Battery Low Voltage Warning Indicators
The Platform Control Console and Ground Control Station indicate battery low voltage at three (3) Warning Levels.
IMPORTANT: The 3 Levels of Battery Low Voltage Warning indication will only activate on Ground Control Modules with version 29 or later Ground
Control Module software (implemented 8/2004). However, machines with earlier versions of software must follow the same LED/BAR indicator
guidelines and battery charging cycles to maximize battery life.

NOTE: (a) To maximize battery life, it is recommended that the factory supplied batteries be charged continuously for a minimum of 4 hours or
until 8 bars are lit on the ground station LCD Display before operating the machine. When drained to Warning Level 2 or 3, batteries
must be charged until 8 bars are lit on the ground station LCD display to clear the fault code.
To Charge Batteries
1. Park machine in a well ventilated area near an AC volt-
age electrical outlet.
2. Check the AC voltage selector switch on front of the
battery charger is set to correct local AC voltage.
NOTE: The batteries on DVL/DVSP machines require
approximately five (5) hours to fully charge when
drained to LOW BATTERY VOLTAGE warning on
the Ground Control Module LCD display.
