Relay Passwords; Flexlogic Customization; Commissioning - GE B30 UR Series Instruction Manual

1 GETTING STARTED
The settings for the relay can be programmed manually (see Chapter 5) via the faceplate keypad or remotely via the
EnerVista UR Setup software (see the EnerVista UR Setup help file).
It is recommended that passwords be set for each security level and assigned to specific personnel. There are two user
security access levels, COMMAND and SETTING.
1. COMMAND
The COMMAND access level restricts the user from making any settings changes, but allows the user to perform the fol-
lowing operations:
• Change state of virtual inputs
• Clear event records
• Clear oscillography records
• Operate user-programmable pushbuttons
2. SETTING
The SETTING access level allows the user to make any changes to any of the setting values.
See the Changing Settings section in Chapter 4 for complete instructions on setting security-level passwords.
NOTE
FlexLogic equation editing is required for setting user-defined logic for customizing the relay operations. See the FlexLogic
section in Chapter 5.
The B30 requires minimal maintenance after it is commissioned into service. Since the B30 is a microprocessor-based
relay, its characteristics do not change over time. As such, no further functional tests are required. Expected service life is
20 years for UR devices manufactured June 2014 or later when applied in a controlled indoors environment and electrical
conditions within specification.
The B30 performs a number of continual self-tests and takes the necessary action in case of any major errors (see the
Relay Self-tests section in chapter 7). However, it is recommended that B30 maintenance be scheduled with other system
maintenance. This maintenance can involve in-service, out-of-service, or unscheduled maintenance.
In-service maintenance:
1. Visual verification of the analog values integrity, such as voltage and current (in comparison to other devices on the
corresponding system).
2. Visual verification of active alarms, relay display messages, and LED indications.
3. LED test.
4. Visual inspection for any damage, corrosion, dust, or loose wires.
5. Event recorder file download with further events analysis.
Out-of-service maintenance:
1. Check wiring connections for firmness.
2. Analog values (currents, voltages, RTDs, analog inputs) injection test and metering accuracy verification. Calibrated
test equipment is required.
3. Protection elements setting verification (analog values injection or visual verification of setting file entries against relay
settings schedule).
4. Contact inputs and outputs verification. This test can be conducted by direct change of state forcing or as part of the
system functional testing.
