Finder Relays (10 Series) for Automatic Lighting Control Feature Unique Light Feedback Compensation

Finder.jpg

Finder has announced the new 10 Series light dependent relays, which have the ability to control lighting according to ambient light levels. These relays will be of particular interest to designers, specifiers and installers both of lighting and of lighting control systems, and will find applications in the automatic control of exterior lighting around factories, loading bays, schools, offices and similar areas where lighting is required for security or safety reasons during the hours of darkness.

FIN0056_10 Series.jpg

There is a growing need to reduce energy consumption, maintenance and replacement costs by ensuring that essential exterior lighting is lit only during times when the ambient natural light falls below an acceptable level, and it is this requirement that the 10 Series has been developed to address.

The 10 Series relays feature an integral photoelectric sensor combined with innovative light feedback compensation circuitry designed by Finder, which prevents the controlled lighting from ‘hunting’ on and off due to the perceived increase in ambient light when lights are automatically turned on. This feedback capability is achieved by monitoring the effect of the controlled lighting over a ten-minute period, which ensures compatibility with slow starting gas discharge lamps. ON and OFF delay times are reduced to zero for the first three cycles, which aids set up and commissioning and reduces installation time.

The new family of relays includes both single-pole and two-pole output types rated at 16A, and also a miniature type, 10.51, with a single 12A output. The double output 16A 10.32 allows Live and Neutral switching, while model 10.41 has a single 16A NO output for Live switching.  All the relays in the series operate from either a 120V or 230V AC supply.

The ambient light switching level is adjustable in the range 1 – 80 lux, and the relays are capable of switching up to 2.3kW of incandescent or halogen lighting, allowing the switching behaviour to be optimised according to both the needs of the individual application and the physical location of the unit.

Electronic Step Relay from Finder Eases Control of Multi-Point Lighting Installations

 Finder.jpg

Finder has announced the introduction of the 13.81 electronic step relay, which is designed for the pushbutton control of lighting. This step relay is particularly suited to complex multi-point installations.

FIN0053_1381.jpg

The desire for more sophisticated and flexible control of lighting, coupled with the need to reduce material and installation costs, is influencing consultants, designers and installers of lighting control systems to consider using electronic relays, especially for applications where quieter operation than that of conventional electromechanical step relays is desired. They will be able to use the 13.81 electronic step relay in locations that have multiple entry points, or in large areas where a number of switching positions are required for the control of lighting. The unit will be of particular interest to lighting designers who wish to achieve easy central control of multiple light fittings.

The 13.81 allows the connection of up to 15 illuminated push buttons, to enable multiple switching points to be served with a minimum of wiring, and is capable of switching up to 3kW of incandescent or halogen lamp loads. Indirect control of lighting – isolated from the AC mains – means that lighter gauge wiring can be used between pushbutton and relay, while electronic operation is much quieter than conventional electromechanical switching and offers a longer life. The cable run between the pushbuttons and the relay can be up to 200m in length, providing flexibility of mounting location, especially in large areas such as warehouses and factories.

The 13.81 is housed in a compact 17.5mm wide enclosure for 35mm DIN rail mounting, and is suitable for consumer units.

Arcolectric Temperature Micro-Logger

ARCOLOGO-2004_140px1.gif

Arcolectric have introduced the Temperature Micro-Logger, an intelligent panel mounted device that monitors and stores temperatures for downloading over a wireless data link.
 
The device is ideal for applications where monitoring process temperature is important, particularly within the food preparation industry. It is especially useful for food storage, retail displays and prepared food outlets where accurate record keeping is essential. The Temperature Micro-Logger adds advanced logging functionality to a food storage unit for little cost increase, much smaller than would be expected by the end user. 

 temp-logger.jpg

The Micro-Logger provides a clear and simple visual indication of the temperature conditions within the piece of equipment, utilising a simple go/no-go display principal. Blue LED illumination indicates when process temperatures are within safe limits. The display changes to a Red indication if the safe temperature limits are ever exceeded. Temperature measurement range can be set between -30ºC and +80ºC.
 
Designed for quick installation, the Micro-Logger has an industry standard snap-in profile, with a temperature sensor on flying leads for convenient remote mounting. The product can directly replace the mains neon indicator usually found on freezers, refrigeration and cold storage equipment, providing a fast, cost-effective upgrade of non-compliant or un-monitored equipment.
 
The temperature data is logged into an internal non-volatile memory at user programmable time intervals ranging from 1 second to 12 hours. Up to 14,000 measurements can be stored. The data can be downloaded via the built-in wireless infrared communication port using a PDA, Notebook or laptop computer and is time and date stamped, simplifying reporting and providing documented evidence of historical storage temperatures.
 
Retailers and producers need to ensure food products are kept at the recommended safe temperatures, and for self-protection, adequate temperature records must be kept. Complying with the relevant food storage regulations does not lay with the equipment manufacturer; it is the responsibility of the equipment end user. The addition of the Micro-logger to an item of food storage equipment enables manufacturers to supply added value to end users, and a facility to contribute to complying with the regulations.
 
The Micro-Logger carries UL, CE and FCC approvals

Leading Desert Lights – CML Innovative Technologies Rides Away to Saharan Success

CML LogoB.JPG

February 2006 – In order to test new LED lighting concepts, CML Innovative Technologies equipped three KTM enduro motorcycles with LED lighting system prototypes for the inaugural “Desert Logic” rally for such motorbikes. Philippe Gosselet from CML-IT in Besançon, France, one of the company’s engineering centres of excellence for light design, kitted out the bikes for the rally. He also formed part of the CML-IT/KTM team riding them to a winning position after seven days and 1000km in the desert of southern Tunisia.

CML Desert Logic2.jpg

All LED lighting systems used on the motorcycles were specifically designed to withstand the difficult environmental conditions in the desert (big temperature changes from very hot at day to very cold at night, high winds containing grains of sand and constant shocks and vibration from riding in sand and over dunes). Due to the low power requirements of the LEDs, the batteries of the bikes experienced only minimum drain from CML-IT’s LED lighting systems.

Each motorcycle featured a high power LED brake light offering increased security in conditions with limited visibility. A LED system illuminating the roadmaps with high brilliance white LEDs ensured roadmaps were readable in all lighting conditions. A rheostat enabled the system to be adaptable to ambient luminosity. A security system consisting of two high power LEDs blinking consistently at the front and back of the bikes allowed the riders to be seen in the pitch black of the desert nights.

Created and organized by Fabio Fasola, Italian specialist of enduro and long-distance motorbike rallies, the first “Desert Logic” enduro motorbike rally took place from December 3 to December 10, 2005 in South Tunisia. The venue for this first event, which totalled 1000km of links and specials tests, was the oasis of Ksar Ghilane.
