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 Proce-
dure”), 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 7UM61 the condition
in the system which initiates the binary input must be generated and the response of
the device checked.
To do this, the dialog box Hardware Test must again be opened to view the physical
state of the binary inputs. The password is not yet required.
Proceed as follows in order to check the binary inputs:
• Each state in the plant which causes a binary input to pick up must be generated.
• The response of the device must be checked in the
Status column of the dialog box.
To do this, the dialog box must be updated. The options may be found below under
the margin heading “Updating the Display”.
• Terminate the test sequence (see below under the margin heading “Exiting the Pro-
cedure”).
If however the effect of a binary input must be checked without carrying out any switch-
ing in the plant, it is possible to trigger individual binary inputs with the hardware test
function. As soon as the first state change of any binary input is triggered and the pass-
word no. 6 has been entered, all binary inputs are separated from the plant and can
only be activated via the hardware test function.
Test of the LEDs The LEDs may be tested in a similar manner to the other input/output components. As
soon as the first state change of any LED has been triggered, all LEDs are separated
from the internal device functionality and can only be controlled via the hardware test
function. This means e.g. that no LED can be switched on anymore by e.g. a protec-
tion function or operation of the LED reset key.
Updating the
Display During the opening of the dialog box Hardware Test the operating states of the hard-
ware components which are current at this time are read in and displayed.
An update occurs:
• for each hardware component, if a command to change the condition is successfully
performed,
• for all hardware components if the Update button is clicked,
• for all hardware components with cyclical updating (cycle time is 20 seconds) if the
Automatic Update (20sec) field is marked.
Exiting the Test
Mode To end the hardware test, click on Close . The dialog box closes. The device becomes
unavailable for a brief start-up period immediately after this. Then all hardware com-
ponents are returned to the operating conditions determined by the plant settings.
