Basler Electric BE1-700 - Manual (Page 36)

7.) Can I make logic settings at the front panel?
No, the front panel cannot program logic settings. Logic settings must be programmed using the
ASCII command interface or BESTCOMS communication software.
8.) Since the BE1-700 is a programmable device, what are the factory defaults?
The factory default preprogrammed logic scheme depends on the specific type of relay ordered.
See Style Chart in Section 1, General Information. A current relay has 700C-5051-A-BE or 700C-
OC79-A-BE (R style) logic. A voltage relay has 700VOUVF-A-BE or 700V-VF79-A-BE (R style)
logic. Default settings are shown with each function in the instruction manual. For input or output
default settings see Section 3, Input and Output Functions. For protection and control functions, see
Section 4, Protection and Control.
9.) Why do I keep getting access conflict errors when I attempt communication with the relay?
If you try to gain access to more than one port at a time, an access conflict results. The relay has
three communication ports: COM 0, COM 1, and COM 2. The front panel HMI and RS-232 port are
considered to be the same port and are designated COM0. COM 1 is the optional rear Ethernet
port. The rear RS-485 port is designated as COM 2. If access at the front panel HMI has been
obtained, access cannot be gained at another port. The front RS-232 port can still be accessed
because the HMI and front RS-232 port are considered to be the same port (COM 0). Access
needs to be gained only when a write command to the BE1-700 is required (control or setting
change or report reset). When access is gained through a port, a five-minute timer starts counting
down to zero. When port activity occurs, the timer resets to five minutes and resumes counting
down. If no activity is seen for the duration of the five-minute timer, access is withdrawn and any
unsaved changes are lost. When activity at a port is no longer required, access should be
terminated with the Exit command. When using BESTCOMS, the Access and Exit commands are
executed for you. Obtaining data or reports from the relay never requires password access.
10.) Why doesn't the Trip LED behave as expected when the relay picks up and trips?
Why don't the targets work properly?
If a protective element is tripping at the desired level, but the targets and fault records aren't
behaving as expected, two commands should be checked. The SG-TARG command needs the
protective element (function) enabled so that targets are logged. The SG-TRIGGER command must
be programmed with the correct pickup logic expression and trip logic expression to initiate fault
records. Section 6, Reporting and Alarm Functions, Fault Reporting, for detailed information about
programming these commands.
Trip LED behavior also depends on the pickup and trip expressions of the SG-TRIGGER command.
When the SG-TRIGGER pickup expression is TRUE and the trip expression is FALSE, the Trip
LED flashes. In other words, a flashing LED means that a protection element is in a picked up state
and is timing toward a trip. When both the pickup and trip expression is TRUE, the Trip LED lights
steadily. The Trip LED also lights steadily when neither expression is TRUE but latched targets
exist. When resetting a target, the Trip LED will not turn off if the fault is still present. The truth table
of Table 2-2 serves as an aid to interpreting Trip LED indications.
