Basic Functions
The GSM-Messenger is a remote monitoring system for tank filling levels (liter), meter readings and alarm
events. The device operates with an integrated GSM mobile phone module that registers itself on the respec-
tive mobile network.
The LINK input can be connected to 1-4 TECSON oil level indicators. Additionally the device monitors the two
event inputs A1 and A2 which are connected to a potential-free break or make contact (Relays / Reed).
In the event of an alarm or in appointed time intervals the GSM-Messenger automatically reports the current
plant status. Therefore the Messenger generates an SMS with a plant identifier (header), report reason, liter
inventory, meter readings and plant status. The data is sent to the parameterized destination phone number via
SMS. Under normal reception conditions the attached antenna is sufficient for the internal GSM radio module.
For bad reception areas an external mobile radio antenna with a 5m to 10m cable can be connected. Such an
outdoor antenna is available as an equipment accessory.
The GSM-Messenger indicates the device status via ist 4 LEDs (see page 6).
After a power or mobile network blackout the device automatically redials into the GSM mobile network.
Counting Functions
Since software version V3.xx the GSM-Messenger contains an integrated counter function.
For device versions V2.xx the special variant Messenger C+, 2+ or A+ was necessary for a counter function.
For these counter functions potential-free switching contacts are connected to input A1 or A2.
These are typically either reed contacts, relay outputs or make/break contacts.
Via inputs A1 and A2 the following counting functions are applicable
- Impulse counter (e.g. water meter with reed output)
- Event counter (counts how often the contact has been closed, i.e. how often an event has occurred)
- Operating hours counter (e.g. time counter that indicates how long a contact state persists)
The counting mode can be activated and parameterized via command #Ai=….
See enclosed description „Messages, Commands and Parameters for the GSM-Messenger“.
SIM Card
A prepaid or contract SIM card needs to be inserted into the GSM radio module.
This SIMcard has to be operative i.e. it has to be registered and activated.
After entering the PIN code at the device the GSM-Messenger automatically dials up into the respective mobile
network. When using a prepaid SIM card the prepaid credit needs to be recharged if empty. This can be done
e.g. via internet contractor or at an ATM.
OilView Connection
If the device is connected to the www.oilview.de system all device settings can be performed by the OilView
systems administrator/user. Only exception: The PIN entry is to be performed via the device keys.
If the OilView system is not desired the whole parameter settings as well as the device communication is to be
made per SMS via a mobile phone. The parameters will be transmitted and permanently saved to the device
via SMS commands #... . Accordinglyall reports generated by the device will be sent via SMS to the parame-
terized mobile phone numbers.

Electrical Installation
ØRecommendation:
Before starting the installation, check the mobile networks signal strength per mobile phone.
Normallythe reception via the internal GSM-Messenger antenna will be sufficient.
In case of a bad reception location (e.g. a deep basement) potentially mount and install the GSM-
Messenger in a higher located room.
In case of a bad reception strength an external mobile antenna might be necessary.
This can for instance be mounted in front of the basement window (equipment accessory, 5m cable)
ØMount the device at a spot of the wall that is secure against moisture and insolation.
The device is not suited for an installation in wet rooms or outside.
In such case of operation a protective housing with the respective suitability is necessary.
ØThe connection of a digital tank level indicator (e.g. LX-2, LX-2-R, Smartbox 1/2/3) is to be carried out per
signal line (e.g. 2 x 0.4 mm2). Several device outputs are connected in parallel.
ØThe counter and alarm inputs A1 and A2 (resp. A3) are to be connected with potential-free contacts.
Typical are reed contacts in case of counter inputs and relays in case of event inputs.
ØSIM card:
The SIMcard has to be registered and activated.
Before connecting it to the 230V supply voltage, check if the SIM card is inserted and engaged correctly
into the designated modem.
ØNetwork connection:
Remove the mains fuse, ensure safety (!).
Connect the power supply to the input clamps PE, N, L.
Alternatively a power plug cable can be used for the power socket..
ØPIN entry:
Activate the power supply and wait for ca. 30 seconds.
When all of the 4 LEDs shine the PIN code has to be entered once.
For the first PIN character press the left button n times, then press OK (right button).
Accordingly repeat the procedure for the other 3 Pin characters…
Example PIN: 3 1 0 2
Inputs: 3 x left button; 1 x left button; 0 x left button; 2x left button;
then OK. then OK. then OK. then OK.
8-digit PIN:
If the SIM card has an 8-digit PIN, then the card must be inserted into a smartphone and the PIN code
must be deactivated there. Only then insert SIM card into the GSM messenger.
Please note!
ØThe electrical connection and commissioning is only to be carried out by technical qualified personnel.
ØThe device is not suited for an external installation or the operation in wet rooms.
ØAttention! 230V supply voltage is accessible at the power input terminals - mortal danger!
ØFurther electronics are separated from the main voltage, potential-free and conducted in low voltage.
After entering the PIN code and potentially triggering the initial report via test button the device cover
needs to be closed.

Insertion of the SIM card
A SIM card (prepaid or contract) needs to be inserted into the GSM radio module.
IMPORTANT: The SIM card has to be registered and activated.
After the insertion of the SIM card the device requests to set the PIN code, see page 4.
The sending fees for the SMS reports will be invoiced to the cardholder.
’
RESET
’
:
In case
of a device error a software
reset possibly solves the error situation.
Therefore shortly press both buttons.
The adjusted parameters will remain unchanged.
’RESET+Clear’: The GSM-Messenger software can also be reset into the original delivery status.
Therefore press both buttons simultaneously and hold them for 5 sec.
During this process all registers and parameters will be reset.
Subsequently the PIN code of the SIM card needs to be reentered.
After the modem reconnection the tank reregistration (tank order) possibly needs
to be carried out again.
The commands #T and #H and all further commands need to be reset via SMS.

Error code GSM or modem:
Red LED flashes n times? This implies an ERROR:
1 x = Internal modem does not respond.
2 x = No SIM card detected inside the modem.
3 x = PIN invalid (PUK entry necessary, therefore insert
the SIM card into a mobile phone).
4 x = Credit is empty.
5 x = No / Bad reception (additional antenna?).
6 x = SIM card is not registered / activated.
7 x = Other modem error.
Registration was not successful, if necessary try to reset.
8 x = Interlock active!
In case of lots of failed network dial-up trials the device will
retry the dial-up only once a day. This mode operates for
255 days. By pushing the [Enter] button the device does
one logon trial to mobile network again. In case of success-
fully sending an SMS the interlock is removed.
9 x = No destination mobile number has been set up.
#T command has not been sent or OilView connection has
not yet been linked.
Device is not sending. Probably internal interlock is active!
1. Disconnect the power supply and switch in again.
2. Query device via smartphone: Send #r as SMS to the device
and wait for device replying (3 Min.).
3. Trigger 1 SMS sending by pushing the Test button in the device.
4. In error case check the SIM card with a smartphone.
Therefore send a SMS to the own mobile number.
