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 dis-
plays - 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.
