Inputs and Outputs
Programmable Inputs Do Not Operate as Expected
Step 1.
Verify that all wiring is properly connected. Refer to the Typical Connections chapter.
Step 2.
Verify that the inputs are programmed properly.
Step 3.
Verify that the sensing input jumpers are in the correct position. Refer to the Contact Inputs and
Outputs chapter.
Programmable Outputs Do Not Operate as Expected
Step 1.
Verify that all wiring is properly connected. Refer to the Typical Connections chapter.
Step 2.
Verify that the outputs are programmed properly.
Step 3.
Verify that the output is not being set by other means. There can be more than one connection
to an output (check the physical outputs tab in BESTlogicPlus). Also, check that the output
override is not set for the output.
Metering/Display
Incorrect Display of Current
Step 1.
Verify that all wiring is properly connected. Refer to the Typical Connections chapter.
Step 2.
Verify that the proper current is present at BE1-11g current sensing inputs IA1 (D1/D2), IB1
(D3/D4), IC1 (D5/D6), and IG1 (D7/D8). If two sets of CTs are present, also verify proper
current at IA2 (F1/F2), IB2 (F3/F4), IC2 (F5/F6), and IG2 (F7/F8).
Step 3.
Verify that the current transformer ratio and sensing configuration is correct.
Step 4.
Verify that the current sensing transformers are correct and properly installed.
Incorrect Display of Voltage
Step 1.
Verify that all wiring is properly connected. Refer to the Typical Connections chapter.
Step 2.
Verify that the proper voltage is present at BE1-11g voltage sensing inputs VA (C13), VB (C14),
VC (C15), and VN (C16).
Step 3.
Verify that the voltage transformer ratio and sensing configuration is correct.
Step 4.
Verify that the voltage sensing transformers are correct and properly installed.
General Operation
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.
Why won't the 60FL alarm or target reset when I press the Reset key on the front panel?
The only way to reset the Fuse Loss alarm or target is to apply more than 85% of rated positive-sequence
voltage. Refer to the Fuse Loss (60FL) chapter for more information.
Do I have to log in to reset the targets or alarms?
It depends on the security setup. You can reset the targets or alarms through a specific port without
logging in if the Unsecured Access Level is set to Operator or higher on that port. Target and alarm reset
can also be set outside of security control, allowing reset through the front-panel interface without logging
in. Refer to the Security chapter for more information.
