The run-up current of motor (starting current) does not cause relay trip because over current protection of EOCR is not applied during motor run-up time

EOCR-SS Electronic Overload Relay

1. Overload and Phase Loss Protection

2. Independently adjustable starting and Trip Delay

3. Visual Current Setting Aid & Trip Indication(LED)

4. Flexible Power supply (90 to260VAC or 320 to 480VAC )

5. Electronic Shear-pin function

Description

Two of three phase motor currents are monitored by current transformers. External CTs are required for currents more than 60Amps.

The internal soild cicuitry compares with the present current level. When load current exceeds the presets trip lever, red LED illuminates,

and after the present time,the device trips, and change internal SPDT relay contact. Red LED remains illuminated indicating an overload

trip has occurred. Until manual or remote electrical reset by interrupting supply,is initiated. If load current falls off below below set point

before the present delay, device trip timer. With the visual aid of LED, flashing at 100% of present load, actual load currents can be

determined without the aid of Ammeter. TEST button provides the means of testing service-worthiness and integrity of the device.

Intemal relay is energized in normal operation condition(fail-safe ) and will not become relay mode with either supply lost or own failure.

Starting delay time rang:0.2~30 seconds.Trip delay time rang :0.2~10 seconds. May be used as electronic shearpin by setting trip time to

minimum.

How to set up

1) When commission,set start delay time (D-Time knob) to known motor run-up timer,or to the maximum,if not known.

2) Set trip delay time (O-Time knob) to desired trip time.

3) Set load current (LOAD knob) at the rated full load or desired currents.

4) With connection made and control power on, depress TEST button and hold verify the red LED illuminates and the intermal relay

should switch contacts after the sum of D-Time and O-Time. Depress RESET button.

5) Start the motor and notice run-up time. Then ,slowly turn the LOAD knob to the CCW, until the LED flashes, where the 100% of the

actual load currents is indicated. Set the LOAD knob to the desired trip current. 110~125% setting of running current is recommended.

6) Reset D-Time knob setting to normal run-up time.

7) Periodic testing of TEST button is recommended to ensure the full protection as a Preventive Maintenance.
