4. How to Program your Alpha Using the Front Keypad and LCD Screen
The α and α2 series programmable controllers can be programmed directly, using the front
keypad. It is possible to write a large program using this method. However, the amount of the
program you are able to view, while you program, is limited to the size of the LCD screen.
Hence, we advise direct programming is more useful for simple timer changes, simple
upgrades or for writing small, simple programs.
The following will guide you through programming an Alpha using the front keypad and LCD
screen. This tutorial will show you how to:
• Set the Alpha’s Time and Date using the keypad
• How to Write a Small Program using the keypad
4.1 How to Set the Alpha’s Time and Date using the Keypad
Apply power to the controller. Please consult the instructions in section 2 of this guide to
ensure this is done correctly.
Enter the menu by pressing the “ESC” and “OK” buttons simultaneously.
Use UP (▲) or DOWN (▼) to select ClockSet then press “OK”.
Press “OK” again
The second line should be flashing a date format.
Use the PLUS (+) button to select dd/mm/yyyy.
Press the DOWN (▼) button.
Use the PLUS (+) or MINUS (-) buttons to set the month.
Press the LEFT (◄)
Use the PLUS (+) or MINUS (-) buttons to set the day.
Press RIGHT (►) twice.
Use the PLUS (+) or MINUS (-) buttons to set the year.
Press the DOWN (▼) button. Now set the time using the method you learned above.
This should be in 24 hour format (eg: 11:00pm is 23:00).
The day (“Mon”, “Tues”, “Wed”) is updated from the date you set above. There is no need to
alter this.
When you are satisfied with the time and date you’ve set, press “OK”.
Now press “ESC” to return to the TopMenu.
Press “ESC” again to exit the menu. The time is now visible at the top of the screen.
