8.1.11 ACTIONS
The [ACT] key is used to select Action Commands. All Action Commands except LUI Test require either CONTROL or
MASTER privilege level. The KEYPAD/DISPLAY INTERFACE Test can be performed with any privilege level. The PASS-
WORD ENABLE/DISABLE command and all relay tests require MASTER privilege level.
When the [ACT] key is pressed, the relay requests a password. The cursor will be located at the beginning of the third line.
A password may be entered and the [ENT] key pressed. If the [ENT] key is pressed without entering a password, the cur-
rent privilege level is retained and the [ACT] command category menu is displayed. When a password is entered, each
character of the password is echoed on the display as an asterisk (*). When the [ENT] key is pressed, the password is
checked for validity. If the password is not valid, an error message is displayed which must be cleared with the [CLR] key.
When the error message has been cleared, the password can be re-entered. If the password is valid, the privilege level is
set accordingly.
The ALPS requests a password only when the privilege level is not CONTROL or MASTER at the time the [ACT]
key is pressed. When the relay is shipped from the factory, the CONTROL, SETTING and MASTER passwords are
loaded with factory values. Selecting these default passwords does not increase privilege level. Higher privilege
levels are obtained only after the factory passwords have been changed.
The following list describes the available ALPS actions:
The display will be similar to the settings display. The first line will display ACTIONS when in the Actions menu. The next
three lines will contain the ACTIONS commands. Other menu items are selected by pressing the
↑
and
↓
keys. To go
directly to a menu item, type the menu item number. The menu item number will appear in the right corner of the top line. If
the number is valid when the [ENT] key is pressed, the cursor will be positioned on that action category. If the number is
invalid when the [ENT] key is pressed, an error message will be displayed which must be cleared by the [CLR] key.
When an action category has been selected, press the [ENT] key. The first item in the selected category is displayed. The
displayed list can be scrolled through with the arrow keys. To select another actions category, press the [ACT] key and
repeat the previous steps.
8.1.12 DISABLE OUTPUTS
This command inhibits the relay from energizing any of the Digital Output contacts except for the critical alarm and power
supply alarm outputs.
The relay will ask whether to disable the outputs. Press the [3/N] key for NO or the [1/Y] for YES followed by the [ENT] key.
If NO is selected, CANCELED is displayed and no ALPS action occurs. If YES is selected, two tests are performed: CON-
TROL or MASTER privilege level is verified and communication must not be in the process of performing an action. If the
test fails then an error message is displayed and the action is not performed. If the test passes, the action is performed,
