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 3.8
Starter Fault conditon:
1) LMR-A: Manual mode
8A : Check the mode of LMR-A, if it is manual mode.
8B : Switches ON the 3-Phase incoming main supply.
8C : Switch ON the rocker switch
8D : Amber LED will start blinking
8E : Amber LED will blink for a duration of min.30sec.
8F : After the ON delay duration, amber LED remains blinking indicating that the 3phase incoming supply is unhealthy.
8G : - Check the rated operational voltage of the starter in incoming terminal block (TB1) between L1- L2 , L2-L3, L1-L3
1
with suitable equipment e.g. multimeter.
- Check for the phase loss in any phase (L1,L2,L3) with suitable equipment e.g. multimeter.
8H : - After resuming incoming main supply to normal condition,
1
- Repeat the steps from 8A to 8F and then go to step no.8I
If fault still exists, then
8G : - Check the phase sequence of all the phases of incoming main supply.
2
- Identify the wrong sequence of phase connected in any of the incoming terminal.
8H : - Connect the phase sequence of all the phases correctly (R phase to L1 , Y phase to L2, B phase
2
to L3) to the incoming main supply terminals of Terminal block TB1.
- Repeat the steps from 8A to 8F and then go to step no.8I
