3. Type in the current password and click OK. If the password is not known, refer to Chapter 8: LOCAL USER
INTERFACE for details on displaying the current password.
4. ALPS-Link prompts for the unit ID. Type 0 and press TAB.
5. Select OK. ALPS-Link responds with the message SUCCESSFUL LOGIN. If this was an initial login, you
must log out at this point and log in again, in order to get a complete display of all the LPS-D menus.
6. Select Logout from the Device menu and select OK.
h) SETTING CHANGES
Setting changes required for a particular test are listed before the test. A setting can be changed either by cat-
egory or individually, by selecting either Device > Settings or Device > Local Settings from the ALPS-Link
menu bar. Informatin on changing settings is provided in Chapter 11: ALPS-LINK USER GUIDE.
It is important to remember to click End from the LPS-D Settings list menu after all settings changes for a par-
ticular test are complete. This is necessary because settings are stored in a buffer so that they can all be down-
loaded at once. Clicking End changes the settings in the relay itself.
i) ENTERING TEST MODE
Before most tests it is necessary to set the relay in test mode according to the function to be tested. The test
mode is set as follows:
1. Select Change Access Level from the Actions menu.
2. Enter the Control Level password. If the password is not known, see Chapter 8: LOCAL USER INTER-
FACE for details on viewing the current password.
3. When the password is accepted, the message CONTROL LEVEL appears at the bottom of the screen.
4. Select Relay Test Mode from the LPS Actions menu. The Relay Test list box appears.
5. Select the test you wish to enter from the menu and then select OK.
6. The Status LED changes from green to red when the LPS-D is in test mode.
j) EXITING TEST MODE
To end test mode and turn relay protection on, select End Test Mode from the Relay Test list box and then
select OK. The Status LED changes from red to green, indicating that normal operation has resumed.
k) INITIAL TEST SETUP
Before beginning a test, the relay settings should be checked for reference and verification. The factory set-
tings are listed in Chapter 2: CALCULATION OF SETTINGS. You may use either the communications ports or
scroll through the settings to ensure they all match the defaults.
For testing with ALPS-Link, the relay settings should be uploaded from the LPS-D and printed for reference
and verification. Verify that each LPS-D setting matches the default setting listed. If no printer is available, use
the Device > Settings command for verification.
Once uploaded, the current LPS-D settings can be saved to a disk file so that they can be downloaded to the
LPS-D when testing is completed. Click Save LPS in the LPS-D Settings window. ALPS-Link prompts for a
name for the file, after which you should enter a valid MS-DOS filename. More information on how to use this
command can be found in Chapter 11: ALPS-LINK USER GUIDE.
