UPDATING FIRMWARE AND SOFTWARE
Future enhancements to relay functionality may make a firmware update desirable. Enhancements to
relay firmware typically coincide with enhancements to BESTCOMS software for that relay. When a relay
is updated with the latest version of firmware, the latest version of BESTCOMS software should also be
obtained.
Updating Relay Firmware
If a firmware upgrade is desired, you may request a CD-ROM containing the latest firmware or download
the firmware from the Basler Electric Web site. Direct your web browser to
http://www.basler.com/BE1_Firm/ and complete the online form to request a CD-ROM containing the
latest firmware or a password for downloading firmware from the Basler Electric Web site.
Once the appropriate firmware is obtained, it can be uploaded to a relay using the BESTload software
utility provided on the CD-ROM originally supplied with the relay.
Updating BESTCOMS Software
Firmware enhancements often include the addition of relay settings or the modification of existing
settings. BESTCOMS software is revised to accommodate the new or changed settings. When firmware
is updated, the latest version of BESTCOMS should also be obtained. If a CD-ROM containing firmware
was obtained from Basler Electric, then that CD-ROM will also contain the corresponding version of
BESTCOMS software. BESTCOMS can also be downloaded from the Basler Electric Web site
(http://www.basler.com). An on-line form can be completed to obtain a password for downloading
BESTCOMS from the Basler Electric Web site.
FUNCTIONAL TESTING
Functional testing is a way to assess this relay's suitability for your application. Functional testing goes
beyond the more basic tests found in acceptance testing, but lacks the detailed function testing that is
part of the commissioning process.
Test each of the following functions to verify that this relay measures accurately, is within specified
tolerances, and operates correctly. These tests are also suitable for assisting in systematic
troubleshooting in the event that an operation is questioned. Revisiting the test of a specific function can
help verify whether the relay is operating within specified tolerances. For further assistance, contact
Basler Electric, Technical Support Services Department.
Test connections referred to in this section are for an H1 case relay. Refer to
Figure 13-1 (H1 case) for
terminal locations. If testing a relay in an S1 case, modify the current and potential test connections
according to the terminal locations shown in
Figure 13-2 (S1 case) or 13-3 (S1 Double-End Case).
The Access command (A=) and the Exit with Save commands (E and Y) are shown in the initial logic
setup table found in each test section. In order to include multiple test settings in each operational setting
table, the "access”, and "exit with save" commands are not included. However, "access" and "exit with
save" are required each time a logic or operational setting is changed.
To accelerate the testing process, two protection elements may have the same setting and are tested at
the same time but with different outputs. During the pickup/dropout test, one of the elements could pick
up slightly ahead of the other, resulting in only one target being displayed. At some point in the test, apply
110% of the pickup value and verify that both targets display. Reset targets prior to each test by pressing
the HMI Reset key.
NOTE
Functional testing is NOT required for this device. It is necessary only when
performing a comprehensive assessment to determine suitability for an
application.
