Keypad/Display Interface Test - GE ALPS Instruction Manual

8.1 INTRODUCTION
This command will test the display, keypad, and LEDs. This test does not require a specific privilege level.
A test is selected using the arrow keys followed by the [ENT] key.
If Display is chosen, the top two lines of the display will be filled to verify that all LCD dots are working. The display will
prompt the user to press the [ENT] key. The bottom two lines of the display will now be filled. This is the end of the test. If
the [CLR] key is pressed the relay screen is displayed. If the [ACT] key is pressed, the LUI TEST choices screen will be dis-
played.
If LEDs is chosen, both the STATUS and TRIP LEDs will be tested. The STATUS LED is tested first followed by the TRIP
LED. The display will indicate the correct state of the LEDs. After each LED state the user will be prompted to press the
[ENT] key and move to the next test. When the [ENT] key is pressed after the last test, the LEDs return to their pre-test
state and the LUI TEST item menu is displayed.
If Keypad is chosen, the following screen appears:
When any key is pressed, the key label will blink on the display. If another key is pressed, the new key label will blink.
Pressing the [CLR] key will terminate the keypad test and the test item menu is displayed.
This command tests the digital outputs of the relay. If the digital outputs are not enabled, the user is prompted to enable
them. If the user enters [1/Y] (YES) and presses [ENT], the outputs are enabled. If the user presses [3/N] (NO), CAN-
CELED is displayed and the test is terminated.
When the outputs are enabled, protection must be disabled (if it is currently enabled). If the user responds NO, CAN-
CELED is displayed and the test is canceled. If user responds YES, protection is turned OFF, the status LED turns RED
and the list of available tests is displayed.
To select a test item, scroll through the list using arrow keys or enter the test number. If the test pre-requisites are satisfied,
the word ON will display to the right of test item. If the password privilege level is not MASTER or communications is per-
forming an action, an error message is displayed and the test is not performed.
The contact being tested will close if it is normally open and it will open if it is normally closed. Only one output can be mon-
itored at a time. When a new output is tested, the old output will be reset.

Other activities using the [SET], [ACT] or [INF] keys may be performed at any time. When the user returns to the Digital
Output tests, they are asked questions about Protection enable and then the selected test and its following tests are dis-
played, starting from the second line.
Press the arrow keys until End Test Mode is displayed or press the [1], [ENT] keys to stop the digital output test. Press
[ENT] again. The digital output test is terminated and the following message will be displayed:
