Procedures

6
Installation and Setup Test diagnostic
  1. Verify generator set operation using the Start/Stop switch located on the generator set.
  2. Verify manual start/stop of the generator set from the app dashboard using the START and PRIME/STOP buttons.
  3. Check operation of the temperature sensors with Auto mode and Air Conditioning Sense enabled.
  4. Verify the generator set starts automatically when the settings are met.
  5. Verify the accelerometer by driving the vehicle at 10 mph and checking that AGS is automatically disabled.
  6. Verify delayed shutdown: enable AGS, allow the generator set to start, disable AGS, confirm shutdown in 10 minutes.
Connect Components (EC-AGS+ Gateway) installation

⚠ Accidental starting of the generator set can cause severe personal injury or death. Disconnect the starting (battery) cables before performing service.

⚠ Always disconnect a battery charger from its AC source before disconnecting the battery cables.

⚠ Seal all holes to prevent the entrance of exhaust gases into the vehicle interior.

  1. Plug the 12-pin connector from the harness to the EC-AGS+ gateway.
  2. Route the other end of the harness from the gateway to the Y-harness.
  3. For gas generator sets, plug the 8-pin EC-AGS+ harness connector into either lead of the Y-harness.
  4. For diesel generator sets, plug the 10-pin EC-AGS+ harness connector into the longer lead of the Y-harness.
  5. Connect the main lead of the Y-harness to the generator set.
  6. Connect the remaining Y-harness connector to the remote start/stop switch harness.
  7. Route the red wire lead to the positive terminal of the generator set starting battery and extend as necessary using butt connectors.
  8. Provide circuit protection by installing a 5 Amp fuse in the red wire lead.
  9. Locate the common ground location on the vehicle and route the black wire lead to the common ground.
  10. Route the grey wire lead to the engine battery positive terminal (optional connection).
  11. Insert battery ring terminal to the wires and connect the wires.
  12. Use cable ties at not less than 0.5 m (20 in) intervals to keep the wire bundle neat.
Connect Temperature Sensor(s) installation

Tools: Small flathead screwdriver

  1. Remove the lid from the sensor using a small flathead screwdriver.
  2. Remove the plastic battery tab from the sensor to enable the battery to provide power to the sensor.
  3. Place the lid back on the sensor.
Mount Components installation

⚠ High ambient temperature can cause damage to the EC-AGS+ gateway.

  1. Do not install the EC-AGS+ gateway directly inside the generator set compartment.
  2. Mount the EC-AGS+ gateway in a suitable, easily accessible location.
  3. Drill holes for the fastening screws and mount the EC-AGS+ gateway using mounting screws.
  4. Mount the temperature sensor(s) near an A/C thermostat (one per zone, 3 maximum).
  5. Drill 2 holes for screws and mount the sensor.
Temperature Sensor Battery Replacement maintenance

⚠ Pushing on the cover too hard can damage or break it.

Tools: Small flathead screwdriver

  1. Make sure the generator set is not set to start in Auto mode.
  2. Remove the top cover of the temperature sensor using a small flathead screwdriver.
  3. Slide the battery out of the battery holder and remove the battery.
  4. Slide the new battery into the battery holder and replace the cover.
Configure System Using App (Getting Started) operation

⚠ For first time set up or after factory reset, the vehicle must be kept stationary for at least 30 seconds to allow the gateway accelerometer to be configured properly.

  1. Download the EC-AGS+ app from the AppStore for iOS or Play Store for Android.
  2. Reconnect the generator set negative battery cable to power on the EC-AGS+ gateway.
  3. Verify that the EC-AGS+ gateway is powered by observing the LED blinking every 5 seconds.
  4. Turn on Bluetooth on the device containing the app.
  5. Select the EC-AGS+ App and select Start.
  6. Connect the gateway to the app via Discover EC-AGS+, Scan QR code, or gateway password.
  7. Read the End User License Agreement to the end and select Agree.
  8. Create a new password and select Assign Password.
  9. Select the generator set model and type; enter the Start Hours from the hour meter if available.
  10. Select Proceed to Dashboard.
