PREPARED BY: CHECKED BY: APPROVED BY: -----------------------------------------------------------------------------------------SYSTEM CONFIGURATION CONFIGURATION The Total DC system consists of 2 no’s identical Float cum Boost Chargers Type 48 TP 75 FCBC associated with 2 battery banks. Both the chargers have 3 phase Full wave full controlled bridge modules. On the AC side, each charger is fed from separate 3phase, 4 wire per unit the 400V, 50Hz supply. Input ON/OFF Switch+Fuse+Contactor+TOV Switch+Fuse+Contac tor+TOV is provided at the input side of the each charger. A input voltmeter is provided in each charger to read i/p voltage. On the DC side, charger ON/OFF MCCB,BTY side Fuses & blocking diode is provided. Output voltmeters and output ammeters are provided to read charger output voltage &

For Boost charging Battery-1 with Charger-1 K3 is Off, K7 is in ON For Boost charging Battery-2 with Charger-2 K5 is Off, K7 is in ON Interlock is provided, such that charger will not operate in boost mode unless above condition is met. Note: The charger will changeover to boost mode depending on battery trickle charging current. In this scheme of two chargers & two batteries, one charger will changeover automatically to boost mode. Another battery charger will not changeover to boost mode i.e. It will remain in float mode & will supply the DC load as well as trickle charge the respective battery. Interlock is provided such that only one charger will changeover to boost mode. After completion of boost charging of one battery set, the another battery charger will changeover to boost mode automatically only if trickle charging current is remains above the set value of it for auto changeover. Alternatively another battery set has to be boost charged manually. Position-2 (Manual): In Manual mode, charger will start in float mode & will supply the DC load as well as trickle charger the respective battery. If Battery requires Boost charging, operate the charger in boost mode through float/boost selector switches.
For this manual change over from float mode to boost mode, the positions of K3, K5 & K7 shall be as follows.

UPON RESUMPTION OF AC MAINS POWER
Upon resumption of AC mains power the chargers develop float voltages and resume normal operation of supplying load and float charging the batteries. However the batteries may have been discharged and needs boost charging. Their respective charger will monitor the battery current and the batteries will be boost charged one after the other. When one charger is under boost charging its associated battery, other charger and battery will be kept under float charging condition only. On completion of boost charging of first battery bank the second bank can be boost charged. Boost charging is o ffline by opening the load contactor. In this condition Tie breaker contactor (k7) in ON condition in any one of the contactor in OFF position (Due to boost charging the battery) INCASE ONE OF THE CHARGER FAILURE UNDER NORMAL CONDITION:
In the above condition the healthy charger supplies the load while floating associated battery. In this condition Tie-breaker contactor (K7) will be in ON position. INCASE OF BOTH THE CHARGERS FAILURE
In case of both charges failure under normal conditions both batteries start supplying the load through contactors K3 and K5. Tie-break contactor (K7) is also in ON in this
