FlightDek D180 Rotax CHT

[BenUK]

Any suggestions for this please:?
I’m having problems with very high readings standard Rotax CHT senders ( 2 of and they are both new, I have the same issue with the old ones though, so it’s not the senders)

They are wired to GP1 & GP2 as per the manual. There is no other setting I can find to alter the sensors type. I’ve tried changing the Thermocoupler setting from K to J. Makes no difference.

I have tried to wire the on to the EGT/CHT harness. And they then give a more realistic ambient temperature, but they stay at ambient even though the EGT & oil temps are rising.

Any suggestions?
Thanks

The Rotax CHTs must be wired to the GP inputs, with a resistor an a 5V line connected in too. See page 3-15 in the D180 installation guide for the details on that.

Then you need to set the GP inputs to coolant temperature, and to sensor type 4. See page 6-16-17 for details on that.
