The GE Multilin 469-P5-HI-A20-T is part of the 469 Motor Management Relay family produced by GE Digital Energy. It is a 5A Phase secondary 90-300VDC 70-265VAC with an enhanced display. Additionally, it incorporates an ethernet port on the back of the relay. The “T in the part number 469-P5-HI-A20-T indicates the addition of the optional ethernet enhancement. A SR469 case with a cut-out in the back must be used to allow access to the port. While no harsh environment conformal coating is present with this model, adding a “H” to the part number in the order code would indicate conformal coating.
Information regarding how to configure a relay with ethernet communication can be found in the “Configuring Ethernet Communications” section of the GE Multilin 469 Manual part number 1601-0122-A9. The EnerVista 469 setup software must be used to configure the 469-P5-HI-A20-T properly. The EnerVista 469 software may come preloaded on a CD with the relay purchase, or it can be easily downloaded from General Electric’s online resources. EnerVista 469 can be used to configure setpoints and export system data for later analysis.
Frequently Asked Questions about 469-P5-HI-A20-T
What does enabling the settings do for the Relay 469-P5-HI-A20-T?
When the settings are enabled on the interface of the relay 469-P5-HI-A20-T it doesn’t immediately enable the access to the other interfaces. A pass code has to be specificly set beforehand on the relay to access the interface that is needed. When all changes are made demand can be made to disable the access to the settings.
Are there security features for a SCADA program that is on my GE 469-P5-HI-A20-T Relay?
Yes, this Relay 469-P5-HI-A20-T can be programmed with a security application using a SCADA system, but it is the programmer’s responsibility to assimilate the correct security for this relay and application.
What features are designated for the motor management applications of the 469-P5-HI-A20-T?
The features for the 469-P5-HI-A20-T motor management relay has a lot of features that are designated to help with a wide range of applications. Making settings for this multi functioning device can be difficult, but if you gather enough systems data like CT primary and secondary ratings, motor names for data, motor operating curves, VT primary ratings and more. You should define the elements that will be protecting the relay when it is enabled. Also making a list of functions that will protect the directionality, time delays, opertaing curves, any time dial and multiplier, or pickup parameter.
