WL Selection and Application Guide • 2005
WL Circuit Breaker
Transmittable Circuit Breaker Data
Application Options
Transmission of Circuit Breaker Data to MODBUS via COM16 or PROFIBUS via COM15 and
Integration in Higher-level Visualization Systems Possible
e.g. Power Management Systems, such as WinPM.Net, etc.
Transmission of Circuit Breaker Data and Software (i.e. HTML Pages incl. Data)
to a Local Output Device or Remotely Controlled via the Ethernet/Intranet/Internet
(No Integration Option in Higher-level Visualization Systems)
e.g. for monitoring, diagnostics, maintenance and configuration of individual
circuit breakers
Use of the Functionality of all CubicleBUS Modules
e.g. programming of the configurable digital output modules, status interrogation
of digital input modules, diagnostics, testing
Communicated Circuit Breaker Data when No Metering Function is Installed
Device Identification:
Communication address, circuit breaker order no., circuit breaker characteristic data
(Size, no. of poles, rated current module etc.), ID numbers, trip unit type, free text for
equipment identifier and comments
Breaker Status:
Open/closed signal, spring store mechanism, tripped, ready-to-close,
Circuit breaker position (connected, test, disconnected and removed) for drawout
circuit breakers, MODBUS / PROFIBUS write protection on/off, free user input
Control Commands
Open/closed circuit breakers, enable/disable free user output
Reset trip signal
Clear event and trip log
Reset the min/max measured values, reset maintenance information
History
Readout of event log, readout of trip log
Maintenance Information
Number of L, S, I trips and total trips, estimate of contact erosion
Number of switch operations under load and total operations, operating hours
Event Signaling
Trip signal with identification of the current causing the trip
Alarm signaling (e.g. overload) with incoming / outgoing information
All named event signaling with time stamp
Configuration of Protective Functions
Readout of protective function parameters
Change the settings of the protective function parameters through communication
Parameter set changeover option (set A to set B)
Metered Values
Phase currents, each with min/max value
Temperature in the circuit breaker with min/max value
Temperature in the cubicle with min/max value
All named measured values with time stamp
Additional Circuit Breaker Data Transmitted when the Metering Function is Installed
Additional Event Signaling
Setpoint signaling (e.g. over / underfrequency, over / undervoltage)
Configuration of the Extended Protective Functions and Setpoints:
Readout parameters of the extended protective functions
Change the settings of the extended protective functions
Readout and set setpoint values
Additional Metered Values
Voltages, power, energy, power factor, frequency each with min/max value
Harmonic analysis
Recording of currents and voltages by triggered events in the waveform buffer
1 Only possible in connection with the COM16 / COM15 module (MODBUS or PROFIBUS connection
not required).
2 Only possible with ETU755 and ETU776.
Data that can be Transmitted via MODBUS, PROFIBUS or the Breaker Data Adapter (BDA)
