Activating The 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)
• Using the online mode in the PCM600 configuration software
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 the test mode

Put the IED into the test mode before testing. The test mode blocks all protection functions and
some of the control 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. The busbar differential protection is not included in the test mode and is not prevented
to operate during the test operations. The test switch should then be connected to the IED.Test
mode is indicated when the yellow PickupLED flashes.
1. Select Main menu/Tests/IED test mode/TESTMODE:1
2. Set parameter
3. Save the changes.
As a consequence, the yellow pickupLED 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.
