7.2 TARGETS
• How often the test is performed: Event driven. The test is performed when a device programmed to receive GOOSE
messages stops receiving. This can be from 1 to 60 seconds, depending on GOOSE packets.
• What to do: Check GOOSE setup.
TEMP MONITOR:
OVER TEMPERATURE
• Latched target message: Yes.
• Description of problem: The ambient temperature is greater than the maximum operating temperature (+80°C).
• How often the test is performed: Every hour.
• What to do: Remove the C30 from service and install in a location that meets operating temperature standards.
UNEXPECTED RESTART:
Press "RESET" key
• Latched target message: Yes.
• Description of problem: Abnormal restart from modules being removed or inserted while the C30 is powered-up, when
there is an abnormal DC supply, or as a result of internal relay failure.
• How often the test is performed: Event driven.
• What to do: Contact the factory.
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
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
7
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
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
