Under normal operation the detector continuously monitors the oil mist level in the engine.
The Control Panel communicates with each connected detector to obtain the measured oil mist level and
the detector status. The Control Panel determines if the measured oil mist level is above the alarm levels
or if there is a fault condition and activates the appropriate relays.
This information is also displayed on the Control Panel in graphical form on an LCD. A membrane keypad
allows the user to interact with the system.
3.1 SYSTEM POWER UP
On power up the system will perform a sequence of actions:
3.1.1 Detectors
The green power LED on each detector will be switched on indicating power is being supplied to the
detector.
3.1.2 Control Panel
Control Panel membrane will be switched on for a short period allowing a visual check
of their operation to be made.
Following this sequence, the Control Panel Power LED shall be on
The LCD shall show a bar graph for each engine indicating the average oil mist level and indicate that
the system is Normal.
Figure 74 Main Screen
Short lines to the right of each bar graph show the average alarm level for that engine.
3.1.3 Engine Overview
During normal operation the Control Panel will display the Main Screen, Figure 74, showing a bar graph
for each engine.
The name of the engine is shown below the bar graph.
The level displayed on the bar graph indicates the average oil mist level being measured on that engine
at that moment in time. The indicated level will change in real time as the oil mist level in the engine
changes.
3.2 ACCESS LEVELS
There are three access levels available, each allowing access to various options within the system.
3.2.1 User Level
At power up the system defaults to User level access, allowing access to view system information. No
changes can be made to the system configuration at User level.
