Abstract
The system includes a battery state-of-charge monitoring circuit which is operable to produce a signal change when there is a change in the battery charge from an acceptable charge to a substantially reduced charge. The signal change from the monitor is connected to control a lock-out relay to disable a control circuit for a load controller for battery powered equipment which is to be locked out. A current detecting device is connected to detect the presence of current in the control circuit of the controller and is connected to hold off the lock-out operation of the lock-out relay while current is flowing in the control circuit to thereby assure that the lock-out of the load occurs after a normal interruption of the load control circuit.
