Basler Electric BE1-CDS240 General Information - Manual (Page 6)

Fuse Loss Protection
• A fuse loss function, 60FL, protects against false tripping due to a loss of voltage sensing.
Breaker Failure Protection
• Four (4) breaker failure protection function blocks are assignable to any of the current input
circuits: 50BF, 150BF, 250BF, and 350BF.
• The current circuit assigned to the breaker failure function block also determines which current
circuit is used by the breaker monitoring functions described later.
General Purpose Logic Timers
• Four (4) general-purpose logic timers with six modes of operation: 62, 162, 262, and 362.
Virtual Control Switches
• Four (4) virtual breaker control switch, accessible locally from the HMI or remotely from the
communications ports can be used to provide trip and close control of a selected breaker: 101,
101A, 101B, and 101C.
• The breaker label provided for the breaker monitoring function is used to label the virtual breaker
control switch. This makes it easily discernible which breaker is being controlled as up to four (4)
breakers can be controlled.
• Eight virtual switches with three modes of operation, accessible locally from the HMI or remotely
from the communications ports. Switches can be used to provide additional control: for example,
to trip and close additional switches or breakers, or to enable and disable certain functions: 43,
143, 243, 343, 443, 543, 643, and 743.
Metering Functions
• Metering, including magnitude and angle, is provided for all measured phase and neutral voltage
and currents and all derived positive, neutral, and negative-sequence voltage and currents.
Power factor, frequency, watts, vars, and demands are also provided.
• Metering, including magnitude and angle, is also provided for the phase and tap compensated
restraint, second and fifth harmonic, and differential currents.
Reporting and Alarm Functions
Relay Identification
• The relay includes four 30-character, free-form fields for the user to enter information to identify
the relay. Examples would be station name, circuit number, relay system, purchase order, etc.
These fields are used by many of the reporting functions to identify which relay created the report.
Clock
• A real-time clock is included with a capacitor backup that will keep time upon loss of power for 8
to 24 hours depending upon conditions. Optional battery backup maintains time keeping for an
extended period.
• A standard IRIG input (format B002 from IRIG Standard 200-98) is provided for receiving time
synchronism signals from a master clock.
• The time and date reporting format is settable for 12 or 24-hour format and for mm/dd/yy or
dd/mm/yy format.
• Automatic daylight savings time adjustment can be enabled.
• Recording of time or date changes made via Modbus or DNP to the sequence of events can be
enabled.
General Status Reporting
• The relay has extensive capability to report its general status for monitoring, commissioning, and
troubleshooting.
• Status reports are available from the HMI or the communications ports.
Demand Reporting
• Ampere demand registers are provided for monitoring A, B, C, N, and Q. These registers are
assignable to any of the current input circuits.
