In light of the current Covid-19 Pandemic, we have been getting several questions about guidelines for HMI cleaning and sanitation. We’d like to take a minute to share with you the information provided by Rockwell Automation.
The below is a summary of the information as we’ve learned it, but I encourage you to follow the links and read the guidance from Rockwell Automation in full.
Most of these units are Responsive Touch Panels so it is important to use careful selection on your cleaning solution. Recommendations for HMI cleaning are to use a soft lint-free cloth that is dry or lightly dampened, not soaked, with a mild cleaner (neutral pH, not acid or alkali) on the cloth. Do not apply the cleaner directly to the face of the HMI. When cleaning be gentle and avoid the edges of the glass or film.
A compatible chemical to use to clean all Rockwell Automation/Allen-Bradley HMI products is isopropyl alcohol (not to exceed 70% concentration). Additionally, while Rockwell is NOT making recommendations on the types of sanitizing cleaners that should be used to prevent the spread of COVID-19, they have provided the following list of chemicals, by product family, that have no functional effect on terminals (known cosmetic effects are also listed where tested):
Words of caution from Rockwell Automation:
Many products contain ammonia, phosphates, and/or ethylene glycol, which areReference: QA3878– Rockwell Automation Knowledgebase
NOT ACCEPTABLE; check product content label carefully.
Additionally, last year Rockwell introduced a PanelView Plus 7 Hygienic Design, certified by the National sanitary Foundation (NSF) designed for food, beverage and pharmaceutical industries where HMI cleaning is paramount. It is IP69K rated to survive high temp/high pressure washdowns as well as conformally coated, something to consider if you feel there will be lasting changes to cleaning. Let us know if you’d like a quote on one to consider.
We hope this helps – stay safe, stay healthy!
