Electrical panel access and control apparatus including true emergency stop and power buss lockout

A power disconnect controller for an electrical access panel including a power buss, the controller comprising:

• one or more electrical switches operative to interrupt and reinstate power along the power buss;
• a user interface including capability for entry of an access code, and a status monitor;
• and
• wherein the user interface is in electrical communication with the one or more electrical switches to implement one or more functions in conjunction with the entry of the access code by one or more authorized users wherein the one or more functions include;
• a LOCKOUT function, whereby power is interrupted along the power buss, and a RESET function, whereby power is reinstated along the power buss;
• the electrical access panel includes one or more doors with door sensors;
• and
• the unauthorized opening of one or more of the doors causes the one or more electrical switches to interrupt power along the buss;
• wherein the user interface further includes a BYPASS function allowing power to be on along the buss when one or more of the doors are open.

A power disconnect controller for an electrical panel including a power buss, an access door and an emergency stop interface to one or more emergency stop buttons, the controller comprising:

• one or more electrical switches operative to interrupt and reinstate power along the buss;
• a user interface including capability for entry of an access code, and a status monitor;
• and
• wherein the controller is operative to implement the following functions:
• a LOCKOUT function, whereby power is interrupted along the buss in conjunction with the entry of the access code by one or more authorized users,
• a RESET function, whereby power is reinstated along the buss in conjunction with the entry of the access code by all of the one or more authorized users that have entered the LOCKOUT function,
• an emergency stop function configured to cause the one or more electrical switches to interrupt power along the buss upon loss of a signal from an emergency stop button, and
• an access door open function configured to cause the one or more electrical switches to interrupt power along the buss upon sensing an unauthorized opening of the access door.

A power disconnect controller for an electrical panel including a power buss, an access door and an emergency stop interface to one or more emergency stop buttons, the controller comprising:

• one or more electrical switches operative to interrupt and reinstate power along the buss;
• a user interface including capability for entry of an access code, and a status monitor;
• and
• wherein the controller is operative to implement the following functions:
• a) a LOCKOUT function, whereby power is interrupted along the buss in conjunction with the entry of the access code by one or more authorized users,
• b) a RESET function, whereby power is reinstated in conjunction with the entry of the access code by all of the one or more authorized users that have exited the LOCKOUT function,
• c) an emergency stop function configured to cause the one or more electrical switches to interrupt power along the buss upon receipt of a signal from an emergency stop button,
• d) an access door open function configured to cause the one or more electrical switches to interrupt power along the buss upon sensing an unauthorized opening of the access door,
• e) a BYPASS function that allows power to be on along the buss when the access door is open, and
• f) display, on the status monitor:
• each of the one or more authorized users implementing the LOCKOUT and RESET functions,
• the occurrence of an emergency stop condition, and
• the unauthorized opening of the access door.
