Hi,

i would like to know if anyone of the CPD or P2 transmitter fails. we are not getting alarms or detection in the Mark-V. Is it possible to create an alarm or making rung so if anyone of the transmitter fails?

pls give me the suggestion and guide to make it.

I'm surprised you don't have anything to alarm on a CPD or P2 failure.
For P2 there normally is a Block L3GFLTV1 - Gas Fuel Control Fault, in there, there should be a P2 failure, usually (L3GFIVP) when P2 falls below LK3GFIVP usually set at -5 psi.

For CPD, there is usually a fault L3TFLTX when CPD is less than CAKCPD usually set at 70 psi.

The above is for a Frame 6, but should be roughly the same for any Frame size.
 
If your concern was failure of one of redundant transmitters, you should get a "high deviation" alarm when one transmitter differs from the other 2 by a significant amount. I don't remember what the settings are, but you can find them in the GE control specification.
