BATTERY CHARGING (10) MENU HEADING

Note: See the battery section of this manual for recommended setting for different battery types.

Set Bulk
volts DC	14.4

12 VDC models

Range: 10.0 to 16.0

Set Bulk
volts DC	28.8

24 VDC models

Range: 20.0 to 32.0

Set Bulk
volts DC	57.6

48 VDC models

Range: 40.0 to 64.0

Sets the voltage level that will be maintained during the first and second stage of the charging process. This will be the maximum voltage at which the batteries will be charged. This setting will be

compensated for the battery temperature if the BTS sensor is installed.

Set Absorption

time h:m 02:00

All models

Range: 00:00 to 23:50

Sets the time period that the batteries will be held near the SET BULK VOLTS DC level for the second stage of the battery charging process, this ensures that the battery is well charged. If the automatic generator control system is used, the generator will turn off when the batteries have been held near the SET BULK VOLTS DC setting until the ABSORPTION TIME period has elapsed. This time is an accumulating or up/down type timer - it counts up while the voltage is near the BULK setting and counts back down if the voltage drops. This makes the process more reliable and predictable. If the system designer wants to minimize generator operation, a shorter time may be used. If the system designer wants to ensure that the batteries are fully charged before stopping the charging process, then a longer setting may be used. If the ABSORPTION TIME is set to zero (00:00) the unit will not provide any absorption charge time and go straight to the float charge stage after reaching near the BULK voltage setting.

Set Float
volts DC	13.4

12 VDC models

Range: 10.0 to 16.0

Set Float
volts DC	26.8

24 VDC models

Range: 20.0 to 32.0

Set Float
volts DC	53.6

48 VDC models

Range: 40.0 to 64.0

Sets the voltage level that will be maintained at the final stage of the charging process. This is important for systems which are connected to utility power since the battery charger will often be in this stage most of the time. This setting will be compensated for the battery temperature if the BTS sensor is installed.

Set Equalize
volts DC	14.4

12 VDC models

Range: 10.0 to 16.0

Set Equalize
volts DC	28.8

24 VDC models

Range: 20.0 to 32.0

Set Equalize
volts DC	57.6

48 VDC models

Range: 40.0 to 64.0

Sets the voltage level that the batteries will be limited to during the equalization process. This will be the maximum voltage at which the batteries will be charged. This setting will be compensated for the

battery temperature if the BTS sensor is installed.

Set Equalize
time h:m	02:00

All models

Range: 00:00 to 23:50

Sets the amount of time battery voltage must exceed the BULK VOLTS DC setting before the equalization process is considered to be completed. If the automatic generator control system is used; it will turn off the generator when this timer has reached its setting, and return the cursor from the EQ to the AUTO position. This time is an accumulating or up/down type timer - it counts up while the voltage is above the BULK setting and counts back down if the voltage drops below the BULK setting for a period of time.
