Guardian Battery Pack Instruction Manual

CRE 55610R

Overview

Lithium Ion has become the predominant battery technology for hand held electronic
applications. In recent years due to its high energy density, high voltage, good cycle life
and excellent storage characteristics. This technical manual looks at the principles of
Lithium-Ion technology, its main advantages and disadvantages and how to charge and
discharge it efficiently and safely. This battery is designed exclusively for model train
operation.

2. Charging the Battery

 The charger has a female plug and on the Guardian board has a male plug.

Insert both plugs firmly to charge the battery. The charger will indicate a Red light
showing that the battery is charging.

 Charging time is 2.5Hrs to 3Hrs

 While the battery is charging the Blue light on the Guardian Board will flash.

 When the battery is fully charge the light on the charger will illuminate Green.

 On the battery Guardian Board the LED light will illuminate a solid Blue light

indicating the battery is fully charged and fully balanced.

 A full charge battery will provide an average of two (2) hours of running time,

depending on the type of locomotive and the length and nature of the train.

3. Installation

 It is necessary to have a way to control the locomotive while using battery

operation. It is recommended that Crest, On Board Receiver 2.4 Revolution
System CRE 57002SD or CRE57002SS, be utilized as the operating control. The
“On Board” receiver should be installed in the locomotive, tender or trailing car.

 Note: if you do not have the Revolution System to operate your locomotive you

need to purchase the complete set, CRE 57000SD or CRE57000SS.

 If the locomotive wired incorrectly for battery operation or there is a short on the

battery out-put wires on the locomotive the LED on the Guardian Board will
illuminate Red. Unplug the battery plug from the locomotive and wait for five
seconds for the Blue LED to Flash, at this time the battery is ready to use.

4. Operation

 Connect the Guardian male ‘two pin’ plug to the female ‘two pin’ plug on the

locomotive.

 Note: if the locomotive you are using does not have the female plug for battery

operation you need to wire the locomotive for battery operation. We recommend
using, ART 29511 plug for battery operation.

 Use the instruction manual of the Revolution Train Engineer 2.4 GHz to Link the

transmitter and receiver to operate the locomotive.

 The locomotive will stop moving when the battery reaches its discharge capacity.

The Guardian Board LED will Flash Red, at this time unplug the Guardian board
plug from the locomotive and charge the battery.

5. Discharging

 During discharge, the voltage of a charged Li-on cell will steadily drop from an

initial 4.2V once loaded. It is for this reason that a voltage sensing protection
circuit is fitted to prevent over discharge of any one cell.

6. Storage

 When the battery is not in use unplug the seven wire plug from the main

Guardian Board.

 The battery should be kept in storage in a clean, dry and ventilated area; it

should be avoided to touch with any corrosive substance and should be away
from excessive heat and open flames.

 Storage of cells between 32°F and 85°F is recommended although short periods

of storage (<24Hrs) at temperatures up to +85°F will not cause any long term
negative effects. Where possible, cells should be stored in an open circuit
condition in a dry environment close to room temperature. Li-on cells exhibit
excellent charge retention over a wide temperature range. When stored at room
temperature, a fully charged cell will only loose around 5% of its original capacity
in the first month and this loss will drop to around 3% for subsequent months.

7. Battery Cycle

 When charged and discharged cycles degrade the capacity of the battery.

8. LIMITED WARRANTY
