2.5.1Keypad Operation

Use the keypad to enter information into the controller. Some of the keys have two functions. The following gives keypad definitions and functions.

Alarm (Horn) Off Key. Press the alarm off key to silence the horn at the user’s discretion. Place the generator set master switch in the AUTO position before silencing the alarm horn. The alarm horn cannot be silenced unless the master switch is in the AUTO position. See Section 2.3.7, Controller Reset Procedure, for more information on turning the alarm horn off.

AM/PM Key. When the controller displays a question during programming requiring a nonnumeric answer (am or pm), the controller accepts the secondary key function and ignores the alarm off function of the key.

Enter ↵ Key. Press the enter ↵ key to confirm the entered information on the display when selecting menus or programming.

Lamp Test Key. Press the lamp test key to check that the status and fault lamps illuminate, the horn sounds, and the digital display clears. Press the reset menu key before pressing the lamp test key.

Menu Down ↓ Key. The controller displays consist of menus with various data levels or programming steps. Use the menu down ↓ key to navigate through the menu levels.

Note: Pressing the menu down ↓ key in some menus locks the user into that level structure of the menu where the display will not change. Press the reset menu key to access other main menus.

Menu Right → Key. Press the menu right → key to scroll through sub-levels of each main menu. The display contains an arrow in the right-hand corner when there is a sub-level. Pressing the menu right → key when no arrow is present moves to the next submenu header. Press the menu right → key prior to entering decimal values when required.

Note: Pressing the menu right → key in some menus locks the user into that level structure of the menu where the display will not change. Press the reset menu key to access other main menus.

Numeric 0-9 Keys. Press the numeric keys when selecting menus or entering numeric values during programming. The controller ignores the secondary function of the key (yes, no, etc.) when only numeric values are valid.

Reset Menu Key. The reset menu key exits a menu, clears incorrect entries, and cancels the auto-scroll function. Press the reset menu key to exit a menu or any layer within that menu.

Stop Prog Run Key. Press the stop prog run key to end the generator set programmed exercise run created in Menu 4—Operational Records. The generator set shuts down after the time delay for engine cooldown expires. The stop prog run key does not affect the programmed transfer switch exercise function.

Yes/No Keys. When the controller displays a question during programming requiring a nonnumeric answer (yes or no), the controller accepts the secondary key function and ignores the numeric value of the key. Press the ENTER key to confirm the response.
