User manual RAYMARINE OPEN ARRAY SCANNERS

[. . . ] Pathfinder Radar Scanners Owner's Handbook Document number: 81154_9 Date:September 2006 5 Pathfinder Radar Scanners Owners Handbook March 2004 Intended Use The scanner units detailed in this handbook form part of navigational radar systems intended for light marine use. These radar systems are only an aid to navigation. Safety Notices This radar equipment must be installed and operated in accordance with the instructions contained in this manual. Failure to do so can result in personal injury and/or navigational inaccuracies. The scanner unit contains high voltages. [. . . ] 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 maximum power cable extensions are given in the table below. These figures relate to the total cable extension, from the end of the supplied 1. 5 m power cable to the system battery terminals. Do not exceed these lengths as unreliable operation may result. cxcix Table 2-3: Max.

For example, using two pairs of 2 mm2 is equivalent to using two single 4. 0 mm2 cables. 24 V and 32 V systems These systems are less sensitive than 12 V systems to voltage loss in the power cables. However, it is still necessary to use adequate cables to prevent excessive power loss. The table below gives the recommended wire gauge for different power cable extension lengths. Raymarine recommends that power is fed directly from the output of the battery isolator switch via its own dedicated cable system.

If you are connecting an existing compatible scanner to a C-Series display a pedestal adaptor cable can be used instead of the split pedestal cable. CAUTION: Do not extend the split pedestal or pedestal adaptor cable. Split pedestal cable The split pedestal cable combines the inter-unit and power cores, divided by a Y junction. One core has a connector plug for connecting to the display unit, the other core is for connecting to power. The scanner end is prepared ready to fit to the power and signal connectors (see Section 2. 2). Two cable lengths are available: · 25m cable provides 25m from scanner to Y junction. [. . . ] Correction Check that the cable connecting the scanner to the radar display unit is firmly attached and undamaged. Check that the polarity of the cables is correct.
