3.6 Battery Setup
The Battery menu allows the user to set the low and high battery warning and
failure levels. In addition, the generator can be made to automatically start when
in the AUTO mode if the voltage drops below the Recharge Level.
The controller will display Low Voltage During Cranking on the screen if during
cranking the voltage drops below the Low Vol InCrank setting.
Note: When the generator is running, the battery voltage will equal the alternator
charging voltage. The actual open-circuit battery voltage may be lower than
displayed.
3.6.1 Start on Low Battery
The GSC400 can be setup to automatically run the generator if the battery
voltage goes below the Recharge Level. This feature must be enabled in the
Low Auto Charge submenu.
If the GSC400 is in the AUTO mode and the battery voltage drops and remains
below the Recharge Level for 10s (firmware versions 2.03 and below) or 60s
(firmware versions 2.04 and above) the battery charger action is triggered.
Once activated it is not stopped even if the voltage rises above the Recharge
Level. First the GSC400 goes though a pre-alarm delay displaying a warning
and sounding the buzzer (set by ChargePrealarm), then it starts the generator
and runs for the required time (set by ChargeDuration). Once finished the
GSC400 shuts down the generator and goes back to the AUTO mode.
Note that the GSC400 does not have the capability of charging the battery to a
specified voltage level.
