CHARGE LEDS
8.5.1.
4 red percentage charge LEDs. When charge = 100% charger enters Maintenance mode.
8.6.
RESET
8.6.1.
When connected to power supply device will reset itself to standby state if no other modes are selected.
8.7.
MODE 1 (28.8V/3.5A) 24V BATTERY
8.7.1.
Mainly used for batteries with larger capacity of more than 14Ah in normal condition.
8.7.2.
Connect output terminals to battery with correct polarity and press MODE button to select 24V mode.
8.7.3.
Corresponding 24V LED will light up together with % LED. Charging will begin with 3.5A±10% current. Light will remain on during
charging up to 28.8V±2%.
8.7.4.
When battery is fully charged the charge 100% LED will turn on and a trickle current will maintain the battery.
8.8.
MODE 2 (14.4/7A)
8.8.1.
Mainly used for batteries with larger capacity of more than 14Ah in normal condition.
8.8.2.
Connect output terminals to battery with correct polarity and press MODE button to select 12V mode.
8.8.3.
Corresponding 12V LED will light up with % LED. Charging will begin with 7A±10% current. LED will remain on until battery is charged
up to 14.4V±0.25V.
8.8.4.
When battery is fully charged the charge 100% LED will turn on and a trickle current will maintain the battery.
8.9.
MODE 3 13.6V SUPPLY (13.6V/5.0A)
8.9.1.
Mainly used for batteries with larger capacity of more than 14Ah in normal condition or to use as a 13.6V/5.0A power supply. The
charger has an overload protection feature (6.0A max.) If output voltage falls below 4.5V the charger returns to Standby mode.
CAUTION! There is no reversed polarity protection.
8.9.2.
Maintenance 12V SLA batteries
Connect output terminals to battery with correct polarity and press MODE button to select the correct mode. The corresponding LED
13.6V/supply will light and the unit will supply 'maintenance' at 13.6±0.5V and 5A±10%.
8.9.3.
Power source
Press MODE button for more than 3 seconds, LED 13.6V/supply will illuminate and the power source will supply 13.6V±0.5V and
5A ±10 constant voltage and current output.
8.10.
MODE 4 16V boost (16V/1.5A) 12V battery only
8.10.1.
For recovering batteries with a larger capacity of more than 14Ah in normal condition.
8.10.2.
Connect output terminals to battery with correct polarity and press MODE button to select the correct mode. The corresponding
LED '16V boost' will illuminate and the unit will start the recovery mode at 16.5V±0.5V and 1.5A±0.5A. If the battery is very flat,
(deep discharged and sulphated, the LED '16V boost' may continue to indicate for up to 3 hours whilst a special high voltage (about
17V maximum) is applied to force a fixed current (1500mA) into the battery in a recovery attempt. After 4 hours maximum or as soon
as the battery can accept the normal charging programme, the LED '16V boost' will flash with 0.5s on 1s off.
8.11.
PULSE RESCUE DEAD BATTERY
8.11.1.
Once connected to a battery the charger detects the battery's voltage and will begin pulse charge mode if the battery's voltage is
within the range of 4.5±0.5V or 16V±0.25V to 10.5V± or 21V±0.25V for 12V or 24V battery.
8.11.2.
The pulse charging mode will not stop until the battery voltage rises to 10.5V±0.5v or 21V±0.25V.
8.11.3.
If pulse charging continues for over 6 hours and the battery voltage is below 10.5±0.5V or 21V±0.25V for 12V or 24V battery, the
charger will return to power mode. Once this point has been reached the charger changes to the normal charging mode selected by
the user at the beginning and now the battery will be charged up quickly and safely.
8.12.
ABNORMALITY PROTECTION
8.12.1.
Whenever one of the following abnormalities, such as:
-short circuit,
-recovery mode over hours,
-bulk charging over 41 hours,
-12V battery voltage below 4.5±0.5V,
-24V battery voltage below 15V± 0.25V,
-open circuit or reverse connection of the output terminals;
the charger will turn off the electronic switch and automatically resets the system immediately to avoid damage.
8.12.2.
If there is no further input received, the system will remain in the standby state of power mode. Additionally, if reverse connection
happens, the ! LED will illuminate to indicate the mistake.
8.13.
TEMPERATURE PROTECTION
8.13.1.
If the charger becomes too hot for any reason, it will reduce its power output to protect itself from damage.
