Fault diagnostics are provided through pretrip data, event record, trace memory,
and statistics. Prior to issuing a trip, the 469 takes a snapshot of the measured
parameters and stores them with the cause of the trip. This pre-trip data may be
viewed using the MENU key, viewing the

A1 STATUS
stores up to 256 time and date stamped events including the pre-trip data. Each
time a trip occurs, the 469 stores a trace of 8 cycles pre-trip and 8 cycles post-trip
for all measured AC quantities. Trip counters record the number of occurrences of
each type of trip. Minimum and maximum values for analog inputs, along with
maximum values for RTDs, are also recorded. These features enable the operator to
pinpoint a problem quickly and with certainty.
Power metering included with the 469 as a standard feature. The table below
outlines the metered parameters available either through the front panel or
communications ports.
The 469 is equipped with 3 fully functional and independent communications ports.
The front panel RS232 port may be used for 469 setpoint programming, local
interrogation or control, and upgrading of 469 firmware. The Computer RS485 port
may be connected to a PLC, DCS, or PC based user interface program. The Auxiliary
RS485 port may be used for redundancy or simultaneous interrogation and/or
control from a second PLC, DCS, or PC software.
There are also four 4 to 20 mA or 0 to 1 mA (as specified with order) transducer
outputs that may be assigned to any measured parameter. The range of these
outputs is scalable. Additional features are outlined below.
METERING:
• Voltage
• Current and amps demand
• Real power, kW demand, kW power consumption
• Apparent power and kVA demand
• Reactive power, kvar demand, kvar consumption/generation
• Frequency
• Power factor
• RTD
• Speed in RPM with a key phasor input
• User-programmable analog inputs.
ADDITIONAL FEATURES:
• Drawout case (for ease of maintenance/testing)
• Reduced voltage starting control for single transition
• Trip coil supervision
• Flash memory for easy firmware updates
All 469 features are standard; there are no options. The phase CT secondaries,
control power, and analog output range must be specified at the time of order. The
469 differential CT inputs are field programmable for CTs with 1 A or 5 A
secondaries. There are two ground CT inputs, one for the GE Multilin 50:0.025 core
balance CT and one for a ground CT with a 1 A or 5 A secondary, also field
programmable. The VT inputs will accommodate VTs in either a delta or wye
configuration. The output relays are always non-failsafe with the exception of the
service relay. The EnerVista 469 Setup software is provided with each unit. A metal
demo case may be ordered for demonstration or testing purposes.
