9. EDM-960 Key Card Installation
The EDM Key Card activates the primary engine instrument limits for you engine monitor. This key card contains the
primary engine POH markings data. After installation do not remove the Key Card from the instrument. The key card is
programmed with the serial number of your EDM and the make, model and year of your aircraft. Every time you power
up the EDM, the Remote Auxiliary Display (RAD) will show your aircraft make and model in the right engine RAD. The
Left RAD will display “EDM-960”
Each system is configured to a specific aircraft type. Therefore for example, a Cessna 310R would have a different
series Part number than a Cessna 310Q.
Installation
With the EDM removed from the aircraft, position it on a flat surface with the rear of the instrument facing you as
shown below. You do not have to remove any cables if you have sufficient service loop available. Follow the
appropriate instructions below.
Open the small access door on the side of the
EDM-930/960 Display using the appropriate tool.
KEY
CARD
UP
Hold the Key Card so that the UP arrow is facing
up and in insertion arrow is facing to the right.
Insert the Key Card in the guide rails until you feel it snap into place. Secure the access door.
Power up the EDM and confirm that your aircraft make and model is initially shown in the RAD upon power up. Install
the EDM back into the aircraft. Your installation of the Key Card is complete.
If your EDM should ever have to be replaced with a unit with a different serial number, the factory will reprogram your
Key Card to match the new serial number. You should always retain your fuel quantity calibration records, as these
may need to be manually re-entered in a different or serviced unit.
