These limits are designed to provide reasonable protection against harmful interference in a normal installation. [. . . ] For example, if you set the offset to the distance from the transducer to the surface, it will display the depth from the surface to the bottom of the water. Keel offset Water surface Depth of transducer Transducer Note: The boat illustrated uses a through hull transducer Keel offset Positive value Negative value A negative keel offset displays depth as measured from a point below the transducer. For example, if you set the offset to minus the distance from the transducer to the bottom of the keel, it will display the depth from the bottom of the keel to the bottom of the water. 3-1 Set depth units The units can be METERS, FEET or FATH: Press ;if necessary, press again. 3-2 Set too deep alarm The too deep alarm sounds if the alarm is turned on and the depth becomes equal to or more than the too deep alarm depth. To mute the alarm, press . To set the too deep alarm: 1 Hold for two seconds to display the Too Deep Alarm screen: or . 2 To change the alarm depth, press 3 To turn the alarm on or off, press . 4 Press . Deep alarm value Alarm is on Reference Manual and Installation Manual 7 3-3 Set too shallow alarm The too shallow alarm sounds if the alarm is turned on and the depth becomes equal to or less than the too shallow alarm depth. Depth data is output by the NS3100 DEPTH and can be read and displayed by the Northstar MULTI 3100 or other NMEA instrument. Reference Manual and Installation Manual 9 5 NS3100 DEPTH hardware 5-1 What comes with your NS3100 DEPTH The NS3100 DEPTH comes in several configurations. In addition, the standalone configuration usually requires a depth transducer (see section 5-3). Kit configuration The NS3100 DEPTH is available in several kit configurations with different grades of through hull transducer, with: The parts for the standalone configuration, listed above. The NS3100 DEPTH output is switched to ground, 30 V DC and 250 mA maximum. For systems of several instruments, wiring and connectors are required (see section 4 or the NavBus Installation and Operation manual). Never install a bronze transducer in a metal hull, because it will cause electrolytic corrosion. A range of Northstar through hull transducers are available, plus in hull and transom mount transducers. For more information, refer to the Transducer Installation manual or consult your Northstar dealer. 5-2 Other parts required One or more NS3100 series instruments will be connected to the boat 12 V power supply via: An accessory switch to turn the instruments on and off. Use a 1 A fuse for between one and five instruments. 5-3 Transducer The NS3100 DEPTH is usually used with a through hull depth transducer. However, the unit can take readings from another instrument, in which case it may not need a transducer (see section 4). A through hull transducer generally gives the best performance and is the best choice for displacement hulls. Plastic through hull transducers are not suitable for solid wooden hulls (use Northstar's bronze transducers). 5-4 Accessories These accessories are available from your Northstar dealer. 4 m (13 ft) depth transducer extension cable NavBus junction box (See section 4) 10 Northstar NS3100 DEPTH 6 Installation and setup Correct installation is critical to the performance of the unit. It is vital to read this section of the manual and the documentation that comes with the other parts before starting installation. for alarms, units, calibration and backlighting are The NS3100 DEPTH can: shared (see section 4-1). Send and receive NMEA data from other Send and receive data from other Northstar instruments (see section 4-2). Protect the rear of the unit from water, or else water might enter the breathing hole and damage the unit. The warranty does not cover damage caused by moisture or water entering the back of the unit. [. . . ] Repairs to the unit must only be carried out by a service centre approved by Northstar. More information can be found on our Website: www. NorthstarNav. com 1 Unit will not turn on: a Fuse blown or circuit breaker tripped. 2 Depth reading wrong or erratic: a Unit temporarily unable to detect bottom, for example water too deep or too shallow, water not clear, boat reversing and transducer in turbulent water. d Depth transducer installed incorrectly or transducer does not have a smooth flow of clear water over it.
