Keep this manual within easy reach for the user of this battery charger
Hydrogen gas will be produced when charging lead-acid batteries and hydrogen gas is explosive.
Open flames and sparks should be kept away from batteries they may produce explosions.
The charger should be switched off before the charger/battery plug is disconnected.
General
The Smart charger Charger is suitable both for Freely Ventilated- (Wet) and Valve Regulated- (Dry) lead/acid
batteries.
The charger is small and very compact and can therefore easily be fitted close to the battery.
The charger operates in high frequency and should be connected to a standard 230V mains connection with
ground. The built in micro controller controls the charging process according to the chosen charging algorithm.
During charging the charging progress is displayed with status indicator LED on the front panel. The micro-
controller is also controlling the charging progress with regards to temperature in the charger and time. If a
fault occurs in some cells or the temperature rises the charging current will be limited. If you have a special
requirement of charging algorithm or application, please contact CME.
Installation
The Smart charger Charger is suited for indoor and outdoor use.
It can be used positioned horizontally on a table or a shelf, hang on a wall or as a built-in charger in the vehicle
or machinery.
The charger can be with fixed connection to the battery or with conventional connectors.
Position the charger in such a way that the air supply will not be obstructed.
When the charger is fitted on a wall or mounted in a vehicle it should be vertical mounted for optimal cooling.
Function
Check that the polarity between the charger and the battery is right. Positive + to positive + and negative – to
negative -. Red cable is plus and black cable is minus.
The charging starts after a few seconds and the status indicator, Yellow LED, is lit up.
Yellow LED remains on until the battery is fully charged. If the charger is connected to a fully charged battery
the charger will be charging for 1 hour. This is the minimum charging time. During this phase the green led will
be illuminated. When only green LED is on the charger is kept in maintenance charger and ready to be used.
Maintenance charging will continue as long as the battery is connected.
The charger will be reset as soon as the charger is switched off and on, or if the battery is disconnected .
The charging time depends on the size of battery and the depth of discharge.
A freely ventilated battery (Wet) can be discharged to max. 80% and a valve regulated (Dry) with max 70%.
OBS: Switch off the charger before the battery is disconnected. If the battery is disconnected without switching
of the charger, sparks may be produces.
