DKG-329 User Manual V-12 (09.10.2012)
- 18 -
The GSM SMS sending is activated by setting the SMS Enable program parameter to 1.
When a fault condition occurs, the unit will compose an SMS message and will send it to up to 6
phone numbers. If modem is enabled, only 4 telephone numbers are available for SMS sending.
The unit is also able to send SMS messages in below conditions, without creating a visible alarm or
warning:
Mains Fail, Mains Restored (enabled via SMS on Mains Change program parameter)
If both modem and SMS are enabled, the unit will send SMS messages first and attempt modem
connection afterwards.
When SMS sending is in progress, an (SMS) icon will appear at the upper right corner of the
screen.
The maximum number of alarms transmitted in a SMS message is 4. This limitation is due to the
maximum length of an SMS message which is 160 characters.
A sample GSM SMS message is given below:
STOP : EMERGENCY STOP.
END OF ALARM LIST
The first line of the message carries information about the unit type and the site identity string. This
line is intended for the identification of the genset sending the SMS message.
Each following line will give one fault information. The message will always be terminated by the
“END OF ALARM LIST” string.
When the message is sent, the existing alarms will be masked, causing the audible alarm relay to
release and preventing consecutive GSM SMS messages. Any new upcoming alarm will result in a new
GSM SMS message. The new message will indicate all existing alarms, even masked ones.
The necessary GSM modem cable will be supplied by DATAKOM. This is the same cable as
PSTN (land) modems.
If Modem Enable or SMS Enable or MODBUS Address parameters
are different from zero, the local PC connection will not work.
