Labkotec D04222BE-5 Communication Unit Instruction Manual
OVERVIEW
The Labcom 220 communication unit is designed for the monitoring of
industrial, domestic, and environmental engineering measurements remotely.
Typical applications include oil separator alarms, tank sur- face level
measurements, as well as pumping station and property monitoring
Labcom 220 sends alarm and measurement data in text messages ei- ther directly
to the users’ mobile phones or to the LabkoNet® server via GPRS connection to
be stored and shared with other parties
You can modify the unit settings with your mobile phone whenever necessary.
You can also specify when measurement results are to be sent and to which
mobile numbers. You can also query the results using a text message.
Alarms are triggered if the specified alarm thresholds (upper or lower) are
reached, or if the state of a digital input changes.
This installation and user guide contains instructions for the installa- tion,
commissioning, and use of the communication unit.
Labcom 220 and mobile phones
The figure below illustrates the message exchange between users and the Labcom
220 communication unit. All messages are sent as text messages. These are
detailed later on in this document.
You can store two types of mobile numbers in the unit:
End user numbers to which measurement and alarm messages are sent. These mobile numbers can also be used to query meas- urement
Administrator numbers can be used to change the unit No measurement or alarm messages are sent to these mobile numbers, but they can be used for sending measurement queries.
NOTE! If you want to use the same mobile phone for receiving meas- urement and
alarm messages and for specifying unit settings, you must specify the
applicable mobile number both as an end user and an administrator number.
Labcom 220 and LabkoNet®
Labcom 220 can be connected to an online LabkoNet® monitoring system. Using
the LabkoNet® system alongside mobile phones brings various advantages,
including constant connection monitoring as well as measurement and alarm data
storing and visual presentation.
Alarm and measurement data from measurement points is transferred to the
LabkoNet® server through the communication unit over the GSM network. The
server stores the data into a database from which it can later be accessed for
reporting purposes, for example.
The server also checks the data of each measurement channel that is sent by
the unit, converts it into the applicable format, and checks for possible
alarm threshold violations. If it detects any violations, it sends the alarm
data to the predefined email addresses as email messages and mobile numbers as
text messages.
End users can also view measurement data in numerical or graphical format on a
standard Internet browser online at
www.labkonet.com with their user credentials.\
INSTALLATION AND COMMISSIONING

The Labcom 220 unit enclosure is wall-mounted.
Open the cover of the enclosure
Drive the upper screw into the wall, hang the enclosure on it, and then drive
the lower screw into the wall.
Make the required connections according to the instructions in Chapter 2.2.
Install the SIM card into the unit according to the instructions in Chapter 2.2.
Close the cover of the enclosure.

Digital input 1
Mains input, 230 VAC
Fuse 125 mAT
Connecting the unit to the mains supply
The operating voltage of the unit is 230 V, 50/60 Hz. The maximum connected
load is 4 VA.
Connect the voltage to the terminals marked L and N (see the figure above).
Use a dedicated feed from the distribution board, if possible. The unit is
equipped with a 125 mAT distribution fuse (5×20 mm, glass tube).
NOTE! An isolating switch (250 VAC/1 A), which isolates both termi- nals (L1,
N), must be installed to the supply voltage line near the unit to make use and
maintenance easier. The switch must be labelled as the unit’s isolating
switch. A standard plug can be used as the isola- tion switch.
Connecting the sensors
The Labcom 220 unit is equipped with two 4…20 mA analogue inputs.
The unit provides a supply voltage of about 24 VDC (+Us) for a pas- sive
2-wire transmitter (pass. 2W) or 3-wire transmitter (3W). Alternatively, you
can connect an active 2-wire transmitter that obtains its power supply from
some other system to the analogue input.
Connecting the digital inputs
The Labcom 220 unit has two digital current sinking inputs (switch in- puts).
These are powered by a 20…28 VDC supply voltage, provided by the unit. The
current is limited to about 200 mA. All digital and ana- logue inputs share
the same voltage source and current limit
Cabling
To ensure sufficient protection against interference, you should use screened
instrumentation cables and, for analogue inputs, double- sheathed cables.
Install the unit as far as possible from units with relay controls and other
cabling. Input cables should not be routed closer than 20 cm to other cabling.
Keep the input and relay cabling separate from the measurement and
communications cabling.
Use single point earthing, if possible.
Installing the SIM card
Labcom 220 can be used with a SIM card of all the common 2G/3G operators.
Install the SIM card acquired for the Labcom 220 communication unit to your own mobile phone and check that you can use it to send and receive text messages.
Disable the PIN code query from the SIM card using your mobile
Open the Labcom 220 SIM card holder by sliding the cover of the holder to right and then lifting the cover up. Install the SIM card with its metal contacts facing down and lock the card in place by sliding the cover of the holder to
Commissioning
All Labcom 220 commissioning procedures are carried out using text messages.
You can use the following order, for example:
Specify the end user mobile numbers (TEL).
Alarms and scheduled measurement messages are sent to these numbers. They can
also be used to query the unit status (‘M’ que- ry).
Specify the administrator mobile numbers (OPTEL).
Once you have specified the administrator mobile numbers, you can only modify
unit settings from one of these numbers. If no administrator mobile numbers
have been specified, you can modi- fy the unit settings from any number.
Specify a name for the unit (NAME).
The name is displayed at the start of every message sent by the unit.
Specify the parameters for the measurements and digital inputs (AI and DI messages).
Specify common (ALTXT) and measurement-specific alarm mes- sages (AIALTXT).
You may also find the following settings useful:
Specify the transmission time for scheduled measurement mes- sages (TXD).
Specify the time (CLOCK).
The following chapter contains more details on the above-mentioned settings.
It also covers all other unit settings.

MESSAGES AND REPLIES
Mobile numbers
Adding mobile numbers for end users and administrators
The ‘End user and administrator mobile numbers’ setup message con- tains the
following fields, separated by a white space:
Field
Description
TEL or OPTEL
TEL = ‘End user mobile numbers’ message identifier
OPTEL = ‘Administrator mobile numbers’ message identifier
| The mobile number in international format
You can send all numbers accepted by the unit in one message (provid- ed that
the standard message length of 160 characters is not exceeded).
You can specify up to ten (10) end user mobile numbers. You can specify up to
five (5) administrator mobile numbers.
The unit saves the numbers in the first available memory slots in the order it
receives them. If the message contains more than ten numbers or if no memory
slots are free, the unit does not save the excess phone numbers.
The following sample message
TEL. +35840111111 +35840222222 +35840333333
adds three end user mobile numbers to the unit. The unit sends the following
reply (with one previously saved end user mobile number in the memory):
TEL. 1:+3584099999 2:+35840111111
3:+35840222222 4:+35840333333
The unit’s reply message format is as follows:
TEL :
The message lists memory slot/number pairs for all end user mobile numbers
stored in the memory.
To query the end user mobile numbers stored in the unit, send the fol- lowing
message:
TEL.
To query the administrator mobile numbers stored in the unit, send the
following message:
OPTEL
Deleting end user and administrator mobile numbers
Use the ‘Delete end user and administrator mobile numbers’ message to remove
mobile numbers from the unit. The message contains the following fields,
separated by a white space.
Field
Description
DELTEL or DELOPTEL
