The KA 51 Slaving Accessory (PN 071-1053-00) is a panel mounted unit that displays the slaving
error between the KMT 112 and the KI 525 by means of a small meter movement.
The KA 51A/51B Slaving Accessory is an internally lighted panel mounted unit that displays the
slaving error between the KMT 112 and KI 525A by means of a small meter movement.
KA 51A, three pushbutton switches are provided below the slaving meter. The center switch is an
alternate action switch that engages the "slaved gyro" mode when depressed. When the switch
is in its outer position the KCS 55/55A is in the "free gyro" mode. The other two pushbutton switch-
es are momentary switches and provide clockwise and counterclockwise manual slaving whenev-
er the system is in the "free gyro" mode.
The KA 51/51A also contains circuitry through which hard-iron effects upon the KMT 112 can be
compensated by the adjustment of two potentiometers. Access holes labeled N/S and E/W are
provided on the front surface of the KA 51/51A for access to these two potentiometers.
The KA 51B, houses two toggle switches below the slaving meter. The switch nearest the meter
(SLAVE/FREE) is a lockout type toggle switch that engages the slaved gyro mode when in the
slave position and places the KCS 55A/KCS 305 in the free gyro mode when in the free position.
The lower switch (CW/CCW) is a momentary left and right toggle switch and provides clockwise
and counterclockwise manual slewing whenever the system is in the free gyro mode.
The KA 51B also contains circuitry through which hard iron effects upon the KMT 112 can be com-
pensated by the adjustment of two potentiometers. Access holes labeled N/S and E/W are pro-
vided on the side of the unit for access to the two potentiometers.
