PROGRAM 2 - CAN-bus
IMPORTANT: High voltage STANDARD and RECOVERY CHARGE modes are disabled. This program is designed for charging, testing
and long term maintenance of batteries mounted in vehicles fitted with CAN-bus.
RECOMMENDED: Charge through the 12V outlet with the appropriate O-2 (12V outlet connector for auto and DIN socket) or O-9
(Extended 12V DIN connector).
LED INDICATIONS BEFORE CONNECTION TO THE BATTERY:
LED #3 and 4 flashing: The program is sending a signal to detect and activate a CAN-bus controlled 12V outlet.
LED #3, 4, 5, 6 and 7 flashing: A short circuit has been detected across the output terminals, or if LED #2 (REVERSE POLARITY)
is also indicating the battery connections are incorrect. The charger is electronically protected so no damage will result, and the
output will remain disabled until the connections are corrected.
PRE-QUALIFICATION TEST: LEDs #5 / 6 / 7
TEST LEDs #5/6/7 indicate successful activation of the CAN-bus controlled 12V outlet and the condition of the battery
prior to charging. Charging commences after 10 seconds. Consult the "EARLY WARNING OF BATTERY PROBLEMS" table on
page 2 (illustration 2) for TEST LED indications.
NOTE: Non activation may be due to one of the following: Program 1 is selected / Poor connection to the 12V outlet / Battery too
low to power CAN-bus / Outdated CAN-bus programming on the vehicle - consult with the vehicle manufacturer.
RECOVERY / DESULPHATE: LED #3
This mode engages if during pre-qualification LED #7 (red) or LED #6 (yellow) or both indicated. The CAN-bus
program can only select low voltage PULSE recovery mode. Charge time: 15 minutes.
PULSE recovery - LED #3 steady on: Current up to 0,8A is delivered in pulses to prepare the battery to accept full
current charge.
CHARGE: LED #4
BULK charge - LED #4 steady on: A constant current of 0,8A up to a voltage of 14,2 -14,4V is delivered to the battery.
FINAL charge - LED #4 flashing: Pulsed absorption step: Current is delivered in pulses, varying between 0,2 and 0,8A and up to
a voltage of 14,2 - 14,4V, to bring the battery to full charge in the shortest possible time. Verification step: Once the current
demand is less than 0,2A the charging voltage is now limited at 13,6V whilst the battery's charge level is verified.
If the battery requires further charging the program will revert to pulsed absorption.
If the battery has accepted as much charge as its basic condition allows the voltage retention step follows.
NOTE 1: The program automatically resets 2 minutes after manual disconnection or if the CAN-bus system has de-activated the
controlled 12V outlet and the program could not re-activate the outlet within 2 minutes.
NOTE 2: For safety reasons there is an overall charge time limit of 48 hours.
VOLTAGE RETENTION TEST: LED #5 flashing
Delivery of current to the battery is interrupted for 30 minutes to determine the battery's ability to retain charge. This will prompt
the CAN-bus system to disable the 12V outlet within it's own set time limit, disconnecting the battery from the charger. At the
conclusion of the test period the program will once again initialize the CAN-bus controlled 12V outlet to measure the battery's
voltage and then proceed to MAINTENANCE CHARGE during which the result of the test is displayed.
Consult the “EARLY WARNING OF BATTERY PROBLEMS” table on page 2 for LED indications. Read the section NOTES ON TEST
RESULTS on reasons for poor test results or how to test a battery that returns a good result but cannot deliver sufficient power
once it is returned to service. NOTE: If during the test the charger is manually disconnected from the 12V outlet or battery it will
not automatically reset until the end of the test period.
MAINTENANCE CHARGE: LED #5 / 6 / 7 steady on
For 30 minutes the circuit offers current to the battery within a safe 13,6V voltage limit whilst the result of the voltage retention
test is displayed. The 30 minute float charge maintenance periods follow and alternate wih the 30 minute VOLTAGE RETENTION
TEST periods until the battery is disconnected. A more detailed description of the automatic maintenance cycle for long term
battery storage can be found under the section AUTOMATIC BATTERY MAINTENANCE.
NOTE 1: The program automatically resets 2 minutes after manual disconnection or if the CAN-bus system has de-activated the
controlled 12V outlet and the program could not re-activate the outlet within 2 minutes.
