Abstract
A method of operating an auto-monitoring circuit of a circuit interrupting device. The method including monitoring one or more signals to determine an operating state of said circuit interrupting device; outputting a first signal having a first voltage level based on the operating state, wherein the first voltage level is greater than zero volts; and outputting a second signal having a second voltage level based on the operating state, wherein the second voltage level is greater than the first voltage level.
Claims18
A method of operating an auto-monitoring circuit of a circuit interrupting device, the method comprising:
- monitoring one or more signals to determine an operating state of said circuit interrupting device;
- outputting a first signal having a first voltage level based on the operating state, wherein the first voltage level is greater than zero volts;
- and
- outputting a second signal having a second voltage level based on the operating state, wherein the second voltage level is greater than the first voltage level.
An auto-monitoring circuit comprising:
- a memory;
- and
- an electronic processor configured to:
- monitor one or more signals to determine an operating state of a circuit interrupting device,
- output a first signal having a first voltage level based on the operating state, wherein the first voltage level is greater than zero volts, and
- output a second signal having a second voltage level based on the operating state, wherein the second voltage level is greater than the first voltage level.
