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 2.8
1) LMR-A: Manual mode
5A : Check the mode of LMR-A, if it is manual mode, please follow the below steps.
5B : Switches ON the 3-Phase incoming main supply.
5C : Switch ON the rocker switch
5D : Amber LED will start blinking
5E : Amber LED will blink for a duration of min.30sec.
5F : After the ON delay duration, amber LED remains blinking indicating that the 3phase incoming supply is unhealthy.

5G : - 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
5H: - After resuming incoming main supply to normal condition,
- Repeat the steps from 5A to 5E and then go to step no.5I
If fault still exists, then
2
5G : - Check the phase sequence of all the phases of incoming main supply.
- Identify the wrong sequence of phase connected in any of the incoming terminal.
2
5H: - 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 5A to 5E and then go to step no.5I
If fault still exists, then
3
5G : - 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 <minimum required voltage
(Refer table no.13).
3
5H : - Keep the 3-phase voltage to the incoming terminals of terminal block TB1 to a voltage between min.required voltage
& Max.voltage allowed (Refer table no.13).
- Repeat the steps from 5A to 5E and then go to step no.5I
