Other checklist items for Site Deployment include verifying voltage and the condition of circuit fuses. Please follow the steps in this table.

Pass/Fail

Site Deployment Prerequisites

  •  
  1. PWR LED should appear in a solid RED. Otherwise, check for any loose wires to V+/ V-.

  •  
  1. Measure the voltage across V+/ V- (9–48 DC).

  •  
  1. If there is no voltage, check for a blown fuse in the circuit.

  •  
  1. If the PWR LED is still not solid RED, the gateway may be faulty. Please refer to the gateway replacement section if necessary.

In the event that any of parts arrive damaged, please contact Support to open a ticket and request needed replacements.

Some factory-attached connectivity gateways initially shipped with the cellular antenna disconnected from the gateway. The issue has been corrected for new shipments. For existing inventory, please confirm that the pigtails coming from the gateway enclosure are connected to the antenna cables as illustrated in the following diagram (Red > Red/Black and Blue > Blue). This will ensure the gateway has adequate cellular signal strength to communicate with the connectivity platform.

Troubleshooting

Check this section to resolve any issues experienced while setting up the Advanced Gateway.

SIM Card Verification

Be sure to verify that the SIM card is in its proper location.

  1. Power off the gateway.

  2. To open the SIM card slot, a paper clip needs to be inserted in small hole located on card holder. Hole can be seen toward edge of extended holder in picture provided.

  3. Verify that the SIM card on arrival is inserted in the primary slot, as depicted in the photo, with chip wiring facing up. A backup slot (as part of the same tray) is available for a Hologram SIM card. If specifically requested to do so by Support, insert the SIM into the second position with chip wiring facing down.

SIM Tray on Left Panel

If proper insertion of the SIM card is verified and the signal remains insufficient, use the extension provided to place antennae to a location with a stronger signal. Be sure to speak with a local facility contact to inquire about coverage in the facilities.

If the NET indicator light is blinking for more than 15 minutes, check Verizon’s coverage map at this external resource: https://www.verizon.com/coverage-map/.

Using a LAN-Based Internet Connection

  1. Ports 443, 5671, and 8883 need to be opened for outbound traffic at facility firewall (if applicable).

  2. Run network cable from customer’s nearest network infrastructure to a laptop. Make sure a website is browsable from a laptop. If not, reach out to your organization’s IT team. Proceed to next steps if the web is browsable.

  3. Power off the gateway.

  4. Connect the network cable that was connected to laptop to the ETH2 port on the gateway (part number: A0005495703).

  5. Remove SIM card(s) from the gateway.

  6. Power on the gateway.

  7. Wait for 10–15 minutes then check the Generac Link Manager portal for live data stream. If the live stream is not current, please contact Support.

A video call using Microsoft Teams may be needed in order to share your screen with a solutions engineer.

Changing Communication Option from Serial to Ethernet

  1. Enable the Modbus TCP port on the controller.

  2. Set the controller IP address in 192.168.3.x (that is, any value with the exception of 192.168.3.100).

  3. Set subnet mask to 255.255.255.0.

  4. Run ethernet cable and connect to generator controller Modbus TCP port as well as ETH1 port on Generac Link gateway.

  5. Contact Support to reconfigure site for Modbus TCP communications.

  • If controller IP address cannot be changed due to site restrictions, please reach out to schedule a session with a Solutions Engineer.

  • If the technician does not have password to change communication setup on controller, reach out to the IDC master tech or to the generator support team.

  • If the technician does not know where to change the communication setup, reach out to the IDC master tech or generator support team.

Replacing an Existing Gateway

  1. Remove power and serial connection terminal blocks, antennae connections, and any Ethernet or other cabling from the gateway to be replaced.

  2. Remove existing gateway from enclosure.

  3. Replace existing gateway with new gateway by reconnecting the terminal blocks, antennae, cabling, and installing in the harness and enclosure.

Data Values of N/A

There may be a gateway-to-network connectivity issue. 

msng-values.png

Possible Connectivity Issue

Steps to Resolve

  1. Confirm that the device is on by checking the PWR light, which should be illuminated and solid (without blinking).

power-check.png

Power and Status Indicator Lights

  1. If the PWR light is off, check red and black wire connections and voltage.

  2. Confirm that the NET light is On. This light indicates if there is an active cellular connection and will blink while registering and illuminate (solid, without blinking) when connected. If NET light is off, confirm that antennae are firmly connected and move to a location with the best possible signal.

The included antenna extension cables can be used to move the antenna outside of the enclosure to improve the signal. If the light keeps blinking, be sure sure the antenna is connected to ANT1 and ANT2 ports of the gateway and the antennae are mounted to a place of maximum cellular coverage.

  1. Cycle power to gateway by removing and re-inserting the inline harness fuse. Wait approximately one minute and check NET and signal lights again.

  2. We also recommend that the onsite technician checks Verizon coverage at the site using Verizon’s coverage checker (https://www.verizon.com/coverage-map/). If necessary, determine if alternative carriers (for example, AT&T or T-Mobile) have better reception in the area. Be sure to reach out to local site contacts.

Values of -99 Populate Data Stream

A value of -99 indicates a Modbus serial communications issue.

Negative 99 (-99) Appears in Data Stream Values

To resolve this issue, be sure to take the following steps:

  1. Check and compare the settings for the following with the controller-specific installation instructions.

RS232 Settings

  • Baud rate

  • Parity

  • Modbus address

For the DB9, be sure to disconnect then reconnect.

Modbus RS485 Settings

  • Baud rate

  • Parity

  • Modbus address

Modbus TCP Settings

  • IP Address: 192.168.3.2

  • Subnet Mask: 255.255.255.0

  • Default Gateway: 192.168.3.100

  1. Confirm proper wiring connections between the gateway and controller.

  2. Power cycle the equipment controller.

Be sure firmware version on PowerZone Pro Sync is 1.23.2 or higher.
