Monitor a PTO/Fuel Pump - G70

The G70 has 3 x Digital Inputs (+1 dedicated Ignition Digital Input). We can use a Digital Input to to monitor a secondary bit of equipment on an asset, i.e. sprayer, fuel pump, PTO.

In most cases, we wire and configure the input in the same way as our dedicated ignition input (the white wire on the G70). 

We consider the input 'on' when there is voltage present at the input (a high signal), and off when there is no voltage. 

Wiring

Connect the Dart3 ground wire (any black wire) to ground on our asset, and our chosen digital input wire to the high side of the pump/PTO etc.

  • Digital Input 1 = BLUE 
  • Digital Input 2 = ORANGE
  • Digital Input 3* = PURPLE

*Digital Input 3 is shared with one of the Driver ID lines, so DI3 cannot be used at the same time as a DM RFID reader, or Wiegand Reader

The Digital Input is considered on when above 2.2V, and off when below 0.8V.

Parameters

The configuration would be:

  • Bias resistor set to 'pull down'
    • When not running, there is no voltage present on the input. It is held low.
  • The Active Level is set to high
    • When running, there is a high voltage signal at the input.
    • The digital input is considered on. 
  • If we want to know in real-time if we are on or off, we should set Upload on Active and Upload on Inactive = Yes.

Further Applications 

Once we are tracking the status, we are able to enable further functionality:

Secondary Run Hours (TG)

We can track the hours that a Digital Input is active in Telematics Guru. See Setting up Secondary Run Hours.

Asset State Configuration (TG)
Depending on the state of the Digital Input, Telematics Guru can show the asset as a different colour in the Live View and Trip History View, i.e. spraying is occurring.  See Asset State Configuration
Configure Alerts and Run Reports (TG)
Events and Alerts may be used to setup reports on Telematics Guru. See guide here - Events vs Alerts
Input Monitor
Create alerts based on the status of multiple inputs - G70 - Input Monitor
