Software module 922 - TIC Vent valve
General Description
Set-up and monitoring of the TIC vent valve.
Output bytes (from Master)
None - No direct user control.
Input bytes (to Master)
No Alerts currently exist for these software modules so the 2nd and 3rd bytes will always be zero.
Associated Parameter options
1st
Indication of the Analogue output voltage as a number from 0
to 255. (0-10.34V). This voltage depends on the Master object
selected (see below).
2nd
Alert - refer to table in Appendix A2.
3rd
Priority - refer to table in Appendix A3.

Description of Parameter
1st
Module number
Cannot be changed.
2nd
3rd
Master object
Determines which object the analogue output represents.
Choices are: none; gauge1 signal; gauge2 signal; gauge3 signal
and turbo speed. If a gauge is selected the analogue output is
the same as the gauge voltage (regardless of gauge units). If
turbo speed is selected, 0
-
10V represents 0
-
100%.
