EL-SMS-2G-TP / TP+ / PROBE-G USER MANUAL
Run Mode
Following a successful configuration of the unit it will enter into Run mode. In this
mode the unit checks to see whether any notification messages are due to be sent
(i.e. alarm breach, battery low or summary notifications) and then processes the
notifications in order of their priority:
●
Temperature alarms have the highest priority
●
Low battery alerts have medium priority
●
Summary messages have the lowest priority
In Run mode the temperature is measured once every minute using the external
probe and the value is checked to see whether either the upper or lower
temperature alarm limits have been breached. If an alarm limit is breached (see
alarm delay operation) the unit will send an alert notification message to the
contacts registered to receive the “alarm” group messages.
The battery condition is checked each time a temperature measurement is made.
If a low battery condition is detected a battery low notification message will be sent.
The buttons are disabled whenever the unit is actively sending an SMS.
Stop Monitoring
When the unit is in Run mode it can be put back into a Standby mode by pressing
the “Stop monitoring” button combination. This should be done whenever you want
to stop the unit from monitoring the temperature and sending alert messages.
To stop the unit, press the status button for five seconds whilst holding down the
“Stop” button for at least one second. The unit will show the green LED for three
seconds after which it will reset. The power up LED sequence will then be displayed

and the unit will be in the standby mode in an “unconfigured” state.
To start monitoring again you will need to repeat the setup process.
