Adjustment of NSK Unit to Gyro Compass and Log･･････････
The NSK Unit of the radar equipment is of solid-state type and designed to be compatible
with almost all types of gyro compass by switch operation (For the step motor type, 35 V
DC to 100 V DC, and for the synchro-motor type, the primary excitation voltage is 50 V AC
to 115 V AC). Before power-on operation, the switches S1, S2, S6 and S7 on the NSK
Unit (CMJ-462) shall be set to the type of gyro compass in use in accordance with the
procedures as described below. The gyro select switch on the NSK Unit is set to the
gyration ratio of 360X and to be compatible with the synchro type before delivery from
factory. Check the type of the gyro compass used in own ship and make settings in the
procedures below. For further details, refer to Fig. 127 Setting Table of Gyro Compass
and Gyro Select Switches of Display Unit, Type NCD-4263.
① Set the switches and jumper of the NSK Unit (CMJ-462) before tuning on the radar
equipment.
