200-023-0001 Page 2-2 Rev. 9, Sept. 2013
2.4 Cable Harness Wiring
Referring to the appropriate Appendix, assemble a wiring harness as required for the installation. All
wires must be MIL-SPEC in accordance with current regulations. Two- and three-conductor shielded wire
must be used where indicated, and be MIL-C-27500 or equivalent specification. Proper stripping, shielding and soldering technique must be used at all times. It is imperative that correct wire be used.
Refer to FAA Advisory Circular 43.13-2A for more information. Failure to use correct techniques may
result in improper operation, electrical noise or unit failure. Damage caused by improper installation will
void the PS Engineering warranty.
2.4.1 Power
The MB10-Series are compatible with both 14 and 28 Volt DC systems. A 0.5 Amp circuit breaker is required for all installations. Power and ground wires should be #22 connected to J10 Pin 1. Connect airframe ground to J10 Pin 9only. No dropping resistors are required.
2.4.2 Audio Panel interface
The MB10 is designed to interface with standard aircraft avionics, and presents a 510 receiver impedance.
2.4.3 Lamp Dimming
The MB10 has manual dimming of the marker lamps, through the aircraft avionics dimmer. For 14 V
aircraft, connect J10 Pin 7 to the aircraft dimmer bus. For 28-volt systems, connect pin 8 to the aircraft
dimmer. If the dimmer input is not connected, or at zero VDC, the lamps will be on fully bright.
2.4.4 Marker Antenna Installation
A marker beacon antenna, appropriate to the type and speed of the aircraft, is required (not included).
Refer to aircraft and antenna manufacturer's installation instructions, as well as AC43.13-2A (or later
revision), Chapter 3, for information on proper antenna installation techniques. The marker beacon antenna must be mounted on the bottom of the aircraft.
2.4.5 External Marker Lights
For installations that require external marker beacon lights, there are three outputs that can drive 12-Volt
lamps only. The external output lamps are driven high (typically +9 VDC 1.5 VDC unloaded, at MAX
brightness) when active. Maximum source current per lamp is 125 mA. Voltage varies with dimming
bus.
Note: if a constant maximum intensity is desired for the panel- or remote-mounted MB10, connect pin 7
(14V) or 8 (28V) to aircraft power.
The MB10 is also has active-low, open-collector marker outputs (inner, middle, outer) for interfacing with
other avionics systems that might require an active-low output. If required, a pull-up resistor may be
placed on the active-low outputs. It should be >1k Ω, and may be pulled up to any voltage below 32V DC.
Note: It is possible to use BOTH outputs at the same time. For example, driving remote indicator lamps
and an electronic display.
2.4.6 Remote Mode Selector- MB10R version only
The MB10R has provisions for remote mounting the Marker Mode selector (Hi-/Lo-Test/Mute). This must
be an On-Off-Momentary On switch. Connect Pin 15 to ground to place the unit in High Sense, and momentarily ground Pin 13 to mute the marker audio. Holding this pin low for 1-second will test the lamp
circuits.

2.8 Post Installation Checkout
After wiring is complete, verify power is ONLY on pin 1 of J10 and airframe ground on J10 pin 9. Failure to do so will cause serious internal damage and void PS Engineering's warranty.
2.9 Operational Checkout
2.9.1 Required Test Equipment
In order to return an aircraft to service after installation of the MB10, the installer must have access to a
Marker Beacon signal generator:
a. IFR NAV401L, NAV402AP, IFR4000
b. TIC T-30D, T-36C
Equivalent test equipment is acceptable as long as the testing requirements can be met.
2.9.2 Marker Checkout
1. Connect a ramp generator at the antenna end of the marker coax. With the unit under test in HI sensi-
tivity, verify that a 160 V, modulated 95% with 1300 Hz, signal will illuminate the amber (M)
marker light, and that marker audio is present in the headphones when the Marker Audio is selected
on the aircraft audio system. Verify that the white (I) and blue (O) lights will illuminate within 3dB
of the amber lamp, with 3000 Hz and 400 Hz modulation is applied, respectively.
2. Repeat with the unit in LOW sensitivity, with 430 Volts applied.
3. Connect the marker antenna and verify proper operation.
2.10 Final Inspection
Verify that the wiring is bundled away from all controls and no part of the installation interferes with aircraft control operation. Move all controls through their full range while examining the installation to see
that no mechanical interference exists. Verify that the cables are secured to the aircraft structure in accordance with good practices, with adequate strain relief. Ensure that there are no kinks or sharp bends in the
cables and coaxial cables. Verify that the cables are not exposed to any sharp edges or rough surfaces, and
that all contact points are protected from abrasion.

Section III OPERATION
GENERAL INFORMATION
3.1 SCOPE
This section provides detailed operating instructions for the PS Engineering MB10, Marker Beacon system. Please read it carefully before using the MB10 so that you can take full advantage of its capabilities.
Figure 3-1 MB10 front panel
3.2 Power
Unit power is on whenever the avionics bus is energized.
3.3 Marker Beacon Operation
The Marker Beacon Receiver uses visual and audio indicators to alert you when the aircraft passes over a
75 MHz transmitter.
The Blue lamp, labeled “O”, is the Outer Marker lamp and has an associated 400-Hertz 'dash' tone. The
lamp and tone will be keyed at a rate of two tones/flashes per second when the aircraft is in the range of
the Outer Marker Beacon.
The Amber lamp, labeled “M”, is the Middle Marker lamp and is coupled with a 1300 Hertz tone. It is
keyed alternately with short 'dot' and long 'dash' bursts at 95 combinations per minute.
The White lamp, labeled “I”, is the Inner marker and has a 3000-Hertz 'dot' tone. The lamp and tone will
be keyed at a rate of six times per second.
The audio from the Marker Beacon Receiver can be heard by selecting the "MKR" push-button switch. To
adjust the volume level, there is a service adjustment located on the top of the unit.
A toggle switch is used to set the receiver sensitivity and to test the indicator lamps. Use "HI" sensitivity
initially. This allows you to hear the outer marker beacon about a mile out. Then switch into Low Sensitivity mode. “LO” sensitivity gives you a more accurate location of the Outer Marker. Holding the MKR
switch down for two seconds activates marker test lamp, labeled "T/M" and illuminates all three lamps
simultaneously to assure the lamps (internal and external) are in working order. TST does not activate
MM autopilot sense output. Releasing the button returns to the low sensitivity.
Pressing the marker mode select (to “T/M”) for two seconds will also cause the marker audio to mute for
that beacon. The next beacon received will re-activate the audio.
