14401 Keil Road NE, Aurora, Oregon, USA 97002 PHONE 503-678-6545  FAX 503-678-6560  www.vansaircraft.com  info@vansaircraft.com Service Letters and Bulletins: www.vansaircraft.com/public/service.htm AFS Canopy Warning Read-Me 01/20/17 Although this read-me file is written in the context of the RV-14 it also is a starting point for application on other RV’s as well. A switch may be installed in the canopy latch system that is normally open when the canopy is open. When the canopy is closed and latched the switch should make a connection to ground. See the example circuit in Figure 1. The canopy warning .gca file enables the switch installed on RV-14 Page 38-32 to report through the EFIS when the canopy is not closed and latched. Above 1500 rpm if the canopy latch is is open (see caution statement below) both an audible warning and visual warning on the EFIS screen will be given. FIGURE 1: EXAMPLE CANOPY LATCH CIRCUIT NOTE: WH-00125 available from the downloads page of the Van’s Aircraft Web site may be a useful reference. Step 1: Install the WH-00126 Left Dash Mount Harness provided in the RV-14 Canopy Wiring Harness Kit. Step 2: Install a wire from the C414J 12 position Molex connector (that connects the canopy harness to the airframe harness) to “Input 1” on the PFD EFIS main connector. Note that warnings from the input pins are not shared between screens and therefore the wire must be connected to the Pilots primary flight display. See your AFS installation manual and or the AFS RV-14 Quick Panel Installation Manual for further
