Synchrocheck and energizing check (SYN)

Testing the energizing check

During test of the energizing check function for a single bay arrangement, these voltage inputs
are used:
U-line UL1, UL2 or UL3 voltage input on the terminal.
U-bus U5 voltage input on the terminal
At test of the energizing check function for a 1 1/2 CB diameter the following alternative voltage
inputs can be used for the three energizing check functions. The voltage is selected by activation
of different inputs in the voltage selection logic:
SYN1 U-line
U-bus
SYN2 U-line
U-bus
SYN3 U-line
U-bus

Testing the dead line live bus (DLLB)

The test should verify that the energizing function operates for a low voltage on the U-Line and
for a high voltage on the U-bus. This corresponds to an energizing of a dead line to a live bus.
The settings in table 12can be used during the test if the final setting is not determined.
