SETUP INPUT
The LX 7007 PRO IGC has an input for an external speed command switch. Using the external switch it is possible to
switch between SC and Vario manually. Setting the
SC INPUT
to
ON
means that closing the switch will cause the
instrument to enter SC mode, and setting
SC INPUT
to
OFF
means that closing the switch will select Vario mode.
There is a third option by setting SC INPUT to
TASTER
and connecting a push button to the input, each key press will
toggle between SC and Vario.
An external alarm to supplement stall warning can be connected to the LX 7007 PRO IGC. The indicated airspeed at
and below which the which the alarm will operate is set under
STALL W:
. This is also useful in a glider that becomes
very 'draggy' at less than the optimum thermalling speed, such as the LS8. Setting
STALL W:
speed to coincide with
the onset of the drag bucket will enable optimum thermalling speed to be maintained.
The LX 7007 PRO IGC is supplied with an external temperature sensor. Selecting
TEMP. ON
will enable temperature
measurement by the sensor. Setting
TEMP. OFF
permits the user to enter the temperature reading.
There is another input called
VARIO PRIORITY.
When this input is activated by grounding the appropriate wire, the
unit will change over to Vario immediately. This input wire is set open (not grounded) as a factory default on delivery.
