Installation & Wiring Instructions
The 4 channel lightLINK modules are designed for mounting in electrical control cabinets and should be enclosed due to the exposed terminal design. If DIN rail is not available, brackets include mounting holes for surface mounting.
Wiring terminals are “pluggable” blocks and can be removed from the module by pulling the terminal block away from the module face. This is convenient for wiring and for replacing a module in the event of a failure without the need to remove wiring from the terminals.
HUB Connection Port: RJ-45 connector port for power & data.
Output Terminals (x4): analog 0-10Vdc outputs for operating ballast dimming signals, variable speed drives, and other devices with an analog voltage control input.
Mobile App Setup Guide
- Plug in your Growlink device to power it on. The LED should be blinking blue. If not, hold the SETUP button until status light flashes blue rapidly (12-15 seconds).
- Download the Growlink app from the Apple App Store, or Google Play Store.
- Go to Growlink.com/signup and create a Growlink Account:
- After creating your account, a verification email will be sent from ‘no-reply@growlink.com’ to the email address set for your newly created account. One must verify your email address in order to utilize your newly created account.
- Open the Growlink Mobile App and login to your newly created and verified account:
- Once logged in, tap on the settings icon in the top right corner and then tap Add New Hardware.
NOTE: The first time using the Growlink app you will be prompted to allow Bluetooth access. This is required to set up newer Growlink controllers.
Since the 4 channel lightLINK requires a LINKS Hub to function, one will add the 4 channel lightLINK to an existing LINKS Hub using the ‘Add New Device’ option in the add hardware page.
Add New Devices to an Existing Links Hub
- To add new devices to an existing Links Hub, go to the ‘Add New Hardware’ option within the Settings menu, and select the ‘Add New Device’ option in that page:
- The Links Hub will now iterate through the list of currently connected devices one module at a time and populate what devices have yet to be registered to the Links Hub. It is important to connect Links modules to the Hub one at a time.
Sensor Modules like the Canopy Link will display their sensor readings, and their associated sensor names can be renamed if desired:
Device output modules like the Relay Link will have a Device name and device type field per output, which allows the user to rename the output and device type to match the device being controlled by the output:
Lighting Control modules like the Digital Light Link will have a ‘Manufacturer’ drop-down list, where the user can specify the make of lights connected to the module:
- To skip a specific module from being registered to your Links Hub, tap the ‘Skip’ button at the bottom of the wizard:
- Once the sensor or devices have been named to your liking and any required fields for the module have been designated, one can tap the ‘Add & Next’ button to move onto the next module detected by the Links Hub:
- Once all currently detected modules are registered or skipped, a final confirmation window will populate:
- If you wish to add an additional Links module, connect the module to the Links Hub while at this screen. Once detected, one will be able to setup the sensors and devices of the connected Links Module.
If all desired modules have been added to the controller registration click the ‘I’ve Registered All Connected Devices’ button to finish the setup wizard.
Troubleshooting
Controller not showing up on my list of devices to connect:
Check your phone or tablet and ensure Bluetooth is enabled.
Hold down the Setup button located on the controller (see image below) for approximately 12-15 seconds until there is a rapid flashing blue light. Then refresh the device list on your phone or tablet.
Unplug the unit for 10 seconds and then plug the device back in and wait for the LED lights to stop changing colors (typically 15 seconds). Then refresh the device list on your phone or tablet.
Controller didn’t connect to Wi-Fi:
If unsuccessful in the first attempt to connect the controller to the Wi-Fi network, hold down the Setup button located on the controller (see image below) for approximately 12-15 seconds until there is a rapid flashing blue light. Once rapid flashing becomes visible, immediately release the Setup button. This will put the controller into Listening Mode (Blinking Blue). Now, restart the connection process outlined in the Quick Setup Guide section above.
The Wi-Fi network being used has changed:
In the event the controller needs to re-connect to an existing or new Wi-Fi network, put the controller back into Listening Mode (see above) and follow the Controller Connection process outlined in the Quick Setup Guide section above.
