1.1 Special Features of the α2 Series System
1) Display message and Function Block data
The
α2 series can display the state of operation and the alarm on the LCD display as a
message. It can display the following contents by using the 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 create 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
α2 controller front panel keys is also available.
3) LCD image send via GSM modem
The
α2 (AL2-14MR-*,AL2-24MR-*) 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
α2 (AL2-14MR-*,AL2-24MR-*)series supports computer link (dedicated protocol).
User-specific application software using computer link 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, -50
°C - 200°C (PT100), -50°C - 450°C (K-type thermocouple):
The DC input for the
α2 series can accept of 0 - 10V signals with a resolution of 0 - 500.
7) Analog output,
0 - 4000/0 - 10V, 0 - 2000/4 - 20mA:
The
α2 series can output voltage and current signals.
8) High speed counter, Max. 1kHz
The
α2 series has high speed counters (Max. 2 points) when using AL2-4EX (EI1, EI2).
9) High current output capability
10)Built-in EEPROM
The built in EEPROM eliminates the need for battery backed data.
11)Supports 7 languages:
The
α2 series supports 7 languages (English, German, French, Italian, Spanish, Swedish,
and Russian
*1
). The displayed language can be selected in the TOP MENU.
*1 V3.00 or later
