By using the signals and displays generated by the P632, it is possible to determine whether the P632 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 the circuit breaker to operate during protection testing, the trip commands can be blocked through MAIN: Trip cmd.block. USER (Par/Func/Glob menu branch) 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 menu branch) or an appropriately configured binary signal input. Selection of the trip command from the integrated local control panel is password-protected (see Chapter “Password-Protected Control Actions”).

If the P632 is connected at substation control level, the user is advised to activate the test mode via MAIN: Test mode USER (Par/Func/Glob menu branch) or an appropriately configured binary signal input. The telegrams are then identified accordingly (reason for transmission: test mode).
