Green light for safety at work

November 2013 Sensors & Transducers

The MLD series multiple light beam safety devices manufactured by Leuze provide comfortable and efficient safety in the workplace. The devices offer unobstructed material passage while simultaneously ensuring constant personnel protection.

“These devices are ideal for use in potentially hazardous areas around machinery and in production and processing plants. Customers can select from a variety of function classes to determine the performance and safety levels they desire,” says Gerry Bryant, managing director of local Leuze distributor, Countapulse Controls.

These new versions of Leuze’s MLD multiple light beam safety devices incorporate a coloured indicator which is visible from a distance and displays the muting status as well as output signal switching device (OSSD) and error states. Together with the OSSD message output, direct and simple diagnosis is possible both visually as well as via the downstream PLC.

Configurable muting

The Leuze MLD safety devices have six different muting operating modes. Configuration is performed via either wiring or pin assignments at the plug and socket, substantially simplifying the setup of the sensors. In addition to the two- and four-sensor muting for parallel or sequential applications, customers can also implement partial muting. In this instance, the lower beams can be muted while the upper beam remains active.

If a muting signal is received from the system, the operator can use the 8-pin machine interface plug directly on the sensor, which reduces cable requirements. The muting enable function also allows customers to enable or disable the muting sequence via an external signal, resulting in increased security against tampering.

The devices include a switchable range of 20 to 50 metres as well as an integrated laser alignment aid, which can be operated with a button or MagnetKey. The sensors are available in two-, three- and four-beam transmitter receiver systems as well as in two- and three-beam transceiver systems with a range of 0,5 to 8 metres.

“In addition to their emphasis on safety, the sensors are designed around ease of use. There is a direct connection to the AS-I bus, eliminating the need for additional coupling modules. All configurations of the muting modes can be made without using a PC and the seven segment display allows for quick and easy determination of the sensor behaviour as well as appropriate counter measures. The swivel mount allows the sensor to be flexibly turned 240° on its axis and the clamp brackets provide flexible adjustment when the sensors are used in device columns,” Bryant concludes.
