Sensor-operated LED lights for control cabinets in the field of batch and cullet plants

The Challenge

Zippe Industrieanlagen GmbH, based in Wertheim, Germany, is the world's leading supplier of batch and cullet plants for the international glass industry. Zippe is also a specialist in weighing system solutions. Through focusing and specialisation, Zippe has acquired extensive expertise and a wealth of experience. With six subsidiaries and 16 agencies worldwide, the company is represented in all major glass industry markets. Each project presents the experts with new challenges – no two technical solutions are the same.

Zippe's many years of experience enable it to meet special requirements competently and reliably. As a central control system for all products, control cabinet solutions that are precisely tailored to requirements are indispensable. 
Perfect illumination of the control cabinets is particularly important. And this is where häwa GmbH comes into play, with which Zippe has been successfully cooperating for decades.

The häwa Solution

For more than 20 years, häwa has been Zippe's standard supplier of modular cabinets. As a result of many years of trusting cooperation, häwa is always the first to approach Zippe with newly developed products and is guided by the customer's requirements. The new LED light was also initially sent to Zippe as a sample, where it was put through its paces and ultimately deemed the optimal solution. Since then, the light has been installed in every control cabinet delivered in all areas, such as weighing system solutions, batch plants, cullet returns and charging technology at the melting furnaces.

Optimal illumination is important to create a suitable work environment at the control cabinet. Lights must function reliably, especially when a system malfunctions or breaks down, the technician on site depends on it. With the sensor-operated LED light SOL 704, häwa offers the optimal solution. The LED light is perfect for illuminating control cabinets and is suitable for häwa free-standing cabinets and other manufacturers' cabinets with 25 mm grid perforation from a width of 600 mm. The pre-set proximity sensor is ready for operation immediately after the light is mounted and switches it on immediately when the door is opened and closed and off with a delay of five seconds. It is possible to connect further devices or components such as air conditioners, filter fans and signal towers to the sensor-operated LED light using the potential-free contact of the opener and closer. This eliminates the use of an additional door contact switch and minimises the wiring effort. The on/off function is controlled by the luminaire's sensor. As soon as it is connected, it also switches the applications on and off when the door is opened and closed.

Up to ten luminaires can be connected in series, making the product particularly user-friendly, as large switch cabinet interiors are illuminated homogeneously and evenly. In particular, the use of modular cabinets, such as those from Zippe Industrieanlagen, is significantly simplified. The luminaire, which has an IP 20 type rating, is available in two voltages, 24 V DC or 120 V – 230 V AC; the AC versions are optionally equipped with a socket. The power consumption is between 12 and 16 watts. The use of LED technology means that the luminaires have a very long service life. They can be mounted either by screwing them on or using a magnet.
