SECTION IVTHEORY OF OPERATION
4.0 GENERALThe KNI 416 converts the Analog Altitude (Auxiliary Output #1) from the KRA 405/ KRA 405B Re-ceiver/ Transmitter to a visible indication of the aircraft altitude. The indicator consists of a fixed dial and servoed motor driven pointer.A Decision Height (DH) annunciator provides the pilot with a visual alarm when the selected DH is reached. The DH lamp may be turned off after it has come on by depressing the lamp once or turned back on by depressing the lamp a second time. The control logic ensures that the DH lamp will light when the aircraft descends through the decision height.The DH lamp is also photocell controlled so that the lamp does not blind the pilot during the critical stage of an approach if low ambient light conditions exist.Refer to FIGURE 4-1 KRA 405 System Block Diagram and the appropriate KNI 416 schematics. Refer to KRA 405 Maintenance Manual p/n 006-05104-00XX for radar altimeter system theory.The KNI 416 consists of the following major functions.
1. Servoed Pointer2. Decision Height (DH)3. Push-to-Test4. Failure Warning Flag
4.1 SERVOED POINTERThe servo-mechanism positions the pointer to the correct altitude by balancing the Analog Altitude (Auxiliary Output #1) and the voltage developed across precision reference R102 which is posi-tioned by the servoed motor. The input analog altitude is buffered by I301A, I301B, and Q301. Circuit I301B and Q301 provide a reference ground used to isolate the analog altitude from the indicator chassis ground.Circuit I204A and Q209 make up a Slope Amplifier that provides the 0 to 200 foot expanded scale.At altitudes below 200 feet (+4.4 volts) I204A acts as a non-inverting amplifier with a gain of 8.5. When the altitude reaches 200 feet (+4.4 volts) Q209 turns on reducing the gain to 1.6. R257 ad-justs the breakpoint in order to achieve optimum accuracy.The servo amplifier drive network, I210B, Q203, and Q204 differentially compares the analog al-titude to the reference voltage at TP209 determined by the position of R102.If the two voltages are unequal, a voltage is applied to the motor B101 that repositions R102 at a zero error position. The pointer then indicates an altitude corresponding to the analog altitude volt-age input to the indicator. Transistors Q203 and Q204 provide current drive to the motor. A float-ing voltage reference Q102, Q103, CR208, and CR209 is provided at the negative side of the mo-tor.This reference always maintains the negative terminal of the motor at one half the 27 volt filtered line (this voltage is unregulated and will vary from 21 to 32 volts), so that the positive and negative drive voltages to the motor will always be symmetrical. Transistors Q102 and Q103 provide a cur-rent sink for the motor.

B KNI 416
4.2 DECISION HEIGHT (DH)The Decision Height preselected by the DH knob is the height at which the pilot must decide whether to land or not. When the DH is reached, the DH annunciator comes on, alerting the pilot of the predetermined altitude. The capability exists for the DH to be turned off after it lights by depressing the lens once or turned on again by depressing it a second time.Any time the DH bug is at an altitude lower than the aircraft altitude during descent, the light will come on as the aircraft descends through the DH. If the DH bug is set to greater than 50 feet, the self test function will turn the light on.I210A compares the buffered analog altitude to the voltage proportional to DH altitude set by R101. When the voltage at TP218 is less than the voltage at TP204, the output of the DH com-parator goes high, causing the DH light to turn on through inverters I202A and I202B.The lamp logic I202 and I203 is used to turn the lamp off once it has been turned on. When the DH button DS101B is depressed, the flip-flop I203A changes state, disabling I202B thus turning off Q201, the relay driver, extinguishing the DH lamp. Circuits I202C and I202D comprise a one-shot multivibrator used to debounce DS101B.The pulse output at TP205 is approximately 90 milliseconds. The DH Lamp can be turned on again by pressing the DH Lamp a second time, then the flip-flop changes state, returning control of Q201 to the DH comparator. The DH circuitry automatically rearms itself if the aircraft should ascend through the DH or if the DH bug should be reset below aircraft altitude.In either case, when the voltage at TP204 goes low, indicating the aircraft is above the DH setting, a logic 1 is applied to the reset input of I203A through CR207, causing the flip-flop to produce a logic 0 at the Q output returning control of Q201 to the DH comparator.The intensity of the DH lamp is controlled by the DH lamp dimmer, V101 and Q104. The resis-tance of photocell V101 is determined by ambient light conditions. The more ambient light avail-able, the smaller the resistance of V101 becomes, providing more voltage to DS101A through Q104 causing the lamp to be brighter. Similarly, the lamp is at minimum brightness in low ambient light conditions.The ground for the DH lamp is provided through a set of relay contacts of K201. Another set of contacts are provided so that external DH annunciate circuitry can be utilized.
