Patent Application
20140028452
Embodiments pertain to a remote annunciator, and more particularly to a remote annunciator that displays a status of electrical connections between a plurality of transfer switches and at least one generator.
Many existing remote annunciators offer support for either a single genset or a single genset and single ATS unit. One of the drawbacks with such systems is that there are typically many gensets that are installed with multiple ATS units. Therefore, multiple remote annunciators are usually required in order to adequately monitor multiple ATS's and gensets. This requirement for multiple remote annunciators adds unwanted cost and complexity to remotely monitoring various electrical systems that include such components.
Some existing remote annunciators are able to annunciate with more than one ATS. However, these types of remote annunciators are unable to annunciate any type of genset status. Therefore, one of the drawbacks is such remote annunciator is that an additional type of remote annunciator is typically required in order to adequately monitor the status of the genset and the multiple ATS's.
The following description and the drawings sufficiently illustrate specific embodiments to enable those skilled in the art to practice them. Other embodiments may incorporate structural, logical, electrical, process, and other changes. Portions and features of some embodiments may be included in, or substituted for, those of other embodiments. Embodiments set forth in the claims encompass all available equivalents of those claims.
In some embodiments, the control 12 recognizes when the plurality of transfer switches 13A, 13B, 13C, 13D and the at least one generator 14 are connected to the control 12.
As shown in
As an example, the control 12 may be connected to the plurality of transfer switches 13A, 13B, 13C, 13D and the at least one generator 14 via a wired ModBus RTU connection. As another example, the control 12 may be connected to the plurality of transfer switches 13A, 13B, 13C, 13D and the at least one generator 14 via a wired ModBus TCP connection. Embodiments are also contemplated where the control 12 broadcasts signals S (see
As shown in
As an example, the control 12 may receive signals from the plurality of transfer switches 13A, 13B, 13C, 13D and the at least one generator 14 to determine a status of the electrical connections that include the plurality of transfer switches 13A, 13B, 13C, 13D and the at least one generator 14. Embodiments are contemplated where the control 12 is connected to the plurality of transfer switches 13A, 13B, 13C, 13D and the at least one generator 14 via a wireless ModBus TCP connection.
As shown in
As shown in
Other embodiments are contemplated where the indicator 20 includes at least one LCD (not shown) that displays a status of the plurality of transfer switches 13A, 13B, 13C, 13D and the at least one generator 14. As an example, the indicator 20 may include at least one LCD that displays a status of the electrical connections that include plurality of transfer switches 13A, 13B, 13C, 13D and the at least one generator 14.
As shown in
Embodiments are contemplated where the remote annunciator includes a selector switch (not shown in FIGS.) that is connected to the control 12. In embodiments that include a selector switch, the control 12 may simulate a power outage at a particular one of the plurality of transfer switches 13A, 13B, 13C, 13D based on the position of the selector switch once the singular test button 25 is activated.
The remote annunciators 10 described herein offer support for multiple ATS units and at least one genset. Therefore, multiple remote annunciators are not required in order to adequately monitor multiple ATS's and gensets. Therefore, the remote annunciators 10 described herein reduce unwanted cost and complexity that are associated with remotely monitoring various electrical systems that include such components.
The Abstract is provided to comply with 37 C.F.R. Section 1.72(b) requiring an abstract that will allow the reader to ascertain the nature and gist of the technical disclosure. It is submitted with the understanding that it will not be used to limit or interpret the scope or meaning of the claims. The following claims are hereby incorporated into the detailed description, with each claim standing on its own as a separate embodiment.
