The AL2-GSM. 4 Alpha XL GSM Controllers
Quick Start Guide
Please ensure you read the full Mitsubishi Alpha XL
Programming and installation guide to gain a full
understanding of the basic functionality and
programming of the Alpha. This quick guide relates only
to the GSM based functions that utilise the AL2-GSM
Module designed to fit within the expansion cover of the
Alpha.
Note: The AL2-GSM module is only suitable for DC
powered versions of the Alpha XL.
DO NOT CONNECT POWER AT THIS STAGE
Installation of the AL2-GSM Module/SIM Cards:
Read in conjunction with Contrive installation guide.
Unscrew the small cross head screw in the top right
corner and carefully slide the expansion cover to the
right to remove the module.
You will not be able to insert a SIM card with the gold
contacts facing down. The cutout of the SIM should be
near the edge of the expansion module.
As you refit the expansion cover you need to carefully
push the “flying” power connector onto the plug in the
base of the Alpha. Make sure this is seated correctly.
Please also ensure the antennae lead is placed within
the small aperture near to the crosshead screw. Now
slide the cover carefully from right to left ensuring no
cables are trapped and the left hand communications
connectors fits into its reciprocal.
Now connect the 24VDC supply to the Alpha ensuring
correct polarity is observed.
You can also connect a GSM Antenna to the flying FME
connector.
GSM Functions:
An example sample program is installed in the Alpha as
an overview of the various functions:
1.
Initialise Modem.
Link Function A01 needs to be activated to
switch the GSM Modem ON.This can be done
by triggering the block with an “Always On”
contact.
2.
GSM Network Registration
GSM Network Function Block is activated when
the AL2-GSM registers on the GSM Network.
(This can take up to 30 seconds)
3.
SeNd an SMS Message:
The GSMSMS Function block when triggered sends the
contents of the local display by SMS to the number
contained within the function block. This can be triggered
by any function of the Alpha (Inputs, Times, Compare,
Clock/Calendar, Incoming SMS, Incoming call etc….). This
gives total flexibility of when and what information to be
sent by SMS. It also allows you to embed “live” variables
into the messages as these can also be displayed on the
local display. (eg. Temperature, Analogue Values,
Counter, Hours Run, Set point Alarm etc…)

It can also be used to pass values into registers within the
Alpha . Eg set a counter threshold to 1000. (Send val=1000)
