Application manual

When the setting Operation is set to Off, the behavior is set to Off and it is not possible to

override it. When a behavior of a function is Offthe function will not execute.

When IEC 61850 Mod of a function is set to Off or Blocked, the Start LED

on the LHMI will be set to flashing to indicate the abnormal operation of

The IEC 61850-7-4 gives a detailed overview over all aspects of the test mode and other

states of mode and behavior.

When the Beh of a component is set to Test, the component is not blocked and all

control commands with a test bit are accepted.

When the Beh of a component is set to Test/blocked, all control commands with a test

bit are accepted. Outputs to the process via a non-IEC 61850 link data are blocked by

the LN. Only process-related outputs on LNs related to primary equipment are

blocked. If there is an XCBR, the outputs EXC_Open and EXC_Close are blocked.

When the Beh of a component is set to Blocked, all control commands with a test bit

are accepted. Outputs to the process via a non-IEC 61850 link data are blocked by the

LN. In addition, the components can be blocked when their Beh is blocked. This can

be done if the component has a block input. The block status of a component is shown

as the Blk output under the Test/Function status menu. If the Blk output is not shown,

the component cannot be blocked.

Setting guidelines

There are two possible ways to place the IED in the TestMode= Enabled" state. If, the IED

is set to normal operation (TestMode = Disabled), but the functions are still shown being

in the test mode, the input signal INPUT on the TESTMODE function block might be

activated in the configuration.

Forcing of binary input and output signals is only possible when the IED is in IED test

Time synchronization TIMESYNCHGEN

Use time synchronization to achieve a common time base for the IEDs in a protection and

control system. This makes it possible to compare events and disturbance data between all

IEDs in the system. If a global common source (i.e. GPS) is used in different substations

for the time synchronization, also comparisons and analysis between recordings made at
