……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 S101, S102 and S103 and the jumpers J102 to J106
on the NSK Unit (CMJ-431) 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-4111.
q Set the switches and jumper of the NSK Unit (CMJ-431) before turning on the radar equipment.
• S101:Set it to [OFF].
• S102: Set this switch assembly according to the particular type of gyro. Use the S102 Setting
table in Table 8.10 to set the switches.
S102-1 ........................Type [OFF] ....................... Synchro signal
[ON] ........................ Step signal
S102-2, -3...................Gyration ratio
S102-4 ........................Gyration direction [OFF] ................. Normal (clockwise)
[ON] .................. Reverse (counterclockwise)
S102-5 ........................Log type-1 [OFF] ................. Pulse signal
[ON] ................... Synchro signal
