Basler Electric BE1-700 - Manual (Page 35)

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, 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/TROUBLESHOOTING
Frequently Asked Questions (FAQs)
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 Targets screen must
be displayed. To reset the alarms, the Alarms 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 BE1-700 style chart). For
additional information, see Figure 1-1 in Section 1, General Information, and Section 12,
Installation.
4.) Does the BE1-700 trip output contact latch after a fault?
The answer to the question is yes and no. In general, once the fault goes away the output contacts
open. The BE1-700 does offer an option to ensure that the contact will stay closed for at least 200
milliseconds. See Section 3, Input and Output Functions, for additional information on that function.
But, BESTlogic can keep the relay outputs closed as long as power is applied. Refer to Section 8,
Application, Application Tips, for additional information.
5.) Why won't a function work when I put in settings such as the pickup and time delays?
Make sure that the logic for the function is set to "Enable".
6.) How many overcurrent elements does the BE1-700 have available?
The BE1-700 has six instantaneous overcurrent and four time overcurrent elements. Just like any
element each of these elements can be assigned to any output for building logic equations.
