3.4 GSM modem initialization
When ordering the treatment
plant, you can simultaneously
order an optional GSM modem.
At the startup stage, a SIM card is
installed in the GSM modem and a
mobile phone number for sending
the alarm messages is registered in
the operation settings.
NOTE! If the administration of the
treatment plant needs to be distrib-
uted to more than one GSM num-
ber, the numbers need to be report-
ed to the supplier when ordering.
Adding or removal of numbers later
on requires a soft ware update!
3.4.1 SIM card installation
Installing the SIM card does not re-
quire removing the screw-attached
front panel. The front wall of the
GSM modem is visible on the left
side of the control unit display. The
SIM card installation rail is opened
by pressing the open button.
3.5 Turning on treatment plant
Aft er the startup procedures are
completed, the treatment plant
main power is turned on. However,
the power is only connected once
treatable wastewater is fed into the
plant.
Once power is turned on, the treat-
ment plant moves into standby
mode, waiting for the accumula-
tion of the fi rst wastewater load to
be treated. In standby mode, the
compressor aerates the waste-
water. Once a certain amount of
wastewater has accumulated in the
process tank, the cleaning process
begins.
3.6 Sludge removal using a
vacuum truck
In the treatment plant, sludge is
removed by default using a sludge
bag.
If you want to change this and
remove sludge using a vacuum
truck, change the default setting
according to section 4.3.
3.7 Sludge removal using
sludge bags
See the sludge bag installation
instructions in section 5.3.1.
Install the SIM card as follows:
1.
Prepare the SIM card as in a
normal mobile phone: Remove
PIN code prompt. Remove all
existing messages.
2.
Shut down the treatment
plant.
3.
Open the SIM card installati-
on rail by pressing the open
button e.g. with a pen tip. The
attachment plate will come off
its rails.
4.
Insert the card so it clicks into
place.
5.
Lower the plate onto the rails
and push it into place.
6.
Connect main power.
The functionality of the modem
may be tested by sending “?” in
an SMS to the number of the SIM
card. The modem will reply with
the current process stage. If the
modem does not reply, repeat and
inspect the SIM card installation
stages.
3.4.2 Determining GSM number
A single number can be registered
in the GSM modem for the treat-
ment plant to send alarm mes-
sages to. The number is registered
through a soft ware menu. See
instructions for registering the
GSM number in section 4.3.
