Basler Electric GENERATOR PROTECTION SYSTEM BE1-GPS100

Each independent function block has all of the inputs and outputs that the discrete component counterpart might have. 

Programming with BESTlogic is equivalent to choosing the devices required by your protection and control scheme and then drawing schematic diagrams to connect the inputs and outputs to obtain the desired operating logic. Several preprogrammed logic schemes and a set of custom logic settings are provided.

 A preprogrammed scheme can be activated by merely selecting it.

 Custom logic settings allow you to tailor the relay functionality to match the needs of your operation's practices and power system requirements. 

Write Access Security Security can be defined for three distinct functional access areas: Settings, Reports, and Control.

 Each access area can be assigned its own password. A global password provides access to all three functional areas. Each of the four passwords can be unique or multiple access areas can share the same password.

 A second dimension of security is provided by allowing the user to restrict access for any of the access areas to only specific communication ports. 

For example, you could set up security to deny access to control commands from the rear RS-232 port that is connected through a modem to a telephone line. Security settings only affect write access. Read access is always available in any area through any port. 

Human-Machine Interface (HMI) Each BE1-GPS100 comes with a front panel display with five LED indicators for Power Supply Status, Relay Trouble Alarm, Minor Alarm, Major Alarm, and Trip. The lighted, liquid crystal display (LCD) allows the relay to replace local indication and control functions such as panel metering, alarm annunciation, and control switches. Four scrolling pushbuttons on the front panel provide a means to navigate through the menu tree. 

Edit and Reset pushbuttons provide access to change parameters and reset targets, alarms and other registers. In Edit mode, the scrolling pushbuttons provide data entry selections.

 Edit mode is indicated by an LED on the Edit pushbutton. The LCD has automatic priority logic to govern what is being displayed on the screen so that when an operator approaches, the information of most interest is automatically displayed without having to navigate the menu structure. 

The order of priorities is: 1. Targets 2. Alarms 3. Programmable automatic scrolling list Up to 16 screens can be defined in the programmable, automatic scroll list.

 Communication Three independent, isolated communication ports provide access to all functions in the relay. COM 0 is a 9-pin RS-232 port located on the front of the case. 

COM 1 is a 9-pin RS-232 port located on the back of the case. COM 2 is a two wire RS-485 port located on the back of the case.

 An ASCII command interface allows easy interaction with the relay, using standard, off the shelf communication software. 

The ASCII command interface is optimized to allow automation of the relay setting process.

 Settings files can be captured from the relay and edited using any software that supports the *.txt file format.

 These ASCII text files can then be used to set the relay using the send text file function of your communication software.
