ProMariner Digital Mobile Charge Battery - Manual (Page 4)

Details of Operation:
Digital Mobile Charge begins operation by monitoring the engine start battery. The unit will not
start until the battery voltage exceeds approximately 13 volts for 12V models (26V for 24V
models), then waits for 2.5 minutes to ensure that some charge is placed quickly into the engine
start battery. After that, the Digital Mobile Charge pulls the engine battery down to no less than 13
volts for 12V models (26V for 24V models), which enables the engine battery to still receive a
small charge and ensures the alternator works at its full potential.
Additionally, to further ensure the engine battery is O.K., every 20 minutes the Digital Mobile
Charge stops for 3 minutes, allowing the engine start battery to be charged exclusively by the
alternator. After the 3 minutes, the Digital Mobile Charge resumes battery bank charging by pulling
down the engine start battery to 13 volts for 12V models (26V for 24V models) and so continues
the charging cycle. After a period of time, calculated by the software, when the battery bank
batteries are full, the system will float the batteries at 13.5 volts for 12V models (27V for 24V
models) all while ensuring the viability of the engine battery comes first.
Other features included in this system are an alternator temp sensor, a remote battery temp
sensor and a fully automatic sleep sensor, which switches the unit off when the engine has
stopped.
General Safety Instructions:
• Before connecting your batteries, read all instructions and cautionary markings on
the battery charger and batteries.
• CAUTION - To reduce the risk of injury; charge only lead acid type rechargeable batteries
(lead acid, gel cell and AGM). Other types of batteries may burst, causing personal injury.
• Use of attachments not recommended or sold by On Board Solutions or Professional
Mariner, LLC may result in a risk of fire, electrical shock or personal injury.
• Do not operate the charger if it has received a sharp blow, direct hit of force, dropped or
otherwise damaged in any way.
• Do not disassemble the charger. Call the factory directly when service or repair is required.
• Incorrect assembly may result in risk of electrical shock or fire.
WARNING: RISK OF EXPLOSIVE GASESWORKING IN THE VICINITY OF A LEAD ACID
BATTERY IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL
BATTERY OPERATION. FOR THIS REASON IT IS OF EXTREME IMPORTANCE THAT EACH
TIME BEFORE USING YOUR CHARGER YOU FOLLOW THE SAFETY INSTRUCTIONS
FOUND IN THIS MANUAL.
To reduce risk of battery explosion, follow these instructions and those published by the
Battery manufacturer, and of any equipment you intend to use in the vicinity of a battery.
Review all cautionary markings and labels.
