FUNCTION

DN/UP Control

Supplies variable dc simulation signal, with a voltage range of -6.6 vdc to 6.6

vdc, through selected SIM of mode selector control, to specific amplifiers

selected. Simulation voltages, which are selected by mode selector control and

supplied through test set connector J1 to No. 1 stabilator amplifier, can be

monitored at NO. 1 SIM test point. Simulation voltages, which are selected by

mode selector control and supplied through test set connector J2 to No. 2 sta-

bilator amplifier, can be monitored at NO. 2 SIM test point. From 0 vdc refer-

ence, turning control DN supplies positive voltage output from test set, and

turning control UP supplies negative voltage output from test set.

Mode Selector Control

NORM supplies output signal from No. 1 and No. 2 collective stick position

sensors through test set connectors J1 and J2, to No. 1 and No. 2 stabilator

amplifiers, respectively. Signals from No. 1 collective stick position sensor can

be monitored at NO. 1 SNSR and NO. 1 SIM test points. Signals from No. 2

collective stick position sensor can be monitored at NO. 2 SNSR and NO. 2

SIM test points. GND supplies ground from test set through connectors J1 and

J2, to No. 1 and No. 2 stabilator amplifiers, respectively. These grounds can be

monitored by NO. 1 and NO. 2 SIM test points. SIM STAB 1 & 2 position

supplies variable dc simulation signal selected by DN/UP control through test

set connectors J1 and J2, to No. 1 and No. 2 stabilator amplifiers, respectively.

These simulation signals can be monitored at NO. 1 and NO. 2 SIM test

points. SIM STAB 1 supplies variable dc simulation signal selected by DN/UP

control through test set connector J1 to No. 1 stabilator amplifier. This simula-

tion signal can be monitored at NO. 1 SIM test point. This switch position also

supplies ground through test set connector J2 to No. 2 stabilator amplifier. This

ground can be monitored at NO. 2 SIM test point. SIM STAB 2 supplies vari-

able dc simulation signal selected by DN/UP control through test set connector

J2 to No. 2 stabilator amplifier. This simulation signal can be monitored at

NO. 2 SIM test point. This switch position also supplies ground through test

set connector J1 to No. 1 stabilator amplifier. This ground can be monitored at

NO. 1 SIM test point.

AS SENSOR Simulator

Provides capability for simulating or monitoring signal output from NO. 1

and/or NO. 2 airspeed sensors. Used for testing airspeed functions of No. 1

and No. 2 stabilator amplifiers.

NO. 1 SNSR Test Point

Provides monitoring capability for signal output of NO. 1 airspeed sensor.

When mode selector control is at NORM, NO. 1 SNSR test point is connected

to NO. 1 SIM test point.

NO. 1 SIM Test Point

Provides monitoring capability for No. 1 airspeed sensor simulation signal

when mode selector control is at SIM STAB 1 & 2 or SIM STAB 1. Provides

monitoring capability for 2.26 vdc (simulated signal output from airspeed sen-

sor from 0 to 30 knots of airspeed) supplied to No. 1 stabilator amplifier when

mode selector control is at SIM STAB 2. When mode selector control is at

NORM, NO. 1 SIM test point is connected to NO. 1 SNSR test point to pro-

vide monitoring capability for signal output of No. 1 airspeed sensor.
