WL Configurator Brief Description

WL Circuit Breaker

WL Configuration software, WL Config©, is a software configuration tool used to set protective settings, set points and additional protective functions in the WL trip unit. It is designed for use on a Windows 2000 or XP PC with a minimum of 128MB RAM and a 1.2GHz or faster processor. The installation is a simple and intuitive process, with step-by- step instructions for the user.

WL Config runs in a web browser window, with the "Main Menu" tree below displayed at start-up:

After the program is installed on the PC, WL Config© communicates with WL Trip Units via the PC’s serial port. The COM16 MODBUS communication module is required for use with this software. An RS485 to RS232 converter is provided as part of the WL Config Software Kit (catalog number: WLCONFIG). WL Config uses the MODBUS protocol to communicate with the COM16 (typically at 19,200 baud, even parity and with a default MODBUS address of 126).

The internal CubicleBUS communications bus of the WL Circuit Breaker allows connectivity between the COM16, Digital I/O, Analog I/O, and Electronic Trip Units (ETU). CubicleBUS requires 24V DC+ power and provides a serial link to all the modules in the WL Circuit Breaker CubicleBUS system. 24V DC power must be available in the system for communication to exist between the PC and the COM16. The serial data generated by the Trip Unit is available at the COM16, which serves as a gateway to the CubicleBUS data.

The main purpose of WL Config is to configure the communication, protective and alarm programmable parameters of the WL Trip Unit, and also configure CubicleBUS Module parameters.

The parameters changed by the user and sent to the device are verified by the PC program and the device for a valid setting, and if out of range, an error message is displayed. Alarms can also be configured for any associated

I/O modules.

WL Config can interrogate a Trip Unit for instantaneous or historical data and display that information for user evaluation. If the system is equipped with the optional Metering Plus module, the voltage and current waveforms and any harmonic information can be viewed.

Note: WL Config can be also used in an offline mode, without a WL Trip Unit attached, to allow the configuration of a particular job to be completed and verified prior to downloading. This offers the advantages of quickly configuring many trip units with the same data and also provides organized electronic files for storing past configurations.
