BULLETIN MODEL 7 GYRO 9 57 1 1 of 6
Procedure: 24VDC INPUT POWER MODIFICATION FOR DELAYED SHUTDOWN
Description: Instructions for how to modify the 24VDC input power for delayed shutdown of Gyro Control J-Box
1. PURPOSE
This service bulletin describes how to install a time delay relay in the 24VDC input power to the Gyro
Control J-Box to delay the shutdown of power for 1.5 hours. This will allow the operator to initiate a
shutdown delay that runs the Gyro’s glycol cooling pump for 1.5 hours as the flywheel spools down
and then shuts off power to the Gyro Control J-Box.

3. INSTALLATION
Install the time delay relay in an appropriate enclosure. CABLE 1, 24VDC input power to the Gyro
Control J-Box, must route through this enclosure. Install the SPST switch in an accessible location,
typically the operator console. Connect these items in series with 24VDC input power according to the
schematic diagram below.

5. OPERATING SWITCH CONFIGURATION
The SPST operating switch for the Time Delay Relay should be mounted on the console near the
Keypad and Display or in a convenient location and labeled to inform the operator of the function. An
example is shown below with the two positions.

6. OPERATION, START-UP
Start-up of the Seakeeper Gyro is similar to normal start-up explained in the Seakeeper Operation
Manual, Doc 90021 Section 2.1, except the SPST operating switch for the Time Delay Relay must also
be turned ON.
The sequence is:
•Make sure AC and DC power are available.
•Turn “On” the boat’s AC and DC circuit breakers
that supply power to the Gyro.
oWhen 24 VDC is applied to the Time Delay
Relay the Green indicator turns “On”.
•Turn “On” the SPST operating switch for the
Time Delay Relay.
oWhen the Time Delay Relay energizes, the
Red indicator turns “On”.
•At this time the Gyro Control J-Box powers up
and the Display powers up.
•Turn “On” the boat’s pump that supplies seawater
to the Gyro heat exchanger.
•Verify that the “Lock” lamp is lit on the Gyro
Keypad.
•Proceed with normal Gyro operation as described
in the Operation Manual, Doc 90021.
Notes:
1. The Time Delay Relay does not need to be visible
nor monitored during normal startup and
shutdown.
2. The Time Delay Relay must remain connected to
a continuous source of 24 VDC.

7. OPERATION, SHUTDOWN
Shutdown of the Seakeeper Gyro is different from the normal shutdown explained in the Seakeeper
Operation Manual, Doc 90021 Section 2.6, because of the Time Delay Relay for extended operation of
the Glycol Cooling Pump.
The sequence is:
•Verify that no alarms are present on the Gyro
display.
•Depress Lock.
oKeypad SEA indicator turns “Off”.
oKeypad LOCK indicator turns “On”.
•Depress Run.
oKeypad RUN indicator turns “Off”.
oGyro speed (KRPM) decreases
•Turn “Off” the boat’s AC circuit breaker that
supplies power to the Gyro Motor Drive J-Box.
•Turn “Off” the SPST operating switch for the
Time Delay Relay.
oThis begins a delay off time of 1.5 hours.
During this time the Gyro Control J-Box,
Display, Keypad, and Glycol Cooling Pump
run normally.
oWhen the Time Delay Relay is counting
down the Red indicator flashes.
•Leave the boat’s DC circuit breaker that supplies
power to the Gyro Control J-Box “On”.
Notes:
1. The Time Delay Relay does not need to be visible
nor monitored during normal startup and
shutdown.
2. The Time Delay Relay must remain connected to
a continuous source of 24 VDC.
