2.7.2 Remote installation
The Remote version, 050-023-0101, may be mounted on any convenient avionics shelf by securing with
screws, nuts or nutplates, (not included), in accordance with AC43.13-2A, §24.
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. Fail-
ure 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 air-
craft 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 accor-
dance 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.
