Changing the Operating State
To change the status of a hardware component, click on the associated button 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 status change will be executed. Further status changes remain
possible while the dialog box is open.
Test of the Output Relays
Each individual output relay can be energized allowing to check the wiring between the output relay of the
7SC805 and the system, without having to generate the message that is assigned to the relay. As soon as the
first status change for any one 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.
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.
• Finish the testing (see margin title below „Exiting the Test Mode“), so that during further testings no unwant-
ed switchings are initiated.
