Using 12V batteries
Shutdown when the output voltage is less than 11.0 volts.
Single battery warning when the voltage is less than 11.9 volts.
Single battery warning when percent reading is less than 20%.
24V Line warning when the output voltage is less than 11.9 volts.
Low voltage warning when less than 10% of all batteries.
Low Voltage warning when all 12V voltages are less than 11.9 volts.
Overvoltage warning if more than 25 volts are measured with 12 volt batteries
8.7.11 General Working Method / BHM-2
Overview
The Battery Hanger Module BHM-2 provides constant 12V and 24V
regardless of whether 12V or 24V batteries are connected.
Use of 12V batteries
If up to three 12V batteries are connected, 12V will be supplied
directly to the 12V consumers.
As soon as a 24V consumer is detected, the BHM-2 supplies
a regulated 24 voltage to this consumer.
The 12 volt supply is shown in percent as long as battery
communication is available, the 24 volt supply is shown in volts only.
Use of 24V batteries
If up to three 24V batteries are connected, 24V will be supplied
directly to the 24V consumers.
As soon as a 12V consumer is detected, the BHM-2 supplies
a regulated 12 voltage to this consumer.
The 24 volt supply is shown in percent as long as battery
communication is available, the 12 volt supply is shown in volts only.
