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 SAE-72 (12V outlet connector for auto and DIN socket) or

SAE-79 (Extended 12V DIN connector with weatherproof cap).

The SAE-79 accessory is delivered with the CAN-bus Edition of OptiMate 4.

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.

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low to power CAN-bus / Outdated CAN-bus programming on the vehicle - consult with the vehicle manufacturer.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 - Current up to 0.8A is delivered in pulses to prepare the battery to accept full current charge.

CHARGE: LED #4

BULK charge - A constant current of 0.8A up to a voltage of 14.2 -14.4V is delivered to the battery.

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

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.
