7.Attach instruction label (supplied) to shield cover for the INT and GYRO CON- VERTER boards.

8.Close the monitor.

9.Turn the power off and on again to reset the CPU.

Connection of external power supply

An external power supply is necessary when the repeater signal is step-by-step type and the step voltage is below 20 V or output voltage is less than 5 W.

1.Cut the jumper wire JP1 on the GYRO CONVERTER Board when an external power supply is used.

2.Connect the gyro cable and power cable as shown below.

DIP switch, jumper wire settings

Default setting

The default setting of all DIP switches is off and all jumpers wire are set to “#1.” (Note that the jumper wire JP1 is set at #1, #2, and #3.) In those settings the gyrocompass having the following characteristics can be directly connected; modi- fication of the GYRO CONVERTER Board is not necessary.

AC synchronous signal: 50/60 Hz

Rotor voltage: 60 V to 135 V AC

Stator voltage: 60 V to 135 V AC

Gear ratio: 360X

Supply voltage: 30 V to 135 V AC
