Activating Test Mode - ABB Relion 650 Series Commissioning Manual

Section 6
Testing IED operation
• Calculated settings
• Valid configuration diagram for the IED
• Valid terminal diagram for the IED
• Technical manual
• Three-phase test equipment
Content of the technical manual.
• Application and functionality summaries
• Function blocks
• Logic diagrams
• Input and output signals
• A list of setting parameters
• Technical data for the function
The test equipment should be able to provide a three-phase supply of currents and three-
phase voltage. The magnitude and angle of currents (and voltages) should be possible to vary.
Check that the IED is prepared for test before starting the test session. Consider the logic
diagram of the function when performing the test.
The response from a test can be viewed in different ways.
• Binary output signals
• Service values in the local HMI (logical signal or phasors)
• A PC with PCM600 (configuration software) in debug mode
A mechanism for limiting the number of writings per time period is included in the IED to
prevent the flash memory to be worn out due to too many writings. As a consequence it may
take up to an hour to save changes. If the auxiliary power is interrupted before a change is
saved, that change is lost.
6.2

Activating test mode

Put the IED into the test mode before testing. The test mode blocks all functions in the IED,
and the individual functions to be tested can be unblocked to prevent unwanted operation
caused by other functions. In this way, it is possible to test slower back-up measuring
functions without the interference from faster measuring functions. Test mode is indicated
when the yellow Start LED flashes.
Procedure
1. Select Main menu/Tests/IED test mode/1:TESTMODE
2. Set parameter
3. Save the changes.
As a consequence, the yellow Start LED starts flashing as a reminder and remains
flashing until the test mode is switched off.

Do not switch off the auxiliary power supply to the IED before changes, for
example, setting parameter or local/remote control state changes are saved.
