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
7UM62 and the system, 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 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 initia-
tion of inadvertent switching operations by further tests.
