Testing and Maintenance
BE1-951
If this relay is being installed in an existing installation, please be aware of the equipment monitoring features
of this device, especially if the monitoring logic will be utilized. Please make note of any pretest operation
levels, duty levels, etc. on existing equipment (e.g., breakers or transformers). As the user, you may make
the determination of what values the relay should have as initial monitoring values when the relay is placed
in service.
Also, please be aware that because of the multi-function nature of the BE1-951 relay, it may on occasion
be necessary to temporarily disable some of the protective elements while testing the relay to facilitate
isolated testing of individual functions. Always remember to enable these functions before placing the relay
in service.
To assist you in the commissioning testing of this relay, you may at any time refer to Section 6,
Reporting
and Alarm Functions for various means of reporting status, alarms, and targets.
Please refer to the other sections of the instruction manual for assistance on any particular functions of
the relay. 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 contact sensing input label assignments and recognition and debounce settings.
Reference Commands: SN-IN, SG-IN
Step 1 Transmit the SN-IN1 command to verify the input 1 user-defined name, TRUE label, and FALSE
label.
Step 2 Repeat Step 1 for each of the remaining contact sensing inputs. Add the number of an input to
the SN-IN command to check that input's name and labels.
Step 3 Verify the recognition and debounce settings for each contact sensing input by using the SG-IN
command. When the SG-IN command is transmitted, the relay responds with the recognition and
debounce settings for each input. Reported settings use the format SG-IN#=recognition,
debounce.
Step 4 Transmit the RG_STAT command to the relay or use HMI screen 1.4.1 to verify the status of
input 1. Transmit the RS-NEW=0 command to the relay. From the actual field device, close (or
open) the specific contact that supplies relay Input 1. While maintaining contact position, verify
that Input 1 has changed state by transmitting the RG-STAT command or using HMI screen
1.4.1. Return the field contact to its original state, verifying that Input 1 returns to its original
state. Transmit the RS-NEW command to the relay and review the event record associated with
the field contact change.
Step 5 Repeat Step 4 for each connected input.
Output Contacts
Purpose: To verify output contact settings and output contact logic settings.
Reference Commands: SN-VO, SL-VO, SG-HOLD
Step 1 Transmit the SN-VOA command to verify the virtual output A user-defined name, TRUE label,
and FALSE label.
Step 2 Repeat Step 1 for virtual outputs 1 through 15. Add the number of an output to the SN-VO
command to check that output's name and labels.
Step 3 Transmit the SL-VO command to obtain a list of all virtual outputs and their Boolean logic
equations. Verify that the desired virtual output equations match the reported equations.
Step 4 Verify the programmable hold timer setting for each hardware output by transmitting the
command SG-HOLD. The output hold timer setting for each output is reported as enabled (1) or
disabled (0).
Step 5 Verify the output contact activity by viewing the sequence of events reports with the RS-###
command.
