28 Apollo SL30 Installation Manual
LIMITATIONS ON USING A COMPOSITE SIGNAL
If an external converter is driven from the composite output in conjunction with a full function
CDI/HSI with resolver, the indicator head type, when selected from the Setup Mode during
the post installation checkout, should be RESOLVER. In this installation, the composite output
will be disabled whenever the VOR monitor mode is active or back course localizer mode is
enabled. This will cause the external converter to flag. If the CONVERTER option is selected
from the Setup Mode as the indicator head type, neither of these two options is available to the
pilot and the composite output should always be valid. The CONVERTER setup option should
be used if an external converter is the only indicator interfaced to the SL30.
POST INSTALLATION CHECKOUT
Once the unit is installed, complete the checkout procedure to verify proper operation. Refer
to the User’s Guide for operating instructions.
The steps that are not applicable to a particular installation may be skipped. A checkout log
sheet is included on page 34 to fill out during the checkout procedure. Make a photocopy of
the log sheet for ease of use if desired.
MOUNTING / WIRING CHECK
Verify that all cables are properly secured and shields are connected to the rear of the
mounting frame. Check the movement of the aircraft controls to verify that there is no
interference.
SETUP AND CHECKOUT
The SL30 has a built-in I/O test mode to simplify system setup and checkout. To operate the
SL30 in the Setup Mode, hold down the ó and SYS buttons while switching on the power.
You must continue to hold the buttons in until a complete power up is done and SELECT CDI is
displayed. To return to normal operation, switch the power off, and then back on.
In the Setup Mode, turn the large knob to view each function. In general, press the SEL button
to activate selection, turn the small knob to view each option, and then press ENT to save the
displayed value. Pressing SEL again will exit the option without saving any changes.
