Begin Spec B Battery Charge Mode – 50 Hz Only
With the genset running, AC voltage is produced in the B1-B2 windings for the battery charge circuit in the 50 Hz mod-
els only. The 60 Hz Spec B models do not have battery charging.
• The AC output voltage from the B1-B2 winding is converted to DC voltage when it passes through the battery
charger assembly (VR2). The 12-volt DC output (ten-ampere maximum) is used to charge the battery and supply
power to the control assembly (A1) and its outputs.
