MyPNOZ technology will be the focus of Pilz Australia’s stand at APPEX. The technology is a proven winner for food manufacturer Haco AG.
The company simply wanted to integrate a new labelling laser into an existing coffee filling line. However, the installed safety relay could not be expanded any further.
An alternative expandable, modular solution was therefore to be used, while the downtime and associated loss of production was to remain as low as possible.
With its new, simple configuration, order and commissioning mode, the modular safety relay myPNOZ offered Haco a rapid, customised safety solution, tailored to their individual requirements and operational almost from the start.
“The safety relay myPNOZ was exactly what we were looking for at that time – a suitable solution that could be integrated with practically no downtimes,” said Piotr Grzelinski, electrical design engineer at Haco.
“myPNOZ opened new opportunities for us to implement tailor-made solutions. The individual ‘pay-what-you-need’ approach offers an optimum cost-benefit ratio.”
After a brief conversion period, operators on the filling plant’s turntable are not only protected from the hazards of the laser, but also from the drives’ hazardous overrun: the inputs of the dual-channel emergency stop and the OSSD signals of the safety gate systems PSENmlock are connected directly to each other on the myPNOZ, creating a safety zone, which comprises both the actuator technology – including the powered turntable– and also the laser.
The required functionality was entered and ordered via the myPNOZ Creator. A total of five modules were required to safeguard the workstation at the turntable – the head module for the safety circuit on the employed emergency stop pushbuttons, an input module for the safety gate systems and three output modules for the actuator technology.
