VANNER Incorporated Theory of Operation Theory of Operation +24V F2 + 12 V Battery B - +24V VANN-Guard +12V F1 + 24V Alt - +24 Volt Loads +12 Volt Loads + 12 V Battery A - +12V GND In many 24 volt electrical systems it is desirable to tap into the battery system to obtain power for 12 volt loads. This method, while seemingly simple, causes a charge imbalance resulting in Battery B (see diagram) being overcharged, and possibly boiling, while Battery A discharges.
VANNER Incorporated Theory of Operation Smart Monitor Functionality All functionality described in this section requires that the Monitor Ignition Input (Terminal B) be connected to +24v in order to be active. A. Not Connected This pin is not currently used. It is reserved for Vanner use. B. Smart Monitor Ignition (Enable) Input This input powers the equalizer monitor. When this pin is taken to +24V the monitor becomes active. C.

VANNER Incorporated Installation Instructions Installation Instructions These symbols are used to note procedures that if not closely followed could lead to loss of life or damage to equipment or property due to electrocution. Electrocution hazard exists Fire hazard exists A potentially dangerous condition Explosive hazard exists Corrosive hazard exists Do not exceed the specified torque of 120 in-lbs.
VANNER Incorporated Installation Instructions Environmental Protection – Your VANN-Bus has been designed to withstand direct exposure to rain and moisture. The VANN-Bus has also been tested for exposure to direct pressure spray, but continual exposure to direct pressure spraying may reduce the VANN-Bus serviceable life. Any damage due to water contamination is covered by Vanner only through the terms of our factory warranty. Wiring Sequence– The VANN-Bus is internally protected for reverse polarity.
VANNER Incorporated Installation Instructions Caution adding 12volt batteries Acceptable +24V + 12 V Battery B - Unacceptable +24V Battery A and Battery B Are The Same Size F2 Battery A and Battery B Are NOT The Same Size F2 + 12 V Battery B - +24V VANN-Guard +24V VANN-Guard +12V +12V + 24V Alt - + 12 V Battery A - GND +12V F1 F1 + 12 V Battery A - + 12 V Battery A - + 12 V Battery A - + 24V Alt - + 12 V Battery A - +12V GND F1 + 12 V Battery A - + 12 V Battery A - + 12 V Battery A
VANNER Incorporated Installation Instructions Wire Size and Temperature Rating Cables connecting the VANN-Bus to the batteries must be sufficiently sized to prevent unwanted voltage drops. These voltage drops (loss) must be less than 0.05 VDC between the VANN-Bus’s +24 volt terminal and the battery +24 volt terminal (Battery B positive terminal), less than 0.10 VDC between the VANN-Bus’s +12 volt terminal and the battery +12 volt terminal (the jumper between Battery A and Battery B), and less than 0.
VANNER Incorporated Testing and Troubleshooting Testing and Troubleshooting CAUTION Servicing of electrical systems should only be performed by trained and qualified technical personnel. Equipment Required VoltMeter having 0.01 volt resolution. (Fluke Model 87 Multimeter recommended). Clamp-on current meter (Fluke Model 36 Clamp-on Meter recommended). Vanner Repair Service Vanner offers a quick turn around factory repair service.
VANNER Incorporated 5. Testing and Troubleshooting a. Battery A voltage (voltage between the VANN-Bus’s +12 and GND terminals) b. Battery B voltage (voltage between the VANN-Bus’s +24 and +12 terminals) Subtract Battery A voltage from Battery B voltage and compare readings. VANN-Bus Status Voltage Comparison a. b. c. Battery A is lower than Battery B but within 0.05 volt. Battery A is lower than Battery B by 0.05 to 0.10 volts. Battery A is lower than Battery B by more than 0.10 volts d.
