Any slack both on the coupling bar and the rudder sector must be eliminated
or this will falsify the measured rudder angle and the whole system will
become inaccurate and critical.
The excursion time of the rudder from hardover to hardover must be not less
than 12 seconds or more than 18 seconds, otherwise the system will be
instable.
This transducer must be linked to the Processor Box,
TB5 FEEDBACK
connector.
Electrohydraulic Unit
For a correct use of our autopilot and in order to obtain the best performance,
we suggest you to use hydraulic units suitable to the vessel steering system.
The flow-rate is the most important parameter when you choose a pump: it
must be calculated to obtain a hardover to hardover time of about 12 seconds
(±10/15%).
This is the formula to be used:
FLOW-RATE (liters/min) = RAM_VOLUME (liters) x 5
FLOW-RATE (cc/min.)
= RAM_VOLUME (cc.) x 5
When you use Ax or Crux Navicontrol.it pumps, you don’t need any
calculation: you must choose the pump with the nearest value to the ram
volume (i.e.: RAM = 100cc.
PUMP = R100 or CR100).
The CR pumps (constant running) can be installed on every kind of boat and
are mandatory for heavy or working vessels.
The R pumps (reversing) can be installed only on small pleasure vessels and,
in any case, no more than 15mt. (50 feet) length over all.
The electronics and the software provided with the autopilot are suitable to
drive the most popular 2 types of rudder activating:
Constant running (CR model with solenoid valves)
Software:
no setting (it is the default configuration).
