OMC-045-II
6.3 Operating
Mode
It is possible to optimize the currents from the OMC-045-II, through the “operating mode”. There are three
parts that can be optimized, these are: System, Sensor and Modem. These can be configured separately
to “Full power” mode or to “Low Power” mode.
The combinations are:

If one of the parts are set in “Low Power mode, the part will be disabled when it is not in use.
6.3.1 Operating Mode System Low Power
The system goes to sleep, if there are no tasks to perform.
6.3.2 Operating Mode System always on
If the system is configured in “Always on” mode, it will not go to sleep, even if there are no tasks to
perform.
6.3.3 Operating Mode Sensor always on
If the “Operating Mode Sensor” is set in “Always On”, the sensor will continuously get power, after the
system is powered. Except if an error occurs, the system will be shut down for 5 sec and powered back
on after the 5 sec.
6.3.4 Operating Mode Sensor Low Power
In “Low Power” mode, the system and sensors will only be powered if something has to be measured or if
the system needs to calculate or read the data. With this the required “Power Delay” is taken into
account.
6.3.5 Operating Mode Modem Always On
If the modem is configured for “Always On”, the modem is always on and is always externally reachable.
This option is used if the system is remotely controlled. It is possible to reconfigure the station with
firmware updates or for data collection
. In the OMC-045-II, the modem will be put in Slow Idle mode, to
preserve power.
6.3.6 Operating Mode Modem Low Power
The modem is powered down, if it isn’t used for tasks for 15 seconds.
