LDT-3003

Installation and Operation

Instructions

The LDT-3003 combines a clock, hour meter, voltmeter, and up to three temperature sensors in one housing. (Since the LDT-3003 is packed with different options, you may not have all three temp sensors.) It shows the temperature in either °F or °C, selectable by the user. This unit fits in a standard 2 1/8" (54 mm) hole used by most marine equipment manufacurers.

Mounting

The LDT-3003 mounts in any dash or flat panel that's at least 2 1/2" (64 mm) in diameter. To mount the unit, first make certain there is at least 3 3/4" (95 mm) from the dash. Also, be sure there is room to route the power and sensor cables. The

When you determine the location for the LDT-3003, drill a 2 1/8" (54 mm) hole in the dash. Slide the LDT-3003 through the hole from the front of the dash. Align it so that it's straight, then tighten the two screws with a phillips-head screwdriver.

Place the pushbuttons into the holes in the bezel and snap it on to the LDT-3003. The unit is now ready for wiring.

WIRING

Connect the wires as shown in the diagrams on the opposite page. The LDT-3003 operates from 10 to 15 vdc (12-volt system). You can connect the wires as shown in the diagram at the top of the page using only one accessory switch (not included), which switches the unit's lights on at the same time the unit is turned on, or you can wire the lights to a separate switch as shown at the bottom of the page. Regardless of which wiring method you use, the LDT-3003 must be wired to a 2-amp fuse! Failure to fuse this product will void the warranty and could result in damage to the unit or your boat.

The unit won't be harmed if the power wires are connected backwards, however, it won't work until they're properly connected.

Make certain to connect the green wire to unswitched +12 volts. This keeps power on to the unit's memory so that the clock will keep running even when the unit is switched off.

Find a location for the speaker that is protected from the elements, but still lets you hear it. The typical mounting location is behind the dash. If the LDT-3003's wires won't reach the speaker, splice ordinary speaker wire to them.

SENSORS

The LDT-3003 can use the following sensors:

TS-W2BK Two temperature sensors - Water and Temp 2.

TS-3BK One temperature sensor - Temp 3 only.

We reccommend you use the LDT-3003 with the above sensors in the following combination:

One TS-W2BK. This gives you two temperature displays - Water and T2.

or One TS-W2BK and one TS-3BK. This gives you three temperature displays - Water, T2, and T3.

For example, you can connect the TS-W2BK temperature sensors and mount the sensor labeled "water" on the transom to measure surface water temperature and the sensor labeled "T2" in the live well or on the hull for outside air temp. The TS-W3BK has an extra connector so you can attach the TS-2BK temperature sensor to it, then attach the TS-3BK's connect to the LDT-3003 and have three separate temperature displays.

The temperature sensors can be mounted in any convenient location. Use #8 stainless steel screws to attach the sensor to the hull. (Screws not included.) When mounting the water temperature sensor as shown above, make certain to place it on the transom where it will be in contact with the water at all times, if possible.

OPERATION Modes

The LDT-3003 has a clock,a clock alarm, up to three temperature displays, an alarm for each temperature sensor, an engine hour meter, and a voltmeter. To switch between these modes, simply press the mode key.

Clock

When the unit is turned on, the clock appears as shown at right. A dot in the upper left corner of the screen is for a.m. or p.m. - it's your choice when you set the clock. The clock will continue to run even when the unit is turned off.

MODE

Water Temperature

The first temperature to appear after pressing the MODE key is the water temperature. This sensor is mounted on the transom.

MODE

T2 Temperature

The second temperature to appear is T2. This sensor can be mounted in a live well, on the hull to measure outside air temperature, or just about any other location.
