Product Manual

It is possible that with dual axles brakes, heavy brake light loads, warm batteries,
a large load on the trailer etc, that the battery is sufficient but failing to give a clear
pass.
It is necessary that there is at least 10Ah of useful battery capacity remaining, which
may require 20% of aged 100Ah-rated battery for this load. If any loads (e.g. lights,
12V fridges) are on in the trailer, turn these off if possible. If your trailer or caravan
has a display showing remaining battery capacity this should be able to provide a
useful indication that there is enough battery capacity remaining for the emergency
braking function.
Refer to the LED Status Indicators section of this manual for information.
Can I use a wired in-car monitor?
A wired 12VDC battery voltage indicator can be used with the TrailSafe or TrailSafe+
if desired.
When I pull the pin, the LED display is flashing RED and ORANGE?
The pull pin is faulty, which may cause the brakes to not operate correctly or for as
long as desired.
Refer to the LED Status Indicators section of this manual for information.
I have charged my house battery, but the TrailSafe shows a RED LED.
If a large load is applied to the house battery, such as a fridge, the house battery
terminal voltage may drop below the minimum TrailSafe threshold, due to the
internal resistance of the house battery.
Switch off any loads and re-test.
Refer to the LED Status Indicators section of this manual for information.
I thought it was not a good idea to remove the pin?
This is a key feature of the device. By removing the pin to test the unit, it checks to
ensure that the switch is functioning. It also checks the battery is ready to function
should an emergency happen.
The LED is indicating a solid RED all the time?
The battery voltage is very low and is considered flat. Charge or replace the battery.
