Before executing the first change of the operating state the password No. 6 will be re-
quested (if activated during configuration). After entry of the correct password a con-
dition change will be executed. Further state changes remain enabled until the dialog

Test of the Output
Each individual output relay can be energized allowing a check of the wiring between

the output relay of the 7SD610 and the plant, without having to generate the message
that is assigned to the relay. As soon as the first change of state for any of the output
relays is initiated, all output relays are separated from the internal device functions,
and can only be operated by the hardware test function. This means, that e.g. a TRIP
command coming from a protection function or a control command from the operator
panel to an output relay cannot be executed.
Proceed as follows in order to check the output relay:
• Make sure that the switching operations caused by the output relays can be execut-
