When starting the engine, the >OIL< Icon is illuminated. This can last up to approx.
15 seconds after starting the engine. This is not a warning, but shows, that the engine
has not yet reached the operation oil pressure. As soon as the normal operating oil
pressure is reached, the icon extinguishes.
If the >OIL< icon together with the red alarm light start flashing during
flight and an alarm is sounded through the Intercom, the oil pressure is too
LOW!
5.8.2 Analogue Oil Pressure Sender
If an analogue oil pressure sender is used, the
ALPHA
ALPHA
ALPHA
ALPHA
MFD
indicates the exact oil
pressure in bar (or PSI). The value is displayed in the right hand corner of the display
in the following formats:
Example:
5:7 represents an oil pressure of 5,7 bar
10:3 represents an oil pressure of 10,3 bar
25 represents an oil pressure of 25 PSI
56 represents an oil pressure of 56 PSI
The oil pressure is displayed with 3 digits and a resolution of 0.2 bar (or 2 PSI). The oil
pressure unit can be set in SET-Mode 26, bar or PSI is possible.
The
ALPHA
ALPHA
ALPHA
ALPHA
MFD
is designed to be used with the VDO Oil Pressure sender. It
will not indicate correct values with other types of oil pressure senders.
The
ALPHA
ALPHA
ALPHA
ALPHA
MFD
monitors the minimum and maximum permissible oil pressure
values. They can be set in SET-Mode 13 and 14. If the values are exceeded, the
>OIL< icon and the oil pressure display start to flash and an alarm is sounded through
the Intercom. If the oil pressure display is not activated at the time of the alarm (e.g.
the flight time is displayed instead), the oil pressure display automatically shows up.
The oil pressure display can be activated by pressing the >
ENTER/MEMO
< key, the
display is designated by the >OIL< icon.
If the engine is started, the oil pressure display is automatically activated and the oil
pressure is shown for approx. 15 seconds. If the engine reaches the normal operating
oil pressure range (defined by the minimum and maximum values in SET-Mode 13 and
14) during those 15 seconds, the display switches back to the previously selected
display (e.g. flight time).
If during flight the oil pressure drops below the minimum oil pressure or
exceeds the maximum oil pressure, the >OIL< icon and the oil pressure
display and the red alarm light start to flash and an alarm is sounded
through the Intercom. If the oil pressure display is not activated at the time
of the alarm (e.g. the flight time is displayed instead), the oil pressure
display automatically shows up.
