Type: minor
Target: latched
Message: "WRONG TRANSCEIVER"
A webpage "SFP Transceiver Information" is provided. This page displays the type of the SFP in it. This data is to be used
with the CPU type to know the cause of the problem.
e) SFP X MODULE FAIL MESSAGES
Description: A faulty SFP or unplugging the SFP would generate this self test.
Type: minor
Target: self reset
Message: SFP MODULE x FAIL
The webpage "SFP Transceiver Information" described in the previous section applies for this self test as well. The "SFP
Module Fail" has higher priority and it suppresses the "Ethernet Fail" target message. The "SFP MODULE FAIL FUNC-
TION" setting enables/disables this self test. The target for this self test is priority-based, with the third one being the high-
est priority. For example, if all three SFP modules fail, then the third SFP target is activated. If the third SFP module failure
resolves, then the second SFP target is activated.
HARDFIBER SELF-TEST ERROR MESSAGES
In addition to those provided by the standard UR-series devices, the UR devices implement HardFiber self-tests. These are
listed below. Any abnormal diagnostic condition indicated by the LEDs or the critical failure relay also results in a self-test
message, so troubleshooting is described here. For other relays, such at the B95
Plus
, see that product’s instruction manual.
Equipment Mismatch Major Self-Test
Description: The number or type of installed hardware modules does not match the order code stored in the CPU. The stan-
dard UR-series Equipment Mismatch self-test is extended to cover the possible presence of a Process Card.
Severity: Protection is not available and all contact outputs and shared outputs are de-asserted.
If this message appears, check all modules against the order code. Ensure they are inserted properly, and cycle the control
power. If a module has intentionally been added or removed use the
Update Order Code
command to notify the relay that
the current module configuration is correct.
Module Failure Major Self-Test
Description: UR-series device module hardware failure detected.
Severity: Protection is not available and all contact outputs and shared outputs are de-asserted.
If this message appears, contact the factory and supply the failure code noted in the display. Text in the message identifies
the failed module (for example, H81). If operated on a Process Card failure, the Module Fail self-test seals-in (latches) till
the UR-series device is restarted.
Process Bus Failure Major Self-test
Description: Mission critical data is not available via the process bus. An AC quantity is considered critical if both AC bank
origins and the crosschecking settings are other than none. This self-test is also initiated by an AC input discrepancy being
detected. See the description of the crosschecking setting in this manual for further information. In addition, this self-test
can be initiated by user logic responding to loss of critical contact input/output or other data using the
Process Bus Failure
Operand
user-programmable self-test setting. This setting is located in the
Settings > Product Setup > User-Program-
mable Self Test
menu.
Severity: Protection is not available and all contact outputs and shared outputs are de-asserted.
If this message appears, first rectify any Process Bus Trouble and Brick Trouble self-test errors. Check the actual value of
the operand referenced by the
Process Bus Failure Operand
setting, and if “On”, determine the cause and rectify.
Should the problem persist with the foregoing all clear, the cause must be an AC input discrepancy, which is typically the
result of problems in the input signals to the Bricks, or faults in the Brick input conditioning hardware. If the error was
annunciated the first time significant signal was encountered, suspect the former cause and check the copper connections
external to the Brick. Where multiple UR-series devices have self-test errors, look for common causes.
