Procedures
6Installation and Setup Test diagnostic
- Verify generator set operation using the Start/Stop switch located on the generator set.
- Verify manual start/stop of the generator set from the app dashboard using the START and PRIME/STOP buttons.
- Check operation of the temperature sensors with Auto mode and Air Conditioning Sense enabled.
- Verify the generator set starts automatically when the settings are met.
- Verify the accelerometer by driving the vehicle at 10 mph and checking that AGS is automatically disabled.
- 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.
- Plug the 12-pin connector from the harness to the EC-AGS+ gateway.
- Route the other end of the harness from the gateway to the Y-harness.
- For gas generator sets, plug the 8-pin EC-AGS+ harness connector into either lead of the Y-harness.
- For diesel generator sets, plug the 10-pin EC-AGS+ harness connector into the longer lead of the Y-harness.
- Connect the main lead of the Y-harness to the generator set.
- Connect the remaining Y-harness connector to the remote start/stop switch harness.
- Route the red wire lead to the positive terminal of the generator set starting battery and extend as necessary using butt connectors.
- Provide circuit protection by installing a 5 Amp fuse in the red wire lead.
- Locate the common ground location on the vehicle and route the black wire lead to the common ground.
- Route the grey wire lead to the engine battery positive terminal (optional connection).
- Insert battery ring terminal to the wires and connect the wires.
- 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
- Remove the lid from the sensor using a small flathead screwdriver.
- Remove the plastic battery tab from the sensor to enable the battery to provide power to the sensor.
- Place the lid back on the sensor.
Mount Components installation
⚠ High ambient temperature can cause damage to the EC-AGS+ gateway.
- Do not install the EC-AGS+ gateway directly inside the generator set compartment.
- Mount the EC-AGS+ gateway in a suitable, easily accessible location.
- Drill holes for the fastening screws and mount the EC-AGS+ gateway using mounting screws.
- Mount the temperature sensor(s) near an A/C thermostat (one per zone, 3 maximum).
- 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
- Make sure the generator set is not set to start in Auto mode.
- Remove the top cover of the temperature sensor using a small flathead screwdriver.
- Slide the battery out of the battery holder and remove the battery.
- 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.
- Download the EC-AGS+ app from the AppStore for iOS or Play Store for Android.
- Reconnect the generator set negative battery cable to power on the EC-AGS+ gateway.
- Verify that the EC-AGS+ gateway is powered by observing the LED blinking every 5 seconds.
- Turn on Bluetooth on the device containing the app.
- Select the EC-AGS+ App and select Start.
- Connect the gateway to the app via Discover EC-AGS+, Scan QR code, or gateway password.
- Read the End User License Agreement to the end and select Agree.
- Create a new password and select Assign Password.
- Select the generator set model and type; enter the Start Hours from the hour meter if available.
- Select Proceed to Dashboard.
