Figure 3-24 Test of the Binary Inputs and Outputs — Example
To change the operating state of a hardware component, click on the associated
switching field in the Scheduled column.
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
box is closed.
Each individual output relay can be energized allowing a check of the wiring between
the output relay of the 7UT613/63x 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-
ed without any danger (see above under DANGER!).
• Each output relay must be tested via the corresponding Scheduled cell in the
dialog box.
• Finish the testing (see margin heading below „Exiting the Procedure"), so that
during further testings no unwanted switchings are initiated.
To test the wiring between the plant and the binary inputs of the 7UT613/63x the con-
dition in the system which initiates the binary input must be generated and the re-
sponse of the device checked.
To do so, open the dialog box Hardware Test again to view the physical position of
the binary input. The password is not yet required.
