Meyn incorporates Pilz safety controls

17-06-2009 | |

Meyn America LLC, manufacturer of poultry processing equipment, has dramatically reduced line downtime caused by frequent equipment washdown, by upgrading conventional safety controls, the company said.

This was accomplished by working with engineers from Pilz Automation Safety L.P. to upgrade conventional safety relays to a modular safety controller.
Meyn America was so satisfied with Pilz’s effective safety solution that it will include the upgraded PNOZmulti safety configuration on all new poultry processing lines it sells as well as in a retrofit kit to existing customers.
Dale Stolzfus, Meyn’s vice president of aftersales said: “It will reduce our customers’ downtime due to troubleshooting by at least 60 to 70 percent. The ultimate results are higher productivity and lower cost of production for customers.”
Meyn America’s previous safety system used conventional relays. When water caused a fault that stopped the line, a single, general e-stop alarm was displayed. All e-stop switches and cables had to be manually controlled, which took a lot of work and time.
It was this issue of lengthy troubleshooting time that brought Meyn America into consultation with Pilz.
Pilz engineer John Kneynsberg recommended upgrading the conventional safety relays to modular safety controllers.
Meyn America engineer Dustin Addison selected the Pilz PNOZmulti modular safety system to control the e-stop switches because “it has unique features that allow it to identify the specific e-stop button(s) at fault.”
When water causes a fault in the safety system, the line is stopped and specific diagnostic information is displayed on the control panel.
By identifying only the information the maintenance technician needs to remedy the fault, time is saved and the line can be restarted quickly and easily, company officials said.
Meyn America will include the upgraded PNOZmulti safety configuration on all new poultry processing lines it sells and market this the system as its “New Emergency Stop Control System.”
