CHARGING MORE THAN ONE BANK OF BATTERIES
CAUTION! When charging more than one bank of batteries at the same time using
3 Stage Charging, ensure that the batteries in the banks are in a similar discharged
condition. If one bank is completely discharged and another is almost fully charged, the
bank that is fully charged will be subjected to over charge condition during the time
when the charger remains in Stage 2 (“Uo” Phase) for charging the completely
discharged bank.
If 2 banks of batteries are required to be charged and they are at different discharged
conditions, select “Loaded Battery” (2 Stage Charging) with the help of switches
S1 and S2 of theset of 4 DIP Switches (5) (both S1 & S2 in off condition) –
See under “Selecting the Type of Battery and Charging Stages”.
SELECTING THE TYPE OF BATTERY AND CHARGING STAGES
The Float or Maintenance Charge Mode (“U” Phase) voltage and Absorption / Boost
ChargeMode (“Uo” Phase) voltage of different types of Lead Acid Batteries are
different.3 Stage charging (Stages 1, 2 and 3) is recommended when charging
stand alone, unloaded battery (The battery has no load connected to
it when it is being charged).
When the charger is used to charge a battery and simultaneously supply an external load,
the voltage level of Stage 2 is required to be set to the same level as the voltage of Stage 3
to prevent over-charging. Effectively, the battery will be charged in 2 stages only – Stage
1 and Stage 3. This also applies when two banks of batteries are being charged
simultaneously and the batteries in the two banks are in a dissimilar state of discharge.
A pair of switches S1 & S2 out of a set of 4 DIP Switches (5) has been provided for
selecting the battery type and for modifying the Boost Stage when charging loaded
batteries / two banks of batteries with different discharged states. The following
selections can be made with the help of the DIP Switches S1 and S2:
CAUTION! Do not change the DIP Switch setting when the charger is operating.
Always change the DIP Switch setting when the charger is off, i.e. after
disconnecting the charger from the AC input power).
NOTE: The voltages are for battery temperature of 26,7º C
