13-6 BE1-951 Testing and Maintenance 9328900990 Rev L
During this brief test, all front panel LEDs flash momentarily, the display indicates each step of the self-
test, the relay model, the software version, and then the default display screen. Contact Basler Electric,
Technical Support Services if anything appears out of the ordinary or if an LCD error message appears.
Communications
Purpose: To verify that the BE1-951 relay communicates through all ports.
Reference Commands: ACCESS, EXIT
To communicate with the BE1-951 through any of the three ports, use a terminal emulation program such
as HyperTerminal or VT-100 terminal running on a personal computer (PC) with a serial port that is
suitable for communications. The relay communication default settings are:
• Baud rate = 9,600 bps
• Data bits = 8
• Stop bit = 1
• Parity = None
• Flow Control = Xon/Xoff
Set up the Relay to Communicate with the PC
Step 1: Depress the Up arrow pushbutton on the front panel HMI until the top level of the menu tree is
reached. Depress the Left/Right arrow pushbuttons until Screen 6, General Settings appears.
Next, depress the Down arrow pushbutton twice to get to Screen 6.1.1, COM0 F-232. This
screen displays the baud rate for the front panel communication port (COM0). Verify that the
baud rate is 9,600 bps.
Step 2: Connect the serial cable between the PC and the front RS-232 port on the relay.
Step 3: Initiate the communication program for your computer.
Step 4: Transmit the command ACCESS=. (You may use the shortcut keystrokes and just enter a=.)
RESULT: The relay should respond with ACCESS GRANTED: GLOBAL.
Step 5: Transmit EXIT.
Step 6: Repeat Steps 1, 2, and 3 for the rear RS-232 port (COM1).
Step 7: Connect the male end of the terminal cable to the RS-232 port on a RS-232/485 converter box.
Connect the RS-485 output of the converter box to the relay RS-485 terminals and repeat Steps
1, 2, and 3.
Style Number and Serial Number Verification
Purpose: To verify that the BE1-951 relay model number, style number, and current software program
version matches the unit and unit labels.
Reference Commands: RG-VER
Step 1: Through any communications port, transmit the command RG-VER. The BE1-951 relay should
respond with the model number, style number, application program version and date, boot
program version and date, and the relay serial number. Verify that all reported data is current,
appropriate and matches the label on the relay front panel.
IRIG Verification (If used)
Purpose: To verify that the BE1-951 relay acquires and updates IRIG time and date information.
Reference Commands: RG-DATE, RG-TIME
Step 1: Connect a suitable IRIG source to relay terminals A1 and A2.
Step 2: Upon receiving the IRIG signal, the relay clock will be updated with the current time, day, and
month. Verify this at Screen 4.6 on the front panel HMI or by sending the RG-TIME and RG-
DATE commands to the relay through any communications port.
Contact Sensing Inputs
Purpose: To verify that the BE1-951 relay senses hardware input and output status.
Reference Commands: ACCESS, CO-OUT, CS-OUT, EXIT, RG-STAT
