3.5.2 COMMUNICATE
Select Communicate to establish communication with the connected relay. Set the front panel COMMUNICATION switches
to 9600 baud, address 1, test = ON, then apply power to the relay. When successful communications is established, a mes-
sage will be displayed near the bottom of the screen. If the message indicates unsuccessful communications, check com-
munication switch settings and wiring connections between the relay, computer and RS232/485 converter. Also ensure that
the correct computer COM port is being used. When communications is established, the screen displays menus with Status
selected.
3.5.3 SETPOINTS EDITOR
SETPOINTS EDITOR > FILE > OPEN:
Retrieve a setpoint file from the disk. All relay values, with the exception of actual dial settings, can be modified and saved
back to disk either as the same file or as a new one. This is useful for creating different relay setups.
Starting from version D1.3, a File List Window will pop up to select a setpoint file. The File List window displays file names
in the current directory, the parent directory, and all subdirectories. You can enter a file name explicitly or enter a file name
with standard DOS wildcards (
*
and
?
) to filter the names appearing in the window. You can use arrows to select a file
name, and then press Enter to open it. You can also double click your left mouse button to open any file displayed in the
window.
SETPOINTS EDITOR > FILE > NEW:
Loads factory default settings into the computer memory. These can be used as a starting point for making new relay set-
ups.
SETPOINTS EDITOR > FILE > SAVE:
Saves the settings in the computer memory to the file on the currently selected disk which was originally loaded. The origi-
nal file is overwritten.
SETPOINTS EDITOR > FILE > SAVE AS:
Saves the settings in the computer memory to a new file. A File List window, identical to the one in
Setpoints > File > Open
, will pop up to enter a new file name to be saved to the disk.
SETPOINTS EDITOR > FILE > PRINT:
Print all the settings in the computer memory to obtain a hard copy. A File List window identical to the one in
Setpoints > File > Open
will pop up to select the file to print.
SETPOINTS EDITOR > FILE > COMMENT:
User comments typed with this menu selection will be added to the saved file and printed out on a hardcopy. This is useful
for documenting relay types and comments for a specific application.
SETPOINTS EDITOR > SETPOINTS > SIMULATED DIALS:
To create a relay simulation setup using simulated protection settings from the computer instead of the relay dials them-
selves enter the required settings with this menu. After saving entered values different simulation setups can be recalled
later with
Setpoints > File > Open
menu to save having to re-enter different test settings.
SEPOINTS EDITOR > SETPOINTS > SIMULATED CURRENTS:
Required currents for a specific test are entered using this menu. When used in conjunction with the simulated dials menu,
a complete test setup can be created. Once the required setup has been entered in the computer memory, use
Setpoints > File > Save As
to save to a file for later recall and downloading to the relay being tested.
RETURN:
When using a mouse, click on this menu to move cursor up to the next higher menu level. This selection is the same as
pressing the ESCAPE key.
