Dry Conveyor Safety Upgrade

Upgrade the client’s safety mechanisms to meet corporate standards. Sever mixers were individually upgrades with new safety circuits. The existing e-stop pushbuttons, new sampling lid safety switches and new hand dump station hardware were interlocked with the ribbon and smizer motors while simultaneously interlocking the software with the CO2 supply.

When the monitoring relay senses an issue with an interlocking device, 480 VAC and 120 VAC control power will be removed from all ribbon and smizer motors. When the monitoring relay senses and issue with an interlocking device, software will turn off all outputs to the CO2 valves. PLC and HMI programming associated with the safety upgrades are new field devices met the customer’s scope.
