Introduction....
The Whelen LiFe model LF28 portable scene light features a Lithium
Iron Phosphate (LiFePO
4
) battery. This type of battery provides efficient
and long-lasting energy using the safest, most environmentally friendly
technology available. In addition, Lithium Iron Phosphate batteries are
capable of up to 5 times as many charge cycles as traditional Lithium
Ion (LiCoO2) batteries!
For maximum battery life, there are precautions that must be followed
to ensure long battery life. Be sure to follow the information contained in
this manual carefully.
Installation
1.
Select a mounting location for the IIC (Intelligent Inductive
Charger) base. The base may be mounted on any smooth, flat
surface of ambient temperature. This surface can be either
horizontal or vertical (provided the base is properly oriented).
IMPORTANT! The location selected must not allow the LF28
to be exposed to temperatures above 140°F or below -4°F.
This will cause permanent damage to the battery and void the
warranty.
2.
Position the base against the proposed mounting surface. When
determining the location for the base, remember there needs to be
sufficient room for the LF28 to be easily removed from and
returned to the base for charging (see below). Additionally, the
Release Button/Diagnostic Display needs to be clearly and readily
visible.
3.
With the base in position, mark the locations of the four mounting
holes with an awl, marker or similar tool. Remove the base from
the mounting location and using a 1/4 inch bit, drill 4 mounting
holes. Be sure to deburr these holes before continuing.
4.
Return the base to its mounting location and using the hardware
provided, secure the base to its mounting surface.
Wiring
DC chargers -
Using appropriately sized wire, extend the wires coming
from the base to an ignition controlled, 12VDC circuit capable of
accommodating a current draw of 5 amps. The circuit used should be
fused at 7.5 Amps.
IMPORTANT! Failure to use an ignition
controlled circuit could, over time, result in vehicle battery drain.
AC Chargers -
AC chargers (120/240 VAC) do not require any special
wiring. The base features an AC adapter and includes a removable
power cord that plugs into a standard AC receptacle.
Operation
After installation of the charging base has been completed, mount the
LF28 onto the base. Orient the LF28 so that the light is facing away
from the release button/diagnostic display. Place the LF28 onto the
base so that the four, metal, mounting tabs are located just ahead of the
mounting tab retainers. Slide the LF28 backwards until it fully engages
the mounting release button with a ‘click’.
Once the LF28 is latched into position, the IIC will evaluate the battery
state and report its condition by illuminating the Release Button in one
of four colors. Each color represents a different property of the battery
and serves to keep the user informed as to the battery’s state:
RED -
Indicates that the LF28 is properly positioned and the battery
is charging.
GREEN -
Indicates that the battery has been fully charged.
Note:
This
color may remain lit for a few moments after the LF28 has
been removed from the charger.
AMBER - Indicates that the temperature of the LF28 is outside its
acceptable range (140° to -4°F). The user must
immediately move the light into an area within the
acceptable operating range.
BLUE -
Alerts the user that a metal object has been placed on or
near the charger and should be removed. After removal,
wait for the Blue light to go out before placing the LF28
in the charger. This may take up to 30 seconds. Do not
place any object other than the LF28 on the charger!
While the LF28 is on its base, the battery is being constantly monitored
and charged as needed. The translucent release button doubles as the
diagnostic display and provides important information about the state of
the battery.
Note that the LF28 can not be activated while on the
base.
