Quick Start
2-7
As you gain knowledge of the relay, you can experiment with the rest of the settings. To set up a file with
all user settings, enter S and the relay will respond with all settings in command format. You can also record
your settings in the
Relay Setting Record (Appendix C). A Microsoft® Excel spreadsheet of the Relay
Settings Record is available for creating and documenting your relay settings. This file may be downloaded
from Basler Electric’s Web site (http://www.basler.com) or by contacting Basler Electric, Info/Support Section
at the Highland, Illinois facility. You may also use the GUI as discussed previously in this section.
Default settings can be found several different ways. The default preprogrammed logic scheme is
BASIC-OC. Section 8,
Application, lists all of the default logic settings for the default logic scheme. If you
wanted to know the default logic setting for relay output 3 (VO3), you could look at the default listing and find
that SL-VO3=51PT. Translated, this means that the setting, logic–virtual output 3is TRUE (1) when the
phase time-overcurrent element trips. You could also look in Section 4,
Protection and Control, find the table
for the logic settings, and it lists the same information, but lists the mode and block inputs separately. If you
want to find the default settings for an input or output, look in Section 3,
Input and Output Functions.
Checking The State Of Inputs
You can review the state of the inputs through the front panel HMI, or the ASCII command interface. The
front panel HMI displays the input status on screen 1.4.1. A diagram showing all of the menu tree branches
is located in Section 10,
Human-Machine Interface. To get to this screen, press the up scrolling pushbutton
until you reach the top screen in the current branch. You know when you have reached the top screen
because the screen stops changing when you press the up scrolling pushbutton. From this position, press
the right scrolling pushbutton until you have reached the screen titled, REPORT STATUS. From this position
press the down scrolling pushbutton one time (TARGETS) and press the right scrolling pushbutton three
times. At this time, you should see the OPERATIONAL STATUS screen. If you press the down scrolling
pushbutton from this screen, you should see the INPUTS screen (IN 1234).
To check the state of the inputs using the ASCII command interface; Type in the RG-STAT command and
press enter. This command only reads the status of the inputs.
Testing
To determine if the relay is responding correctly to each test, the following commands are useful.
1.
RG-TARG, (report general targets): reports the targets from the last fault.
2.
RF, (report faults): reports a directory listing of the twelve fault summary reports. The fault summary
reports are numbered from 1 to 255 and then wrap around and start over. RF-### reports the ###
report.
3.
RS-##, (report sequence of events record), ## events: reports the most recent ## changes of state
in the protection and control logic.
FAQ/TROUBLE SHOOTING
Frequently Asked Questions
1.
Why won't the trip LED reset when I press the reset key on the front panel?
The Reset key is context sensitive. To reset the trip LED or the targets, the target screen must be
displayed. To reset the alarms, the alarm screen must be displayed.
2.
Is the power supply polarity sensitive?
No, the power supply will accept either an ac or dc voltage input. However, the contact sensing for the
programmable inputs is polarity sensitive. Refer to Section 12,
Installation, for typical interconnection
diagrams.
3.
What voltage level is used to develop current flow through the contact sensing inputs?
Voltage level is dependent on the power supply option (called out in the BE1-951 style chart). See
Section 12,
Installation, for additional information.
