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
Starter Fault conditon:
1) LMR-A: Manual mode
6A : Motor suddenly stops after running for some time.
6B : Check the mode of LMR-A, if it is Manual mode.
6C : Amber LED will start blinking
6D, 6E : Follow steps from 5G to 5H of manual mode (Refer Table no.12; Corrective action 1)
6F to 6L : Follow steps from 4B to 4I of manual mode (Refer Table no.11)
6M : Motor starts running again.
2) LMR-A: Auto mode
6A : Motor suddenly stops after running for some time.
6B : Check the mode of LMR-A, if it is Auto mode.
6C : Amber LED will start blinking
6D, 6E : Follow steps from 5G to 5H of Auto mode (Refer Table no.12; Corrective action 2)
6F to 6L : Follow steps from 4B to 4I of Auto mode (Refer Table no.11)
6M : Motor starts running again
3) LMR-A: Bypass mode
As in Bypass mode there is no protection from the inconing supply faults, however there may some conditions,
example mentioned below where Starter may not ON –
1. Phase loss
2. Incmoing supply voltage less than the minimum required operational voltage of the Starter.
3. Incoming supply voltage is very high
etc.......
In the above conditions check the Starters as explained in Auto & Manual Mode.
