Before Installation
How to Install the LightGrid 2.x Controller
(The GESEM65-3 module is pictured below, however the instructions are applicable across the entire Select TX
TM
Gen3
family of modules.)
•
Carefully unpack unit. Inspect for defects before installing.
•
Check electrical parameters.
Ensure that the fixture operating wattage is below 1000W, and the voltage at the
pole is within the allowed range of the Controller (range is listed on the sticker on the bottom of the controller).
Using controller outside these parameters will void its warranty.
•
Verify that power to the luminaire is ON 24/7 constant power.
The LightGrid mesh will not operate properly
when operating on switched power from a master timer or photocell.
•
Confirm that the controller is the correct network ID for the system it is intended to join. This will be on the
sticker on the bottom of the node, labeled as Net A, Net B, Net C … this must match the other controllers in the
area or the node will not join the network.
•
Install the gateways first. The startup and formation of the network is faster and smoother process when the
Gateways are installed before starting to install Controllers.
•
Plan an installation route. Generally it is best to install controllers nearest to the gateways first, and then proceed
outwards.
Check nearby poles. At the pole to be installed, confirm there is either a Gateway or another active LightGrid
Controller within 1000Ft. This is important, to make sure the node has a connection path for communications
and is within its RF range limits.
Ensure Cellular Service is Accessible: Prior to installing cellular nodes verify with LightGrid support team that
cellular service is available at the location, providing latitude and longitude coordinates.
Plug in the node: Orient controller so large blade aligns with large slot in receptacle. Plug in, then twist
clockwise until it is fully locked in place (Figure A).
Confirm the fixture dims during the first 60 seconds. When the controller is first plugged in, it will turn the
luminaire ON and will then dim the luminaire. Before leaving the pole, you must visually confirm that you see
the brightness of the luminaire drop, in order to confirm that dimming is working properly. Note: applies only to
dimmable fixtures with an ANSI 5 Pin or 7 Pin socket. Fixtures with a standard 3 Pin socket will not be dimmable.
Orient the Controller towards North: Lift up on the controller, which will also lift the receptacle with it. While
lifting, rotate the controller and socket until the word North on the top of the controller is directed toward true
North. Then lower the assembly back into place (Figure B).
Make sure red and yellow indicator LEDs are blinking. This confirms the controller is looking for a network to join.
