CHAPTER 5: SETTINGS
Banks are ordered sequentially from the block of lower-numbered channels to the block of higher-numbered channels,
and from the CT/VT module with the lowest slot position letter to the module with the highest slot position letter, as follows.
Increasing slot position letter -->
CT/VT module 1 CT/VT module 2
< bank 1 > < bank 3 >
< bank 2 > < bank 4 >
The UR platform allows for a maximum of six sets of three-phase voltages and six sets of three-phase currents. The result
of these restrictions leads to the maximum number of CT/VT modules in a chassis to three. The maximum number of
sources is six. A summary of CT/VT module configurations is as follows.

5.2.2.3 CT/VT input channel configuration
Upon relay startup, configuration settings for every bank of current or voltage input channels in the relay are generated
automatically from the order code. Within each bank, a channel identification label is assigned automatically to each bank
of channels in a given product. The bank naming convention is based on the physical location of the channels, required by
the user to know how to connect the relay to external circuits. Bank identification consists of the letter designation of the
slot in which the CT/VT module is mounted as the first character, followed by numbers indicating the channel, either 1 or 5.
See the HardFiber instruction manual for designations of HardFiber voltage and current banks.
For three-phase channel sets, the number of the lowest numbered channel identifies the set. For example, F1 represents
the three-phase channel set of F1/F2/F3, where F is the slot letter and 1 is the first channel of the three channels.
Upon startup, the CPU configures the settings required to characterize the current and voltage inputs, and it displays them
in the appropriate section in the sequence of the banks (as described earlier) as follows for a maximum configuration: F1,
F5, M1, M5, U1, and U5.

5.3.1 Security

5.3.1.1 Security overview
The following security features are available:
• Password security — Basic security present by default
• EnerVista security — Role-based access to various EnerVista software screens and configuration elements. The
feature is present by default in the EnerVista software.
• CyberSentry security — Advanced security available using a software option. When purchased, the option is
automatically enabled, and the default Password security and EnerVista security are disabled.
Lost password
If all passwords are lost, recovery is possible by resetting the unit to default values. Note that the relay is reset to default
values, not just the passwords.
To reset the unit after a lost password:
1. Email GE customer service at multilin.tech@ge.com with the serial number and using a recognizable corporate email
account. Customer service provides a code to reset the relay to the factory defaults.
2. Enter the reset code on the front panel, under
