1.1 Special Features of the
α
2SeriesSystem
1) Display message and Function Block data
The
α
2 series can display the state of operation and the alarm on the LCD display as a
message. It can display the following contents by the using display function block. The
value of displayed timers and counters can be changed in the RUN mode.
- Total characters on LCD display: 12 characters
×
4 lines
- Display Items: Message, value (current or set) of timer and counter, analog values, etc
2) The programming in the personal computer is fast and easy
The programming software AL-PCS/WIN-E for Windows can make and save programs.
The programming can be done using a pictorial method in which lines are used to connect
function blocks on a programming screen.
Direct programming using the
α
2 controller front panel keys is also available.
3) LCD image send via GSM modem
The
α
2 series is able to send the LCD image as an E-mail using a GSM modem. The user
can monitor application status by accessing the diagnostic message sent as an E-mail via
GSM modem
4) Supports computer link using dedicated protocol
The
α
2 series supports computer link (dedicated protocol). User-specific application
software using computer link (dedicated protocol) can change schedule data, parameters
within Function Blocks and provide condition monitoring of the application.
5) Enhancement of clock function
The weekly timer and the calendar timer function have many switches that can be set and
provide powerful time dependant control capabilities.
6) Analog input, 0 - 10V/0 - 500:
The DC input for the
α
2 series can accept of 0 - 10V signals with a resolution of 0 - 500.
7) High speed counter, Max. 1kHz
The
α
2 series has high speed counters (Max. 2 points) when using AL2-4EX (EI1, EI2).
8) High current output capability
9) Built-in EEPROM
The built in EEPROM eliminates the need for battery backed data.
10)Supports 6 languages:
The
α
2 series supports 6 languages (English, German, French, Italian, Spanish, and
Swedish). The displayed language can be selected in the TOP MENU.
