Commissioning Testing
Special precautions should be taken to ensure that all tests are performed with safety as the greatest
concern. Any CT circuit signals routed through this device as part of a protection scheme, including
discrete relays or as a stand-alone device, should be shorted and isolated from this BE1-11t during these
tests.
If this BE1-11t is being installed in an existing installation, be aware of the equipment monitoring features
of this device, especially if the monitoring logic will be utilized. Make note of any pretest operation levels,
duty levels, etc. on existing equipment (e.g., breakers or transformers). As the user, you can make the
determination of what values the BE1-11t should have as initial monitoring values when the BE1-11t is
placed in service.
It may on occasion be necessary to temporarily disable some of the protective elements while testing the
BE1-11t to isolate testing of individual functions. Always remember to enable these functions before
placing the BE1-11t in service.
To assist you in the commissioning testing of this BE1-11t, you can refer to the related reporting and
alarms chapters.
Please refer to the related protection and control chapters of the instruction manual for assistance on any
particular functions of the BE1-11t. If you require further assistance, contact Basler Electric field
application personnel or the factory.
Digital I/O Connection Verification
Contact Sensing Inputs
Purpose: To verify operation, labels, and logic settings of the contact sensing inputs.
Chapter Reference: Contact Inputs and Outputs
Step 1: Use the Settings Explorer in BESTCOMSPlus
® to open the Programmable Inputs, Contact
Inputs screen and verify the Input 1 through Input 7 user-defined name, recognition time,
debounce time, energized state label, and de-energized state label.
Step 2: Use the Metering Explorer in BESTCOMSPlus to open the Status, Inputs screen. Verify the
status of Input 1. From the actual field device, energize (or de-energize) the specific contact that
supplies BE1-11t Input 1. While maintaining contact position, verify that Input 1 has changed
state on the Status, Inputs screen of BESTCOMSPlus or the front-panel display. Return the field
contact to its original state, verifying that Input 1 returns to its original state. Use the Metering
Explorer in BESTCOMSPlus to open the Reports, Sequence of Events screen. Click on the
Download button and review the events associated with the field contact change.
Step 3: Repeat Step 2 for each connected input.
Output Contacts
Purpose: To verify operation, labels, and logic settings of the output contacts.
Chapter Reference: Contact Inputs and Outputs
Step 1: Use the Settings Explorer in BESTCOMSPlus to open the Programmable Output, Output
Contacts screen and verify the output 1 through output 8, and output A label, energized state
label, de-energized state label, and hold attribute.
Step 2: Use the Metering Explorer in BESTCOMSPlus to open the Control, Output Override screen.
Verify the status of OUT1 through OUT8. Use the procedure outlined under Acceptance
Testing, Control Outputs to actuate selected output contacts (OUT1 through OUT8) and actually
trip or close the connected field device (circuit breaker, lockout, etc.). Verify that the selected
output has changed state on the Control, Output Override screen of BESTCOMSPlus or the
front-panel display. Return the output to its original state, verifying that the output returns to its
