Record angular position of output arm. The maximum varia-
tion between the two recorded angular positions above
(backlash) shall be as specified in 3.3.5.2.
4.5.4.6 Output direction
4.5.4.6.1 With the actuator mounted as in 4.5.4.4.1, the
actuator adjustment set connected as in 4.5.4.4.2, and with
the pulley driven at 5000 to 6000 rpm in a cw direction (as
viewed facing the pulley), energize the aft coil (1 and 2 of
P40) with 7 plus or minus 2 ma. The output arm shall move
as specified in 3.3.6.1.
4.5.4.6.2 With the actuator mounted and driven as in
4.5.4.6.1, energize the forward coil (2 and 3 of P40) with
7 plus or minus 2 ma. The output arm shall move as speci-
fied in 3.3.6.2.
4.5.4.7 Output torque
4.5.4.7.1 Mount the actuator to the test stand (4.5.3.6)
with the torque gage connected to the actuator output arm
(the spring load is disconnected).
4.5.4.7.2 Connect the actuator adjustment set to connector
P40 (BUWEPS Drawing 694739), and drive the input pulley at
5000 to 6000 rpm in a cw direction, as viewed from the pulley
end.
4.5.4.7.3 Adjust the actuator adjustment set for "automatic"
variation of control current so as to alternately apply 12.5
plus or minus 0.5 ma to each clutch coil. There shall be
less than one ma in the other clutch coil. The measured
torque output from the actuator in either direction shall be
as specified in 3.3.8.1, to meet the requirement of 3.3.7.
4.5.4.8 Balanced current operation
4.5.4.8.1 With the actuator mounted and driven as speci-
fied in 4.5.4.7, adjust the actuator adjustment set so that
when the currents of both coils are within 0.25 ma of being
equal, the sum of the two currents shall be 11 plus or minus
2.5 ma. The torque shall not exceed the limits specified
in 3.3.8.2, to meet the requirements of 3.3.7.
