λλ LMR-A: Bypass mode
a. WLCA- In any 3x mode (Delivery, Suction, Dual Tank)
As in Bypass mode there is no protection from the incoming supply faults, however there may be some conditions,
example mentioned below where Starter may not ON –
1. Phase loss
2. Incoming supply voltage less than the minimum required operational voltage of the Starter.
3. Incoming supply voltage is very high etc.......
Also check the WLC-A faults which may arise due to the sensor misplacement in the tank.Refer 6Note
In the above conditions check the Starters as explained in Auto & Manual Mode.
