Mobile Link 4G/LTE device LED indicators
The Mobile Link Cellular 4G LTE accessory device leverages cellular communication, as well as a direct connection to the generator's controller, to communicate the status and events that occur on a generator, through the Mobile Link Website and Android/iOS Apps. However, in order to successfully communicate the required information, a stable connection to the Cellular network and the Generator controller is required. In some cases, when communication is an issue, the lights that are displayed on the front of the device can help with understanding what issue may be present.
Note: All troubleshooting steps should only be performed by users comfortable with performing these actions. In some cases, it may be required to contact a local service dealer to assist in performing the troubleshooting steps, as some steps may include removing generator panels and accessing sensitive electrical areas of the generator.
Environment
This article is for compatible home standby generators that have the 4G/LTE accessory installed (Mobile Link network device overview and compatibility information). To troubleshoot generator LEDs that indicate warnings and faults listed on the generator controller, see: What Do the Green, Yellow, and Red Status Indicator Lights Mean on Home Standby Generators?
Guide to 4G/LTE LED indicator lights
Each light relates to a unique Icon. To simplify the reference to each light, they have been labeled on the image above, as A, B, C, and D.
- A - Power LED
- The light will illuminate if the Mobile Link device is receiving power from the battery or generator controller (Evolution 2.0 controllers only.)
- B - Cellular Network LED
- Indicates the cellular signal strength according to the Mobile Link device
- C - Connection to Controller LED
- Indicates the status of the Mobile Link Device's connection to the generator controller.
- D - Service Connection LED
- Indicate the status of the Mobile Link Device's connection to the Mobile Link Servers
All LEDs are off
This is an indication that there is no power to the Mobile Link Device. Resolutions to this issue may include:
- Inspect wire harness connections:
-
- Evolution 2.0 controller: Mobile Link cellular unit receives power directly from the controller.
- Non-Evolution 2.0 controllers: Mobile Link cellular unit receives power from battery connections.
- Inspect thermal safety device (fuse, in-line circuit breaker, or thermal coupler) in harness.
- Verify harness is correctly connected to the battery.
- Reset connector to Mobile Link cellular unit.
Only the power LED is off
This is an indication that there is no power to the Mobile Link Device. Resolutions to this issue may include:
- Inspect wire harness connections:
- Evolution 2.0 controller: Mobile Link cellular unit receives power directly from the controller.
- Non-Evolution 2.0 controllers: Mobile Link cellular unit receives power from battery connections.
- Inspect thermal safety device (fuse, in-line circuit breaker, or thermal coupler) in harness.
- Verify harness is correctly connected to the battery.
- Reset connector to Mobile Link cellular unit.
Only the Power LED is on, all other lights off
This may indicate a failure with the device itself. Replacement devices are handled through an authorized service dealer.
Note: Generac support recommends contacting a local service dealer for the below troubleshooting steps.
- Verify the generator is compatible: Which generator controllers are compatible with aftermarket installation of the Wi-Fi, Ethernet, or 4G LTE? devices
- Unplug each connection between the LTE device and controller, visually inspect each plug, including the pins to make sure they are good and secure, then reconnect.
- Verify harness connections between Mobile Link cellular unit and generator controller are in the correct configuration.
- Wait a few moments. Upon initial startup, Mobile Link will not attempt to communicate with controller for approximately 15 seconds.
- Inspect wire harness and battery connections (if applicable); tighten if necessary.
- If the issue persists, try replacing the harness.
- Perform a full hard reset of the generator and controller: How Do I Perform a Hard Reset on a Home Standby System?
- If the generator is a liquid-cooled generator. You need to verify that the proper harness was used during installation. Device kits come with a harness that is for air-cooled units only. The part number for the proper harness is: G0064780.
- If the issue persists, contact an authorized service dealer to reach out to Generac technical support.
Power LED flashing or flickering
This is typically an indication of a loose power connection to the Mobile Link Device. Resolutions to this issue may include:
- Verify harness is correctly connected to the battery or generator controller (Evolution 2.0 controllers only.)
- Reset connector to Mobile Link cellular unit.
Cellular LED flashing or off
This typically signals a variable or weak connection to a cellular network signal. Resolutions to this issue may include:
- Reset connector at generator controller and Mobile Link cellular unit. Verify external antenna is attached tightly to the Mobile Link cellular unit.
- Verify external antenna is attached tightly to the Mobile Link cellular unit. Replace cable.
Wait for the situation to resolve itself. LED should stop flashing within 10 minutes. If not:
- Purchase an extender antenna
- Contact Customer Support
Note: Cellular coverage may be intermittent. Verify Verizon's cellular coverage strength by trying to make a phone call from a Verizon-supported mobile phone near the Mobile Link cellular unit, or contact Verizon directly.
Connection to the controller LED is off
This is an indication that the Mobile Link cellular unit is either not connected to the generator's controller or has a poor connection to the generator's controller.
Note: Generac support recommends contacting a local service dealer for the below troubleshooting steps.
- Unplug each connection between the LTE device and controller, visually inspect each plug, including the pins to make sure they are good and secure, then reconnect.
- Verify harness connections between Mobile Link cellular unit and generator controller are in the correct configuration.
- Wait a few moments. Upon initial startup, Mobile Link will not attempt to communicate with controller for approximately 15 seconds.
- Inspect wire harness and battery connections (if applicable); tighten if necessary.
- If the issue persists, try replacing the harness.
- Perform a full hard reset of the generator and controller: How Do I Perform a Hard Reset on a Home Standby System?
- If the issue persists, contact an authorized service dealer to reach out to Generac technical support.
Connection to Controller LED is flashing
This is typically an indication that the mobile link device has not been able to determine the type of control panel it is attached to, and as a result, cannot properly decipher the information that is communicated. Resolutions to this issue may include:
- Verify controller is compatible with the Mobile Link cellular unit. (Pre-Nexus, Nexus, Evolution 1.0, and Evolution 2.0)
- Verify all harness connections between the Mobile Link cellular unit and generator controller are correct and tight.
- Perform troubleshooting as outlined in the "Controller LED is off" section.
- If the issue persists, contact an authorized service dealer to reach out to Generac technical support.
Note: The light will turn solid when communications are established.
Server connection LED is off
This LED sequence can indicate a few scenarios. This can mean that the Mobile Link cellular unit is not connected to the Mobile Link servers, the controller is not a supported control panel, or the Mobile Link cellular unit is currently in “Suspended” mode. Resolutions to this issue may include:
- If the Mobile Link cellular unit is not connected to the Mobile Link server: The Mobile Link Service may be down. It may self-correct, and it is likely worth waiting a few hours for server response or contact Mobile Link Customer Support at 1-855-436-8439 (US) or 1-844-843-9436 (CAN).
- If the Device is attached to an unsupported control panel: Verify control panel is Pre-Nexus, Nexus, Evolution 1.0, or Evolution 2.0 as the device is only supported on these controller types.
- If it is suspected that the Mobile Link cellular unit is in “Suspended” mode: Contact Mobile Link Customer Service for assistance: (US) 1-855-436-8439
(CAN) 1-844-843-9436
Server connection LED is flashing
This is an indication that the Mobile Link cellular unit is connected to Mobile Link servers, but the connection is not verified. Resolutions to this issue may include:
- Typically, the server connection pending. Wait for the server's response. The connection process may last as long as 10 minutes.
