Advanced multi-function light curtains without dead zones
16 February 2014
The new PSENopt Advanced light beam devices from Pilz allow the highest flexibility thanks to their multi-functionality: muting or blanking and cascading are implemented within the same light beam device.
Genuine 'no dead zone' at top and bottom, manual or software configuration and logging are additional features which differentiate these new light curtains from Pilz's existing basic range.
The main feature of these light curtains is that they can be manually or software configured for standard, blanking or direct muting capability, with the bonus of cascadability - so one light curtain for all functions, for more complex applications.
The fact that the top and bottom beams are at the very extremity of the receiver/transmitters means there are no dead zones, allowing these light curtains to be fitted into tighter spots without extraneous housing getting in the way.
The new Advanced range consists of 33 types covering Type 2 hand (30mm) and Type 4 finger (14mm) and hand (30mm) resolution, at protected heights ranging from 300mm to 1800mm, with operating range of 0.5 to 20m.
The light curtains are supplied with sliding fixing brackets, and a separate cascading bracket it also available. Reaction times are as fast as 11.9ms.The devices TUV certified to EN 61496-1 and IEC 60508 to SIL 3 and EN ISO 13849-1 to PLe.
Connections can be made at the top or the bottom of these light curtains via easy to fix 18 pole pigtail leads, of which there is an emitter type and two receiver types, one for normal or blanking use, and one for muting which will accept two independent, hardwired muting inputs (as required in IEC/TS 62046) directly into the receiver.
Greater programming flexibility is available in ACM (advanced configuration mode) using an Ethernet interface adaptor and the free to download PSENopt Configurator (found here). In this mode up to 5 fixed blanking zones can be set, and the number of floating blanking beams is selectable. Muting options can be set here too (cross beam, parallel beam, muting period, override, etc).
