function normally if a current sense fault exists. INHIBIT supplies ground
through test set connector J2 to No. 2 stabilator amplifier, preventing shutdown
of No. 2 stabilator automatic mode, should a current sense fault exist.
TEST position supplies 28 vdc to No. 1 pitch rate gyro to provide

TEST POINTS
Provide monitoring capability for functional conditions of stabilator system
operation. NO. 1 test points relate to No. 1 stabilator amplifier, and NO. 2 test
points relate to No. 2 stabilator amplifier.
NO. 1 and NO. 2 UP
Provide monitoring capability for No. 1 and No. 2 stabilator amplifiers scaling

drive in driver logic module turns on to command actuator. Each test point
voltage may be 15 vdc or 0 vdc.
NO. 1 and NO. 2 STAB
Provide monitoring capability for voltages supplied by No. 1 and No. 2 stabila-
UP and NO. 1 and NO. 2
tor amplifiers that will drive No. 1 and No. 2 stabilator actuators. When system
STAB DN Test Points
is in manual slew mode, test points have steady 28 vdc. When system is in
automatic mode, test points have 0 vdc to 28 vdc pulse with modulation.
NO. 1 and NO. 2 AUTO
Provide monitoring capability for 28 vdc engage voltage supplied by No. 1 and
ENGA Test Points
No. 2 stabilator amplifiers as soon as power is applied to helicopter, or when
stabilator is operated in automatic mode. NO. 1 and NO. 2 AUTO ENGA and
NO. 1 and NO. 2 AUTO ENGA OS indicators also go on.

amplifier that will be supplied back to drive amplifiers in No. 1 and No. 2 sta-
bilator amplifiers. 28 vdc is available at these test points as soon as power is
applied to helicopter or when stabilator is operated in automatic mode. NO. 1
and NO. 2 DRVR SPLY and NO. 1 and NO. 2 DRVR SPLY OS indicators
also go on.
