Test of the Binary Inputs and Outputs — Example
Changing the Operating State
To change the condition of a hardware component, click on the associated switching field in the Scheduled
column.
Password No. 6 (if activated during configuration) will be requested before the first hardware modification is
allowed. After entry of the correct password a condition change will be executed. Further condition changes
remain possible while the dialog box is open.
Test of the Binary Outputs
Each individual output relay can be energized allowing a check of the wiring between the output relay of the
7VE61 and 7VE63 and the system, without having to generate the messages that are assigned to the relay.
However, this does not apply for both CLOSE relays BO1 and BO2 with configuration of a 1
1
/
2
channel opera-
tion with 7VE61 or a two-channel with 7VE63, because these relays must be controlled via a cross of both
measurement procedures.
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:
•
Ensure that the switching of the output relay can be executed without danger (see above under
DANGER!).
•
Each output relay must be tested via the corresponding Scheduled-cell in the dialog box.
•
The test sequence must be terminated (refer to margin heading “Exiting the Procedure”), to avoid the
initiation of inadvertent switching operations by further tests.
Test of the Binary Inputs
To test the wiring between the plant and the binary inputs of the 7VE61 and 7VE63 the condition in the plant
which initiates the binary input must be generated and the response of the device checked.
