INITIAL SELF-TEST
1. Before starting, ensure the TrailSafe or TrailSafe+ pull pin is in place.
2. 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.
3. 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.
4. 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.
5. 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.
