Starting up
Setting up the PC to access the IED via a network
The same method is used as for connecting to the rear port.
5.6
Writing an application configuration to the IED
When writing a configuration to the IED with PCM600, the IED is automatically set in configuration
mode. When the IED is set in configuration mode, all functions are blocked.
When the configuration is written and completed, the IED is automatically set into normal mode. For
further instructions please refer to the users manuals for PCM600.
5.7
Using the RTXP test switch
The RTXP test switch is designed to provide the means of safe testing of the IED. This is achieved
by the electromechanical design of the test switch and test plug handle. When the test plug handle is
inserted, it first blocks the trip and alarm circuits then it short circuits the CT secondary circuit and
opens the VT secondary circuits making the IED available for secondary injection.
When pulled out, the test handle is mechanically stopped in half withdrawn position. In this position,
the current and voltage enter the protection, but the alarm and trip circuits are still isolated and the
IED is in test mode. Before removing the test handle, check the measured values in the IED.
Not until the test handle is completely removed, the trip and alarm circuits are restored for operation.
Trip and alarm circuits
1.
Check that the correct types of contacts are used.
5.8
Checking the binary input/output circuits
5.8.1
Binary input circuits
Preferably, disconnect the binary input connector from the binary input cards. Check all connected
signals so that both input level and polarity are in accordance with the IED specifications.
5.9
Checking optical connections
Check that the optical connections are correct.
30
The PC and IED must belong to the same subnetwork for this set-up to work.
Verify that the contact sockets have been crimped correctly and that they are fully
inserted by tugging on the wires. Never do this with current circuits in service.
Do not insert anything else to the female connector but the corresponding male
connector. Inserting anything else (such as a measurement probe) may damage the
female connector and prevent a proper electrical contact between the printed circuit
board and the external wiring connected to the screw terminal block.
