4.6.5.1 Test Connections - All control assembly components shall be
connected in accordance with figure 6 using the simulated magnetic
azimuth detector of 4.3.2.5. Connect a servoed repeater to the heading
outputs at electronic control amplifier connector (2J1), and to the roll
or pitch output at electronic control amplifier connector (2J4) as
required. Connect 400 Hz input power to the following pins of connector
1J1 on the electronic control amplifier:
Neutral
to
23
115V A
to
24
115V B
to
25
115V C
to
26
4.6.5.2 Special Test Conditions - Wait a minimum of 2 1/2 minutes after
application of power before conducting any test. controls for the
compass system controller and the electronic control amplifier shall be
set as follows except where otherwise noted:
Mode switch to DG
Latitude control to local latitude
Hemisphere switch to local hemisphere
Compensation switch to OFF
4.6.5.3 Test Procedures - Unsatisfactory results that occur in areas not
being tested at the time shall be investigated by performing the
If heading drift
applicable individual test on the component involved.
trim adjustment is performed, the heading drift rate test for the
displacement gyroscope shall be repeated- Azimuth rates greater than
6 per minute may cause removal of roll erection and slaving when
testing a control assembly that uses the ASK-32/A24G-39. Azimuth rates
greater than 24 per minute may cause removal of roll erection and
slaving when testing a control assembly that uses the ASK-44/A24G.
Sufficient time (up to 40 seconds maximum for the ASK-32/A24G-39 and up
to 16 seconds for the ASK-44/A24G) shall be allowed to permit the control
assembly to return to normal conditions after such rates cease. This may
be particularly noticeable when observing the sync indicator pointer on
the compass system controller.
4.6.5.3.1 Heading Rotational Polarity
DG Mode - The displacement gyroscope shall be rotated
4.6.5.3.1.1
The transmitted heading
through a right-turn heading change of 90.
signal from the electronic control amplifier shall increase by
approximately 90.
