6.4.3. MIMIC test
The test mode for MIMIC is entered by setting the “Panel test” parameter to “Start”
in
MAIN MENU/Tests/Mimic
[17]. The test can be interrupted by pressing any
button. Otherwise the test is the same as the one run at power up (refer to section
“Display test at power up” on page 11).
6.4.4. I/O test
The test mode is for testing digital inputs and outputs and their effect on the function
of the terminal. The user has to enter the test mode (
MAIN MENU/Tests/
General/Test mode
) before testing or else the changes will not be valid. When
the test mode is active, status changes of the objects in the MIMIC view will not take
place. The test mode is cancelled by setting the “Test mode” parameter to “Not
active” or by power up.
If the user forgets to cancel the test mode, it remains on and the Ready
LED indicator remains flashing.
The virtual SNVT inputs and outputs can be tested with or without the test
mode. Note, however, that the test values remain valid until real changes
in the SNVT inputs and outputs are caused by the application.
To test inputs or outputs
1. At technical level, select
MAIN MENU/Tests/General/Test mode
2. Set the “Test mode” parameter to “Active” and press [E] to confirm
3. Return to the previous menu (Tests), select the input/output card to be tested and
move to the selected card menu
4. Select the parameter and enter the setting mode
5. Change the state of one or more inputs/outputs from 0 to 1 or vice versa
6. Press [E] to confirm
6.4.5. IRF test
The user has to enter the test mode (
MAIN MENU/Tests/General/Test
mode
) before testing the IRF state. IRF is activated by setting the parameter
“Activate IRF” (
MAIN MENU/Test/General/Activate IRF)
to
“Activate IRF”. This will release the IRF relay contact and send the IRF error
activated event (E57).
The test mode is cancelled by setting the “Test mode” parameter to “Not active” or
by powering up the relay. If the user does not cancel the test mode, it remains on and
the Ready LED indicator remains flashing.
