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 dialogue
box. To do this, the dialogue box must be updated. The options may be found below
under the margin heading ”Updating the Display”.
• Finish the testing (see margin heading below "Exiting the Procedure").
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 implies that no LED can be switched on anymore by e.g. a protection
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 Updatebutton 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.
3.3.5 Testing User-Defined Functions (CFC logic)
The device has a vast capability for allowing functions to be defined by the user, espe-
cially with the CFC logic. Any special function or logic added to the device must be
checked.
Naturally, general test procedures cannot be given. Rather, the configuration of these
user-defined functions and the necessary associated conditions must be known and
verified. Possible interlocking conditions of switching devices (circuit breakers, discon-
nectors, earth switch) are of particular importance. They must be considered and
tested.
3.3.6 Trip/Close Tests for the Configured Operating Devices
Control by Local
Command If the configured operating devices were not switched sufficiently in the hardware test
already described, all configured switching devices must be switched on and off from
the device via the integrated control element. The feedback information of the circuit
