D-180 installed correctly?

[Steve_G]

Hi,

I installed the D-180 (no internal battery) with HS-34 and TT AP.  When I power up, the blue Dynon screen appears and all the lights on the HS-34 come on.  Then the main EFIS screen appears and the HS-34 lights go off and there is a clicking sound about every 8 seconds or so.  However everything else appears to work okay.  This is with the battery only - not ready for engine start yet.  This occurs with and without the 37 pin connector attached.  any ideas on what to check?  Thanks, Steve.

The clicking sound is normal if you have an internal battery - I think it has to do with the internal DC-DC voltage converter.

It may also be normal without the internal battery, as the same power controller doubtless powers the unit from the aircraft bus.

Steve,
Everything in your system sounds 100% normal, and you appear to have DSAB all wired up correctly.

The clicking is part of the auto calibration that occurs inside the EMS. It happens every 8 seconds anytime the unit is on. It only occurs in EMS units- the EMS-D10, EMS-D120, and the D180.
