184.108.40.206 To check if the ACR contacts will be damaged by continued ro-
tation, as set forth in 220.127.116.11.2:
18.104.22.168.1 Connect jumper between pins n-N of P201.
22.214.171.124.2 Apply voltages as set forth in 126.96.36.199.2 and 188.8.131.52.3.
The gyro shall cage as specified in 184.108.40.206.
220.127.116.11.3 Remove caging voltage from pins M-P of F201.
18.104.22.168.4 Manually rotate the gyro 360 degrees, as viewed from shove.
22.214.171.124.5 Repeat the tests set forth in 126.96.36.199 to ensure that no dam-
age resulted to the ACR contacts after the gyro was rotated as set forth
188.8.131.52 Remote setting system. To test the remote control setting
system as described in 3.3.6:
184.108.40.206.1 Mount the gyro on the calibrated gyro test stand (220.127.116.11.1)
with the flat base (NAVORD Drawing 859711) down.
18.104.22.168.2 Set the gyro test stand to zero degrees.
22.214.171.124.3 Connect the gyro to current Fire Control Systems or their
equivalent, as in Figure 3.
126.96.36.199.4 Cage the gyro according to instructions on the fire con-
188.8.131.52.5 Set the gyro dial on the fire control system to 90 degrees
port, and actuate the setting control until the indicating device (tuning
eye) shows the synchros to be aligned.
184.108.40.206.6 Place the ac vacuum tube voltmeter (220.127.116.11) across pins J-L
18.104.22.168.7 Uncage the gyro according to instructions on current Fire
22.214.171.124.8 Turn the gyro in a counterclockwise direction, as viewed
from above, until the voltmeter indicates null voltage (0.3 volt or less).
126.96.36.199.9 The time elapsed from the instant the gyro is uncaged
(188.8.131.52.7) until the gyro has been turned to its minimum voltage posi-
tion (null voltage 184.108.40.206.8) must be less than 30 seconds to prevent
the total gyro drift from affecting the test reading in 220.127.116.11.10 and
