healthy and will blink if the incoming power supply is unhealthy – Refer 2.8
Starter Fault conditon:
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
1
with suitable equipment e.g. multimeter.
- Check for the phase loss in any phase (L1,L2,L3) with suitable equipment e.g. multimeter.
5H: - After resuming incoming main supply to normal condition,
1
- Repeat the steps from 5A to 5E and then go to step no.5I
If fault still exists, then
5G : - 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.
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
2
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
5G : - Check the rated operational voltage of the starter in incoming terminal block (TB1) between L1-L2, L2-L3, L1-L3 with
3
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).
5H : - Keep the 3-phase voltage to the incoming terminals of terminal block TB1 to a voltage between min.required voltage
3
& Max.voltage allowed (Refer table no.13).
- Repeat the steps from 5A to 5E and then go to step no.5I
