Pump Cable; Solenoid Cable - Raymarine Autohelm 100 Install Manual

Chapter 2: Installation

Pump Cable

Cable Length
(Distribution Panel to
Pump)
Up to 3m (10ft)
Up to 7m (22ft)
Up to 16m (52ft)

Solenoid Cable

Solenoid Cable Length
(Course Computer to Pump)
Up to 7m (23ft)
Up to 12m (39ft)
Up to 17m (55ft)
An isolator switch should be installed in the power supply to the complete
system.
The solenoid valve connectors can only accept cable up to 12 AWG. If
larger cable is required, 18 inches of 12 AWG should be used to wire to
the connectors.
The Type CR Interface may also be connected to alternative constant
running hydraulic pump providing:
• the solenoid coils take less than 10 amps
• the response time of the solenoid valve is less than 80 milliseconds
• the operating voltage of the solenoid coils is the same as the course
computer supply voltage.
It is important to minimise the overall cable length between the pump and
the vessels power distribution panel.
