The smart outdoor light controller for Zhaga connector
Presentation

The OLC Zhaga is an outdoor lighting controller, and it can be installed in no time at all on a luminaire head equipped with a Zhaga connector. It is available with a D4i or SR interface, allowing, for example, to dim the lighting, recover energy measurements or detect malfunctions.

Its sleek and small-sized case will perfectly match the aesthetics of your street furniture.

Features

Streetlight control

The controller communicates via a digital DALI2 / D4i / SR interface with the streetlight ballast. These new digital interfaces are advanced versions of DALI, offering more possibilities for inventory management, diagnostics, maintenance, and interoperability between manufacturers of drivers, controllers, and sensors.

Streetlight switching

You can switch on the controller either by using a traditional centralized remote control or thanks to a constant power supply. In the first case, the controller switches on simultaneously as the luminaire; it then starts the application of the configured dimming profiles. The astronomical clock built into the controller plays a central role in the second case. This clock computes the sunset, and sunrise times, according to the streetlight coordinates and the date. On this astronomical basis, you also can incorporate sunset and sunrise offsets depending on the observations made in the field.

Dimming

Light intensity reduction profiles can be configured easily on the remote management software and are synchronized to the controller via the wireless network.

Scheduled dimming
Dynamic dimming
Volumetric dimming

Energy measurements

Thanks to the streetlight D4i driver, you can measure energy consumption and savings. In addition, instantaneous measurements can be retrieved on request: frequency, voltage, current, power, and power factor. The measurement data are stored in the remote management software for analysis.

Fault detection

The controller communicates with the luminaire ballast via a DALI interface. It is thus possible to diagnose several faults such as a light source fault, a short-circuit or an open-circuit, a decrease or increase in the load, etc. Based on the recovered energy measurements, additional faults can also be detected.

Configuration or communication faults

Sensors

The Zhaga NovaLight OLC controller can orchestrate different sensors for streetlights with two Zhaga connectors. Today’s most obvious use is for motion detectors to be installed on the lower Zhaga connector. Other types of sensors will be gradually added to the solution.

Outdoor streetlight controller for Zhaga socket

The NovaLight OLC Zhaga is an outdoor lighting controller compatible with the standardized Zhaga socket. It makes it possible, through various strategies, to dim public lighting when road occupancy is reduced and thus to achieve significant energy savings. Using the energy meter integrated directly into the D4i driver, you can record these savings. In addition, lighting faults are automatically detected and sent to centralized remote management software via a wireless network.

The controller is made of UV resistant plastic. The base is made of polybutylene terephthalate PBT and the translucent smoky gray dome is made of PC polycarbonate.

Environmental parameter Min Typical Max Unit
Operating temperature -30 +75 °C

The controller is powered through the Zhaga connector by the D4i / SR driver of the lamp. The driver also supplies power to the DALI bus. The signal distributions on the Zhaga connector comply with the standard. The luminaires delivered with one or two Zhaga ZD4i certified connectors, including a driver with a 24VDC auxiliary power supply, are pre-wired at the factory so that you can install the Zhaga controller in a jiffy.

The controller is connected to centralized software via a low-data-rate, low-power, mesh-topology wireless network. A mesh topology implies that the communication network initially generated by a NovaLight Gateway access point/router/gateway can be extended by all the connected controllers (signals relayed by the controllers). Controllers can also exchange messages directly with each other. This mechanism is used in particular to create light paths with dynamic lighting.

Frequently asked questions
What is Zhaga?

The Zhaga approach is to entrust the control of luminaires to devices plugged in using standardized connectors. Zhaga provides a solution to historical shortcomings of the NEMA connector, such as size, complexity, tightness, and cost. This approach pools components and functions between the luminaire driver and the controller.

How to install the NovaLight OLC Zhaga?

The mounting of the NovaLight OLC Zhaga controller is implicit. You can install it on a luminaire equipped with a Zhaga socket and ZD4i compliant. Suppose two sockets are available on the head of a luminaire. In that case, we recommend installing the controller on the top while installing a detector on the bottom.

What are the compatible drivers/ballasts?

The NovaLight OLC Zhaga controller is compatible with D4i and Philips SR drivers. The driver must provide the 24VDC power supply. The controller is not compatible with the Osram Dexal standard.

How to commission the NovaLight OLC Zhaga?

You must register the NovaLight OLC Zhaga in the remote management software to be operational. To do this, we recommend that you use the NovaLight mobile application with whom you can select/create a light point, scan the product barcode required for its registration, and enter the product details. Once you have referenced the controller in the software on its corresponding light point, as soon as you power on the lighting infrastructure and the NovaLight Gateway router, the controller can connect to the remote management software to receive its configuration.

How do I know if the product is working?

The ideal approach is to verify proper operation through the remote management platform, either through the web interface or mobile application. If you switch on the luminaire and the lighting network, it is possible to make instant manual checks. Changing the light intensity and checking the energy data makes it possible to certify that the dims are working correctly. On-site and during the day, the controller will generally switch on the luminaire. However, this depends on the setback schedule configured. For example, the program can activate the astronomical clock function, which will switch off the lights during the day.

Can this controller manage multiple streetlights?

The controller can perform diagnostics for up to 12 different streetlights on the DALI bus. The controller will only transmit general commands that will impact all the lights uniformly in terms of intensity control.

Can Zhaga sensors be used?

Yes, connecting a Zhaga D4i sensor to the NovaLight OLC Zhaga controller is possible. The sensor must be D4i certified.

Can the Zhaga NovaLight OLC apply volumetric or dynamic dimming?

Yes. You can integrate the NovaLight OLC Zhaga into a volumetric dimming strategy. This controller does not host integrated detectors for dynamic dimming based on motion detection. However, it can still react either to a D4i sensor connected to the streetlight or detections from other controllers.
