Hanna Instruments PCA 310 - Manual (Page 59)

59
One or two phone numbers associated with the service - to
which the messages will be sent – must be set. The number
has to be entered in the fields named “No1” and “No2”. The
space reserved for a phone number is 15 digits.
The phone numbers have to be inserted using the interna-
tional format excluding the starting + character and without
any space inside the number.
Example: if the cellular number is +39123456789 (+39 is the country
code), the number to be stored in the PCA 310-330 is
39123456789.
The numbers could be activated or inactivated. The SMS is
sent only to active numbers. If both numbers are inactive, no
SMS is sent even if both numbers are correctly entered. To
activate the phone numbers, set “Active” in the “Phone1” and
“Phone2” fields.
The SMS sending has to be activated by selecting “Active” in
the “Send SMS” field. If “Send SMS” is set to “Inactive” then
no SMS will be sent even if the phone numbers are active.
The number of repeated alarm SMSs could be set in the field
“RepeatNo”. The range is between 0 and 5. If RepeatNo is set
to 0 than only one SMS is sent.
The delay between two repeated SMSs is set in the “Delay”
item. The range is between 5 and 60 minutes. If the “RepeatNo”
is 0, this parameter has no effect.
GSM CONNECTION
After the correct settings are done, the SMS feature can be
enabled by set “General Menu” - “Serial & GSM Comm.” -
“Type” to GSM.
Note: Power the GSM module before first attempt to connect the
analyzer to GSM network.
If the PIN number is wrong, then it is not possible to make the
cellular module connection. The “GSM Wrong PIN Code”
message is displayed.
Note: If the first attempt to initialize GSM engine fails because of a
wrong PIN, then no other attempt will be allowed (prevention
of sending three wrong PINs).
To make another attempt, a new PIN has to be entered and
the analyzer has to be restarted. The analyzer attempt to ini-
tialize the GSM module at startup.
