Table 18: Indications of LEDs for the system status
After the button is depresses, the Control Unit Module Sigma LED displays a historical event stored in the
controller memory.
To distinguish that LED indications refer to past events instead of current status, the MEAS. indicator is
always off. Historical events stored in the controller memory include:
gas alarms, i.e. exceeding of the first or second warning thresholds or the alarm threshold,
non-critical or critical failure of the detector.
After 10 seconds the Control Unit Module Sigma LED quits presentation of historical events and returns to
display the current status.
When the button ‘Memory of events’ is depressed and held for more than 3 seconds the memory of events
is erased and the presentation of the current status on the front display is restored.
