PROPULSION CONTROL SYSTEM
Start Up & Station Transfer:
1.
Ensure Compressed Air System is fully charged and in the automatic mode. See Air Compressor Operating
Instructions.
2.
Line-up Compressed Air System to feed the control air dryer and control air lines from the dryer to supply the
control air reservoir. For normal operation open air dryer inlet and outlet valves, close air dryer by-pass valve.
In case of air dryer malfunction close air dryer inlet and outlet valves, open air dryer by-pass valve.
3.
Energize control air dryer. (normal operation only)
4.
Ensure all control station throttles are in the center neutral position.
5.
Place the EOS command transfer valve in the EOS position. Control air pressure will be shown on the local
gage mounted on the EOS control console indicating that the local station has control.
6.
To transfer control from the local EOS station to any of the remote stations, place the command transfer switch
in the remote position and pull up on any of the remote station transfer switches until indication of control air
pressure is seen on the applicable remote control air pressure gage. At this time, all other command stations are
disabled. Transfer of command from the EOS to remote stations may only be initiated from the EOS and the
EOS station may regain control at any time by placing the command transfer switch back in the EOS position.
7.
To transfer command from one remote station to another, lift up on the station transfer switch at the desired
station until control air is indicated on the control air gage.
Main Engine Throttle Control:
1.
Ensure that engine throttles at the active station are in the neutral center position, or the start interlock feature
of the control system will prevent engines from starting.
2.
Start main engines. (See Main Engines Operating Instructions.)
3.
Position throttle levers from the center detent position to either the 20 degrees ahead or astern position for
clutch selection. Continued lever movement in the selected, clutch quadrant will increase engine speed.
4.
To change reduction gear ratio, main engine throttles at the active station must be in the center neutral position.
Bow Thruster Throttle Control:
1.
Ensure that bow thruster throttle lever controls (located at remote operating stations only) are in the neutral
center detent position.
2.
Start bow thruster engine. (See Bow Thruster Operation Instructions.)
3.
Position throttle levers from the center detent position to either the 20 degrees port or starboard position for
clutch selection. Continued lever movement in the selected clutch quadrant will increase engine speed.
