Prepare the IED for verification of settings as outlined in 5.1 "Preparing the IED to
verify settings" .
Values of the logical signals for STBRREC (79) are available on the local HMI under
Main menu/Tests/Function status/Control/STBRREC(79,0->1)/1:STBRREC . The
Signal Monitoring in PCM600 shows the same signals that are available on the local HMI.
The purpose of verification before commissioning is to check that entered selections,
setting parameters and configuration render the intended result. The function is flexible
with many options and facilities. At commissioning only the selections and settings
intended for use are verified. If one chooses to reduce some time settings in order to
speed up verification, be careful to set the parameters at intended operational values at
the end of the verification procedure. One such parameter is the reclaim Reset time that
must be timed out before a new test can be performed.
The verification test is performed together with protection and trip functions. Figure 24
illustrates a suggested testing arrangement, where the circuit-breaker (CB) is simulated
by an external bi-stable relay (BR), for example a relay type RXMVB2 or RXMD or
Breaker Simulator from ABB.