4.3 SELF TESTThe self-test button functionally tests nearly the entire KRA 405 system, and initiates a complete self test for the KRA 405B. The calibration loop information is transferred to the signal loop for normal processing and displayed as if it were a true altitude. Self-test forces the failure warning systems, including the indicator flag. It also tests the DH if the DH bug is set greater than 50 feet, and provides a 50 foot altitude indication to the pilot. When the self-test button S101 is pushed the following occurs:
a. A ground is provided to initiate KRA 405/ KRA 405B self test circuits.b. Q208 is turned on, resetting flip-flop I203A.c. Q101 is turned on through CR213, placing the failure warning flag in view.

B KNI 416
4.4 FAILURE WARNING FLAGThe failure warning indicator to the pilot is a bright red flag which alerts the pilot to possible fail-ures. Monitored inputs to the flag control circuit are as follows:
a. Servo ErrorThe servo error voltage output by I201B is monitored by the servo error detector I205A and I205B. Should the error exceed +/- 5 volts at TP212, indicating a servo malfunction, the voltage at TP213 goes high, turning off Q207.When Q207 turns off C204 discharges through R247, R248, and Q101 turning the relay drive Q101 off within 0.5 seconds after the servo error is detected bringing the flag DS107 into view.
b. +27.5 Vdc Aircraft PowerWhen aircraft power is lost, the flag comes into view since no power is available to drive DS107.
c. Self TestWhen the self test button is depressed, Q101 is turned off through CR213, causing the flag to come into view.
d. +30 VdcIf +30 Vdc power is lost, drive to Q101 is lost causing the flag to come into view.

5.2 TEST AND TROUBLESHOOTINGThis section provides guidelines to locate faults to the sub-assembly and component level. Use troubleshooting procedures as necessary, when a unit fails to meet the performance require-ments of the functional test procedure.Troubleshooting procedures for the KNI 416 differ slightly from align procedures. After trouble-shooting procedures have been completed, the unit should be calibrated and aligned by proce-dures outlined in paragraph 5.3 CALIBRATION AND ALIGNMENT.Alignment procedures are to be used after misalignment has been isolated by the use of the trou-bleshooting flow charts, and/or other troubleshooting techniques, and to adjust levels to customer specifications.
CAUTION:THIS EQUIPMENT CONTAINS ELECTRO-STATIC DISCHARGE SENSITIVE (ESDS)COMPONENTS. EQUIPMENT ASSEMBLIESAND ESDS COMPONENTS MUST BE HAN-DLED IN ACCORDANCE WITH SPECIALESDS HANDLING PROCEDURES.
Contained within this section are troubleshooting flow charts, troubleshooting sequence charts, and detailed troubleshooting procedures.Prior to any tests, the units should be checked visually for foreign objects, broken wires, loose screws, broken or blistered components.It is assumed the unit passed previous performance tests prior to the current failure.For troubleshooting purposes remove the dust cover and connect the equipment as directed in the appropriate test set-up using the KRA 405 or KRA 405B. It is not necessary to disassemble the radio unless noted otherwise.The sequence of troubleshooting follows the troubleshooting flow chart of FIGURE 5-5 Trouble-shooting Flow Chart.The flow chart and troubleshooting procedures assume that signals under test are checked on the signal terminating board, or continuity is checked from the signal source board to the signal termi-nating board.When a circuit board is suspected of a failure, all power supply voltages and signal inputs, as well as continuity of signal output paths to terminating boards, must be checked before replacing the board.The correct troubleshooting procedure is determined by the type of failure in the functional test procedure. Technicians should use traditional troubleshooting methods to isolate to the assembly and component level. Schematic diagrams and theory of operation are provided to assist trouble-shooting to the component level. After repair and reinsertion of any assembly, the KNI 416 should be checked again for any other faults. When all the assemblies have been repaired and reinserted, the functional test should be performed to assure that the KNI 416 is again operating satisfactorily.
