Hydraulic Drive
Follow any instructions of the Hydraulic Steering supplier.
The AP9 Bosun autopilot can drive spool valves, relays or hydraulic
pumps. TMQ can supply the following pump units:
1.
A constant running pump set (including spool valves) for 24V DC
operation with flow rate up to 4000cc per minute.
2. A constant running pump set (including spool valves) for 240V AC
or 415V AC 3-phase operation with flow rate up to 5000cc per
minute.
3. Reversing pumps with adjustable (or fixed) flow rate to 1200cc per
minute (specify 12 or 24 volts).
Position
All pump units should be mounted horizontally, in a dry position , lower
than the highest Helm Pump on the vessel. Hydraulic lines must be used to
connect the pump to the steering lines of the vessel.
The balance line must be connected back to the helm reservoir.
Precautions
Some brands of Helm Pumps will require lock valves fitted to prevent the
helm from turning when the autopilot is operating. Consult your steering
supplier for this information.
All air must be purged from the steering system before commencing sea
trials with the autopilot. Consult your hydraulics manual.
