24 V and 32 V Systems - 10kW scanners

10 kW open array scanners can use any combination of inter-unit cable up to a maximum length of 35 m. However, these systems use considerable power and installations should be planned to minimize all cable lengths. Refer to the tables on page 1-19, Max. Extension Power Cable Lengths (m) - 10 kW Scanner.

Power cable

The open array scanner systems are intended for use on ships’ DC power systems operating in the following ranges:

4 kW	10.7 to 44 V DC range (that is, 12 V, 24 V and 32 V systems)
10 kW	20 to 44 V DC range (that is, 24 V and 32 V systems).

CAUTION:

10 kW open array scanner systems cannot be used directly with 12 V systems; they require a 12 V to 24 V converter rated to

180W. Contact your authorized Raytheon dealer or distributor for details.

Open array scanners draw considerable power from the vessels power source, especially in high wind speeds. It is essential for reliable operation that the unit is supplied with a low resistance power cable system, especially when operated from a 12 V power system.

CAUTION:

Do not use the open array scanner with an SL70 or Autohelm 7" LCD display unit. Failure to observe this may result in permanent damage to the display unit.

12 V systems (4 kW scanners only)

Extensions to the supplied power cable must be kept to a minimum and the power should be fed directly from the output of the battery isolator switch via its own dedicated cable system. It is recommended that no additional power switch is included in this power cable.

CAUTION:

The display unit does not include a fuse for scanner power, so an in-line fuse or circuit breaker MUST be included in the power cable.

All power connections must be of high quality to minimize their resistance and to remove the risk of accidental shorts. Recommended
