4.6.2.5 Erection Rate - During the erection rate measurement interval,
the displacement gyroscope shall be subjected to scorsby motion and
tested as follows:
a. Disconnect the roll axis servoed repeater and apply an
isolated; center-tapped, 11.8V, A voltage to connector 1J1-13, 1J1-14,
and 1J1-15 with the high side on 15 and the center tap on 14.
the jumper between

b.
connector 1J1-7 and 1J1-5.
c. Reverse pitch erection polarity by connecting 26V negative
C to connector 1J1-5. Remove this negative C voltage when the pitch
attitude becomes 10 1 and remove the isolated 11.8V A voltage
from connector 1J1-13,1J1-14, and 1J1-15.
Reapply pitch erection by reconnecting the jumper between
d.
connector 1J1-7 and 1J1-5, and begin timing when the pitch attitude
Note the pitch attitude at the end of 1 minute and
becomes 8.
compute the pitch erection rate by correcting for earth's rotation per
4.6.2.4a. The pitch erection rate shall be 40 to 60 per minute.
Reconnect the roll axis servoed repeater.
e.
Disconnect the pitch axis servoed repeater, and apply an
f.
isolated center taped 11.8V A voltage to connector 1J1-10, 1J1-11, and
1J1-12 with the high side on 12 and the center tap on 11.
Disconnect roll erection by removing the 6.5V C from
g.
connector 1J1-6.
Reverse roll erection polarity by connecting 26V negative
h.
C to connector 1J1-6. Remove this negative C voltage when the roll
attitude becomes 1O 1 and remove the isolated 11.8V A voltage from
connector 1J1-1O, 1J1-11, and 1J1-12.
i.
Reapply roll erection by reconnecting 6.5V C to connector
1J1-6 and begin timing when the roll attitude becomes 8. Note the
roll attitude at the end of 1 minute, and compute the roll erection rate
by correcting for the earth's rotation per 4.6.2.4b. the roll erection
rate shall be 0.75 to 1.75 per minute.
Reconnect the pitch axis servoed repeater.
