Values of the logical signals for STBRREC are available on the local HMI under Main menu/
Tests/Function status/Control/STBRREC(79,0->1)/STBRREC:1. 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 Reclaim 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
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.

Figure 18: Simulating the CB operation by a bi-stable relay/breaker simulator and
manual switches
The following manual switches are used:
•
Switch or push-button to close (SC)
•
Switch or push-button to trip (ST)
•
Switch for CB ready condition (SRY)
If no bi-stable relay or breaker simulator is available, replace it with two self-reset auxiliary
relays and use a self-holding connection.
Use a secondary injection IED test set to operate the protection function. The test set shall be
switched off when a trip signal is given or when the BR comes to open position to simulate real
conditions.
