Power Pack Selection (Constant Running)
Hydraulic power pack selection depends on the
vessels overall length and the displacement of the
steering cylinder.
Using figure 2 establish the target hardover time
for your vessel. This is combined with the
steering cylinder displacement in figure 3 to select
the appropriate hydraulic power pack.
Note: If power packs other than the Autohelm
models are used with the ST7000 the following
solenoid specifications must comply-
Pull in Voltage - less than 8V (16v for 24v
systems)
Drop out Voltage - greater than 2V
Operating Current - less than 5A
The Solenoid Voltage must be the same as the
course computer.