5.2.1 KNI 416 TEST SET-UP AND TESTING (USING KRA 405)
A simulated Analog Altitude voltage is required to test the KNI 416 indicators. This signal is pro-duced by driving the KRA 405 R/T Precision Outputs to the correct voltage with the test IF signal. The test signal should be applied through the two audio attenuators to TP201 of the KRA 405 R/T as required.
Revision 4, February/2006 15661M04 Page 5-7
B KNI 416
Unless noted otherwise, set the audio attenuators to 0 dB.Test set-up is shown in FIGURE 5-1 Test Set-Up (Using KRA 405). All tests using the KRA 405 R/T are performed with the 40 foot AID selected (Pins a and j of P4051 jumpered).Initially the 27.5 Vdc input to the KRA 405 and KNI 416 should be adjusted to 22.5 ± 0.5 Vdc.The RFI Filter assembly may be removed according to procedures in paragraph 5.6.1.1 RFI Filter Assembly to further expose the Servo Amplifier Board Assembly.The sequence of test and troubleshooting follows the troubleshooting flow chart FIGURE 5-5 Troubleshooting Flow Chart.

5.2.2 KNI 416 TEST SET-UP AND TESTING (USING KRA 405B)
In addition to the required dc voltages supplied by the KRA 405B, a simulated Analog Altitude volt-age is required to test the KNI 416 indicators. This signal is produced by driving the KRA 405B R/T Precision Outputs to the correct voltage using the P405B1-m; Alt_Test_Input. The Alt_Test_Enable_1 and Alt_Test_Enable_2 lines must be grounded to enable the P405B1-m; Alt_Test_Input. The scale factor for P405B1-m; Alt_Test_Input is +10 mV / foot. A 0 to 25Vdc input = a 0 to 2500 foot analog output.
NOTE:The KRA 405B with software version -0101 requiresan RF signal with loop attenuation 6 dB greater thanlockup to provide a threshold signal for the uproces-sor at any altitude between 0 and 2500 feet. Soft-ware versions greater than -0101 do not have thisconstraint.
NOTE:When using the Alt_Test_Input the length of the an-tenna cables must be taken into consideration. Theelectrical length of the total antenna coax in feetmust be added to the variable power supply voltage.For example: If the RT was zeroed and the calibra-tion included 30 electrical feet of coax and round-tripRF path to ground, and simulation of 50 feet altitudeis desired, the variable power supply is set to 0.5V +0.3V for a total of 0.8Vdc which equals the desired50 feet + the 30 feet of antenna coax and round-tripRF path to ground.
If the RF path length used for calibration is not known, then adjust the power supply until the Analog_Altitude Hi voltage is 0.400Vdc. This power supply voltage becomes the offset voltage required at each altitude to compensate for the RF path length.Test hook-up is shown in FIGURE 5-2 Test Set-Up (Using KRA 405B).Initially the 27.5Vdc input to the KRA 405B and KNI 416 should be adjusted to 22.5 ±0.5VdcThe RFI Filter assembly may be removed according to procedures in paragraph 5.6.1.1 RFI Filter Assembly to further expose the Servo Amplifier Board Assembly.

5.3.2 CALIBRATION AND ALIGNMENT (USING KRA 405B)
Calibration and alignment must proceed in the order listed below to minimize interference between various adjustments. An operational KRA 405B must available before starting this section.
1. Servo Pot Zero2. Servo Calibration 3. DH Pot Zero4. DH Pot Calibration5. KNI 416 Performance Test
A simulated Analog Altitude Voltage is required to test the KNI 416 indicator. This signal is pro-duced by driving the KRA 405B Altitude_Test_Input with a dc voltage while Altitude_Test_Enable_1 and Altitude_Test_Enable_2 lines are grounded. This dc voltage will vary from 0 to 25Vdc which represents 0 to 2500 feet altitude.
NOTE:KRA 405B software version -0101 requires an RFsignal with loop attenuation 6 dB greater than lockupto provide a threshold signal for the uprocessor atany altitude between 0 and 2500 feet. Software ver-sions greater than -0101 do not have this constraint.
