In our specifications we ask to connect at least 4 mandatory wires and an additional one depending of the machine isolator type.
Among those 4 (+1) wires we have :
- The red and the dark blue wires. They are the wire for the unit power supply. To allow the unit to wake up and work and charge the internal backup battery the unit need to be connected to a proper power supply. The red wires is the (+) and the dark blue for the ground signal (-) .
The 2 others mandatory inputs are the white wire (input 1) and the brown wire (input 2)
- The White wire (IN1) signal will mainly be used to determine the machine activity (total hours or productive hours) , the machine status and engine status.
- The Brown wire (IN2) signal will allow the system to capture operating time, and the unit to register trips, kilometers and odometer. It is also the default signal as access control sensor and is also the signal that trigger the CAN data readings when connected. This input is also a backup solution for idle time calculation.
All those data are used by our different activity and reporting capabilities, and if one signal is missing it will reduce or remove the data quality.
- The optional mandatory wire is the Pink wire (Input 4) which requires to be connected to a chassis ground signal in case of negative isolator on the machine. Reason is to avoid false activity issue (see https://community.trackunit.com/got-a-question-7/why-my-machine-is-working-24-hours-136)
