All SLXi trailer units come fitted as standard from factory with a Low Voltage Disconnect (LVD)
Switch to accommodate for 3rd party device connections. The LVD switch ensures that all SLXi
units provide a dedicated device connection point for external devices, while also preventing
battery discharge/depletion of the EON battery during unit idle periods.
This new LVD switch replaces the previous optional aftermarket solution, the battery safeguard.
Example of “external devices” which are required to be powered through the LVD switch
connection points include:
•
Third party telematics
•
TouchPrint printer
•
TouchPrint dataloggers

ntt:: All external device connections must be connected through the LVD switch as per
instructions detailed below. Failure to connect external devices through the LVD
switch may result controller and/or battery related failures being rejected by
warranty. The LVD switch acts as a protective medium between the SLXi unit
electrical system and external device(s).
How it Works
The LVD switch acts as a protective medium between the SLXi unit electrical system and external
device(s).
The function of the LVD switch is as follows:
•
Disconnects power to external devices when battery voltage drops below 12.1V (for longer
than 5-7 minutes).
•
Automatically resets when system voltage rises above 13V (for longer than 10 seconds).
•
Provides connection point in control box for up to 3 external devices.
