Control circuit for automatic deactivation of energy reducing maintenance switch

A method for operating an Energy Reducing Maintenance Switch (ERMS), the method comprising:

• charging a coil of the ERMS by closing a first switch of the ERMS, wherein the first switch is normally open;
• closing a first normally-open contact of the ERMS and energizing the ERMS by charging the coil;
• starting a delay timer of the ERMS, to count from a first present time to a second preset time, when the first normally-open contact is closed;
• closing a second normally-open contact of the ERMS upon starting the delay timer to count;
• activating instantaneous settings of a relay of the ERMS, by activating an input signal to the relay, upon closing the second normally-open contact;
• and
• while the delay timer counts from the first preset time to the second preset time, keeping the second normally-open contact of the ERMS closed.

A non-transitory computer readable medium (CRM) storing instructions for performing an operation on an Energy Reducing Maintenance Switch (ERMS), the operation comprising:

• charging a coil of the ERMS by closing a first switch of the ERMS, wherein the first switch is normally open;
• closing a first normally-open contact of the ERMS and energizing the ERMS by charging the coil;
• starting a delay timer of the ERMS, to count from a first present time to a second preset time, when the first normally-open contact is closed;
• activating the instantaneous settings of a relay of the ERMS, by activating an input signal to the relay, when the delay timer starts to count;
• closing a second normally-open contact of the ERMS upon starting the delay timer to count;
• and
• while the delay timer counts from the first preset time to the second preset time, keeping the second normally-open contact of the ERMS closed.
