DS0306 APC Alarm: Battery Voltage 0

The battery voltage of the absolute position detector has dropped to a level at which data can no longer be held. Or, the power was supplied to the pulse coder for the first time. If this problem reoccurs after the power is turned off and then back on, the battery or cable may be defective. Replace the battery with the machine turned ON.

Quick tip:

Replace the battery with the machine turned ON.
