MODEL FEATURES AND OPTIONS
Always refer to supplied outline drawing for specific part number of this model type to determine the exact features. Outline drawings
for any Castleberry Instrument unit may be obtained via contact information on our web site: http://www.ciamfg.com
APPLICABILITY
Before installing the Model 300-14EL gyro, determine that it is appropriate for the application. This gyro comes either as a 14Volt,
28Volt, and 10-32Volt models. Select the part number that is right for the voltage of the aircraft (10-32Volt models may be used in
14Volt or 28Volt aircraft systems). The 300-14EL is designed for use in fixed wing or light helicopter aircraft with shock mounted
panels. It is not intended for use in acrobatic flying. This gyro can travel unrestricted 360 degrees through the roll axis but is limited
to ± 90 degrees of pitch travel.
This product conforms to FAA technical specifications TSO C4c. It is responsibility of the installer and their authority to determine
proper use, purpose, and documentation required to install this product. We do recommend that installers become familiar with FAA
advisory circular AC91-75 and special airworthiness information bulletins CE-05-15 and CE-05-41 since these documents relates to
purpose for recent applications of installing this product.
CONTINUED AIRWORTHINESS
There are no life limited parts or periodic scheduled maintenance requirements on this product to generate a need for continued
airworthiness procedures. It is recommended that the gyro be operated for 30 minutes minimum to redistribute lubricants if the gyro
has been unused for three months or longer.
OPTIONS
Panel tilt is an important specification required to be known when ordering or installing a panel mounted attitude gyro in an aircraft.
If panel tilt is not known, the manufacturer of the aircraft should be able to provide that information. This gyro can be calibrated for a
panel tilt from zero to fourteen degrees and should be specified when ordering. A label is attached to the gyro to indicate the tilt
calibration of each unit. If a newly installed attitude gyro settles more than ± 1½ degrees pitch above or below where the expected
horizon should be, then panel tilt or aircraft trimming issues should be suspected. Note that the gyro comes in a zero degree p/n or a
custom tilt p/n that should be selected when any tilt other than zero degrees is desired. Voltage type 14 or 28 or 10-32 Volt provides
other p/n variance.
LIGHTING
The 300-14E is an unlighted model. The 300-14EL is integrally lighted with externally selectable light tray. The unit comes with a
light tray of the same operating voltage as the gyro, however it may be replaced with other voltage types. Castleberry Instruments has
5, 14 and 28 Volt types available. For some models the wiring to lights is via flying leads that can be easily connected by installer’s
choice of connectors to the lighting buss and other models with internally wired lights through the rear connector. Lamps are of
incandescent type and may be operated by either AC or DC Voltages. The polarity does not matter. Check the outline drawing for
specific part number to see available lighting options.

ELECTRICAL
This model uses approximately 28 Watts starting and 17 Watts running. Therefore current rating for the 14 Volt model is 2 Amps
maximum and the 28 Volt model 1 Amp maximum. The 10-32 Volt unit uses 12 Watts nominal running. Power to gyro is applied
through a common 4 pin circular connector on rear of unit as shown on the drawings of following pages. Supplied with a new unit is
mating connector Castleberry P/N 8821-1032-0001 or cable 8824-1024-090(x) (either a -0901 for a 14V unit or -0902 for a 28V unit).
The industrial part number for the mating connector is MS3116F8-4S or PT06E8-4S(SR). Recommended wire size is 22 to 20 AWG
and should be of aircraft approved type. Circuit breaker or protection devices must be large enough to support the maximum current
for voltage type but small enough to protect aircraft wiring. We recommend a 1 AMP for 28 Volt systems and a 2 AMP for 14 Volt
systems. Note that pin out is different for the two different voltage models to prevent accidentally applying wrong voltage. Ground or
Negative is always to pin “A” and +14 Volts to pin “B” for the 14 Volt models and +28 Volts to pin “C” for the 28 Volt models. Due
to lighting variations, be sure to check outline drawing for specific part number to determine pin out for 10-32 Volt versions.
WARNING: Applying power to gyro reverse polarity or allowing a voltage spike exceeding 39 VDC will blow an internal
fuse to protect the gyro circuitry. If fuse becomes blown, unit must be repaired and tested before returning to
service.
CAUTION: This device is an avionics item and should get power from a buss that is not powered during engine start up.
MECHANICAL
Panel cut out and mounting hole information is shown in figure 1 and also supplied on outline drawing. This gyro is designed to be
installed rear mounted on a shock mounted panel. Be sure that installation screw length penetrates into gyro bezel approximately 1
inch after considering panel thickness including any shim or wedge application. Read all notes on following outline drawings to be
aware of any limitations or specifications that may apply to your installation requirements.
