If the Platform/Ground Select switch is in the Platform position, it will take approximately 10 seconds for the Control System power to be shut down.
5. If the power shuts down properly, turn the Battery Disconnect Switch back to the On position. Look at the display to verify the power has been turned back on and resume the Function Check. If the power did not shut down or turn on properly, Report the problem to the proper maintenance personnel. Do not operate the machine until it is declared safe for operation.
