This product is a motor protection system that safeguards the Single Phase Motor against Overload, Dry Run and Single Phasing. This product also has a built in Cyclic Timer which gives the user an option to periodically run the motor as per the desired time intervals. This product has to be attached to the existing motor starter. It allows the motor load to pass through the CT provided to sense the current . The current drawn by the motor is continuously monitored and displayed on the LCD. The low current and high current settings need to be adjusted by the user. The motor is turned OFF in case of over current, under current (dry run) and when any of the supply phases are absent thus protecting the motor from damages. The reason for the trip along with the tripping current is displayed on the LCD. The device also offers an OFF timer which the user can set to turn OFF the motor automatically after the set time is complete. The sensors are provided additionally which when connected to the overhead tank/underground tank, turns OFF the motor starter when the water fills up.

Maximum Current Range:

1 to 3HP: 30A
1 to 5HP : 50A

Connections:

Connect the incoming power supply lines 220V (Auxiliary supply) to connector 1 and 2 (red and black respectively)
Connect connectors 3 and 4 in parallel to first of the element of the Start Push Button of your motor starter
Connect connectors 5 and 6 in parallel to second of the element of the Start Push Button of your motor starter
Connect connector 7 and 8 in series with the Stop push button of your motor starter
Pass the load wire through the CT provided
Connect the sensor wires to the connectors 9 and 10 (polarity does not matter)

Operation:

The LCD powers up automatically when the supply voltage is given. The device can be programmed into manual or cyclic mode. In manual mode, the motor can be turned ON by pressing the switch on the device. The same switch can be used to turn OFF the motor. In Cyclic mode, you can set the desired running and waiting times. The device switches ON and OFF the motor based on the set timings. While the motor is running, the device safeguards the motor against Overload and Dry Run besides the timing OFF. The sensors are provided as part of the package. If the sensors are connected and placed in the tank, the motor is also turned OFF as soon as the tank fills up.

Technical Specifications:

Wire Size to be used for Connectors 3, 4, 5 and 6 is a minimum of 1.5 sq. mm
The other wire sizes need to be minimum of 0.5 sq mm

Tripping time:

Overload - 12 seconds
Dry Run (Underload) - 8 seconds

Product Dimensions:

Weight: 1180 Grams
Length: 24.1 cms
Breadth: 11.2 cms
Height: 7.7 cms

Setting:

Turn the Overload [H( )] [green knob] to maximum (clockwise)
Turn the Dry Run [L( )] [Blue knob] to minimum (anticlockwise)
Turn ON the motor and observe the load current in the second line of the LCD
Set the Overload H( ) value to 2 points more than the load current by rotating and observing the change in H( ) value in the first line of the LCD.
Set the Dry Run L( ) value to 2 points less than the load current by rotating and observing the change in L( ) value in the first line of the LCD.
Motor OFF Timer is the first knob. If the timer is not required, turn it completely towards the left hand side.
If the OFF timer needs to be set, turn the white knob on the right hand side to increase the time which can be seen on the far right inside the brackets on the second line of the LCD
The numbers appearing next to the current reading outside the brackets are the time elapsed.

Cyclic Timer Settings:

Press set key to enter the timer settings
Observe the cursor blinking in the ON time
Press increase key (on right hand side) to increase the timings (HH:MM:SS)
Press decrease key (on left hand side) to decrease the timings (HH:MM:SS)
After the ON time is set, press Set button
Observe the cursor blinking in the OFF time
Press increase key (on right hand side) to increase the timings (HH:MM:SS)
Press decrease key (on left hand side) to decrease the timings (HH:MM:SS)
Press Set again to save the timings and exit the settings

Power OFF the device
Press and hold the increase and decrease key together
Power ON the device
Release the key as soon as the setting mode prompts
Press increase key to select between Cut Off Mode / Cyclic mode
Press Set button again to save and exit the menu
Note: Set the L( ) value to minimum if the Dry Run Protection is not required.

Application:

Naren DMC-SP is used in all Single Phase Submersible Starters as a protection mechanism to protect the motor against current and voltage irregularities. This device effectively switches OFF the motor in any irregularity and hence prevents burning of the motor windings. The presence of a cyclic timer is a major advantage so that the user can set the running durations. The reason for turning OFF is displayed on the LCD which makes the diagnosis easy. This device is rugged and is specifically designed for agricultural operations. The motor safeguarding devices like these are very critical which will save the users from the costs incurred due to motor failures.
