NA – Starter is unprotected from incoming power supply faults,only protection from load side faults. In this mode, amber LED will
continously ON if incoming power supply is healthy and will blink if the incoming power supply is unhealthy–Refer 1.8
1) LMR-A: Manual mode
2A : Check the mode of LMR-A, if it is manual mode, please follow the below steps.
2B : Switch ON the 3-Phase incoming main supply.
2C : Amber LED will start blinking
2D : Amber LED will blink for a duration of min 30sec.
2E : After the On-delay duration, amber LED remains blinking indicating that the incoming supply is unhealthy.
1
2F : - Check the rated operational voltage of the starter in incoming terminal block (TB1) between L1-L2, L2-L3, L1-L3
with suitable equipment e.g. multimeter.
- Check for the phase loss in any phase (L1,L2,L3) with suitable equipment e.g. multimeter.
1
2G : - After resuming incoming main supply to normal condition, repeat the steps from 2A to 2D and then go to step no.2H
If fault still exists, then
2
2F : - Check the phase sequence of all the phases of incoming main supply at terminal block TB1.
- Identify the wrong sequence of phase connected in any of the incoming terminal.
2
2G : - Connect the phase sequence of all the phases correctly (R phase to L1 , Y phase to L2, B phase to L3) to the incoming
main supply terminals of Terminal block TB1.
- Repeat the steps from 2A to 2D and then go to step no.2H
If fault still exists, then
3
2F : - Check the rated operational voltage of the starter in incoming terminal block (TB1) between L1-L2,
L2-L3, L1-L3 with suitable equipment e.g. multimeter.
- Check whether the 3-phase voltage in the incoming terminals of terminal block TB1 is less than minimum
required voltage (Refer table no.6).
3
2G : - Starter will be operational only if the 3-phase incoming supply voltage is between
min.required voltage & max.voltage allowed (Refer table no.6).
- Repeat the steps from 2A to 2D and then go to step no.2H
