2. MOUNTING
The unit has a built-in GSM-modem. All types of SIM-
cards can be used except from 3G cards. However it is
recommended to use a SIM-card “Pay and go”
instead of an ordinary SIM-card because the latter
often has an expiry date after e.g. 6 months.
Prepare the central unit
1. Lift the front cover of the unit.
The unit must be turned off!
2. Connect all relay-outputs and inputs to the unit.
Use at least 24 AWG – or stronger if possible.
Install SIM-card
3. Insert the SIM-card to be used
into a GSM-mobile phone.
4. Check that the SIM-card’s PIN
code is set to 1234 (default for
most telephone companies). If not, set the PIN
code to 1234 or deactivate the PIN code.
5. Check if it is possible to call from the card, and
send/receive SMS.
6. Remove the SIM-card fromf the GSM-mobile
phone and insert it into the GSM-unit.
7. Check that any inputs and relay-
outputs are properly connected
and place the front cover onto
the central unit again.
8. Connect the central unit to 230 VAC or
12-24 V AC/DC. Wait approx. 10 sec. while the
GSM-modem makes contact to the GSM-network.
When you hear 4 ’beeps’ and the red LED lights
continuously for approx. 20 sec. the unit is ready.
9. Send, if necessary, a SMS with ”1234 OK” to
get the GSM signal strength. It must be higher
than 25%.
Electric mounting
The unit can be mounted on a DIN-rail.
1. If the GSM-conditions are bad, replace the
internal antenna by an external antenna.
2. Mount, if necessary, 9V rechargeable battery.
3. Connect outputs:
Relay-outputs are potential free relay contacts that
break (NO) or make (NC) by means of instructions to
the unit. As default all relay-outputs are open.
4. Connect digital inputs:
Digital inputs are optocouplers. The inputs are
activated by 0V default (gnd) or 24 VDC on inputs
(can be changed in the set-up program). If the
supply is removed the inputs will deactivate. In both
cases an alarm can be sent from the central unit.
NB! Input 0 can also be used for
activating/deactivating the unit (toggle switch or
bell switch). Input 1 can be used for counting pulses.
GND or 24V on inputs, selected as option in the PC-
software.
5. Connect analog inputs:
As default the analog inputs function as ordinary
digital inputs (all Dip - switches off). If the analog
inputs are to be adapted to standard equipment: 0-
10VDC, 0-20 mA or PT100 probe, the Dip-switches
in the GSM-modem must be adjusted as illustrated
below.
DIP switches for analog inputs
Digital: Dip-switch 1-4 off
0-10VDC: Dip-switch nr. 1 on
0-20mA: Dip switch nr. 2 on
PT100: Dip switch nr. 3 on
Profort probes: Dip switch nr. 4 on
Each analog input has 4 Dip-switches.
Equipment and probes must be connected
between gnd and Ain1.