NOTE:When using the Alt_Test_Input the length of the an-tenna cables must be taken into consideration. Theelectrical length of the total antenna coax in feetmust be added to the variable power supply voltage.For example: If the RT was zeroed and the calibra-tion included 30 electrical feet of coax and round-tripRF path to ground, and simulation of 50 feet altitudeis desired, the variable power supply is set to 0.5V +0.3V for a total of 0.8Vdc which equals the desired50 feet + the 30 feet of antenna coax and round-tripRF path to ground.
If the RF path length used for calibration is not known, then adjust the power supply until the Analog_Altitude Hi voltage is 0.400Vdc. This power supply voltage becomes the offset voltage required at each altitude to compensate for the RF path length.See TABLE 5-2 Precision Outputs vs. Altitude and Signal Loop for a list of Precision Outputs vs. Altitude vs. IF frequency.Test set-up is shown in FIGURE 5-2 Test Set-Up (Using KRA 405B).Initially the 27.5 Vdc input to the KRA 405B and KNI 416 should be adjusted to 22.5 ± 0.5 Vdc.It is recommended that all measurements on switching waveforms, comparator outputs and sim-ilar voltages be monitored with an oscilloscope so that the oscillations and abnormal waveforms may be detected.Precision voltage measurements should be made with an accurate digital voltmeter.

5.5.3 REPAIR
A. GeneralThis section contains information required to perform limited repairs on the unit. The repair or replacement of damaged parts in airborne electronic equipment usu-ally involves standard service techniques. In most cases, examination of drawings and equipment reveals several approaches to perform a repair. However, certain repairs demand following an exact repair sequence to ensure proper operation of the equipment. After correcting a malfunction in any section of the unit, it is recom-mended that a repetition of the functional test of the unit be performed.
B. Repair Precautions1. Ensure that all ESDS and MOS handling precautions are followed.2. Perform repairs and replace components with power disconnected from
equipment.3. Use a conductive table top for repairs and connect table to ground conduc-
tors of 60Hz and 400Hz power lines.4. Replace connectors, coaxial cables, shield conductors, and twisted pairs
only with identical items.5. Reference “component side” of a printed circuit board in this manual means
the side on which components are located; “solder side” refers to the other side. The standard references are as follows: nearside is the component side; farside is the solder side; on surface mount boards with components on both sides, the nearside is the side that has the J#### and P#### con-nector numbers.
6. When repairing circuits, carefully observe lead dress and component orien-tation. Keep leads as short as possible and observe correct repair tech-niques.
Revision 4, February/2006 15661M04 Page 5-37
B KNI 416
7. There are certain soldering considerations with surface mount compo-nents. The soldering iron tip should not touch the ceramic component body. The iron should be applied only to the termination-solder filet.
8. Observe cable routing throughout instrument assembly, prior to disassem-bly, to enable a proper reinstallation of cabling during reassembly proce-dures.
CAUTIONTHIS EQUIPMENT CONTAINS ELECTRO-STATIC DISCHARGE SENSITIVE (ESDS) DE-VICES. EQUIPMENT MODULES AND ESDSDEVICES MUST BE HANDLED IN ACCOR-DANCE WITH SPECIAL ESDS HANDLINGPROCEDURES.
C. Electrostatic Sensitive Devices (ESDS) Protection1. Always discharge static before handling devices by touching something
that is grounded.2. Use a wrist strap grounded through a 1MΩ resistor.3. Do not slide anything on the bench. Pick it up and set it down instead.4. Keep all parts in protective cartons until ready to insert into the board.5. Never touch the device leads or the circuit paths during assembly.6. Use a grounded tip, low wattage soldering station.7. Keep the humidity in the work environment as high as feasibly possible.8. Use grounded mats on the work station unless table tops are made of ap-
proved antistatic material.9. Do not use synthetic carpet on the floor of the shop. If a shop is carpeted,
ensure that a grounded mat is placed at each workstation.10. Keep common plastics out of the work area.
