<p>PURPOSE: To supply the power only under the management or a permitted person by setting a first power source activating signal to the non-active state by a power source activating means at the time when a password is not permitted. CONSTITUTION: Only an operator who is permitted to turn on the power source of a remote controller can get the password stored in a large-capacity storage device 56 of the remote controller, and the types his password on a remote control console keyboard. The pass word is sent to a microprocessor 52 through a bus 32 and an adapter 50. If the password is not correct, the operator types his password again; and if the password is not correct still, a line 77 is activated. If the password is correct, the line 77 is checked; and if it is non-active, a line 76 is activated. Thus, the power control system activates a line 60 to turn on the power source of the remote controller.</p> |
