltage, and overload protections remain active in both modes.

6. Protections

Protection    Function
Low/High Voltage    Prevents motor start below/above safe voltage limits
Single Phasing    Detects and prevents running on two phases
Overload    Stops motor during overcurrent condition
Dry Run    Stops motor if sump is empty


7. LED Indicators (Typical)

Indicator    Description
ON    Power ON
B1 / G1                Tank level indicators
B / G    Sump water level indicators
Display    Shows voltage (V) and load current (A)


8. Installation Notes

    Always use proper MCB/fuse for protection.

    Ensure phase sequence is correct (R-Y-B).

    Keep sensors clean for long life.

    Use shielded cable for long sensor wires to reduce noise.

9. Troubleshooting

Problem    Solution
Motor not starting in Auto    Check sensor wiring, dry run sensor, voltage level
Motor stops frequently    Check for overload or dry run
No display    Check input power (R-Y-B)
Wrong water level detection    Check for shorted or faulty sensor wires


10. Warranty & Support

    1-year manufacturing warranty.
