Testing the binary
inputs
To check the wiring between the plant and the binary inputs of the central unit, you
must create in the plant itself the cause for an external and read out the effect at the
device itself.
To do so, open the dialog box
Test devices in and outputs
again to view the phys-
ical position of the binary input. The password is not yet necessary.
Activate in the plant each of the functions which cause an external trip signal at the
binary inputs
Check the reaction in the
Actual
column of the dialog box. To do so you must
update the dialog box. You will find the possibilities below under the margin heading
“Updating the display“.
If you want to check the effects of a binary input without actual switching operations
in the plant, you could do so by controlling individual binary inputs with the hardware
test. As soon as you have initiated the first state change for any binary input and have
entered the password No. 6,
all
binary inputs are disconnected from the device and
can only be operated by the hardware test functions.
Finish the testing (see margin heading below “Finishing the process“).
Checking the LEDs
You can check the LED in the same way like the other in/output components. As soon
as you have initiated the first state change for any LED,
all
LEDs are disconnected
from the functionality of the device and can only be operated by the hardware test
function. This means e.g.that no LED is illuminated anymore by a protection function
or by pressing the LED reset button.
Updating the dis-
play
During the opening of the dialog box
Test devices in and outputs
the operating
states of the hardware components which are current at this time are read in and dis-
played. An update is made:
•
for the particular hardware component, if a command for the change on a other
state was successful.
•
for all hardware components by clicking the box
Update
,
•
for all hardware components by cyclic updating (cycle time is 20 seconds) by high-
lighting the option
Automatic Update
Finishing the
process
To finish the process, click
Close
The dialog box is closed. The hardware components
are again reset to the original operating state determined by the plant conditions. The
device is not ready for operation for a short time during the following start-up.
Caution!
Executing the commands
Reset
or
Resume
will clear all device buffers and Oscillo-
graphic Records. Before initial start you may want to back-up the settings and buffer
contents by means of the DIGSI Device Configuration (see Chapter 6.2, page 212).
