In case of malfunction the “System” LED will indicate any type of internal fault of
the unit. This LED is flashing green in normal conditions and is red in alarm
conditions.
Additional to the alarm LEDs each alarm circuit is equipped with a relay with
potential free switchover alarm contacts. These contacts can be used for external
processing of the signal or for control of further functions.
If a malfunction or failure of the power supply occurs, all three relays (both alarm
relays and the SYSTEMFAULT relay) will switch to alarm condition.
3.4 Electronic record
The OMD-2008 keeps an electronic record. The recorded data can be viewed at
the instrument at any time. Browsing the data does not interfere with the
measurement or instrument operation. Data is stored in excess of 18 Months.
