Or by connecting special I-LBA Low Battery Adaptor module:
The I-LBA module ensures min. 350ms voltage dip under following conditions:
RS232 and other plug-in module is connected.
Voltage before dip is 12V and after 350ms the voltage recovers to min. allowed voltage 5V.
The I-LBA enables controller operation from 5VDC (for 10 to 30 sec).
The wiring resistance from battery should be up to 0.1 Ohm for I-LBA proper function.
Hint:
I-LBA may not eliminate voltage drop when used with low temperature (-40°C) version of controller
and display heating element is on (below 5°C). Current drain of heating element exhausts LBA
capacitors very fast.
Power supply fusing
A one-amp fuse should be connected in-line with the battery positive terminal to the controller and
modules. These items should never be connected directly to the starting battery.
Fuse value and type depends on number of connected devices and wire length.
Recommended fuse (not fast) type - T1A. Not fast due to internal capacitors charging during
power up.
