C232-302-401/402/403/404-603 / C232/EN M/A23
After the settings have been made, the following checks should be carried out again
before blocking is canceled:
Has the appropriate bay type been configured?
Does the function assignment of the binary signal inputs agree with the terminal
connection diagram?
Has the correct operating mode been selected for the binary signal inputs?
Does the function assignment of the output relays agree with the terminal connection
diagram?
Has the correct operating mode been selected for the output relays?
Have the interlocking equations and the external interlocking inputs been configured
correctly?
Have all settings been made correctly?
Now the blocks can be cleared as follows ('Par/Func/Glob/' folder):
OUTP: Outp.rel.block USER
MAIN: Trip cmd.block USER
MAIN: Device on-line "Yes (on)"
MAIN: Syst.IN Enabeld USER "Yes (on)"
Tests
By using the signals and displays generated by the C232, it is possible to determine
whether the C232 is correctly set and properly interconnected with the station. Signals
are signaled by output relays and LED indicators and entered into the event memory. In
addition, the signals can be checked by selecting the appropriate signal in the menu
tree.
If the user does not wish to operate the circuit breaker during the protection functions
test, the trip commands can be blocked through MAIN: Trip cmd. block. USER
('Par/Func/Glob/' folder) or an appropriately configured binary signal input. If circuit
breaker testing is desired, it is possible to issue a trip command for 100 ms through
MAIN: Man. trip cmd. USER ('Oper/CtrlTest' folder) or an appropriately
configured binary signal input. Selection of the trip command from the integrated local
control panel is password-protected (see Section Password-Protected Control Actions in
Chapter 6).
Note: The manual trip command is only executed if it has been configured for trip
command 1 or 2.
If the C232 is connected to substation control level, it is advisable to activate the test
mode via MAIN: Test mode USER ('Par/Func/Glob/' folder) or an appropriately
configured binary signal input. The telegrams are then identified accordingly (cause of
transmission: test mode).
