ABOUT THE TRAIL SAFE

The TrailSafe is a system designed to activate the electric brakes of a trailer or caravan (or similar) in the event of a disconnection from the towing vehicle. It utilises the house battery located on the trailer to activate the electric brake system and brake lights on the trailer in an emergency breakaway situation.

The TrailSafe also provides an indication of the charge status of the house battery and checks the condition of the pull pin and effective activation of the brakes. This information is displayed via a multi-coloured LED on the TrailSafe unit. This can also be displayed on the Bluetooth TrailCheck available for in-car monitoring if installed.

The mechanical pull pin is forcibly detached if the towing vehicle becomes separated from the trailer. Upon disconnection, the brakes and brake lights are activated as long as charge remains in the trailer battery or until the pin is replaced.

There are two available models in the TrailSafe series: the TrailSafe and TrailSafe+. The TrailSafe+ includes an extra cable to integrate it with BMPRO’s SwayControl.

KEY FEATURES

Bluetooth and wired connectivity options for in-vehicle monitors
Works off house battery no additional battery required
LED status indicators for full system safety check at trailer tongue
Tests pull pin functionality as well as battery health
Activates brake lights as well as electric brakes in the event of a breakaway
When wired to BMPRO’s proactive electronic stability control SwayControl and used with the wireless in-car monitor, provides comprehensive data on the RV safety system (only available with TrailSafe+)
Meets Australian regulations for break away systems on trailers over 2000kgs

VEHICLE STANDARDS

Australian Design Rule 38/05 mandates that for all trailers having a Gross Trailer Mass over 2000 kg, an emergency braking system is required on all wheels and must be capable of automatically activating should the trailer become detached from the tow vehicle. In such a situation the brakes must remain active for a minimum of 15 minutes.

INSTALLATION INSTRUCTIONS

MOUNTING LOCATION

Secure the TrailSafe or TrailSafe+ to the right-hand side drawbar of the trailer (the driver’s side) approximately 300mm from the tow ball hitch. Mount horizontally on top or side of the drawbar.

MOUNTING METHOD

Mount on the arm of the trailer using the supplied mounting screw or similar. Only one mounting point is required so that the unit can swivel in an emergency. Ensure that it is secured tightly so that it does not vibrate loose.

MOUNTING ORIENTATION

The wires should be pointing towards the rear (away from the tow vehicle) so that the pull pin is facing towards the tow vehicle. The pull pin will then be pulled out freely should the vehicle and trailer separate. The other end of the pull pin cord is attached to the towing vehicle by a D-shackle or similar.

TRAILSAFE WIRING DIAGRAM

*Refer to your display monitor’s manual for connection instructions.

TRAILSAFE+ WITH SWAY CONTROL WIRING DIAGRAM

*Refer to your display monitor’s manual for connection instructions.

WARNING
Do not connect the TrailSafe+ blue wire directly to trailer brakes if the SwayControl is also installed. Failure to do so disables the unit’s ability to control sway.
WARNING
If you have a BP35/J35 installed, all negatives must pass through the BP35/J35 before connecting to the house battery.

WARNING
If you have a BC300 installed, all negatives must pass through the BP35/J35, and then the BC300 before connecting to the house battery.
The return (negative) wires of the brakes and brake lights from trailer must be wired directly to:

One of the negative output connections on BatteryPlus35 or J35 if fitted
To the non-battery side of a negative side shunt such as the BC300
Directly to the battery negative in all other cases

Ensure the house battery has a suitable charging source such as a BatteryPlus35, J35, or other charging means and is functioning correctly. Refer to the manufacturer’s instructions for these products as required. A basic charging means such as diode from the Auxiliary to the house battery may be employed in simple systems.

An external automotive-grade fuse is required to be fitted (30A maximum) between the TrailSafe / TrailSafe+ and the battery to protect against wiring faults and issues.

INITIAL SELF-TEST

Before starting, ensure the TrailSafe or TrailSafe+ pull pin is in place.
Power up the TrailSafe or TrailSafe+ from your 12V battery as per the wiring instructions. The LED will display a continuous flashing PURPLE, indicating the first stage of calibration is in progress. This will last for up to 5 minutes.
When the first stage is completed, the LED will display a solid PURPLE. When this happens, pull the safety pin out. The LED will display a continuous flashing PURPLE again, indicating the second stage of calibration is in progress. This will last for up to 1 minute.
If the LED indicates an alternating PURPLE/RED, the wiring Voltage Drop in the black/red wire (+v) and/or the white wire (-v) is exceeding 10% of the nominal voltage. Check the wiring connections and consider increasing the black/red and/ or the white wire size.
Once completeted, LED will display a solid PURPLE again. At this stage, put the pull pin back in. The LED will then display a status indicator. For details, refer to the LED Status Indicators section of this manual.

FAQS AND TROUBLESHOOTING

Need more help troubleshooting your TrailSafe or TrailSafe+?
Contact our customer service team online at teambmpro.com/technical- support.
When I pull the pin, the TrailSafe indicator does not illuminate?

Check the supplied fuse on the black/red wire.
Check the wiring matches the diagram.
Ensure TrailSafe or TrailSafe+ pin slot is clean of dirt.
Ensure the house battery is charged.

Why should I test TrailSafe before hitching it to the tow vehicle?
Testing the TrailSafe or TrailSafe+ ensures that the house battery has sufficient capacity to operate the brakes for at least 15 minutes should the need arise.
What is the difference between a solid green, orange and red status indicators on the TrailSafe?

GREEN confirms that the battery has been detected, has been determined to have sufficient charge and no fault in the wiring to the brakes has been detected. Good to go!

ORANGE indicates there is a need for a secondary check as the battery may be too low.

RED indicates that the battery is not detected or does not have enough capacity for 15 minutes emergency brake operation.
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.
Refer to the LED Status Indicators section of this manual for information.