D. MOS Device ProtectionMOS (Metal Oxide Semiconductor) devices are used in this equipment. While the attributes of MOS type devices are many, characteristics make them susceptible to damage by electrostatic or high voltage charges. Therefore, special precautions must be taken during repair procedures to prevent damaging the device. The fol-lowing precautions are recommended for MOS circuits, and are especially impor-tant in low humidity or dry conditions.1. Store and transport all MOS devices in conductive material so that all ex-
posed leads are shorted together. Do not insert MOS devices into conven-tional plastic “snow” or plastic trays used for storing and transporting stan-dard semiconductor devices.
2. Ground working surfaces on workbench to protect the MOS devices.3. Wear cotton gloves or a conductive wrist strap in series with a 200KΩ re-
sistor connected to ground.4. Do not wear nylon clothing while handling MOS devices.
Revision 4, February/2006 15661M04 Page 5-38
B KNI 416
5. Do not insert or remove MOS devices with power applied. Check all power supplies to be used for testing MOS devices. and be sure that there are no voltage transients present.
6. When straightening MOS leads, provide ground straps for the apparatus for the device.
7. Ground the soldering iron when soldering a device.8. When possible, handle all MOS devices by package or case, and not by
leads. Prior to touching the device, touch an electrical ground to displace any accumulated static charge. The package and substrate may be elec-trically common. If so, an electrical discharge to the case would cause the same damage as touching the leads.
9. Clamping or holding fixtures used during repair should be grounded, as should the circuit board, during repair.
10. Devices should be inserted into the printed circuit boards such that leads on the back side do not contact any material other than the printed circuit board (in particular, do not use any plastic foam as a backing).
11. Devices should be soldered as soon as possible after assembly. All solder-ing irons must be grounded.
12. Boards should not be handled in the area around devices, but rather by board edges.
13. Assembled boards must not be placed in conventional, home-type, plastic bags. Paper bags or antistatic bags should be used.
14. Before removing devices from conductive portion of the device carrier, make certain conductive portion of carrier is brought in contact with well grounded table top.
E. PC Board, Two-Lead Component Removal (Resistors, Capacitors, Diodes, etc.)1. Heat one lead from component side of board until solder flows, and lift one
lead from board; repeat for other lead and remove component (note orien-tation).
2. Melt solder in each hole, and using a desoldering tool, remove solder from each hole.
3. Dress and form leads of replacement component; insert leads into correct holes.
4. Insert replacement component observing correct orientation.
F. PC Board, Multi-Lead Component Removal (IC’s, etc.)1. Remove component by clipping each lead along both sides. Clip off leads
as close to component as possible. Discard component.2. Heat hole from solder side and remove clipped lead from each hole.3. Melt solder in each hole, and using a desoldering tool, remove solder from
each hole.4. Insert replacement component observing correct orientation.5. Solder component in place from farside of board. Avoid solder runs. No sol-
der is required on contacts where no traces exist.

B KNI 416
G. Replacement of Power Transistors1. Unsolder leads and remove attaching hardware. Remove transistor and
hard-coat insulator.2. Apply Thermal Joint Compound Type 120 (Wakefield Engineering, Inc.) to
the mounting surface of the replacement transistor.3. Reinstall the transistor insulator and the power transistor using hardware
removed in step (1).4. After installing the replacement transistor, but before making any electrical
connections, measure the resistance between the case of the transistor and the chassis, to ensure that the insulation is effective. The resistance measured should be greater than 10MΩ.
5. Reconnect leads to transistor and solder in place.
H. Replacement of Printed Circuit Board Protective Coating
WARNINGCONFORMAL COATING CONTAINS TOXICVAPORS! USE ONLY WITH ADEQUATE VEN-TILATION.
1. Clean repaired area of printed circuit board per instructions in section 5.5.2 CLEANING of this manual.
2. Apply Conformal Coating, Humiseal #1B-31 HYSOL PC20-35M-01 (Hu-miseal Division, Columbia Chase Corp., 24-60 Brooklyn Queens Express-way West, Woodside, N.Y., 11377) P/N 016-01040-0000.
3. Shake container well before using.4. Spray or brush surfaces with smooth, even strikes. If spraying, hold nozzle
10-15 inches from work surface.5. Cure time is ten minutes at room temperature.
I. Programmable Read Only Memory (PROM) ReplacementThe read only memory packages are specially programmed devices to provide specific logic outputs required for operation in the unit. The manufacturer’s part (type) number is for the un-programmed device, and cannot be used. The Honey-well part number must be used to obtain the correctly programmed device.
