WARNING!
Warning of dangers evolving from improper primary tests
Non-observance of the following measures can result in death, personal injury or sub-
stantial property damage.
Primary tests are only allowed to be carried out by qualified personnel, who are famil-
iar with the commissioning of protection systems, the operation of the plant and the
safety rules and regulations (switching, grounding, etc.).
3.3.1
Test Mode and Transmission Block
Activation and De-
activation
If the device is connected to a central or main computer system via the SCADA inter-
face, then the information that is transmitted can be influenced. This is only possible
with some of the protocols available (see Table „Protocol-dependent functions“ in the
Appendix A.6).
If
Test mode
is set ON, then a message sent by a SIPROTEC 4 device to the main
system has an additional test bit. This bit allows the message to be recognized as re-
sulting from testing and not an actual fault or power system event. Furthermore it can
be determined by activating the
Transmission block
that no annunciations at all are
transmitted via the system interface during test mode.
The SIPROTEC 4 System Description describes in detail how to activate and deacti-
vate test mode and blocked data transmission. Note that when DIGSI is being used,
the program must be in the
Online
operating mode for the test features to be used.
3.3.2
Checking the System (SCADA) Interface
Prefacing Remarks
If the device features a system interface and uses it to communicate with the control
center, the DIGSI device operation can be used to test if messages are transmitted
correctly. This test option should however definitely not be used while the device is in
service on a live system.
DANGER!
Danger evolving from operating the equipment (e.g. circuit breakers, discon-
nectors) by means of the test function
Non-observance of the following measure will result in death, severe personal injury
or substantial property damage.
Equipment used to allow switching such as circuit breakers or disconnectors is to be
checked only during commissioning. Do not under any circumstances check them by
means of the test function during real operation by transmitting or receiving messages
via the system interface.
