Gavita Master Controller EL2 Gen2
Lighting control at your fingertips! The Master controller EL1 and EL2 Gen2 are our entry-level systems for centrally controlling large rooms with e-series fixtures. The second generation of Master controllers features improved and expanded functionality that raises the bar:
- Non-volatile memory- Event logging- Independent sunrise and sunset settings- Independent light cycles on the EL2
Now you have complete control over the light cycle and the output of your fixtures from one single point. Never reach to a ballast again!
Setting up the controller is a breeze, with a 5 language text interface in plain language on a high quality OLED display.
Allowing to program two different, and overlapping cycles, for example, a 12/12 on channel 1 and an 18/6 on channel 2.
The logging functionality provides insight in the current and past status of your lights and alarms.Logging functions for high/low temperature, last autodim event, last shutdown event and last power loss.
Set different times for sunrise and sunset.
In extreme conditions the Master Controller automatically dims your lights, so your plants will survive the high heat.
Nonvolatile memory to store user settings.
The complete installation is plug-and-play. Every e-series fixture comes with all necessary cables to install it on the e-series control bus.
When cooling or ventilation fails, the Master Controller automatically switches off your lights, preventing imminent damage to your crop (or worse).
The ECMs (External Contactor Modules) are used to switch on or off auxiliary equipment during the lights-on or lights-off period. In the GEN2 EL2 controllers you can now choose whether they switch on or off, and which channel they should follow. This allows for flexible integration and automation.
Gen 2 improvements
Memory – All master controllers use dependable, non-volatile memory to store user settings.
Logging – All master controllers now have logging functions for high/low temperature, last auto-dim event, last shutdown event and last power loss, including the event’s date and time
Separate sunrise/sunset control – Set different periods for sunrise and sunset
Independent cycles on EL2 models – These cycles let you program two different, overlapping cycles (for example, a 12/12 on channel 1 and an 18/6 on channel 2).
Independent programmable External Contactor Modules (ECMs) – In Gen 2 EL2 controllers, now you can choose whether they switch on or off and which channel they follow. The results? Flexible integration and automation.
EasyThe Master Controllers are extremely easy to set-up. The two-line green OLED display is sharp and easy to read, even in a high light intensity environment, and all menu items are in plain text. The 4-button control of the menu system is intuitive. A special fifth button is added to directly set the output of your fixtures. Red and blue LEDs show you the output status of your controller ports and give you a quick view of any errors.The wiring system is plug-and-play with all the cables you need already included with each e-series fixture. The manual describes how you can make custom cables for any length. Different lengths of control cables are available as original Gavita accessories. Be aware that the Gen 2 Master controller comes with a 15 V power cord which differs from the 5 V power cord that is being used with Gen 1 Master controllers. You can find more information on how to connect your fixtures to our controller here: Single Bus vs. Repeater Bus
The controller is easy to mount with the supplied bracket. Two screws are all you need to install it and the controller clicks right in. This enables you easy access to the wiring at the bottom of the controller.
SafeThe most important and valued features of the Master controller are the temperature safety features. Your lamps will automatically dim when your climate control is no longer able to maintain the correct temperature. Or will even shut down your lamps when a maximum temperature is reached. These features have saved many crops already!The control signal is a safe, analog and low voltage signal, and the controller is protected from signal shortcuts in the wiring. Wiring faults will not kill your controller.Last but not least, the EL2 offers you alarm contacts (NO and NC) to seamlessly integrate your controller in your alarm and monitoring systems. Whenever there is a calamity (power outage, emergency shutdown or sensor failure) the alarm contacts will switch, notifying you of the fact that you need to take action.
FlexibleWhether you control two fixtures or 1000, the Master Controller will do the job. Standard, each output channel can control 40 fixtures (Single Bus e-series) up to 500 fixtures (Repeater Bus e-series), without the addition of booster modules.
The EL2 has even more features. On top of the double output ports, you can connect our ECM units which allow you to switch auxiliary equipment, such as CO2 units and heaters, during the lights-on and light-off periods.
We have a wide range of original Gavita accessories available, ranging from a booster to expand the number of single bus e-series fixtures with 200 fixtures each, to cables, splitters, and long lead temperature sensors.
SexyThe anodized aluminum extrusion housing is rugged and compact. No more standard grey plastic installation boxes with cluttered buttons and lights. The controller is compact, clean, and some even find it sexy.
