10 Apollo SL30 Installation Manual
3. The valid flag sensitivity shall be 125 mV ± 10% for the flag to leave the stop and 260
mV ± 10% maximum for flag to be fully concealed.
4. The To/From flag shall have an input impedance of 200 ohms ± 10% and a sensitivity
of ± 40 mV ± 15% at 25
o
C with flag fully in view.
5. The OBS resolver should be compatible with a standard 6-wire OBS interface:
H...........Reference output high
C...........Reference output low
D...........S1 COS input high
E ...........S3 COS input low
F ...........S4 SIN input high
G...........S2 SIN input low
Any electrical zero crossing will work because the SL30 will calibrate out any errors.
Glideslope Installation
Glideslope installation requires:
• SL30
• External non-numeric glideslope indicator that meets the following criteria:
1. The glideslope deviation shall have an input impedance of 1 k ohm ± 10% with a
deflection sensitivity of 150 mV ± 10% for full scale deflection.
2. The glideslope valid flag shall have an input impedance of 1 k ohm ± 10%.
3. The glideslope valid flag sensitivity shall be 125 mV ± 10% for the flag to leave the
stop, and 260 mV ± 10% maximum for flag to be fully concealed.
EQUIPMENT MOUNTING
Once the cable assemblies have been made, attach the 15- and 37-pin d-sub and coaxial cable
connectors to the rear connector mounting plate and the mounting frame as illustrated in
Figure 2 and Figure 3. Route the wiring bundle as appropriate. The rear connector plate should
be attached to the mounting frame before installing the frame in the instrument panel. The rear
connector plate can be used to tie down the cable assemblies. Use the supplied edge guard to
protect the cable from sharp edges. Connect the shield grounds directly to the connector
mounting plate.
Once the cable assemblies are complete and the connectors are attached to the mounting
frame, install the mounting frame assembly in the instrument panel. Be sure to use low-profile
head screws in the side of the mounting frame so the unit will slide in and out freely. Attach the
front of the mounting frame to the instrument panel. Use support brackets to attach the rear of
the frame to the aircraft.
To install the unit in the mounting frame, make sure the cam lock is rotated so the rear part is
up, then slide the unit into the frame and tighten (clockwise) with the 3/32 hex tool. The unit
will be pulled into the frame by the cam lock and the connectors will fully engage.
To remove the unit from the mounting frame, use the hex tool and turn the tool counter-
clockwise. The unit will be pushed out of the frame by the cam lock assembly. No special
extraction tools are required.
