Section 10 1MRK 505 304-UUS - Testing functionality by secondary injection 10.11 Station communication 10.11.1 Multiple command and transmit MULTICMDRCV / MULTICMDSND The multiple command and transmit function (MULTICMDRCV / MULTICMDSND) is only applicable for horizontal communication. Test of the multiple command function block and multiple transmit is recommended to be performed in a system, that is, either in a complete delivery system as an acceptance test (FAT/SAT) or as parts of that system, because the command function blocks are connected in a delivery-specific way between bays and the station level and transmit.

Section 11 1MRK 505 304-UUS - Primary injection testing Section 11 Primary injection testing Whenever it becomes necessary to work on primary equipment, it is essential that all the necessary switching, locking, grounding and safety procedures are observed and obeyed in a rigid and formalized manner. Operating and testing procedures should be strictly followed in order to avoid exposure to live equipment.

Section 11 1MRK 505 304-UUS - Primary injection testing Testing will be explained from one general current input CTx (that is, x = 1, 2,..., Nmax; where Nmax is equal to the maximum number of used CT inputs). Follow the following test instructions for all used current inputs in an IED. Procedure Connect the test set for injection primary current to the main CT connected to the current terminals of CTx input of the IED as shown in figure 25.

Page 162 Section 11 1MRK 505 304-UUS - Primary injection testing Check that the current is present only in the phase being tested. Switch the current off. Check the function in phases B and C by injecting current in the same way. In busbar arrangements where a disconnector replica is used, it provides the information to the busbar protection about which of the measured CT currents shall be included within different differential zones.
Page 163: Section 12 Commissioning And Maintenance Of The Fault Clearing System
The periodicity of all tests depends on several factors, for example the importance of the installation, environmental conditions, simple or complex equipment, static or electromechanical IEDs, and so on. The normal maintenance practices of the user should be followed. However, ABB's recommendation is as follows: Every second to third year Busbar protection REB670 2.0 ANSI...

Section 12 1MRK 505 304-UUS - Commissioning and maintenance of the fault clearing system 12.2.2.7 Measurement of service currents After a maintenance test it is recommended to measure the service currents and service voltages recorded by the protection IED. The service values are checked on the local HMI or in PCM600.

Page 173: Repair Instruction
Operation may be disrupted and IED and measuring circuitry may be damaged. An alternative is to open the IED and send only the faulty circuit board to ABB for repair. When a printed circuit board is sent to ABB, it must always be placed in a metallic, ESD-proof, protection bag.

13.4 Repair support If an IED needs to be repaired, the whole IED must be removed and sent to an ABB Logistic Center. Please contact the local ABB representative to get more details. 13.5 Maintenance The IED is self-supervised.
