Changing the operating state
To change the operating state of a hardware component, click on the associated switching field in the Sched-
uled column.
Before executing the first change of the operating state the password No. 6 will be requested (if activated during
configuration). After entry of the correct password a condition change will be executed. Further state changes
remain enabled until the dialog box is closed.
Test of the Output Relays
Each individual output relay can be energized allowing a check of the wiring between the output relay of the
7VK61 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 executed without any danger
(see above under DANGER!).
• Each output relay must be tested via the corresponding Scheduled field of the dialog box.
• Finish the testing (see margin heading below „Exiting the Procedure"), so that during further testings no un-
wanted switchings are initiated.
Test of the Binary Inputs
To test the wiring between the plant and the binary inputs of the 7VK61 the condition in the system which ini-
tiates the binary input must be generated and the response of the device checked.
To do so, open the dialog box Hardware Test again to view the physical position of the binary input. The pass-
word is not yet required.
