CONTROL SYSTEMS + AUTOMATION

Automatic transfer switch controller for motorised switches Control Applications is now marketing a new ATS changeover system, the ELNet CO which features an advanced, user-friendly, interface – the signature of all ELNet products. As its name suggests, this ATS controller is designed for changeover between two power sources, inmost cases: the electric utility and local generator. Featuring a built-in voltmeter, it eliminates the need for no-voltage and delay relays, selectors, control relays and naturally volt-meters. Fea- turing Alarm and Event History Logging of up to 1 000 alarms/ events and full open protocol

communication, supportingModbus and BACnet via a RS485 port it is the ultimate changeover solution for BMS integration. Other features include Double Interlock Protection, preventing simultaneous activation of both power systems, and a menu-driven graphic display (320 x 240 mm). All operational parameters are adjustable and as a bonus fea- ture you may find Self-Check Mode, enabling auto-confirmation of proper wiring installation. Enquiries: Control Applications (Israel).

Multifunctional display – speed, time, counter Themultifunction display shows various measured values in industrial automa- tion. It uses the principle of interval measurement to processes input pulses. The scaling factor allows (rotational) speed and processing time, etc. to be calculated, displayed and converted into an analogue signal.The unit can also act as a counter or an industrial timer. Five different operating modes, optional analogue and switching outputs as well as the convenient display make the multifunctional evaluation system fit for various applications in industrial automation.

Optical data transmission The Leuze DDLS 500 optical data transmission photoelectric sensor is so much more than an optical sensor.This innova- tive sensing device offers many more features that make it both efficient and simple to use. Through continuous monitoring of the receiving level, the user can be alerted to an impending failure in good time. Available from leading sensor solutions supplier, Countapulse Controls, the Leuze DDLS 500 enables the transparent, contact- and wear free transmission of data over distances of up to 120metres in 100 Mbit/s real-time.This is achieved by using an invisible infrared laser which communicates bi-directionally between devices. The sensor is ideal for all applications where data needs to be transmitted without cables, andmore importantly without interference. It is favoured for applications where mechanical systems are pushed to their technical limitations. To permit fast visual control, the Leuze DDLS 500 has an LED display that is clearly visible from a distance of 200 metres. All relevant information is precisely depicted on the control panel.The device’s patented single hand adjust-

ment process and integrated mounting plate with alignment screws enables easy mounting by just one person.This makes it easy to install, and the aid of an integrated laser alignment and level facilitates rapid align- ment, even over longer paths.
